Abstract

This study evaluated the performance of indirect, anterior, surface-retained, fiber-reinforced-composite restorations (ISFRCR). Between September-2011 and September-2012, 17 patients (13 females, 4 males, mean age: 40.5) received 17 indirect ISFRCRs (maxilla=4; mandible=13). All restorations were made on a plaster model using unidirectional E-glass fibers (Interlig, Angelus) in combination with a veneering resin composite (Gradia, GC) and
cemented adhesively (Choice 2, Bisco). No cavity preparations were made on the abutment teeth. Before cementation, enamel surfaces were cleaned with pumice and etched with 38% H3PO4 for 30 s, rinsed 30 s. Then, adhesive resin was applied accordingly. Patients were followed every 3 months until May 2014. The evaluation protocol involved technical (chipping, debonding or fracture of tooth/restoration) and biological failures (caries). Survival (Kaplan Meier) and annual failure rates were calculated. Mean observation time was 34.6 months. Altogether, 5 failures were observed [survival rate: 70.5%] of which 3 were debondings and 2 delaminations of the veneering composite (chipping). All defective restorations were repaired or recemented, except one, which was remade.
