Abstract
This study was conducted on sixteen adult patients with mandibular angle fracture selected from the outpatient clinic, Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Tanta University. The selected patients were randomly divided into two equal groups, group I (8 patients) were treated by single 2.0 mm three dimensional customized titanium plate while group II (8 patients) were treated by single 2.0 mm conventional titanium miniplate according to Champy’s principle. A comparison between the two groups was conducted. Preoperative evaluation of the patients was carried out by taking history and performing clinical and radiographic examinations. Clinical examination included intraoral and extraoral inspection and palpation of the fracture sites. Radiographic examination was used to determine the site, number, type of fractures and degree of displacement. Under general anesthesia, the fracture line was exposed through an intraoral approach, and the fracture segments were reduced. In group I, fixation of the reduced segments was done with three dimensional customized titanium plate which predetermined virtually. In group II, one miniplate placed on superior border of external oblique ridge was used to fix the fracture. Postoperative clinical evaluation were performed immediately, one week, two weeks, one month, three months and postoperative radiographic evaluation were performed immediately, three months and six months. The postoperative clinical evaluation included presence or absence of infection, position of the mandibular lower border and bony union or stability, state of occlusion, maximal mouth opening, sensory nerve function, condition of teeth related to the fracture line and, patient’s tolerance to the plate. The postoperative radiographic follow up evaluated the accuracy of reduction by measuring the inter-fragmentary gap and intergonial distance. Wound healing was optimal in all cases of both groups except case no 4 of group II where dehiscence and mild infection was encountered. Satisfactry occlusion was obtained in all cases of both groups except case no 7 of group II where it had mild occlusal derangement. Other parameter including clinical stability, maximal mouth opening, sensory nerve function, and plate tolerance were comparable. There were no significant differences between group I and group II regarding inter-fragmentary gap and intergonial distance.
