Edward H. Angle Award Lecture presented by the Lifetime Achievement Award Recipient - 30 Years of Achievements: Our Proudest Moments

Initially, the research efforts focused on growth, showing that it was possible to mathematically model and predict the craniofacial changes that occur. It soon became clear that relative, rather than absolute, growth was key for understanding structures’ response potentials. The focus then shifted to masticatory function and jaw kinematics, demonstrating the detrimental effects of malocclusion and the importance of neurosensory adaptation. Our work related to long-term post-treatment stability showed that orthodontic treatment is not inherently unstable; we now know what causes instability. We then went on to prove that miniscrews can cause damage and that their design can be optimized. Efforts then shifted toward accelerating tooth movements, demonstrating what works and why it works. More recently, we have focused on the diagnosis and treatment hyperdivergent retrognathic Class II's, demonstrating that it is possible to produce significant long-lasting orthopedic changes.

Learning Objectives:

• Recognize that orthopedic treatments must be based on our understanding of craniofacial growth.
• Demonstrate how occlusion influences masticatory function.
• Understand why the effects of surgically accelerated tooth movements are limited in limited in terms of duration and scope.
