Overview

This study aims to evaluate the accuracy of "Dolphin 3D" software for prediction of soft tissue changes in management of patients seeking orthognathic surgery to treat their mandibular deformities and collecting their feedback regarding aesthetic satisfaction.

Outcomes

Primary Outcomes

The soft tissue prediction Accuracy

A comparison between the virtually planned mandibular movement and postoperative 3D photo All patients had to have both preoperative (Tpre) and at least 6 m postoperative (Tpost) CBCTs . All CBCT images were acquired with a Scanner as a part of the initial diagnostic records . Tpre and Tpost CBCT scans were imported to Dolphin 3D software. Three-dimensional voxel-based superimposition on the cranial base was performed between Tpre and Tpost for each patient, to accurately measure the skeletal movements performed during the surgery. A virtual orthognathic surgery (Tsim) was performed on T0 image to mimic the actual skeletal movements using the virtual surgical planning tool in Dolphin 3D .The differences between TSim and T1for the patients were measured

Time frame: Day 0, and after 6 months
