Development of a Prediction Model for Short-Term Success of Functional Treatment of Class II Malocclusion
Abstract
:1. Introduction
2. Materials and Methods
Statistical Analysis
3. Results
4. Discussion
5. Conclusions
- -
- Pretreatment of the Co–Go–Me angle was found to be the only significant predictor for the amount of advancement of the chin during twin-block therapy.
- -
- A greater advancement of the soft-tissue chin on the profile is expected with smaller pretreatment values of the Co–Go–Me angle.
