Summary
The surgery-first approach prioritizes facial aesthetics before occlusion, shortening treatment duration. This method involves orthognathic surgery before orthodontic treatment, offering faster results for patients.
Area of Science:
- Dentistry
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- The conventional orthodontics-first approach treats occlusion before facial aesthetics.
- The surgery-first approach reverses this sequence, prioritizing facial improvements.
Purpose of the Study:
- Introduce the surgery-first approach in orthognathic surgery.
- Provide guidelines for orthodontic management and model surgery without presurgical decompensation.
Main Methods:
- Osteotomy is used to address skeletal issues and dental compensation.
- A transitional occlusion is established post-surgery.
- Postoperative orthodontics refines the occlusion.
Main Results:
- Facial aesthetics and patient chief complaints are addressed early.
- Treatment duration is reduced to 1-1.5 years.
- Accelerated orthodontic tooth movement is observed post-surgery.
Conclusions:
- The surgery-first approach offers significant advantages in patient satisfaction and treatment efficiency.
- It effectively manages skeletal problems and dental compensation.
- Postoperative orthodontics plays a crucial adjunctive role.
