Management of atypical occlusal discrepancy after condylar resection: A clinical report

Abstract

This clinical report describes the prosthetic management of occlusion for a patient who had received condylar resection as part of cancer treatment. Previous reports have identified that patients with unrepaired segmental resection of the mandible experienced a frontal plane rotation of the mandible toward the nonsurgical side. In contrast, because of preservation of temporomandibular muscles and their attachments, the mandible rotated toward the surgical side, and occlusal contacts were limited to a pair of molars on that side. Manual manipulation and instructions for muscular stretching and massages were provided to reduce muscular tension. A mandibular guidance prosthesis was fabricated and gradually adjusted to guide the mandible progressively toward a normal position. These treatments helped improve general comfort, mastication, occlusion, and the gradual rotation of the mandible toward a normal position.
