The Optimal Position of the Implant Supporting Distal Extension Removable Denture: Case Reports and Literature Review

The management of distal extension edentulism by removable partial denture (RPD), in cases where fixed solutions cannot be considered, poses various challenges inherent in the mixed support of the prosthesis, especially when the edentulism is of a large extent. When an implant is placed to assist a removable denture, it allows ensuring a bio-functional, aesthetic, and comfortable rehabilitation. Additionally, it renders possible resolutions to problems related to conventional RPD. The implant can be placed in proximity or at a distance from abutment teeth, with each position presenting its own advantages and benefits. The choice of the optimal position is made following a clinical examination and cone beam computed tomography. Through two clinical cases, we will illustrate the management of distal edentulism with implant-assisted RPD, then review the key elements to consider during the prosthetic realization in the management of extended edentulism and discuss the parameters involved in the choice of preferred implant sites.
