Abstract
The purpose of this study was to find cause of the implant fracture and prevent it in a case. A 43-year-old Korean female patient visited to cement a fallen down prosthesis, 3-unit fixed partial denture which second premolar and molar of left mandible were abutment teeth in Novemeber 2006. Each abutment was restored to a single crown. A missing tooth , first mandibular molar was restored to implant prosthesis. Suddenly She visited our clinic again for the mobility of implant after 5 years. We diagnosed implant fracture of first mandibular molar implant and removed fractured implant. After 3 months, we installed a new implant. The patient was examined after 6months and the result was that the implant was maintained stable. Therefore, excessive occlusal forces cause a fracture of dental implants and it may be more appropriate for patients having heavy occlusal force to consider a greater number of implants to share in the functional load and implants of larger diameter, thereby making the implant more resistance to the forces that could cause fracture.
