Key considerations for achieving long-term stability of implant removable partial dentures

Abstract

Implant removable partial denture (IRPD) have attracted attention as a treatment modality that can improve the support and stability problems associated with conventional removable partial dentures. However, clear clinical guidelines regarding case selection, treatment strategies, implant positioning, and prosthetic design for IRPDs have not yet been fully established. This article discusses key considerations for achieving long-term functional stability of IRPDs based on the author’s clinical experience and previously reported studies. Three treatment strategies are presented: a planned soft landing to implant overdentures (IODs), conversion of distal extension cases into bounded edentulous spaces by implant support, and recovery treatment utilizing existing implants. Through these strategies, the clinical significance of positioning IRPDs as part of a flexible and adaptable treatment process, rather than a definitive prosthetic solution, is highlighted.
