“…However, low bond strength of metal and ceramic FDPs to the tooth tissues remains to be the clinical problem leading to frequent debondings (Creugers et al, 1997;Kern and Sasse 2011;Kerschbaum et al, 1996). As a consequence of different modulus of elasticity of the different materials and the repeated stresses, the adhesive joint was often reported to be the main cause of failure (Behr et al, 2002;Creugers et al, 1997;Kerschbaum et al, 1996;Kumbuloglu et al, 2008). One alternative to metal or ceramic resin-bonded FDPs is fiber reinforced composite (FRC) FDPs that require minimal preparation of the tooth tissues, especially when compared with their conventional metal and ceramic counterparts (Özcan et al, 2005a;Ries et al, 2006;Waki et al, 2006).…”

“…In order to overcome this problem, pre-impregnated FRC systems are developed, meaning that the FRC bundle can be applied as such when taken out of the package (Miettinen et al, 1998;Vallittu, 1998Vallittu, , 1994. Monomers such as UTMA and bis-GMA/PMMA, changes handling properties and cross-linking, thereby, increase the adhesive strength of the FRC to the PFC (Kumbuloglu et al, 2008). On the other hand, the development and improvement of PFCs has been a great challenge for the manufacturers.…”

“…Pre-impregnation can be achieved with monomers, polymers or a combination of two or more of methacrylate monomers. Pre-impregnation is often performed using various monomers, such as bisphenol glycidylmethacrylate (bis-GMA), urethane dimethacrylate (UDMA), urethane tetramethacrylate (UTMA), polymethylmethacrylate (PMMA) or triethylene glycidylmethacrylate (TEGDMA) (Kumbuloglu et al, 2008;Lastumäki et al, 2003;Minesaki, 2002;Pensler et al, 1997;Vallittu, 1999). Effective impregnation allows the matrix to come into contact with the surface of each fiber (Vallittu, 1995).…”

“…Resin-bonded fixed dental prostheses (FPDs) with metal or ceramic frameworks are considered as minimal invasive treatment modalities (Creugers et al, 1997;Kern and Sasse 2011;Kerschbaum et al, 1996;Kumbuloglu et al, 2008;Wyatt, 2007). Such restorations serve as a practical and conservative approach in dentistry.…”

The load-bearing capacity and failure types of indirect inlay-retained fixed dental prostheses (FDP), made of particulate filler composite (PFC) (Estenia) alone or reinforced with E-glass fibers impregnated with various monomers were evaluated. Indirect inlay-retained FDPs were made between first premolars and first molars (N=30, 10/per group). The inlay parts of the specimens were silica coated and silanized and the specimens were cemented with dual-polymerized resin cement under ultrasonic vibrations. The experimental groups were as follows: Group 1: FRC1 (BR-100, UTMA) + PFC; Group 2: FRC2 (everStick CB, Bis-GMA/PMMA) + PFC; Group 3: PFC only. The specimens were kept in distilled water at 37°C for one month and then subjected to fracture strength test. No significant difference was found between the Group 1 and Group 2 FDPs (1357±301 N and 1213±316 N, respectively) (p>0.05) (ANOVA). Group 3 (856±299 N) showed significantly lower results than those of FRC reinforced groups (p<0.05). Failure analyses revealed no debonding of any of the FDPs from the inlay cavities. FDPs made of PFC only showed mainly catastrophic fracture of the pontic. In the FRC reinforced groups, predominantly delamination of the veneering was observed. The use of silica coating and silanization in combination with the dual-polymerized resin cement used; under ultrasonic cementation procedure provided sufficient adhesion to withstand static loading forces at the cementation interface, since the failures were predominantly delamination of the veneering in the FRC reinforced groups. alone or reinforced with E-glass fibers impregnated with various monomers were evaluated. In the FRC reinforced groups, predominantly delamination of the veneering was observed. Materials and Methods Conclusions:The load-bearing capacity of the indirect inlay-retained FPDs made of PFC reinforced with both BR-100 and everStick C&B revealed statistically similar results that were significantly higher than PFC alone. The use of silica coating and silanization in combination with the dual-polymerized resin cement used; under ultrasonic cementation procedure provides sufficient adhesion to withstand static loading forces at the cementation interface, since the failures were predominantly 3 delamination of the veneering in the FRC reinforced groups.

