Adhesive Resin Cementation of Posterior Hybrid-type Retainer Porcelain Fused to Metal Fixed Dental Prostheses

Abstract

Porcelain fused to metal (PFM) of fixed dental prostheses (FDP) remains the gold standard for rehabilitating partial edentulous. However, conventional PFM FDP requires lengthy procedures to achieve optimum retention, resistance, and esthetics, such as the geometry and depth of preparation. Adhesive technology could minimize the complexity of cementation to achieve retention and resistance by minimizing the preparation area, thus ruling out the geometry of preparation consideration. The optimal geometry of preparation is achieved by the preparation of a tooth structure with significant depth and geometry. Thus, abandoned preparation geometry increases the use of minimally invasive prosthodontics. Minimally invasive prosthodontics could minimize the possibility of future endodontic treatment. One option for treating partially edentulous patients with a minimally invasive approach is the hybrid PFM FDP, consisting of an inlay-bonded retainer with the vital tooth in one of the abutments and a conventional retainer with the non-vital tooth in the other. As a result, this report showed the reasoning and technology for cementation of hybrid-type retainer PFM FDP using adhesive technology in the posterior area. Findings uncovered that using adhesive technology, the cementation FRC FDP of hybrid-type retainer PFM FDP could minimize the preparation and cementation procedure without compromising retention and resistance. Therefore, future usage of hybrid-type retainer PFM FDP should be encouraged from a minimally invasive point of view
