38th Annual Conference of the European Prosthodontic Association, İstanbul, Turkey, 25 - 27 September 2014, pp.247
Purpose: This clinical study evaluated the performance of indirect, anterior, surface-retained,
fiber-reinforced-composite restorations (ISFRCR).
Materials and Methods: Between September-2011 and May-2014, a total of 17 patients (13
females, 4 males, 29-65 years old) received 17 ISFRCRs at the Hacettepe University,
Turkey. All restorations were made indirectly on a plaster model using unidirectional E-glass
fibers (Interlig, Angelus) in combination with a resin composite (Gradia, GC) and cemented
according to the instructions of resin cement (Choice 2, Bisco). After baseline recordings,
patients were followed at 6 months and thereafter annually up to 3 years. The evaluation
protocol involved technical (chipping, debonding or fracture of tooth/restoration) and
biological failures (caries).
Results: Mean observation period was 25 months. Altogether, 4 failures were observed
[survival rate: 76.5%] (Kaplan-Meier). Two debonding of the restorations and two
delamination of the veneering composite (chipping) were observed. Except one, all defective
restorations were repaired or recemented. Annual failure rate of ISFRCRs was 0.11%.
Secondary caries did not occur in any of the teeth.
Conclusion: The 3-unit anterior indirect surface-retained resin-bonded FRC FDPs with the
fiber, veneering resin and cement could be advised as a semi-permanent treatment modality
at this stage. Experienced failures were either due to debonding of the restoration or
delamination of the veneering composite.
