Specific Screw Holes Locating Surgical Guide and Pre-bent Plates

Mandibular Fractures

class III

The aim of the current study was to evaluate the accuracy of computer-guided mandibular fracture reduction versus the classical work flow

Research question: Does the use of screw holes locating surgical guide & pre-bent plates osteosynthesis accurately reduce class III mandibular fractures regarding segments integrity and occlusion more than the classical reduction and fixation? Statement of the problem: Mandibular fractures are the most frequently occurring fractures within the maxillofacial injuries. The evaluation, diagnosis, and management of these fractures remain challenging despite improved imaging technology and fixation techniques. Depending on the type and location of the fractures, various open and closed surgical reduction techniques can be utilized. There are several critical and inherent limitations to the current ,standard approach of mandibular fracture reduction and fixation includes : (improper alignment of segments ,malocclusion ,nerve affections and related teeth roots injury). There is a possibility to overcome these limitations with the help of computer-guided surgery . The introduction of CAD/CAM software has provided surgeons with an opportunity to perform virtual manipulations of CT datasets preoperatively and production of corrected mandibular model for plate pre-bending and fabrication of plate locating surgical guide which provide accurate segment reduction and fixation with accurate post-operative occlusion and minimal post-operative complication . The aim of the current study was to evaluate the accuracy of computer-guided mandibular fracture reduction versus the conventional work flow Rationale for conducting the research: Through computer guided mandibular fracture reduction investigators can provide proper segment alignment with subsequent accurate post-operative occlusion in addition reduce intra-operative time , post-operative pain and edema
