Abstract

Objective:Great debate raised on which open reduction and internal fixation treatment method is considered the optimal treatment modality.This study aimed to compare changes in the intercondylar distance following ORIF using conventional double miniplates, Intraosseous Herbert screw and 3D miniplates in anterior mandibular fracture.
Patients and methods: 27 patients with 27 anterior mandibular fractures were randomly allocated to three equal groups according to the method of fixation, Group A: Conventional double miniplates, Group B: Intraosseous Herbert screw and Group C: 3D miniplates. The primary outcome was changes of intercondylar distances immediately and after three months postoperative. Secondary outcomes were i) occlusion stability  and ii) wound infection & dehiscence at two weeks, three months postoperative.
Results: The three groups showed minimal and comparable changes in the intercondylar distance with no statistical significance difference between the three groups (P value 0.107).there was no statistical significance difference between the three groups after either two weeks or three months (P value 0.782 and 0. 354 respectively) regarding the occlusion stability. At the end of follow up period only one patient in group A still suffered wound infection & dehiscence and was scheduled for plate removal with no statistical significance difference between the three groups either two weeks or three months postoperative (P value 0.325 and 0.354 respectively). 
Conclusion: The conventional double miniplates, Herbert Intraosseous screws& 3D miniplates provided minimal changes in the intercondylar distance with satisfactory occlusion & minimal incidence of wound infection & dehiscence.
