2. Análisis de la forma de onda de señales de Emisión Acústica producida en ensayos de interfaces ceramo-metálicas
ABSTRACT The study of ceramic-metal interface is of special importance in odontology area by the current demand about dental prostheses, so it is very important to be more and more similar to natural teeth and with a long service life. With the aim of assessing in detail the behavior of ceramic-metal interface used in dental restorations systems, in this wor

3. Effect of the Cooling Rate on the Properties of Veneer Porcelain for Zirconia Dental Prosthesis
To solve chipping of veneer porcelain in zirconia dental prosthesis it has been studied different cooling rates in firing schedules to control residual stresses generated by differences in thermal properties between the ceramics. However, cooling rates may affect the porcelain, irrespectively of interaction with zirconia. This study analyzed the effect of co

5. Sobrevida de prótese parcial fixa posterior em zircônia: revisão sistemática de estudos clínicos com até 7 anos de acompanhamento
Resumo A cerâmica odontológica tem sofrido modificações na composição visando melhorar sua resistência em resistir às forças mastigatórias fisiológicas na região posterior da boca. O objetivo deste trabalho foi avaliar o comportamento clínico de próteses parciais fixas posteriores (PPFs) em zircônia a partir de estudos clínicos prospectivos d

6. Shear bond strength of ceramic brackets after different pre-treatments in porcelain surface
AIM: To evaluate the bond strength of brackets bonded after different surface treatments on two dental ceramics. METHODS: One hundred and twenty discs 5 mm thick and 7 mm diameter of two ceramic types were made and randomly divided in 8 groups. Groups 1, 3, 5, and 7 used Eris ceramic and groups 2, 4, 6, and 8 used d.Sign ceramic. The ceramic surfaces were t

7. Production and characterization of colored feldspathic enamel for dental application
In this work we synthesized pigments capable of developing dental shades when mixed with dental porcelain and fired at appropriate temperatures. TiO2-xCeO2 pigments (x = 2, 6, 10, 13 and 18 mol%) were synthesized by the Pechini method. Characterization by thermal analysis revealed the stability of the material at temperatures up to 1200 ºC. X-ray diffractio

8. Evaluation of the adaptation of zirconia-based fixed partial dentures using micro-CT technology
The objective of the study was to measure the marginal and internal fit of zirconia-based all-ceramic three-unit fixed partial dentures (FPDs) (Y-TZP - LAVA, 3M-ESPE), using a novel methodology based on micro-computed tomography (micro-CT) technology. Stainless steel models of prepared abutments were fabricated to design FPDs. Ten frameworks were produced wi

10. Flexural strength of fluorapatite-leucite and fuorapatite porcelains exposed to erosive agents in cyclic immersion
OBJECTIVE: The aim of this study was to evaluate the fexural strength of two porcelain materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents. MATERIAL AND METHODS: One hundred and twenty bar-shaped specimens were made from each of fuorapatite-leucite porcelain (IPS d.SIGN) and fuorapatite porcelain (IPS e.max Ceram) and divided into 8 groups o

11. Analysis of polymerization time on abrasive wear of dental resins
An evaluation was made of the abrasive wear of six composite thermofixed dental resins subjected to different polymerization times. The method of evaluation was based on sharpness measurements to quantify the abrasive wear resistance of the resins. To this end, a test bench was built, consisting of a rotating porcelain cylinder that wears out a resin-coated

12. Effects of different polishing techniques on the surface roughness of dental porcelains
OBJECTIVE: The purpose of this study was to evaluate the effects of different polishing techniques on the surface roughness of dental porcelains. MATERIAL AND METHODS: Fifty-five cylindirical specimens (15x2 mm) were prepared for each feldspathic (Vita VMK 95, Ceramco III) and low-fusing dental porcelain (Matchmaker). Fifty-five specimens of machinable felds
