Effect of Three Types of Temporary Luting Cements and Abutment Surface Sandblasting on Retentive Strength of Implant-Supported Fixed Prostheses
Background and Aim: Achieving appropriate retention and easy retrieva bility at the same time is challenging in implant-supported fixed par tial dentures (FPDs). Researchers have always been in search of a temporary cement to improve the retentive strength. The aim of this in vitro study was to evaluate the effect of three different temporary ce ments and sandblasting of the abutment surface on...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Effect of Aluminoborate Polycarboxylate Cements WhiskersonMechanicalPropertiesof
The mechanical properties of polycarboxylate cements containing 20 massO/o of fbur kinds of aluminoborate whiskers with ditTercnt fiber lengths and diameters were eva]uated. Bending strength of the cements inereased with increase in fiber length, whereby the strength ol' the cement with the longest fiber was about two times greater than that ef whisker-free cement, The diametral tensile strengt...
متن کاملThe inter-reaction of polycarboxylate cements with different adherened via pH and titration measurements.
Abract: This investigation was Planned to study, by PH measurements and titration method quantitively, the inter action of free acid group present in each mix of different types of poly carboxylate cements with enamel, dentin, Copper, chromium Oxide and nickel. Results: it was found that, the highest PH value in case PCA cement and highest reachivity when compared with Durelon and carboxylon ce...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
