Consideration of current treatment options for partially edentulous arch with a focus on implant-assisted removable partial dentures

Abstract

There are some treatment options available for people with partially edentulous arch; conventional removable partial dentures, implant-supported fixed prostheses, shortened dental arch, and implant-assisted removable dentures (IARPDs). IARPDs, the strategic addition of implants beneath the denture base, may be a more appropriate option in certain circumstances, although the reliability of combining natural teeth and dental implants in one removable prosthesis is controversial. Various factors can affect treatment planning, such as aesthetic or functional demands, treatment costs, oral hygiene, extent of ridge resorption, condition of remaining teeth, interocclusal space, and general medical condition. In general, IARPDs can demonstrate great advantages over conventional removable partial dentures in the denture stability, comfort due to simplified shape of denture base, and aesthetics related to metal clasps. Additionally, IARPDs can be more favorable than implant-supported fixed prostheses in regard to the minimally invasive surgical procedure, reducing economic cost, aesthetic restoration of facial collapse, and ease of maintenance. However, there is no standardized protocol of IARPD treatment so far because of the lack of clinical evidence. The purpose of this article is to organize current clinical information of IARPD treatment in a logical manner, as it relates to clinical features, literature-based consideration, and clinical tips with the view to a better prognosis and a greater patient satisfaction.
