The use of many currently available implant systems may be limited in patients with severe mandibular atrophy because of the lack of available bone in the symphyseal region. The transmandibular implant is a rigid box-frame structure that can distribute masticatory forces along a severely atrophied mandible with as little as 4 mm of vertical bone with an implant-borne prosthesis. Although the success rate of the transmandibular implant is favorable as compared with other systems, complications can occur after placement, including infection, partial extrusion, and fracture of a post. A case report of fractures of two posts at the necks and the bar approximately 18 months after placement is presented.
