Intraoral extra-mucosal fixation of fractures in the atrophic edentulous mandible

Atrophy of the mandible leads to a decrease in the bone mass, making it more vulnerable to fractures. A direct relationship has been demonstrated between the height of the bone in the area of the fracture and the incidence of postoperative complications of bone healing. Basic principles of fracture management in both edentulous and non edentulous patients are open reduction and internal fixation with osteosynthesis of the fracture to achieve restoration in terms of aesthetics and functionality. Several authors have discussed the advantages and disadvantages of the transoral and extraoral approaches. Between January 2007 and June 2011, 13 patients affected by bilateral fractures of atrophic mandibles were treated by extra-mucosal intraoral stabilization with satisfactory results. This approach reduces the risks of damage of the marginalis mandibulae nerve with low operation time, while avoiding unsightly scars.
