2. Quantitative image of fluorescence of ceramic and resin-cement veneers
Abstract The main of the study was quantify the effect of two ceramics with two underlying resin cements on apparent fluorescence levels. Buccal surfaces of two bovine incisors were ground flat producing one enamel and one dentin substrate. The veneers were fabricated (0.5 and 1.0 mm thickness) using two ceramics (IPSe.max Press and IPSe.max Zirpress, Ivocla

3. Effect of ceramic thickness, grinding, and aging on the mechanical behavior of a polycrystalline zirconia
Abstract Monolithic restorations of Y-TZP have been recommended as a restorative alternative on prosthetic dentistry as it allows a substantial reduction of ceramic thickness, which means a greater preservation of tooth structure. However, the influence of grinding and aging when using a thinner layer of the material is unclear. This investigation aimed to e

4. Avaliação da resistência de união ao microcisalhamento e grau de conversão de cimentos resinosos com a utilização de diferentes protocolos adesivos / Effect of the adhesive protocol on micro shear bond strength and degree of conversion among different resin cement and ceramic
O objetivo deste estudo foi avaliar a resistência de união ao microcisalhamento de três cimentos resinosos (RelyX ARC, RelyX U100 e Panavia F), com diferentes protocolos adesivos estabelecidos para cada cimento e unidos a dois tipos de cerâmica (feldspática - d.SIGN e dissilicato de litio - e.max) através da fotopolimerização transcerâmica. Em adiç

5. Avaliação de parâmetros clínicos relacionados com a longevidade de restaurações cerâmicas livres de metal / Evaluation of clinical parameters to associated with longevity in metal free ceramic restorations
Proporcionar longevidade clínica às restaurações cerâmicas deve ser um dos objetivos principais dos cirurgiões-dentistas ao realizar um tratamento protético. Objetivo: Correlacionar a influência do tratamento interno do substrato cerâmico e do tipo de polimento da superfície cerâmica externa com a efetividade clínica de restaurações com sistema

6. SYNTHESIS AND CERAMIC PROCESSING OF ALUMINA AND ZIRCONIA BASED COMPOSITES INFILTRATED WITH GLASS PHASE FOR DENTAL APPLICATIONS / Síntese e processamento de compósitos á base de alumina e zircônia com infiltração de fase vítrea para aplicações odontológicas
The interest for the use of ceramic materials for dental applications started due to the good aesthetic appearance promoted by the similarity to natural teeth. However, the fragility of traditional ceramics was a limitation for their use in stress conditions. The development of alumina and zirconia based materials, that associate aesthetic results, biocompat

7. Virtual analysis of stresses in human teeth restored with esthetic posts
The use of intra-radicular posts for rebuilding of damaged teeth is a normal practice in contemporary dentistry. However, dental roots restored with posts are subjected to the risk of failure under occlusal loads, particularly in cases of small dentin thickness. This study adopted the finite element analysis to compare the elastic stress distribution in simu

8. Pigmentos nanométricos de alumina dopada com ferro, níquel e manganês / Nanometric pigments of iron, nickel and manganese doped alumina
In the recent years, the necessity of ceramic pigments production with new shades and variable distributions of particle size has increased considerably. The color and size of pigment particles are responsible for important applications in the ceramic industries, resins, cosmetics, dyes, plastics and dentistry materials. In this work, nanometric pigments bas

9. Caracteristicas de superficies, adsorção de proteinas e aderencia bacteriana em diferentes materiais odontologicos / Surface characteristics, proteins adsorption and bacterial adherence on different dental materials
The use of osseointegrated implants for replacing missing teeth is an important alternative in current dentistry. One of the most important conditions, which relates to the future success of implant procedures, is provided by the surface properties of the implant and its prosthetic abutments. Since these components penetrate through the gingival mucosa and a

10. Pilot study of the adhesion between Ni-Cr alloys and ceramics when prosthetic variables were accomplish / Efeito das variáveis laboratoriais protéticas na adesão da porcelana com ligas de níquel-cromo
The metalceramic crowns are usually used in dentistry because they provide a resistant structure due to its metallic base and its aesthetics from the porcelain that recovers this structure. To manufacture these crowns, a series of stages should be accomplished in the prosthetic laboratories, and many variables can influence its success. Changes in these vari

11. Avaliação da resistencia de união entre uma ceramica de alto conteudo cristalino - zirconia - e dois cimentos resinosos, apos diferentes tratamentos de superficie / Evaluation of the bond strength between a high-crystalline content ceramic - zirconia - and two luting systems, after different surface treatments
A dificuldade em se obter valores de união elevados e duradouros entre cimento resinoso e cerâmicas de alto conteúdo cristalino tem limitado o emprego destes materiais. Desta maneira, o objetivo deste estudo foi avaliar a resistência de união entre dois cimentos resinosos e uma cerâmica à base de dióxido de zircônio após diferentes tratamentos supe

12. Ceramic characterization and factography of resin-ceramic adhesive interface after different ceramic surface treatments / Caracterização ceramica e avaliação fractografica da interface adesiva com resina, apos diferentes tratamentos de superficie
This study evaluated the effect of ceramic surface treatments on tensile bond strength (?) and the mode of failure of a resin bonded to two types of ceramics, testing the hypothesis that ? of ceramics to resin is controlled by the ceramic surface treatment. Methods: Ten blocks of each the hot-pressed leucite-based ceramic (E1- IPS Empress) and the two-phase
