Accuracy of Maxillary Two Customized 3D Titanium Miniplates Versus Four Customized 3D Miniplates

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.

Inclusion Criteria: .Patients with dentofacial disharmony and misalignment requiring orthognathic surgeries. * Patients with no signs or symptoms of active TMDs. * Highly motivated patients. Exclusion Criteria: * Patients who refused to be included in the research. * Patients with systemic diseases that may hinder the normal healing process or render the patient not fitting for general anesthesia. * Patients with intra-bony lesions or infections that may retard the osteotomy healing.
