Further Reading: Arthroscopic Surgery using the McCain Technique – A New Option for Conservative Management of the Problematic TMJ

We are pleased to announce that the Cincinnati Center for Corrective jaw Surgery is now offering arthroscopic surgery to care for patients who present with jaw joint problems unresponsive to conservative management. Problems can include pain, limited opening, and internal TMJ conditions that range from clicking and locking of the joint to painful degenerative arthritis.

Size matters when it comes to successfully treating joint problems with arthroscopic surgery. The TMJ is not only small but it is surrounded by important anatomic structures that must be protected during the process of inserting the arthroscope and maneuvering it to fix the problem. Making arthroscopic surgery of the TMJ so challenging is the fact that the nerve that controls the movement of the facial muscles runs close to it in the tissue overlying it. Also, the middle ear sits just behind the joint so gaining entry to the joint without damaging the middle ear is tricky.
The TMJ is so small that it holds less than a teaspoonful of fluid. It is hard to believe that a joint so small with so little in it could cause so much pain and so much misery for so many people. Joint problems include clicking and popping in the joint with opening and closing of the mouth and pain from displacement of the joint disc. In other joints like the knee and shoulder these symptoms can be decreased by cleaning out inflammatory chemical particles in the joint and placing medications in the joint to lubricate it and decrease inflammation in the lining of the joint space. But unlike other joints, accomplishing this feat has been problematic because of potential complications with middle ear and surrounding nerves to the face and because of the relative size of the join to the size of the arthroscope going into it.

With the introduction of the McCain Arthroscope and the McCain Arthroscopic Surgical Technique, many of the complications with arthroscopic surgery of the TMJ have been greatly reduced.

This spring, I introduced the McCain Arthroscopic Technique and the McCain Arthroscope designed by Dr. Joseph McCain of the University of Miami. The arthroscope designed by Dr. McCain is unique for its size and ease of use. Dr. McCain is broadly recognized as one of the founding fathers of TMJ arthroscopy. I was trained by Dr. McCain in late winter of 2016 and during the spring of 2017 and I follow the McCain Technique for TMJ arthroscopic surgery.

The arthroscope Dr. McCain designed is special. He has been involved in the design since 1990 and the current scope is the result of a group of skilled engineers in Germany who designed the scope to Dr. McCain’s specifications. The scope has the most sophisticated optics available in small joint arthroscopy and provides excellent images given its micro size of 1.8 millimeters. Sixteen arthroscopes could be set side by side within an inch! See figure 1.

In figure 2, a healthy meniscus is seen overlying the condyle as it translates on the slope of the eminence to maximal opening. In figure 3, the hyperemic tissue of the posterior attachment is seen in a painful joint with anterior displacement of the meniscus upon opening.
The McCain Technique is minimally invasive. The procedure is quick and very effective with a success rate of 90%. More importantly it is safer than previously described arthroscopy techniques. The joint approach Dr. McCain teaches minimizes failed entry into the joint also minimizes complications associated with improper placement of the scope in the small upper joint compartment. Also, the small diameter of the scope allows for more mobility of the scope in the joint space which means more opportunity to break adhesions and clean inflammatory debris out the joint space.
According to the American Association of Oral and Maxillofacial Surgeons, 35 million people in this country suffer from varying degrees of TMJ dysfunction or TMD. Approximately 10% of this group will seek treatment for joint symptoms that do not respond to conservative therapy. The other 90% can be well managed with conservative therapy, therapy that can be initiated by and managed by the family dentist.

Our treatment algorithm begins with the dentist:
A. Prior to our consultation with the patient, we ask that the dentist fabricate an occlusal guard for the patient and initiate conservative treatment for any overlying muscle overloading or joint overloading as a result of clenching and bruxism.
B. If the dentist is comfortable with the management of the patient’s pain thru the use of anti-inflammatory medications, we request that these medications be added to the treatment regime if not contraindicated for medical reasons. Ibuprofen is to be avoided because of its anti-chondrocyte activity.
C. Amitriptyline or Clonazepam can be given by the dentist to decrease nocturnal bruxism. Clonazepam should be used only for one week as a trial. Patients who respond to it should be switched to Amitriptyline thereafter.
Most patients will be successfully managed at this point but those who continue to have pain need a referral to our office and further work up. These patients usually continue to suffer from:
1. Painful palpation of the lateral capsule of the TMJ.
2. Painful clicking, grating or popping of the joint
3. Painful opening or lateral movements of the lower jaw.

