Sendai Surgery First: Biomechanics in Post-surgical Orthodontics

Current Surgery First (SF) approaches can be classified into two rather different styles. One is the orthodontics driven style. In this style, skeletal problems are solved by surgery, and dental problems are fixed orthodontically. The other is the surgery driven style. In this approach, the aim is to solve both skeletal and dental problems by surgery as much as possible. The concept of SF that we practice is the orthodontics driven style. This approach was made possible by the application of TADs (miniplates and miniscrews) which enables predictable control of the entire dentition. With TADs in combination with multi-bracketed system, the extent of surgical intervention is significantly reduced, and complex orthodontic problems in post-surgical orthodontics can be successfully solved. In this presentation, the various biomechanics which applied to post-surgical orthodontics in Sendai SF will be discussed.
