Castability 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 کاملBiocompatibility of a titanium dioxide-coating method for denture base acrylic resin.
OBJECTIVES Ease of denture cleaning is of paramount importance in geriatric patients and those with limited dexterity. We have previously investigated methods of coating dentures with titanium dioxide (TiO2 ) and reported the effects (self-cleaning and antibacterial) of such treatments in in vitro studies. This study was to verify the biocompatibility of a TiO2 -coated acrylic resin produced by...
متن کاملEffect of Stone Cast Type on Complete Denture Base Adaptation
Introduction: Few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. The purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. Methods: Using sixty fully replicated master casts obtained by duplicating a metal die represent...
متن کاملColor and gloss evaluation of titanium dioxide coating for acrylic resin denture base.
PURPOSE We examined the clinical appearance (color, gloss, and surface roughness) of TiO(2) coating on polymethyl methacrylate (PMMA) resin dentures. METHODS A spraying method, using air brushes, was used to generate thin uniform TiO(2) coating. PMMA resin, primer-coated PMMA, and TiO(2)-coated PMMA (with primer) specimens were compared. RESULTS The Commission Internationale de l'Eclairage ...
متن کاملOptimization of the chemical milling of investment cast titanium alloys
Investment casting is a popular casting technique for manufacturing of several titanium alloy components dedicated to different industrial applications, as aerospace and automotive. This manufacturing process could be an economic net-shape technology, since the investment casting allows obtaining complex shapes, accurate geometries and reduced thicknesses. However, the reactions between titaniu...
