Estudio de los procesos de corrosion de una aleacion metalica de cobre usada en odontologia
(1997-01-01)
Corrosion phenomena in a dental copper-based alloy are experimentally studied using electrochemical techniques. Two heating sources, torch and induction, were used in the casting experiments. In the corrosion essays, the ...
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. ...
Effect of disinfectant agents on dimensional stability of elastomeric impression materials.
(1999-05-01)
STATEMENT OF PROBLEM: Difficulties in sterilizing impressions by traditional methods have led to chemical disinfection as an alternative, and some studies have shown that disinfectants may adversely affect impressions. ...
The Effect of Coating Patterns with Spinel-Based Investment on the Castability and Porosity of Titanium Cast into Three Phosphate-Bonded Investments
(Wiley-Blackwell, 2010-10-01)
Purpose: This study evaluated the effect of pattern coating with spinel-based investment Rematitan Ultra (RU) on the castability and internal porosity of commercially pure (CP) titanium invested into phosphate-bonded ...
Accuracy of Impression Techniques for an Implant-Supported Prosthesis
(Quintessence Publishing Co Inc, 2010-07-01)
Purpose: This in vitro study compared the dimensional accuracy of a stone index and of two impression techniques (squared impression copings and modified squared impression copings) for implant-supported prostheses. Materials ...
Accuracy of impression and pouring techniques for an implant-supported prosthesis
(Quintessence Publishing Co Inc, 2008-03-01)
Purpose: The purpose of this in vitro study was to compare the dimensional accuracy of a stone index and of 3 impression techniques (tapered impression copings, squared impression copings, and squared impression copings ...
A variation on split-cast mounting for complete denture construction
(Mosby, Inc, 2004-04-01)
dThis article describes a variation of the split-cast mounting technique wherein the border of the definitive cast is wrapped with masking tape to form a container for the dental plaster normally used to affix the cast to ...
Comparison of the accuracy for three dental impression techniques and index: An in vitro study
(2013-09-27)
Objectives: This in vitro study compared the dimensional accuracy of stone index (I) and three impression techniques: tapered impression copings (T), squared impression copings (S) and modified squared impression copings ...
Evaluation of a two-step pouring technique for implant-supported prostheses impression
(2010-09-07)
The aim of this study was to evaluate the efficacy of a pouring technique for implant-supported prostheses impressions. A metallic matrix (control group) with two implants positioned at 90 and 65 degrees was fabricated. ...
Fadiga de grampos de retenção em prótese parcial removível. Efeito de ligas, espessuras e técnicas de fusão. Parte II.
(1990-12-01)
The authors tested the T clasp of Roach in three differents proportions among width and thickness: E1-1.7; E2-2.0 and E3-2.3, with a constant length of 15 mm. These clasps were casted with three cobalt-chromium alloys ...
