Description

<p>In recent years, various factors other than bacterial infection related to peri-implant bone resorption have been attracting attention, and overload is one of the important factors. However, it is very difficult to distinguish whether the cause of bone resorption around the implant is overload or infection. In this study, we report a case in which bone resorption around the implant was improved by occlusal treatment.</p><p>The patient was a 49-year-old woman with the chief complaint of gingival swelling with 37. She had mandibular protrusion with open occlusion, 37 showed root fracture and there was bone resorption around the 47 implant. Implant placement was performed for 36 at 2 months after tooth extraction, anterior guidance was provided by a temporary prosthesis, and occlusal dissipation of the molars was improved. Bone resorption of parts of 47 fitted with the final superstructure was observed, and 9 years after the operation, the patient is doing well.</p>