At the patient’s initial appointment I and my staff will evaluate them and obtain a history of their conservative treatment. Traditionally we will add or adjust medications and initiate aggressive physical therapy. To aid in our diagnosis, we will obtain a CBCT of the joints and, based upon our findings, consider an MRI scan following ADA protocols for imaging to determine meniscus status and position.

After further diagnostic imaging and targeted physical therapy we will see the patient back in our office and evaluate their progress. If less than sufficient from the patient’s perspective I will suggest minimally-invasive arthroscopic surgery if it is warranted from the findings of our imaging studies. A diagnostic arthroscopic procedure includes complete lavage of the superior joint space, a 7 point arthroscopic examination of the joint and installation of Na+ Hyaluronate along with a stem cell aspirant, platelet rich plasma or steroids. Successful treatment nears 90% in patients who have been properly worked up and well managed with conservative therapy.

To be sure, arthroscopic surgery of the TMJ is to be reserved for refractory cases of TMD. Proper vetting of the patient and strict adherence to accepted conservative management principles is key for success. While other conservative treatments such as two needle lysis and lavage of the TMJ are known to be successful, my preference for the McCain Arthroscope and Arthroscopic Technique is based upon the following reasons:

1. Minimally invasive entry into the joint with the McCain Technique
2. High success rate for superior joint puncture and navigation of the joint space owing to the small ( 1.8 mm) size of the arthroscope
3. Superior camera optics for the size of the scope allowing for accurate diagnosis of disc position and synovial tissue disease.
4. Second needle visualization in the joint to ensure complete irrigation of the joint space and removal of joint debris.
5. Easy second needle switch to second port for the introduction of instruments to debride the joint and release adhesions.
6. Direct visualization and the instillation of medicaments.

Dental Implants for a New Holiday Smile

Dental Implants for a New Holiday Smile

It’s hard to believe, but the holiday season is right around the corner. This time of year brings many opportunities to spend time with friends and family, and gives you many opportunities to take great photos. If you tend to hide from the camera out of concern for the appearance of your smile, Dr. Michael Lee and the team at Cincinnati Center for Corrective Jaw Surgery can help. Dental implants are an ideal solution for missing teeth and will get your smile in picture-perfect shape in time for the holidays.

Dental Implants
For a long time, traditional dentures and bridgework were the only solutions for missing teeth. While these treatments still help many people, dental implants are quickly becoming the standard form of care. Implants are set apart as a superior treatment option because they:

• Offer a permanent tooth loss solution
• Are firmly anchored in the mouth and will not move
• Allow you to confidently bite and chew all kinds of food
• Are carefully colored to match neighboring teeth for a more natural appearance
• Special care beyond regular dental checkups and at-home hygiene is not required
• Special cleaners are not required

There are many reasons why people choose implants. Look forward to enjoying the holiday feasts and smiling confidently for holiday photos with this innovative approach to dental care.

Dr. Lee now provides a New Option for Conservative Surgical Management of the Problematic TMJ

Dr. Lee Now Provides a New Option for Conservative Management of the Problematic TMJ

We are pleased to announce that the Cincinnati Center for Corrective Jaw Surgery is now able to care for patients who suffer from jaw joint problems commonly known as TMJ or TMD with arthroscopic surgery.

What is TMJ & TMD?

TMJ stands for temporomandibular joint – the jaw joint. TMD stands for temporomandibular dysfunction. TMD relates to pain, limited opening, bite problems from muscle overloading and conditions that range from clicking, popping and locking of the jaws to rheumatoid arthritis. It’s hard to believe a joint so small with so little in it (the TMJ holds less than a teaspoonful of fluid) could cause so much pain and misery for so many people.

