AS17B50C - 2D and 3D Virtual Planning of Complex Orthognathic Surgical Cases

‐ Apr 25, 2017 9:55am

Carefully planned and executed orthognathic surgeries can achieve remarkable improvements in the occlusion and esthetics of patients with severe skeletal deformities and dysfunctional occlusion. Orthodontists are involved in all aspects of the clinical management of such patients, including initial case analysis, presurgical orthodontics, surgical planning with a surgeon and postsurgical orthodontics. Within this process, presurgical orthodontics is the most critical step that dictates treatment outcomes. Well-designed pre-surgical orthodontic set-up requires understanding of the nature of the problems/deformities, the types of jawbone movements required for the case and surgical limitations for these movements. This lecture will describe step-by-step orthodontic management of surgical cases with severe skeletal deformities and demonstrate how to utilize 2D and 3D virtual surgical planning tools in the design of pre-surgical orthodontic set-up.

Learning Objectives:

  • Describe how to utilize 2D- and 3D-virtual surgical planning tools in the design of presurgical orthodontic set-up for patients with severe skeletal deformities.
  • Recognize surgical limitations of certain jaw bone movements for these patients.
  • Outline step-by-step pre- and post-surgical orthodontic management for the severe orthognathic cases.
