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.
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.

3D soft-tissue changes (linear)
the changes that have occurred in the soft tissue of the face after undergoing orthognathic surgery
Time frame: 6 months
Proportion of soft tissue change to hard tissue change
the distance that the soft tissue has moved compared to the underlying bone, as a percentage.
Time frame: 6 months
Is the esthetic outcome as expected/imagined?
using a 100mm visual analogue scale the patient will be asked to score how the aesthetic outcome measured against his expectations. 0mm is the worst score where the changes havent met the expectations at all and 100mm is where the outcome has perfectly met the expectation.
Time frame: 6 months
3D soft-tissue changes (angular)
the changes that have occurred in the soft tissue of the face after undergoing orthognathic surgery
Time frame: 6 months
3D soft-tissue changes (volumetric)
the changes that have occurred in the soft tissue of the face after undergoing orthognathic surgery
Time frame: 6 months
