1. Influence of the casting material on the dimensional accuracy of dental dies
The purpose of this study was to evaluate the dimensional accuracy of different materials used in the confection of dies. Two stainless steel standard models were confected. One of the models, which was 2 mm larger than the other model, was used to provide a uniform relief for the two-step putty-wash impression technique. Thirty impressions were obtained usi

2. Desajuste marginal e influencia na pre-carga de parafusos e nas tensões induzidas as fixações de pilares metaloplasticos sobre-fundidos / Marginal misfit and influence in the pre-load and the stress-induced setting of the metaloplastic abutments
Castable UCLA abutments are of wide applicability in dental implants, because they allow the manipulation in the laboratory at low cost and individualization of abutments for each patient. However, they show the worse results of marginal adaptation then the fabricated, although these aggregate costs significantly higher. UCLA premachined abutments for castin

3. Avaliação comparativa de propriedades geradas pelos processos de soldagem TIG e brasagem em uma liga odontológica à base de Ni-Cr / Comparative assessment of properties generated by the process of TIG welding and brazing in a Ni-Cr dental alloy
The purpose of this study was to compare, by means of microhardness testing and metallurgical characterization techniques as metallography, optical microscopy, scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS), mechanical and metallurgical properties of welded joints by TIG and brazing methods in a dental alloy based on Ni-Cr (FIT-C

4. Characterization of ceramic powders used in the inCeram systems to fixed dental Prosthesis
InCeram (Vita Zahnfabrik- Germany) is known as a high strength ceramic being used for core crowns and for fixed partial denture frameworks. InCeram system consists of slip-casting technique which is used for to build the framework, which is then pre-sintered obtaining an open-pore microstructure. The material gains its strength by infiltration of the lanthan

5. Análise da técnica de fundição rápida segundo a adaptação cervical de infra-estrutura de liga à base de Ni-Cr e expansões de presa e térmica de quatro revestimentos / Analysis of accelerated casting technique in accordance with marginal adaptation of Ni-Cr crown and curing expansion and thermal expansion of four investments
With the improvement of dental investments for accelerated casting technique, recent studies have demonstrated that the procedure can be considered safe for daily use in the dental laboratory. Thus, cast pieces can be obtained in less time, the prosthetic work as a whole can be speed up and costs are cut with no quality compromise. Even though, there are sti

6. Mechanical properties of commercially pure titanium and Ti-6Al-4V alloys casting in different environments / Propriedades mecânicas do titânio comercialmente puro e da liga Ti-6Al-4V fundidos em diferentes ambientes
Background: Although CP titanium and titanium alloys have been used for medical and dental applications, their high cost has not stimulated their current use. Objective: The purpose of this study was to evaluate the effect of argon purity on the mechanical properties, microstructure and fractography of CP Ti (Grade I) and Ti-6Al- 4V cast alloys. Material and

7. Comparative study of two cp Ti casting methods. / "Estudo comparativo de dois métodos utilizados na fundição de titânio cp"
Along the last decade, several jobs have been highlighting the advantages of titanium and titanium alloys and studied the possible utilization for removable partial dentures (RPD) metal frameworks confection. Although advantages, the cast process still presents problems, limiting the titanium use. The objective of this study was to evaluate the influence of