Arthroscopic Surgery
While arthroscopic surgery of large joints like the knee and shoulder is standard fare and widely available, arthroscopic surgery on smaller joints like the TMJ is less common. Like other joints, these symptoms described above can be decreased by cleaning out inflammation in the joint and placing medications in it – to lubricate it and decrease inflammation in the lining of the joint space. But unlike other joints, accomplishing this feat has been problematic for two reasons. 1) the potential complications with middle ear and surrounding nerves to the face and 2) the relative size of the joint to the size of the arthroscope going into it. Fortunately, these problems have been eliminated or greatly reduced with the introduction of the McCain technique and the McCain arthroscope.

The McCain technique and the McCain arthroscope
In the winter of 2016 and the spring of 2017, I was trained by Dr. Joseph McCain, broadly recognized as one of the founding fathers of TMJ arthroscopy, on the McCain technique using the McCain arthroscope. This spring, I introduced this special technique and tool to the Cincinnati Region.

Dr. McCain has been involved in the design of the arthroscope since 1990. It has the most sophisticated optics available in small joint arthroscopy and provides excellent images given its micro size of 1.8 millimeters, just over one 16th of an inch.

The McCain Technique is minimally invasive. The procedure is quick and very effective with a success rate of 90%. More importantly, it is safer than previously described arthroscopy techniques. Also, the small diameter of the scope allows for more instrumentation of the joint and more mobility of the scope in the joint space.

Our treatment algorithm

According to the American Association of Oral and Maxillofacial Surgeons, 35 million people in this country suffer from varying degrees of TMJ dysfunction or TMD. Approximately 10% of this group will seek treatment for their symptoms. The majority of those patients can be well managed with conservative therapy – therapy that can be initiated by, and managed by, family dentists.

Our treatment algorithm begins with the dentist:
A. Prior to our consultation with the patient, we ask that the dentist fabricate an occlusal guard for the patient and begin conservative treatment of the muscle or joint
B. If the dentist is comfortable managing the patient’s pain through the use of selective anti-inflammatory medications, we request that it be added to the regime, if possible.
C. Additional medications can be given to the patient to decrease grinding and clenching

Most patients will be effectively managed at this point, but those who continue to have pain usually suffer from:
1. The lateral capsule of the TMJ is painful to the touch (is this a correct rewording?)
2. Painful clicking, grating or popping of the joint
3. Painful and limited opening or lateral movements of the lower jaw

When a patient falls into the category above, we request that they be referred to our office for further evaluation and possible treatment. At their initial appointment, Dr. Lee and his staff will evaluate them and obtain a history of their conservative treatment and their response to it. Traditionally, we will add or adjust pharmaceuticals and initiate aggressive physical therapy. From a diagnostic standpoint, we will obtain a CBCT to evaluate the joints and, based upon our findings, consider an MRI to determine meniscus position and status.

After further diagnostic imaging and more aggressive conservative treatment, we will see the patient back in our office to discuss the most minimally-invasive therapy that can be employed – a diagnostic arthroscopic procedure. Successful treatment of cases that have been properly selected and well-managed with conservative therapy nears 90%.

Summary
To be sure, arthroscopic surgery of the TMJ is to be reserved for cases of TMD that are not resolved with conservative treatment. Proper vetting of the patient and strict adherence to accepted conservative management principles is key.

Four Ways Exparel, a Long-Lasting, Non-Opioid Pharmaceutical, Can Make Your Oral Surgery Recovery Easier

Four Ways Exparel, a Long-Lasting, Non-Opioid Pharmaceutical, Can Make Your Oral Surgery Recovery Easier

At the Cincinnati Center for Corrective Jaw Surgery, our focus is your recovery. That is why we are proud to offer Exparel (bupivacaine), a long-lasting, non-opioid pharmaceutical, at our practice.

Exparel could ease your recovery from your upcoming oral surgery, and in fact, if you’ve been putting off oral surgery such as getting your wisdom teeth removed, you might finally feel ready after learning about this new drug. While you are asleep, Exparel is injected throughout the surgery site and provides local anesthesia that can last 24 hours and sometimes up to two days.

Here are some of the ways Exparel help you through your postoperative period:

1. There’s no need to worry that pain will set in before the pain pills begin to work. When you first arrive home from oral surgery, there’s no need to time that first dose of pain medication just right, so you don’t experience pain before the Novocaine wears off. Plus, when you’re recovering, you may be tired and need plenty of rest. You will not need to set the alarm clock to take pain medication. There is no risk of losing track of when you took your last pain reliever and when it’s time for the next one. For an extended period of time following your procedure, Exparel will do its work, so that you don’t even need to think about pain medication.

