Abstract
This study was conducted to carry out retrospective analyses of oral peri-implant malignancy (OPIM) focussing on demographic details, risk factors, habit factors, clinicopathological features and implant features in patient with OPIM. Clinical data and demographic data from 1646 individuals with oral cancer undergoing resection procedures were gathered. Clinical, radiological, histopathological assessments and implant characteristics records of these patients were obtained and assessed. 46 (2.79%) cases were found to diagnose with OPIM. 36 (85.76%) cases of OPIM were found to having implant occlusion with opposing prosthesis. Prosthesis/prosthesis occlusion was observed in 18 (50%) cases, prosthesis/inlay occlusion in 4 (11.12%) cases and prosthesis/prosthesis on implants in 14 (38.88%) cases. The surgical placement of implants and the galvanic currents that flow between prostheses can operate as an irritating or inflammatory cofactor that aids in the development of malignancies.
