2007 Annual Session - Airway Implications Of Resting Tongue Posture In Adult Patients

Credits: None available.

Dr. Lowe is professor and chair of the Division of Orthodontics in the Faculty of Dentistry at The University of British Columbia and maintains an orthodontic practice in Vancouver, Canada.

Recently, the importance of resting tongue posture in the adult population has received a great deal of attention as it directly affects snoring, upper airway resistance syndrome and obstructive sleep apnea. Orthodontists, with their knowledge and training of functional appliances and established skills to evaluate jaw position, are ideally suited to provide oral appliance therapy in this field. Sleep disordered breathing patients are excellent adherents to therapy after only a few nights of uninterrupted sleep and the subsequent restoration of adequate REM sleep. Oral appliances have a direct effect on tongue posture during sleep and help to stabilize the mandible in a closed vertical position. They also have a direct effect on genioglossus muscle activity. However, a reduction in overbite and/or the development of open bites with long-term wear of oral appliances in adult patients have recently been identified. These long-term occlusal changes are predominantly dental in nature and typically occur after more than two or three years of nightly wear. A better response to appliance therapy is seen in those post titration subjects who exhibit a more anterior velopharyngeal wall, a larger radius of curvature of the airway and an increase in velopharyngeal size. Because sleep apnea is a progressive life-threatening disease and patients tend to be very compliant over time, the long-term occlusal changes may continue each decade.

Learning Objectives:

• Learn about the short and long term side effects of oral appliance wear in subjects with sleep disordered breathing
• Evaluate Occlusal and cephalometric changes as a consequence of oral appliance wear
• Appreciate the importance of skeletal subtype before treatment when predicting potential long term side effects

2007 - AAO Interdisciplinary Conference - Pre-restorative Orthodontics in the Anterior Esthetic Case: When to Restore and When to Align

Credits: None available.

Pre-restorative Orthodontics in the Anterior Esthetic Case: When to Restore and When to Align

Interdisciplinary dentistry is proving to be the most effective means by which we can deliver the highest level of service to our patients. Whether addressing specific cosmetic concerns or providing advanced rehabilitation and restoration through coordinated efforts at the specialist level, we can engage in more comprehensive treatment and superior outcomes. Through carefully documented clinical cases, the presenters will emphasize communication, decision making, sequencing and execution. Areas in which the various specialists can work in concert to better serve our patients will be illustrated. The forum will provide for a platform upon which we can all begin to communicate and explore some of the latest developments, many of which are very exciting. Participants should come prepared to expand their thinking and horizons.

Learning Objectives:

• To gain an appreciation for some of the decisions involved in interdisciplinary treatment from the perspective of each specialist
• Understand the sequencing of interdisciplinary case flow
• Understand the periodontal benefits of tooth position
• Understand the periodontal management of orthodontic patients
• Understand the implementation of adjunctive orthodontic modalities for prosthetic benefit
• To gain an understanding of how orthodontics can interact with implants

2007 - AAO Interdisciplinary Conference - Maxillary Posterior Osteotomies to Maximize Esthetic or Restorative Results

Credits: None available.

Although the potential adverse soft-tissue affects of the LeFort I osteotomy have been described and surgical procedures have been developed to minimize the impact of these changes, patients can still end up with unesthetic results following surgery. To minimize the likelihood of these adverse soft-tissue changes, treatment planning decisions should be made jointly between the orthodontist and surgeon. Of primary importance is the position and angulation of the maxillary incisors, as this will contribute greatly to midface esthetics and often lower face esthetics as well. Management of individuals with anterior open bit, occlusal plane deviations or upright maxillary incisors without crowding will be reviewed with special emphasis on patients with previous maxillary premolar extractions and subsequent unesthetic flattening of the upper lip. The orthodontist and surgeon should be aware of the soft-tissue impact of various LeFort I procedures and how to either avoid or utilize these changes to maximize the patients esthetic outcome.

Learning Objectives:

• The orthodontist and surgeon will understand their individual role in providing patients undergoing LeFort I surgery with good midface esthetics
• Appreciate the importance of both incisor position and angulation in preparation for surgery
• Understand the soft-tissue impact of various LeFort I procedures and how to avoid or utilize these changes to maximize the patients esthetic outcome

2007 - AAO Interdisciplinary Conference - Lessons from the Outback: Integrating Implants, Orthodontics, and Comprehensive Restorative Dentistry in Small Town Rural America

Credits: None available.

Over the last few decades, doctors have become aware of the special issues associated with interdisciplinary dentistry. All of the speakers at this Interdisciplinary Conference have contributed significantly to this awareness and have provided a vision of what a team can accomplish. The main objective of this presentation will be to provide the strategies that Team Montrose uses to execute the interdisciplinary treatment plans. The strategies include a common language for communication, the mechanics of a team meeting and addressing the most common pitfalls associated with multidisciplinary teams. Treated cases will be shown to demonstrate the results.

Learning Objectives:

• To provide specific strategies for communication through a common language that allows all team members to communicate effectively during treatment planning and treatment
• To provide mechanics needed to effectively sustain an interdisciplinary team and produce quality treatment results
• To address specific pitfalls associated with interdisciplinary teams and to encourage and promote the interdisciplinary team concept

2007 - AAO Interdisciplinary Conference - Interdisciplinary Management of Missing Maxillary Incisors: Space Closure, Autotransplantation, or Implant

Credits: None available.

This lecture will deal with the advantages and disadvantages of different treatment options for replacement of missing maxillary central and/or lateral incisors in young and adult/elderly patients. The short- and long-term appearance associated with the following treatment options will be covered:

• orthodontic space closure - combination of carefully detailed orthodontic treatment and techniques from esthetic dentistry (restoration with porcelain laminate veneers and hybrid composites)
• autotransplantation of developing premolars (restoration of the abnormal crowns with porcelain veneer crowns)
• single tooth implants (restoration with porcelain crowns)

Particular emphasis will be given to the following: (1) esthetic outcome, (2) practicality and safety, (3) evidence base, and (4) long-term results for each of the alternative solutions. Learning objectives: Appreciate the advantages and disadvantages for the different treatment options to replace missing maxillary central incisors; appreciate the advantages and disadvantages for the different treatment options to replace missing maxillary lateral incisors; learn about the advantages of ultrathin porcelain laminate veneers compared with conventional porcelain fused to gold or all-ceramic crowns; learn about the long-term outcomes when teeth are replaced in young adult patients.

Learning Objectives:

• Appreciate the advantages and disadvantages for the different treatment options to replace missing maxillary central incisors
• Appreciate the advantages and disadvantages for the different treatment options to replace missing maxillary lateral incisors
• Learn about the advantages of ultrathin porcelain laminate veneers compared with conventional porcelain fused to gold or all ceramic crowns
