Biomechanics of Orthodontic Treatment with Dr. Vishnu Raj


Part A. Esthetic and Functional Goals during Orthodontic Finishing

Identifying and pursuing appropriate treatment objectives is a very important step and one that determines the quality of the outcome. This lecture will go over several aspects of Orthodontic Finishing with a special emphasis on optimal and evidence-based goals. The importance of facial balance, incisor position and inclination, transverse coordination, anterior and posterior occlusal relationships, as well as how to attain these objectives, will be discussed. A description of Biomechanical Strategies and Troubleshooting will be provided with some specific case examples

Part B. Alveolar Boundary Conditions- Diagnosis and Management

The envelope of tooth movement is determined by finite osseous anatomic limits, and alveolar dimensions play a significant role in establishing the direction and magnitude of tooth movement. The first half of this lecture will present the evidence on typical alveolar dimensions, diagnostic considerations, 2D vs. 3D imaging and the effect of tooth movement on the surrounding bone. The latter half of the lecture will go over the management of Critical Boundary Conditions with several examples including some mid-treatment clinical challenges.

Part C. Minimal Anchorage Mechanics – Indications and Application

Anchorage is a very important consideration in orthodontic treatment and Type C or minimal anchorage mechanics can be challenging to execute. This lecture will help clearly define and identify situations that call for minimal anchorage. A section will be devoted to the discussion of Posterior Crowding and how to identify it. Biological and mechanical considerations will be outlined with specific clinical tips on anterior anchorage preparation. A selection of cases will be presented, illustrating the clinical application of minimal anchorage mechanics.
