Considering the usefulness of single-retainer resin-bonded fixed dental prostheses and endocrowns

Abstract

This article provides a comprehensive review, based on existing literature, of the utility of single-retainer resin-bonded fixed dental prostheses (RBFDPs) and endocrowns, modalities developed in line with the Minimal Intervention (MI) concept. The single-retainer RBFDPs utilize only one abutment tooth, minimizing the removal of tooth structure. Evidence suggests a more favorable long-term prognosis for this design compared to conventional two-retainer prostheses. Meanwhile, the endocrown is a post-free restoration for non-vital teeth that gains retention from the morphology of the pulp chamber, thereby reducing invasive procedures on the root and conserving enamel. The clinical success of both treatments depends on appropriate case selection, a thorough understanding of material properties, and meticulous adhesive techniques. Consequently, these restorations are anticipated to become standard options in the future for prosthodontic treatments.
