Özet

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.
