Resolution of Excessive Interocclusal Restoration Space Post-Mandibulectomy Using a Two-Layer Retrievable Fixed Implant-Supported Prosthesis: A Case Report.

Patients treated with segmental mandibulectomy often require complicated rehabilitation. Maintenance of mandibular continuity and provision of adequate soft and hard tissue volumes are two key factors required for good clinical outcomes. Moreover, excessive interocclusal restoration space is a common problem in these patients. This case report describes the process of prosthetic rehabilitation from extensive surgical excision to final rehabilitation by using a creative two-layer fixed implant prosthesis in a 70-year-old patient with oral squamous cell carcinoma.