2. It limits your chances of getting hooked on opioids. Opioids receive a lot of attention for their potentially addictive nature. This can even be a concern for someone taking Vicodin or Percocet for just a few days. And, opioids can cause other unpleasant side effects like nausea, vomiting and constipation; some people simply do not tolerate these medications well. Many people simply wish to avoid narcotics if possible. Exparel can reduce the number of narcotic pills you or your family member need to take.

3. You can stay more alert during your recovery. On narcotic drugs, patients often feel sleepy, dizzy, and unfocused – not the best for your son or daughter who needs to get back to studying for school. Following surgery, you may wish to take it easy, but your busy life may still get in the way and make that hard. You may have children depending on you or you may need to drive. Exparel minimizes your post-operative pain and may make your discomfort amenable to over the counter pain medications.

4. You can trust a drug that doctors have long used. Exparel contains bupivacaine, which doctors have relied on for pain relief at surgical sites since the 1950s. Exparel is formulated differently than bupivicaine to work slowly over a much longer period of time. So have peace of mind knowing that scientific innovation has updated an already well-established option. Exparel itself is well-tested and has been widely used since 2012.

No one enjoys recovering from surgery, but we want to help you make it as smooth and painless as possible. We would welcome the opportunity to talk with you about your individual situation and how Exparel, and our innovative Cool Comfort Wrap, can ease your pain in recovery. Call or email us for an appointment now.

Case Study: Skeletal Deformities Involving the Maxillofacial Skeletal Complex

Skeletal Deformities Involving the Maxillofacial Skeletal Complex

This month’s case report demonstrates the team approach we use to treat more complicated skeletal deformities involving the maxillofacial skeletal complex.    These types of skeletal problems commonly include deformities of the nose and the bones surrounding the orbits.  They are still growth deformities however and should not be confused with congenital deformities of the maxillofacial complex such as Pierre-Robin Syndrome and Treacher Collins Syndrome. 

Acquired skeletal deformities that are hypoplastic/hyperplastic in nature are commonly treated in private practice but the treatment of these acquired skeletal problems with orbital reconstruction and nasal reconstruction is not.  Very few orthognathic surgeons outside of academic settings can offer this valuable service to their patients.  A team approach is a must.  Having the right combination of a facial plastic surgeon and an oral and maxillofacial surgeon is not enough, however.  The magic ingredient?  A well trained operating room and anesthesia staff.

Performing nasal surgery and jaw surgery is a great benefit for the patient.  It saves the patient a separate surgery, anesthetic and hospital bill, not to mention the second period of recovery.  But doing them together requires a hospital-based anesthesiology department and operating room staff skilled at converting nasally intubated patients to orally intubated patients in the middle of a long, complex reconstructive surgical procedure involving the entire airway. 

The case presented this month is commonly performed at Mercy Hospital- Anderson and is not possible without the skill and expertise of the operating room staff and anesthesiologists.  

The patient in figure 1 is typical of individuals who present with skeletal deformities of the nose, midface and mandible.  From a frontal and lateral view, the sunken in look to the orbital bones and upper jaw are easily recognizable.  The nose appears large because it is long and narrow but also because it is projecting from a hypoplastic midface. The mandible appears narrow and prognathic, but in reality is not significantly enlarged, at least not horizontally. It is more so vertically.   The most common mistake made in cases such as these is for the surgical team to focus on the strong looking mandible and treatment plan the patient for an extensive mandibular setback procedure.  This is a disaster on many fronts – both aesthetically and more importantly from an airway standpoint.  Sleep-disordered breathing is certainly to follow!

There is always overwhelming dental compensation in these cases and the orthodontist must pay special attention to positioning the upper and lower incisors to obtain perfect incisor inclination before surgery.  Without proper placement of the incisors, overbite and overjet will be compromised and uncoupling of incisors can occur post-operatively.  Figure 2 shows the presurgical setup of a similar case where improper incisor set up limited overjet and overbite.  

Compare this to the presurgical setup in our case, figure 3 and side by side models of the two cases, figure 4.

