Abstract: Objective To investigate clinical efficacy of titanium plate internal fixation and intermaxillary wire ligation fixation in treatment of mandibular fractures.Methods From June 2009 to July 2012,42 retrospective analysis cases of mandibular fracture were collected.21 patients were treated with intermaxillary wire ligation fication,the remaining 21 patients accepted fitanium plate fixation.Two groups were compared in fracture healing,occlusion,biting force and infratemporal joint.Results 42 cases were followed up for 6-32 months.Titanium plate group was better than the wire group in clinical results including fracture healing,occlusion ,biting force and infratemporal joint (P<0.05).Conclusion Titanium plate internal fixation has excellent reduction,rigid fixation and fewer complications in treatment of mandibular fracture.It is an ideal menthod for treating mandibular fractures.

Key words: Mandibular fractures, Intermaxillary ligation, titanium plate internal fixation
