Validity of Computed Guided Technology in Proper Placement of Intermaxillary Fixation Screws in Mandibular Fractures

Fractures of the facial skeleton involving the teeth bearing segments can lead to disruption of the dental occlusion, and difficulties with speech and mastication. The temporary fixation of opposing jaws is called maxillomandibular fixation and is usually secured through placement of IMF screws and wires. The correct placement of IMF screws can be challenging. Such planning may make use of radiographs and computed tomography scans. Knowledge of safe zones in the facial skeleton for screw placement through the use of pre-operative 3-dimensional planning may prevent some of the cited complications. The use of a custom made surgical guide for IMF screw placement has the potential to reduce operation time, optimize screw position, and minimize injury to dental roots and important anatomical structures. Aim: The aim of this study is to Assess the use of computed guided technique in the proper placement of IMF screws in mandibular fractures. Materials and Methods: This clinical study will be conducted on 20 patients who will be equally and randomly distributed into 2 groups: Group A: 10 patients will be treated with 3D guided placement of IMF screw. Group B: 10 patients will be treated with Conventional placement of IMF screws. To assess the accuracy of IMF screws placement in each group.
