2013 Joint AAO-AAP Conference - Orthodontic Movement and Periodontal Bone Defects: Rationale, Timing and Clinical Implications / Localized Controlled Bone Injury to Enhance the Rate of Tooth Movement - CE Credits 1.5

Orthodontic Movement and Periodontal Bone Defects: Rationale, Timing and Clinical Implications

Combined orthodontic and periodontic treatment may be a reliable therapy for advanced periodontal disease.

Learning Objectives:

• To understand the biology of pathologic tooth migration in periodontal patients
• To evaluate the implications for orthodontic movement into infrabony defects
• To learn where orthodontic therapy should be placed in the treatment plan of a periodontal patient

Recently, interest has surged in orthodontic treatment adjuncts that may enhance the rate of tooth movement. Physical and pharmacological methods have been shown to modulate the speed of tooth movement both in clinical and basic research. Among the physical methods described is the localized bone injury superposed to traditional orthodontic tooth movement. This lecture will describe the different surgical methods, combined with different systems of force delivery, and the evidence behind their effectiveness.

Learning Objectives:

• Highlight the different surgical methods that have been described clinically as enhancing the rate of tooth movement
• Provide an overview of the basic science and clinical evidence regarding corticotomies as rate of tooth movement enhancers
• Describe the preliminary results of a randomized clinical trial evaluating the role of a minimal localized controlled bone injury in the rate of tooth alignment
