Purpose: This retrospective clinical study evaluated the performance of indirect, anterior, surfaceretained, fibre-reinforced-composite restorations (ISFRCR).
Materials and Methods: Between September-2011 and September-2012, 17 patients (13 females,
4 males, 29–65 years old, mean age: 40.5) received 17 indirect FRC FDP at the Hacettepe University, Turkey. All restorations were made indirectly on a plaster model using unidirectional E-glass
fibres (Interlig, Angelus) in combination with a resin composite (Gradia, GC) and cemented adhesively with resin cement (Choice 2, Bisco). ISFRCRs were made in the anterior segment of the
maxilla (n = 11) and the mandible (n = 6). No cavity preparations were made on the abutment teeth.
The restorations were made at the dental laboratory by one dental technician. Before cementation,
enamel surfaces were cleaned with pumice and etched with 38% H3
for 30 seconds, rinsed
for 30 seconds. Then adhesive resin was applied accordingly. After baseline recordings, patients
were followed every 3 months up to 43 months according to previously defined criteria. The evaluation protocol involved technical (chipping, debonding or fracture of tooth/restoration) and biological
failures (caries). Patients were also instructed to call upon experience of a failure. Survival rates,
including repairable defects of FDPs, and success rates were determined (Kaplan Meier).
Results: Mean observation period was 34.6 months. Altogether, 5 failures were observed (survival
rate: 70.5%). Three debondings and two delaminations of veneering composite (chipping) were
observed. All defective restorations were repaired or recemented, except one, which was remade.
Conclusions: The 3-unit anterior surface retained indirect FRC FDPs with the E-glass fibre, veneering resin and cement could be advised as a semi-permanent treatment modality.
