A case of，performed a recovery of oral functions by the prosthetic modification

Abstract

In this case (68 years old, female, at the time of initial examination), an implant overdenture was used for bilateral molar defects to restore oral dysfunction due to masticatory disorders caused by ill-fitting dentures. In an oral cavity with multiple missing teeth, it is necessary to provide an appropriate mandibular position and to construct an occlusal position to maintain it. In some cases, orthodontic treatment is necessary to correct the malpositioning of the remaining teeth, and an implant prosthesis is the first choice to provide solid occlusal support for the missing teeth. However, considering the patient's wishes and financial background, the ideal treatment is rarely attained. In particular, prosthodontic treatment for partially edentulous dentition with existing implant prostheses is difficult due to the selection of prostheses and prosthetic design. In the present study, a mandibular dentition with bilateral molar defects was treated with an implant-assisted removable partial denture (IARPD) using an existing implant to restore oral function, which in effect led to desirable results.
