Evaluation of the Efficay of Computer Guided Lag Screw Fixation in Comparison to Conventional Lag Screw Fixation in Anterior Mandibular Fractures. Randomized Clinical Trial (RCT)

Abstract

Background and Objective: This study aimed to compare the use of computer guided technology to place
lag screws in anterior mandibular fracture in comparison to convectional technique
Materials and Method: This study included twenty-six patients divided into two equal groups, where
fixation in group A utilized computer guided patient specific guide to fix anterior mandibular fractures using
lag screws. In group B anterior mandibular fractures were fixed using lag screws in the conventional way.
Both groups were compared in terms of stability and the need of auxiliary fixation devices.
Results: Both techniques showed uneventful healing and showing insignificant difference between them
concerning stability and the need for auxiliary fixation device.
Conclusion: Although the use of computer guided technology didn’t offer significant advantage over the
conventional technique yet it provides more easy and reliable way especially for beginners introduced to
the technique.
