Summary
The Surgery First Approach (SFA) and Surgery Early (SE) offer shorter pre-surgical orthodontic treatment for dento-maxillofacial deformities. Clinical features did not significantly influence post-surgical orthodontics duration.
Area of Science:
- Orthodontics and Oral Surgery
- Dento-maxillofacial Surgery
- Orthodontic Treatment Planning
Background:
- Surgery First Approach (SFA) and Surgery Early (SE) are emerging alternatives to conventional multi-stage treatments for dento-maxillofacial deformities.
- The specific role of orthodontists and factors influencing treatment duration in SFA/SE require further investigation.
- Understanding patient characteristics is crucial for optimizing these advanced surgical-orthodontic techniques.
Purpose of the Study:
- To analyze clinical characteristics of patients undergoing SFA and SE.
- To determine if patient-specific factors influence the duration of orthodontic treatment in SFA/SE.
- To compare SFA and SE regarding treatment timelines and influencing variables.
Main Methods:
- Retrospective analysis of 191 patients with dento-facial deformities, focusing on 31 SFA and 12 SE cases (2012-2017).
- Comparison of pre-treatment data including age, PAR Index, ANB angle, and curve of Spee between SFA and SE groups.
- Regression analysis to assess the impact of clinical parameters, bracket type, and intervention type on post-surgical orthodontic duration.
Main Results:
- Patients undergoing SFA/SE had Class III, Class II, or active Unilateral Condylar Hyperplasia.
- No statistically significant pre-treatment differences in age, PAR Index, or curve of Spee were observed between groups.
- Overall therapy duration was significantly shorter with SFA/SE, primarily due to reduced pre-surgical orthodontics; post-surgical duration was not significantly different.
Conclusions:
- Surgery First/Early Approach is indicated for specific malocclusions meeting strict criteria.
- Treatment protocols and post-surgical occlusal stability are more critical in determining therapy duration than patient clinical characteristics.
- SFA/SE can effectively reduce overall treatment time, particularly pre-surgical orthodontic phases.
