Resistence of compression between a direct composite resin and two ceromers

Abstract

That review assessed the resistance of the fracture at the two laboratorial resins that if they find in the market, the one Artglass® and the other one Targis® as a bevy compared the direct composite resin TPH®. Five bodies as of he samples as of each resin the one being assayed were used. With the matrix of stainless steel assistance along form of a cone segment, along measurements internal as of 8 mm in diameter at the entry level 9 mm at the portion better and 4 mm as of height, have been made the bodies of proving. The samples have been maintained well into water deionizer by 72 hours and submitted to a bulk axial action from a butt as of border rounded in shape as of 2 mm bore, adapted to an appliance as of test across the board EMIC 500. The velocity was 0,05 mm/min, along a cell as of capacitance as of bulk of the 200 kgf. The bulk and the point of fracture have been registered at the machine. The averages have been calculated well into kgf, being the one Artglass® introducing Targis T TPH Tp = 98,26. The data have been submitted at the statistic analysis. Observed in case that than it is to the resin TPH got considerably under age endurance at the compression while Targis and Artiglass did not they presented difference statistics considerably between they self; the contents of inorganic load influences positively into a resistance of compression.
UNITERMS: composite resin; laboratorial resin; resistance of compression.
