Role of occlusion in complications of implant rehabilitation / 中华口腔医学杂志

ABSTRACT

Peri-implantitis, restoration loosening and fracture, implant structural damage are common post-restorative complications in implant rehabilitation. With an increasing incidence, they may occur in implant-supported single or splinted crowns, bridges, overdenture or fixed denture. Possible causes involve not only the design of implant components structure and characteristics of restorative materials, but also the design of restoration and the occlusal function and structure of patients. Despite the hard texture of teeth, occlusal force may cause abrasion to occlusal and proximal aspects, as well as mesial migration of tooth, leading to continuous change of occlusal structure and function through the whole life. It should be considered in implant placement surgery, design and maintenance of restorations. From considerations of occlusal function and structure, the present article reviews and elaborates the effect, potential hazard, management and prophylaxis of post-implant-restorative complications.
