About

the aim of the study is to establish reference data that could be used for the creation of more accurate three dimensional prediction of soft tissue outcome.

Full description

in this study, 15 skeletal class 2 orthognathic patients will be selected. CBCT and proface will be done preoperatively. after the surgery and 6 months later the imaging investigations will be repeated to investigate the soft tissue changes that have resulted due to the bone movement.

Enrollment: 15 estimated patients

Sex: All

Ages: 18 to 40 years old

Volunteers: No Healthy Volunteers
