Effects of two preparation designs and pontic distance on bending and fracture strength of fiber-reinforced composite inlay fixed partial dentures

Load-bearing capacity of indirect inlay-retained fixed dental prostheses made of particulate filler composite alone or reinforced with E-glass fibers impregnated with various monomers

“…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).…”

“…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). All-ceramic inlay-retained FDPs are reported to have higher fracture strength values than their FRC reinforced counterparts.…”

Vertical marginal gap & retention of ceramic full coverage & inlay retained ceramic fixed partial dentures

“…The size of these preparation features depends on the size of the tooth. The tested design is the most used in CIRPFDs [10][11][12]50,53,58]. The dimension of the full coverage all ceramic FPDs were constructed according to Rosenstiel et al (2006) [65].…”

“…The occlusal preparation was 4 mm wide and extended 4 or 6 mm mesio-distally for the premolar or molar models, respectively. The proximal box was 1 mm wide and had approximately 5˚ divergence, extending 2 mm apical to the isthmus floor [53]. The preparations corresponded to a proximal connector area of 3 mm × 3 mm for molars and premolars.…”

Effect of fiber-reinforced composites on the failure load and failure mode of composite veneers

“…In the context of short-term evaluation periods, clinical studies of FRCs have shown a relatively high success rate [12][13][14] . In particular, the mechanical properties of FRC restorative materials have been shown to be enhanced by either using Received Dec 8, 2008: Accepted Feb 13, 2009 preimpregnated fibers beneath the composite resin restorative material or reinforcing the composite material with fiber impregnation 15,16) .…”
