PurposeThe incidence of fractures of edentulous mandibles is relatively low. Knowledge about the management of these fractured edentulous mandibles relies heavily upon case reports and observational studies. Based on current literature, we compiled a treatment protocol for fractures of the edentulous mandible and hypothesized that this protocol results in fewer complications.Patients and MethodsWe conducted a retrospective cohort study of edentulous patients with mandibular fractures. The predictor variable was the fulfillment of the treatment protocol (yes, no). The outcome variables were postoperative complications and reoperation. Demographic variables of patients were collected from patient records. A chi-square test was used for statistical analysis between predictor and outcome variables.ResultsOf 61 edentulous mandibular fractures (36 patients), 53 fractures were treated according to the protocol and 8 were not. Four complications were observed first group in the (complication rate 4/53=7.5%) and four in the second group (complication rate 4/8=50%). The fracture treatments that followed the protocol had a significantly (p=.001, OR=.082) lower postoperative complication rate, and needed fewer reoperations (p=.0001, OR=.019) compared to the treatments that did not follow the protocol.ConclusionThe results of this study show that following the compiled treatment protocol for fractures of edentulous mandibles significantly reduces postoperative complications and reoperations.
