Özet

Objectives: This clinical study evaluated the clinical performance of indirect, surface-retained fiber-

reinforced composite (FRC) fixed dental prosthesis (FDP). Methods: Between September-2011 and


May-2012, 13 patients (9 females, 4 males, 17-60 years old, mean age: 36.5) received a total number of

13 indirect FRC FDP at the Hacettepe University, Ankara, Turkey. All restorations were made indirectly

using E-glass woven fibers (Interlig, Angelus) in combination with resin composite (Gradia, GC), and

bonded using resin cement (Choice 2, Bisco). FRC FDPs were made in the anterior segment of the

maxilla (n=9) and the mandible (n=4). 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% H3PO4 for 30 seconds, rinsed 30 seconds.

Then adhesive resin was applied accordingly. After baseline recordings, patients were followed every 3

months according to previously defined criteria. Patients were also instructed to call upon experience

of a failure. Two calibrated operators performed additional qualitative analysis using modified USPHS

criteria. Results: Mean observation period was 7 months with a maximum of 9 months. Altogether, one

absolute failure in the form of fracture was observed in the maxilla due to trauma where the pontic was

12. This FRC FDP was renewed using the same protocol. According to USPHS criteria, no delamination

of the veneering composite or debonding of the restoration from the enamel surface was experienced.

Secondary caries and endodontic complications did not occur in any of the teeth. Conclusion: Except

one failure, preliminary clinical findings of 13 case series with surface-retained indirect FRC FDPs

demonstrated promising results up to maximum 9 months.