Fig. 3

Fig. 4

From figure 1, the hypoplastic look to the upper jaw, orbital bones and zygomatic arches is easily recognizable.  These areas will look even more sunken in if the maxilla alone is advanced.  Infraorbital rim/zygomatic bone augmentation is needed to obtain good aesthetics.  This graft is very simple to do once the infraorbital rim and the lateral aspect of the arch is dissected out of the overlying soft tissue and a pocket is developed next to the bone to accept the graft.  The graft is a combination of nonresorbable hydroxyapatite, collagen and water. They can be molded into soft wafers the size of miniature Hershey chocolate bars and placed under a heat lamp. (Figure 5) 

 After several hours of drying they can be slipped into place and positioned to obtain symmetry and projection of the infraorbital rim region.  (Figure 6)  

Maxillary hypoplasia accentuates the complexity of any nasal deformity.  In our case, the nose appears elongated with a slightly downturned nasal tip.  It overwhelms the face.  Softening the dorsum of the nose and advancing the maxilla greatly improved the patient’s aesthetics. (Figure 7)

The patient’s mandibular prognathism, is accentuated by his midfacial hypoplasia. A common mistake made by the inexperienced surgeon is to focus on the prognathic mandible and aggressively set it back when, in reality, an extensive maxillary advancement is in order.  This can be facilitated by advancing the maxilla to its optimum aesthetic position using glabella vertical as a reference. (Figure 8)

Figure 9 compares the preoperative and postoperative facial result.  His preoperative and postoperative occlusion is seen in Figure 10.

Fig. 9

Fig. 10

This case demonstrates the nuances of combined orthognathic surgery and nasal reconstruction.  We thank Dr. David Quast for his referral of this most complicated case and for his orthodontic expertise in preparing him for surgery. Additionally, we thank Kevin Shumrick MD for his expertise in nasal reconstruction.

 Case Study: “C” Shaped Facial Asymmetries

Case Study: “C” Shaped Facial Asymmetries

Facial asymmetry is a relatively common maxillofacial skeletal deformity.  All patients have some degree of asymmetry, but minor discrepancies from one side to the other are not perceived by the average layperson and have no functional clinical significance.  Marked facial imbalances, however, can cause functional issues with mastication and overloading problems with the masticatory system.  While some skeletal asymmetries can be masked orthodontically, many cannot and, as interest in facial aesthetics increases, more patients are seeking orthognathic surgeons for treatment.  More orthodontists are referring patients for treatment of facial asymmetries as complaints of crooked smiles and deviated chins are voiced by their patients.  This is especially true among dental patients undergoing “smile aesthetics”.

Midface and mandibular skeletal asymmetries are complicated deformities involving all three planes of space and encompass yaw, pitch, and roll of the jaw bones.  Understanding the movement of the jaws in three planes of space is very important because success is dependent upon removing all bony interferences at the time of surgery to ensure a stable outcome. 

Cone beam CT scanning along with three-dimensional virtual surgical planning has been a game-changer in this regard.  Through these advanced technologies, orthognathic surgeons have the ability to see the midfacial and mandibular skeletal deformity clearly and from all angles.  Figure 1 shows a patient preoperatively and the extent of the skeletal facial asymmetry. 

Facial asymmetries can be categorized into four distinct groups with the simplest asymmetry being confined to the body of one side of the mandible and the most complicated asymmetries being what is termed a “C” shaped asymmetrical skeletal pattern because it involves both the upper and lower jaw.  With this type of deformity, as demonstrated in Figure 2, the condyle, mandibular body and symphysis of the mandible is affected in combination with maxillary canting and yaw. 

The patient in Figure 1 is a 22-year-old male with a facial asymmetry involving both the maxilla and mandible in a classic “C” shaped pattern.  There is a definite cant to both the midface and mandible with a severe deviation of the lower jaw to the left and a corresponding shift of the mandibular midline to the left side.  Canting of the maxilla follows the cant of the mandible with a midline shift to the left as well.

Virtual surgical treatment planning allows for a three-dimensional view of both the maxilla and mandible to better evaluate yaw of both jaws.  Evaluating and correcting this yaw has plagued orthognathic surgeons until virtual surgical treatment planning became available five years ago.  Figure 3 demonstrates the pre-surgical and post-surgical rotation of the jaws and correction of the yaw. 

