Abstract The objective of this study was to evaluate clinically and radigraphically the use of mini dynamic compression plates system in acceleration of bone healing in mandibular fractures. The study was conducted on ten patients with mandibular fracture in the tooth-bearing area requiring reduction and fixation, they were randomly selected from the cases received in the Emergency Room of Alexandria University Hospital and treated in the operating room of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. Patients evaluation All cases were evaluated as follows: - History, including present history of the trauma and past medical history. - Clinical examination included both general and local examinations. - Radiographic examination using orthopantograms (OPG) and posteroanterior view (PA) according to the case. - Both maximum mouth opening and bite forces were measured preoperative to be considered as baseline. Surgical procedures - Upper and lower arch bars or eyelets were applied followed by exposure of the fracture line using intraoral incision. - Temporary IMF was done followed by fixation of the fracture using mini DCPs and mini screws then releasing of IMF. Clinical and radiographic follow up Clinical postoperative follow up was done for 12 weeks posteoperative to evaluate pain, edema, maximum mouth opening, bite force, wound healing, sensory function, teeth vitality and occlusion. Radiographical follow up was done to evaluate the bone healing progression and measure the bone density using image J program. Clinical and radiographic results Clinical results revealed significant decreasing in pain intensity and edema across all follow up periods. The results also showed significant increase in both bite force and mouth opening. Neither disturbed occlusion nor infections were reported in our study. Two cases needed root canal treatment for the teeth in the fracture line postoperatively. The sensory impairment was noted in three cases but all cases regained their sensory function by the end of the follow up period (12 weeks). Radiographic follow up revealed good alignment of the fracture segments and significant increasing in bone density. |
