Prosthetic Rehabilitation of a Maxillectomy Patient with Restricted Mouth Opening Using an Altered Cast Technique: A Case Report

Deformity in the maxillofacial region caused by surgical resection of a tumor have an adverse effect on the patient's ability to swallow, masticate, phonate, and psychological state. These patients may have restricted mouth opening capacity due to several surgical procedures and scar contracture resulting from radiation therapy. Therefore due to restricted access to the oral cavity prosthetic rehabilitation of these patients becomes a challenging task. A precise impression of the resection defect is necessary for accurate obturation. This is not practical for patients who have restricted mouth opening, hence this crucial first step in the making of a good prosthesis is frequently accomplished by altering the conventional impression method. This clinical report details the prosthetic rehabilitation of a patient who was diagnosed with Adenoid cystic carcinoma of the left maxillary sinus. Patient underwent maxillectomy for tumor removal, which was worsened by trismus as a result of the procedure and radiation therapy. For orofacial rehabilitation and defect obturation, the patient was restored with a removable dental prosthesis with a hollow bulb obturator. An altered cast technique was used in the final impression making. This rehabilitation approach was successful in restoring lost function and appearance of the patient.
