“…Furthermore, inter-abutment distance varied between 7 to 15 mm in different studies (Keulemans et al, 2009;Mehl et al, 2010;Nakamura et al, 2003;Shah et al, 2009;Song et al, 2003;Waki et al, 2006). In a previous study, it was reported that the fracture strength of inlay-retained FDPs reinforced with FRC was reduced by about 25 to 35% when the inter-abutment distance was increased from 7 to 11 mm (Song et al, 2003).…”

“…Moreover, the morphology of the pontic may also affect the fracture strength 13 (Özcan et al, 2005a). Recent studies presented significant differences between different pontic forms (Chen et al, 2011;Keulemans et al, 2009). In this study, the steel ball form was used to avoid any interference of the cusp height that could affect the results.…”

“…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). Conventional full-coverage or implant-retained FPDs could be considered invasive, time-consuming, and expensive (Keulemans et al, 2009). For patients who normally could not be treated with fixed appliances because of these factors, an FRC FDP can be offered as a single tooth replacement at much lower costs.…”

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.

“…The clinical situation could be simulated by investigating non-rigidly mounted abutments with an elastic modulus similar to that of natural teeth 4,30) . Although the physiological mobility of teeth was simulated with an emulated periodontal ligament, it must still be emphasized that steel abutments with an elastic modulus of 180 GPa were used, whereas natural teeth only have an elastic modulus ranging approximately from 15 (dentin) to 85 (enamel) GPa.…”

“…Another study showed that increasing the elastic modulus of the abutments results in increased fracture load [21]. Nonrigidly mounted abutments with an elastic modulus similar to that of natural teeth behave similarly to the clinical situation [2,22]. In addition, in this study the FDPs Constant clinical occlusal forces of 12 to 90 N and occasional maximum forces up to 909 N in posterior areas can be assumed depending on the type of measurement, gender, restoration type, diet, and other parameters [24].…”

OBJECTIVE: This study tested the fracture load of milled and conventionally fabricated polymeric and glass-ceramic three-unit fixed dental prostheses (FDPs) after aging. MATERIALS AND METHODS: FDPs were fabricated (N = 1,050) from four computer-aided design and computer-aided manufacturing (CAD/CAM) resins: (1) AT (artBlock Temp); (2) TC (Telio CAD); (3) ZP (ZENO PMMA); (4) CT (CAD-Temp); two conventionally fabricated resins, (5) IES (integral esthetic press), (6) CMK (CronMix K), and a glass-ceramic (control) (7) PG (IMAGINE PressX). Specimens of each group were tested immediately after fabrication (n = 15 per material). Seventy-five FDPs per material type were stored in artificial saliva (37°C) and 15 of them were randomly selected after aging (1, 7, 28, 90, and 180 days) for fracture load measurement. The remaining specimens (n = 60 per material) were subjected to chewing simulation (×120.000-1.200.000, 49 N, 5°C/50°C). The data were analyzed using two-way and one-way ANOVA followed by Scheffé test. RESULTS: The interactions between FDP materials and aging time in both storage media showed a significant impact on the results (p < 0.001). Among saliva storage groups, TC and ZP showed the highest, and PG the lowest fracture load (p < 0.05). AT and CT were not affected from chewing simulation. TC, ZP, and AT presented the highest in ascending order (p < 0.05), PG and CMK showed the lowest fracture load after chewing simulation (p < 0.001). CONCLUSIONS: Aging did not influence the fracture load of FDPs made of CAD/CAM resins. FDPs made of glass-ceramic showed significantly lower fracture load than those of all resin FDPs. Clinical relevance: Considering fracture load measurements, CAD/CAM resins tested could be alternative materials to glass-ceramic for FDP construction.