In Figure 4, it is easy to see the extent of the maxillary cant after the mandible has been corrected for cant and deviation. 

Note the sagittal advancement on the left side of the mandible (Figure 5), compared to the right side that actually went backward as the asymmetry to the left was corrected and the midline of the mandible was placed on the midline of the upper jaw. 

Leveling the maxilla requires raising it on the right side almost 2mm and lowering it on the left by just as much (Figure 6).  

Advancement of the maxilla by 6mm corrected the anterior posterior position of the midface and corrected the Class III pseudoprognathism (Figure 7). 

Figures 8 and 9 compare the pre-operative and post-operative result.  Good aesthetics is accomplished along with re-establishment of normal function.  The chin is still asymmetrical as was noted in the virtual surgical planning.  A genioplasty procedure was declined by the patient.

 “C” shaped facial asymmetries are the most difficult to diagnose and treat.  Postoperatively they require close follow-up by both the orthodontist and the oral surgeon because shifting can occur from muscle function and the complexity of the skeletal move.  Three-dimensional virtual surgical planning has lessened relapse dramatically by exposing bony interferences that prevent passive movements of the mandibular segments.  This can be seen in a close-up of the left sagittal split osteotomy site.  Virtual surgical treatment planning identifies these interferences so they can be removed at the time of surgery.  (Figure 10)

I thank orthodontist, Jay Parekh, DDS, for referring this most-complicated case and having confidence in our ability to diagnose and treat complex deformities of the midface and mandible. 

Case Study: Orthognathic Surgery for Maxillary Hypoplasia + Compromised Orthodontic Treatment

Case Study No. 2: Orthognathic Surgery for Maxillary Hypoplasia + Compromised Orthodontic Treatment

A complication of orthodontic treatment sometimes arises when anterior maxillary tooth position is compromised in an attempt to camouflage the need for Orthognathic Surgery. This scenario has become more and more common in the last few decades as orthodontists try to forgo the incorporation of Orthognathic Surgery in patients with combined dental and skeletal malocclusions.

Patients sometimes struggle to accept treatment plans that include jaw surgery. They reject treatment altogether when they can’t find simple answers to their questions about medical insurance coverage and cost of Orthognathic Surgery. Many times the orthodontist becomes frustrated when they become mired in a case they can’t finish because a skeletal deformity stands in their way. Camouflaging the misaligned jaw, compromising the final position of the teeth or compromising the final bite sometimes seems the only way out. Sometimes this strategy is “successful”. Mild mandibular asymmetries can be hidden, a minimally hypoplastic maxilla can be covered up by proclination of maxillary incisors, and mandibular retrognathia can be concealed by flaring mandibular incisors. While these compromises may not lead to immediate functional or stability problems, over the course of years or decades serious issues may arise. Such is this case.

The patient is a 48-year-old female who, as a young adult, underwent orthodontic treatment to resolve maxillary crowding and a palatally impacted canine. (Fig. 1)

No treatment was suggested for her skeletal mid-facial hypoplasia. After several years and several attempts at moving the right canine into position, it was lost and a particulate graft was done to prepare the site for an implant. The first fixture that was placed failed. The second implant successfully integrated but was positioned so apically to the adjacent teeth that it could not be restored. (Fig. 2) 

Complicating the situation, the patient began experiencing mobility in her anterior teeth. Her workup confirmed maxillary hypoplasia and her compromised orthodontic treatment, consisting of proclination of the maxillary incisors, canines and bicuspidsto obtain overjet, resulted in tooth mobility, and root resorption of # 7. (Fig. 3) 

Another orthodontic consult was obtained and, through a team approach, a treatment plan was formulated to correct the position of the anterior maxillary teeth and replace the missing right canine.

Our first step was to agree that the malocclusion would require Orthognathic Surgery. The workup by the orthodontist using a Sassouni analysis was confirmed with a G. William Arnett analysis and a work up using Andrew’s “Six Elements of Orofacial Harmony”. A multi-segmental LeFort I advancement was determined to be the best surgical procedure to return the anterior maxillary dentition to its proper position to the skeletal base.

