A clinical case report on indirect, posterior three-unit resin-bonded FRC FPD.
OBJECTIVE
This paper describes a clinical, conservative approach and the details of cavity preparation for the replacement of a maxillary first premolar using a minimally invasive preparation combined with the adhesive approach.


METHODS
A patient with a missing first premolar was treated with a 3-unit indirect fiber-reinforced composite (FRC) fixed dental prosthesis (FDP). The preparation on the canine was a slot combined with modified wing to increase the amount of fiber in the restoration. Glass fiber (Vectris; Ivoclar Vivadent) was used in an anatomical shape for the framework and incrementally veneered with resin composite (Adoro; Ivoclar Vivadent). The cavities were prepared by etching enamel and dentin with orthophosphoric acid, priming the dentin, and applying a three-step adhesive system and dual-cured luting resin (Variolink II, Ivoclar Vivadent). Finally, the indirect FRC FDP was finished and polished with 15-µm diamond burs (Composhape, Intensiv) and a polishing kit.


RESULTS
The patient was satisfied with the esthetics and function of the restoration, which has served without repair for 5 years. At the 5-year clinical follow-up, the restoration was found to be clinically successful.


CONCLUSIONS
The correct cavity-preparation technique in combination with the FRC system could enhance the long-term survival of an inlay FDP.
