Roh, Jeon, Jeong, Yoon, Lee, and Huh: Implant assisted removable partial denture with implant surveyed crown: A 20-month follow-up case report

Abstract

Traditional options for posterior edentulous treatment include removable partial dentures and implant fixed prostheses. Recently, the concept of implant assisted removable partial denture, in which two treatments are fused, has been introduced in consideration of systemic health and patient's needs, costs, residual alveolar bone status and so on. Implant assisted removable partial denture has the advantage of increasing the retention and stability of the denture and improving its esthetics in cases of large bone defects or biomechanical disadvantages. In addition, it is possible to strategically place the implants in a site where the alveolar bone is relatively sufficient, thereby overcome the limit of the conventional removable partial denture design as well as reducing the burden on a wide range of implant surgery. Cost reduction is also expected. In this case, the patient was treated by placing the implant in both premolar sites of the mandible and fabricating the distal extension removable partial denture with the implant fixed prosthesis as an abutment. After delivering the definitive prosthesis, the patient showed satisfaction with the masticatory function and esthetics. and has been regularly followed-up for more than one year. The following 20-months follow-up case report describes the design of an implant-assisted-removable partial denture (IARPD) in which two cementretained implant crowns used to provide support and stability.
