Marginal Mandibulectomy and Oral Rehabilitation of Xeroderma Pigmentosum Patient

Xeroderma pigmentosum (XP) may cause tissue deformation in patients who have undergone oral cancer surgery requiring resection of any part of the mandible. Oral rehabilitation is a pivotal factor in the restoration of function and esthetics. The aim of this study was to report a clinical case of successful prosthetic rehabilitation of a 57-year-old woman who presented with marginal mandibulectomy and a significant reduction in maximal mouth opening after treatment for XP. With her reduced opening and considerable loss of structure and tissue, she had difficulty speaking, swallowing, and altered esthetics. The oral rehabilitation was performed with complete maxilla denture and mandible overdenture retained by 2 implants. This case demonstrates that the rehabilitation with mandible overdentures and complete maxilla dentures provide function and esthetic improvement in the mutilated area for XP patients with marginal mandibulectomies.
