Rehabilitation of a Patient with Combined Hemimaxillectomy-hemimandibulectomy Defect using Unilateral Implant-supported Magnet-retained Prosthesis: A 3-year Follow-up

Abstract

A 60-year-old patient presented with complaints of difficulty in chewing and deteriorating systemic health [Table/Fig-1]. The medical history revealed squamous cell carcinoma affecting the right part of the maxilla and mandible, which was surgically treated 15 years ago. The surgical intervention involved the removal of the maxillary alveolus, tuberosity, mandibular condyle, and coronoid process, extending up to the mandibular midline. Soft tissue reconstruction was performed to address the maxillary defect. There was a recurrence of the carcinoma, which was managed through radiotherapy. The patient had controlled diabetes and hyperthyroidism and was on medication for these conditions. On examination, a hemimaxillectomy without oronasal fistula and a hemimandibulectomy that included the condyle were observed. Decayed root stumps with periapical radiolucencies [Table/Fig-2] were extracted. The presence of a scar band in the right cheek ruled out the possibility of placing zygomatic or pterygoid implants. Furthermore, the patient expressed unwillingness to undergo an extensive and invasive reconstructive surgery due to personal reasons.
