Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Initial records (radiographs, study casts and clinical photographs) were taken for all subjects. The same records were taken post treatment for treated subjects only. The Pre- and post- treatment VGD and lip length in static and dynamic positions and the amount of upper teeth retractions were recorded.
The paired t-test and ANOVA test were used to detect treatment changes and differences between studied groups, respectively. Factors affecting VGD were investigated using backward stepwise linear regression analysis.
