1. 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

2. Avaliação estrutural e biológica de coroas sobre implante confeccionadas com pilares de zircônia em região estética. / Structural and biological crowns on implant abutments made from zirconia region in aesthetics.
This prospective in vivo study has as main objective to evaluate the structural and biological performance of single-tooth implant supported-zirconia restoration in aesthetic region. Sixteen subjects were selected for the placement of thirty-one implants in aesthetic region. For the sample group fifteen single-tooth implants were fabricated. Zirconia abutmen

3. Impact of rehabilitation with metal-ceramic restorations on oral health-related quality of life
As cerâmicas dentais são conhecidas pela excelência em reproduzir artificialmente dentes naturais. Recentemente, devido ao aprimoramento da tecnologia cerâmica, surgiram as restaurações livres de metal. Entretanto, as tradicionais metalocerâmicas ainda preenchem adequadamente os requisitos de alta resistência, longa sobrevida em meio bucal e estétic

4. 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

5. Surface degradation of glass ceramics after exposure to acidulated phosphate fluoride
OBJECTIVE: This study evaluated the surface degradation effect of acidulated phosphate fluoride (APF) gel exposure on the glassy matrix ceramics as a function of time. MATERIAL AND METHODS: Disc-shaped ceramic specimens (N = 120, 10/per ceramic material) were prepared in stainless steel molds (inner diameter: 5 mm, height: 2 mm) using 6 dental ceramics: 3 in

6. Ceramic restoration repair: report of two cases
The esthetic and functional rehabilitation of patients with multiple missing teeth can be performed with several techniques and materials. Ceramic restorations provide reliable masticatory function and good esthetics. However, fracture can occur in some cases due to their brittle behavior. In some cases, the replacement of an extensive prosthesis is a proble

7. 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

8. Estudo da oxidação superficial de ligas odontológicas de Ni-Cr em plasma pulsado para uso em restaurações metalocerâmicas
Metal ceramic restorations matches aesthetic and strength, and in your making occurs an interface oxide layer, wetting resulting and atomic and ionic interactions resulting between metal, oxide and porcelain. However, frequent clinical fails occurs in this restoration type, because lost homogeneous deposition oxide layer and lost interface bond. Thus, in thi

9. Estudo da adesão liga (Ni-Cr)-porcelana em protese dentaria
The main purpose of this s wore was the study of adherence between nickel-chromic um alloys and parcel al n for use in dental restorations. A detailed bibliographic revision was performed and two commercial nickel-chromium alloys was selected. one of them with low concentration of beryllium. Hardness test microstructural analysis of the all oys analysis of t
