There are many different methods of mandibular fixation such as using intra osseous wiring combined with inter maxillary fixation (IMF) which showed significant amount of relapse and patient dissatisfaction, this is called nonrigid fixation. Another type of mandibular fixation is the three point fixation using positioning screws called rigid fixation. Rigid internal fixation was introduced in 1976 by Spiessel to promote healing, restore early function, and decrease relapse. The introduction of an internal rigid fixation method, instead of 5-6 week intermaxillary fixation, had the added benefit of shorter periods of hospital stay and patient convenience.' Minimal or no immobilization of the jaws allows patients to function sooner, resume their daily activities, and return to work earlier. In a relatively short period of time, the use of rigid fixation of bony segments in orthognathic surgery had become a standard of care.
