Shear Bond Strength Comparison between Conventional Dental Nano Zirconia Combinations and New Functionally Graded Nano Zirconia Combinations after Thermal-Mechanical Cycling
The aim of the study was to evaluate the core veneer bond strength of graded zirconia combinations and compared those to conventional zirconia combinations after thermal and mechanical tests. Conventional zirconia-veneer combinations and graded zirconia-veneer combinations were made into cylinders. Prior to shear bond testing, half of each group was subjected to thermal and mechanical cycling t...
متن کاملEffect of framework design on fracture load after thermal cycling and mechanical loading of implant-supported zirconia-based prostheses.
This study evaluated the effect of zirconia framework design on fracture load of implant-supported zirconia-based prostheses after thermal cycling and mechanical loading. Three different zirconia framework designs were investigated: uniform-thickness (UNI), anatomic (ANA), and supported anatomic (SUP) designs. Each framework was layered with feldspathic porcelain (ZAC group) or indirect composi...
متن کاملEffect of resin coat technique on bond strength of indirect restorations after thermal and load cycling.
OBJECTIVE To evaluate the ability of the resin-coat technique used in cavity preparation to protect dentin before impression taking and final cementation and its effect on the tensile bond strength of indirect restorations after thermal and load cycling. METHODS Occlusal enamel was removed from 25 third molars to expose flat dentin. Teeth were divided into 5 groups (n=5): G1, receiving no den...
متن کاملThermal contact conductance and its dependence on load cycling
Heat transfer between contacting surfaces is an important factor in the thermal behaviour of engineering components in turbomachinery and various other areas of technology. Thermal contact conductance (TCC) is a parameter that quantifies this heat flow. Any theoretical prediction of TCC should take into account the effects, if any, introduced by repeated loading and unloading. This study aims t...
متن کاملeffect of mechanical load cycling on microtensile bond strength of self-etch systems to dentin
objective: optimal dentin bonding is not always obtained in clinical practice due to func-tional forces. these forces may provide stresses throughout the tooth and restorative sys-tem, which in turn may affect the adhesive bond. this experimental study evaluated the effect of load cycling on bond strength of self-etch systems. materials and methods: one third of the coronal portions of 48 intac...
