Assessment of Maxillary Stability in Bimaxillary Orthognathic Patients Using the Inverted Sequence Approach
Study Details
Study Description
Brief Summary
The investigator will assess the inverted sequence approach in the treatment of class III patient undergoing bimaxillary orthognathic surgery

N/A |
Detailed Description
The investigator will compare the maxillary stability in class III orthognathic patients undergoing bimaxillary surgery by two surgical approaches ; the mandible-first (intervention) and the maxilla-first (control)

Outcome Measures
Primary Outcome Measures
- the change in maxilla stability [6 months]
to assess the change in maxillary stability on cone beam CT obtained immediately and 6 month postoperative. the measuring unit is millimeter
Secondary Outcome Measures
- Patient satisfaction [6 month]
"the quality of life questionnaire" describes the patient's satisfaction during the entire treatment period which is done through a questionnaire answered by the patient through a score between 0-10 the measuring unit is numerical