Two hurdles had to be overcome:
1. Removing the implant and reconstructing the area with an autogenous bone graft so that an implant could be placed after the orthognathic surgery.
2. Obtaining space to allow for clockwise rotation of the premaxilla and repositioning of the anterior segment for the advancement of the entire maxilla to a Class I canine relationship.

Prior to orthodontics, the implant in the area of # 6 was removed and the area bone grafted using an enbloc bone grafting technique overlaying a particulate graft to fill the defect from the removal of the implant. A CBCT confirmed the success of the bone graft. (Fig. 4)

 

Progress model surgery confirmed the premaxilla could be rotated clockwise by extracting the maxillary 1st bicuspids and using the extraction spaces to pivot the premaxilla clockwise and rotate it down. The posterior segment was split and widened to correct the Curve and Wilson. (Fig. 5)

The posterior maxillary segments were then advanced to a Class I canine relationship and the extraction spaces closed. (Fig. 6)

A postoperativecephalometric x-ray confirmed the clockwise rotation of the anterior maxillary segment by 15 degrees. (Fig. 7) The patient is awaiting the placement of the titanium fixture in the area of # 6.

This case demonstrates the problem of tooth mobility and bone loss when anterior teeth are proclined and placed into functional occlusion. Flaring the teeth outside the limits of their skeletal base to camouflage a Class III or Pseudo-Class III skeletal relationship is sometimes a recipe for severe dental consequences. Treatment through a combined orthodontic and Orthognathic Surgical approach can be the solution. A pre-operative and post-operative smiling image demonstrates the aesthetic difference when anterior maxillary teeth are placed in their proper axial inclination. (Fig. 8)

 

Dental Implants 101


What is a Dental Implant?
A Dental implant is a titanium post surgically threaded into the jawbone beneath the gums. It has four parts: threaded post, crown substructure, ceramic crown and a screw to attach it to the substructure and threaded post in the bone. Dental implants may replace a single tooth or multiple teeth. Dental implants are the ideal tooth replacement solution because they actually mimic the roots, appearance and feel of a natural tooth.

What are the advantages of a Dental Implant?

• Improved aesthetics: Dental implants look more natural than other prosthetics (bridge or denture). It mimics the natural appearance of a tooth.
• Improved speech: Many people wearing dentures have difficulty when speaking because dentures can slip and get dislodged.
• Better chewing power: Slipping dentures make it hard to chew food properly as they are very unstable.
• Convenience: Dental implants don’t need to be removed to clean, unlike dentures.
• Durability: Dental implants, when taken care properly, last much longer than a bridge. Bridges fail over 40% of the time within 10 years of placement. And when they fail, the patients lose another tooth. Implants can last 20 – 25 years.

Who can have Dental Implants?
The simple answer is almost everyone is a candidate for some type of dental implant to help restore chewing function. Start by discussing your options with your dentist or by calling Dr. Lee’s office for a consultation.

After your consult, Dr. Lee and your dentist will develop the best dental implant treatment plan for you. You will need to visit the dentist two to three times a year for dental implant cleaning. Good dental home care routine should also be practiced. Dental implants are like your own teeth and require the same care. Keep your implants plaque-free by brushing and flossing.

Dr. Lee Further Establishes Himself as One of the Region’s Experts in Dental Implants

Dr. Lee attended a unique course on the latest innovation in dental implant surgery.

Advances in dental implant surgery continue to make the replacement of teeth easier, less time consuming and more affordable.  The latest innovation comes from Straumann Implant Systems and allows the immediate placement of dental implants in almost every situation. 

Called the Ring Graft, the technique consists of the placement of a bone graft in the shape of a donut that is prepared to accept an implant in the hole.  Placed together on the site of an extracted tooth, it affords needed stability so that the implant will be incorporated into the healing bone of the extraction site. 

Dr Lee (pictured in the middle of the second row) attended the second cadaver course in the country designed by Straumann Dental to certify dental surgeons in the new bone grafting/implant placement technique. This technique is now being performed by Dr. Lee.  Additional information will be available on Dr. Lee’s website, soon but Dr. Lee is scheduling patients for evaluation for the new procedure now at his office.  Please call 513-232-8989or visit us on our website, cincinnatijawsurgery.com
