[Comparison of the results in 59 patients with mandibular fractures treated by internal rigid fixation and inter maxillary ligation].

Purpose: The purpose of this study is to explore the clinical effect of the miniplate osteosynthesis on the treatment of mandibular fractures.

Methods: 59 patients with mandibular fractures were randomly divided into two groups. In the first group,29 patients underwent arch bar splints fixation and intermaxillary ligation. In the second group, miniplate osteosynthesis and intermaxillary ligation were performed in 30 patients.

Results: In the two groups,it was found that there was no significant difference in the postoperative infection and bone healing whereas the difference of occlusal relation,mouth opening and weight change was statistically significant.

Conclusions: From this study,we conclude that miniplate osteosynthesis may be an appropriate and effective method for the treatment of mandibular fractures. As to rehabilitation of occlusal relation and mouth opening,it is much better than intermaxillary fixation.
