Effect of phosphate-bonded investments on titanium reaction layer and crown fit
(2010-04-01)
This study analyzed the reaction layer and measured the marginal crown fit of cast titanium applied to different phosphate-bonded investments, prepared under the following conditions (liquid concentration/casting temperature): ...
Estudo das alterações lineares na região cervical de blocos M.O.D. fundidos em liga de cobre alumínio, segundo as técnicas de expansão higroscópica e térmica.
(1990-07-01)
The authors studied linear alterations processed on copper-aluminum casten MOD blocks, obtained from two expansion techniques (termic and hygroscopic by immersion). UNITERMS: Investment expansion. Thermic expansion. ...
Metallurgical evaluation of a copper-based alloy for dental castings.
(1991-08-01)
The present study was designed to evaluate the metallurgical properties of an experimental, low-cost copper-zinc-aluminum-nickel alloy for dental castings. Some specimens were subjected to heat treatment after induction ...
Marginal fit of nickel-chromium copings before and after internal adjustments with duplicated stone dies and disclosing agent.
(2000-06-01)
STATEMENT OF PROBLEM: Despite careful procedures, master stone dies may be damaged during laboratory procedures. The dentist routinely adjusts castings because the marginal fit of casting is not as accurate as on the dies. ...
Comparison of impression techniques and double pouring by dental cast's accuracy. Preliminary clinical-lab trial
(2019-01-01)
Aim: This study compared impression techniques and double pouring by means of cast's accuracy. Methods: For each patient (n=10), impressions from right maxillary canine to first molar were made with acrylic resin trays and ...
Efeito das técnicas de fusão sobre a fluidez de ligas do sistema cobre-alumínio.
(1990-12-01)
It was evaluated the castability of four copper-aluminium alloy according the melting casting method used. The specimens were made using polyester mesh screen, with 11 x 11 filaments of 0.26 mm thick, fixed along of two ...
Rugosidade superficial de ligas com alto conteúdo de cobre, em função do aquecimento acima da temperatura de fusão.
(1990-12-01)
Being the surface roughness a fundamental property in the fit of the castings, it was determined the roughness of 5 high-copper casting alloys, according to the heating over their melting temperature. That way, the specimens ...
Effect of phosphate-bonded investments on titanium reaction layer and crown fit
(Sociedade Brasileira de Pesquisa Odontológica, 2010)
This study analyzed the reaction layer and measured the marginal crown fit of cast titanium applied to different phosphate-bonded investments, prepared under the following conditions (liquid concentration/casting temperature): ...
Retention strength of cobalt-chromium vs nickel-chromium titanium vs Cp titanium in a cast framework association of removable partial overdenture
(2011-05-01)
Aim: There is little information considering the framework association between cast clasps and attachments. The aim of this study was to evaluate the retention strength of frameworks match circumferential clasps and extra ...
