FRC-FPD Is a New Alternative for Replacing a Missing Posterior Tooth

Take-Home Pearl: For patients who are unable to afford the conventional porcelain fused to metal 3-unit fixed partial denture (FPD) or an implant-supported prosthesis, a fiber-reinforced composite FPD serves as a great alternative.

Background: The traditional approach to replacing a missing posterior toothis with either a removablepartial denture (RPD) or a ceramic fused to metal or all-meta fixed partial denture (FPD). More recently, implants and implant-supported prostheses serve as a more predictable alternative. However, the cost of implants or an FPD may not be affordable for some patients. Thesefore, a less expensive and very predictable alternative to replacing a missing posterior tooth is with an inlay fiber-reinforced composite (FRC) resin fixed partial denture (FRC-FPD). These prostheses have glass fibers that reinforce the comporite allowing them resist compressive and tensile loads. Sufficient are critical, especially in the substructurepontic area, as the ost vulnerable component of the FRC-FPD restoration is the bond between the framework and the veneering material.

Objective: To describe "...a conservative, esthetic, and inexpensive treatment method for replacing a missing single tooth with an inlay-retained FRC-FPD and a fiber-reinforced pontic structure."

Methods: Case report.

Case Report: A 34-year-old male sought treatment for replacement of tooth #30. After obtaining informed consent, the denstist prepared teeth #29 and #31 for Class II inlays. A vinly-polysiloxane impression was obtained and poured up in green stone. A prefabricated fiber-reinforced pontic substructure system, a unidirectional pre-impregnated fiber bundle, and microhybrid composite resin were used to create the pontic, inlays into the abutment teeth, and composite framework for the FRC-FDP. The prosthesis was luted with adual-cure resin cement and followed up semiannually for 2 years and then annually for 4 more years. Occlusal contacts were added durung the fifth year.

Conclusions: For patients who are unable to afford the conventional porcelain fusd to metal 3-unit FPD or an implant-supported prosthesis, FRC-FPD serves as a great altenative.

Reviewer's Comments: This was an interesting case presentation, as it discussed an alternative to traditional prostheses when restoring a single missing posterior tooth. From a practical standpoint, I would be interested to see how dental insurance would cover such a prosthesis.
