Miniplate osteosynthesis of fractures of the edentulous mandible

摘要: This study was performed to analyze treatment of fractures the edentulous mandible and discuss this method in relation mandibular height at fracture site. Fifteen sites 11 patients with an were retrospectively examined. These located: nine body, three paramedian region, angle. Fractures a measuring more than 10 mm vertical treated one miniplate. extremely atrophic or less using two miniplates, also modified Champy plate 1.3 thickness. A 5 combination microplate on buccal side miniplate inferior border additional direct circumferential wiring. Oblique splitting wiring Herbert screw, site each, respectively. Complications, including infection, fibrous union, nonunion trismus, not seen. In patient, hypesthesia lower lip was, however, persistent 1 month after surgery. Miniplate osteosynthesis is invasive treatment, it suitable for mandible, except comminuted defect fractures. To obtain stable fixation severely mandibles, we need consider use miniplates microplates.
