It is not often that the oral and maxillofacial surgeon is faced with the challenge of restoring a defect that involves the entire mandible. The case presented in this article illustrates the management of such a case. Trauma, infection, neoplasm, and congenital malformations can lead to a discontinuous, deficient, or even absent mandible. In planning the reconstruction of a discontinuity of the mandible, the surgeon may need to manage one or more problems, including loss of adequate denture-bearing bone, loss of speech articulation, loss of control of the tongue and masticatory function, xerostomia as a result of the loss of sublingual and submandibular glands, loss of an intact deglutition mechanism, and a loss of facial form.
