{Abstract}: The stability provided by load-sharing miniplate osteosynthesis (LSMO) in dentate mandibular fractures (DMF) is usually adequate for bony healing. Non-union following LSMO is an uncommon complication. We aimed to determine the incidence and identify contributing factors, if any, of non-union amongst DMFs that have undergone LSMO. This retrospective case-control study with an allocation ratio of 1:3 includes cases of non-union DMF following LSMO and controls with healed DMF following LSMO over a five-year period. Relevant sociodemographic data, mandibular fracture characteristics, and treatment variables were collected for both groups. Of the 381 patients who underwent LSMO for DMFs, 12 cases of non-union were identified. The control group included 36 patients with uncomplicated healing. A significant association was observed between non-union and teeth in the line of fracture, postoperative infections, and time from injury to LSMO. The odds ratio with chronic alcohol usage was 1.4. Vigilant follow up of patients with chronic alcohol use, those with teeth in the fracture line, and adherence to LSMO principles may help to minimise the non-union complication.
