Aim: To compare the use of computer guided technology to place lag screws in anterior mandibular fracture in comparison to convectional technique. Methodology : This study included twenty-six patients divided into two groups, where fixation in group A utilized computer guided patient specific guide and group B was fixed in the conventional way. Both groups were compared in terms of stability, neuro sensory disturbance and the need of auxiliary fixation devices.Results: Both techniques showed uneventful healing and showing insignificant difference between them concerning stability, neuro sensory disturbance and the need for auxiliary fixation device.Conclusion: Although the use of computer guided technology didn{u2019}t offer significant advantage over the conventional technique yet due to the technique sensitive entity of the lag screw technique we recommend the use of computer guided technique by beginners to the lag screw technique in order to achieve the required fixation without endangering vital structures
