The Effect of Preparation Design on the Marginal Integrity of Monolithic Zirconia Crown
Abstract Background & Aim: Marginal adaptation of full ceramic zirconia restorations are one of the important factors in their long-term success and one of the factors affecting marginal adaptation and their strength is the finish line design.This study was conducted to compare the effect of finishline design on the adaptation of monolithic zirconia crowns. Material and methods: In this in-vitr...
متن کاملMarginal Strength of Collarless Metal Ceramic Crown
Metal ceramic restorations have been implicated for the discoloration in area of labiogingivalmargin. Attempts to rectify this, by altering the design of metal frameworkswill lead to decrease in fracture strength atmargin. This in vitro study compared the fracture strength at margins of metal ceramic crowns cemented to metal tooth analogs. Crowns evaluated with different marginal configurations...
متن کاملCastability and surface hardness of titanium cast plates obtained from experimental phosphate-bonded silica investment molds.
The effect of 12 different experimental compositions of phosphate-bonded SiO2 investments was examined on cast pure titanium. The mold temperature was 600 degrees C and the casting was conducted with an argon-arc melting and pressure casting machine. Castability was evaluated by the volume of casting porosity, which was calculated from the volume of wax pattern (15 mm x 15 mm x 1.5 mm), the wei...
متن کاملRetention of cast crown copings cemented to implant abutments.
BACKGROUND The cementation of crowns to dental implant abutments is an accepted form of crown retention that requires consideration of the properties of available cements within the applied clinical context. Dental luting agents are exposed to a number of stressors that may reduce crown retention in vivo, not the least of which is occlusal loading. This study investigated the influence of compr...
متن کاملFunctional studies cast light on receptor states.
Contemporary analysis of the functional responses of G-protein-coupled receptors (GPCRs) usually addresses drug-receptor interactions from the perspective of the average behavior of the receptor population. This behavior is characterized in terms of observed affinity and efficacy. Efficacy is a measure of how well a drug activates the receptor population and observed affinity a measure of how p...
