In this research the investigators aim to minimize the use of more hardware in the fixation of the orthognathic surgery cases. The objective of this study is to assess the accuracy of the plan transfer with two customized titanium plates versus four customized titanium plates.
In orthognathic surgery cases, maxillary repositioning in three dimensions can be obtained. Recently using the custom-made plates instead of wafer used in classic models can get an accurate plan transfer, however it can get suboptimal accurate repositioning. The aim of the study is to evaluate the accuracy of two customized titanium plates versus four customized titanium plates in transferring the virtual plan in orthognathic surgeries.

Specific measurement variable: The skull base in the virtual surgical plan was superimposed using point-based matching ICP registration using anatomical reference points, followed by manual surface-based registration to surface best fit with the skull base in the actual post-operative CBCT scans.

A self-administered OQLQ translated into Arabic will be used to assess quality of life at the recruitment visit and six months after the surgery. Questions 1, 7, 10, 11, and 14 will be about facial aesthetics and appearance, questions 2 to 6 will be about oral function, questions 8, 9, 12, and 13 will be about the awareness of the deformity, and questions 15 to 22 will about the social aspect of the deformity. The questionnaire contains 22 questions, and each question has score from 1 to 4, so each patient will have a score from 22 to 88.
Time frame: 6 months
