Abstract

Objectives: The current study utilized virtual surgical planning for surgical splint-assisted mandibular fracture reduction and fixation by miniplates and screw in comparison to conventional Erich arch bar application. Patient and methods: twelve patients having parasymphyseal or body fractures were included in the study. Their ages ranged between 20 and 43 years. Patients were randomly divided into two equal groups; Study group (n=6): mandibular fracture reduction was achieved by virtual surgical planning for lingual splint fabrication and application. Control group (n=6): mandibular fracture reduction was achieved by Erich arch bar. The patients were clinically and radiographically evaluated through assessing operation time, occlusion by T scan and bone density.Results: The operating time of the study group 20.67 ± 5.05 min was statistically significantly lower than in the control group 48.5 ± 7.94 min. The occlusion improvement of the study group was significantly better than control group after both 1 week and 3 months. There was significant increase of bone density after 3 months in both groups.Conclusions: Virtual surgical planning for surgical splint (VSPSS) simplifies the reduction and fixation of mandibular fractures, especially those which are displaced lingual, decrease operating time and improve fracture stability.