OBJECTIVES This prospective clinical study evaluated the performance of indirect, anterior, surface-retained, fibre-reinforced-composite restorations (ISFRCR). METHODS Between June-2003 and January-2011, a total of 134 patients (83 females, 51 males, 16-68 years old) received 175 ISFRCRs (local ethical registration number: 14/9/4). All restorations were made indirectly on a plaster model using unidirectional E-glass fibres (everStick CB, StickTech) in combination with a laboratory resin composite (Dialogue, Schütz Dental) and cemented according to the instructions of 4 resin cements [(RelyX ARC, 3M-ESPE, n=61), Bifix DC, VOCO, n=45), Variolink II (Ivoclar Vivadent, n=32) and Multilink (Ivoclar Vivadent, n=37)]. After baseline recordings, patients were followed at 6 months and thereafter annually up to 7.5 years. The evaluation protocol involved technical (chipping, debonding or fracture of tooth/restoration) and biological failures (caries). RESULTS Mean observation period was 58 months. Altogether, 13 failures were observed [survival rate: 97.7%] (Kaplan-Meier). One catastrophic fracture [(cement: RelyX ARC), eight partial debonding (cement: Bifix DC (5), Multilink (1), RelyX ARC (1), Variolink II (1)] and four delaminations of veneering composite [(cement: Bifix DC (2), RelyX ARC (1), Multilink (1)] were observed. Except one replacement, all defective restorations were repaired or recemented. Annual failure rate of ISFRCRs was 1.73%. The survival rates with the four resin cements did not show significant differences (RelyX ARC: 98.3%; Bifix DC: 93.5%; Variolink 2: 100%; Multilink: 100%) (p=0.114). Secondary caries did not occur in any of the teeth. CONCLUSION The 3-unit anterior indirect surface-retained resin-bonded FRC FDPs showed similar clinical survival rate when cemented with the resin cements tested. Experienced failures in general were due to debonding of the restoration or delamination of the veneering composite. CLINICAL SIGNIFICANCE 3-unit surface retained resinbonded FRC FDPs could be considered minimal invasive and cost-effective alternatives to conventional tooth-or implant-borne FDPs. Failures were mainly repairable in the form of chipping or debonding depending on the resin cement type. Variolink 2: 100%; Multilink: 100%) (p=0.114). Secondary caries did not occur in any of the teeth. Conclusion:The 3-unit anterior indirect surface-retained resin-bonded FRC FDPs showed similar clinical survival rate when cemented with the resin cements tested. Experienced failures in general were due to debonding of the restoration or delamination of the veneering composite.Clinical Trial Registration Number: NCT02343796.

Background/purpose: In the most recent decade, the use of all-ceramic and fiberreinforced composites as inlay-retained fixed partial dentures has increased. There are limited studies of comparisons of the mechanical strength and bending of these restorations. The aim of this in vitro study was to compare the fracture strength and the amount of bending in allceramic and fiber-reinforced composite inlay-retained fixed partial dentures. Materials and methods: Forty mandibular premolars and 40 mandibular molars were collected. The specimens were randomly divided into four groups of 10 molars and premolars within each group, each with box-shaped proximal preparations. Two different all-ceramic systems (IPS e.max Press and ICE Zirkon) and two different fiber-reinforced composite systems (EverStick and Vectris) with a connector size of 16 mm 2 were used to restore prepared abutment teeth. After thermal cycling (5 and 55 C Â 5000), a vertical force was loaded to the center of the inlay-retained fixed partial dentures at a crosshead speed of 0.5 mm/min. Failure types of specimens were examined with a stereomicroscope and radiography. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Mann-Whitney-U tests (a Z 0.05). Results: Fracture strengths were significantly higher in the ICE Zirkon (1540 N) and EverStick specimens (1057 N) than in the Vectris (794 N) and IPS e.max Press specimens (606 N) (P < 0.001). The amount of bending was significantly greater in the EverStick (1.94 mm) and Vectris (1.87 mm) specimens than in the ICE Zirkon (1.07 mm) and IPS e.max Press specimens (1.18 mm) (P < 0.001).Journal of Dental Sciences (2012) 7, 159e164Conclusions: Zirconia-based ceramic inlay-retained fixed partial dentures demonstrated the highest fracture strength. The fiber-reinforced composite inlay-retained fixed partial dentures demonstrated higher bending values than did the all-ceramic inlay-retained fixed partial dentures.
