Objetivo: Avaliar a longevidade clínica, discrepância marginal (DM) e discrepância
interna (DI) de coroas totais monolíticas posteriores confeccionadas de dois materiais
cerâmicos em CAD/CAM (zircônia monolítica ultratranslúcida e dissilicato de lítio), bem
como o impacto da reabilitação oral ...

The crown lengthening is indicated for aesthetic purposes, exposure of subgingival caries, crown fractures or a combination of these, which can be characterized as aesthetic or functional, related to restorative indications, and restoration of biological width. Several factors need to be evaluated in the...
Objective: The aim of this study was to evaluate the marginal gap of frameworks produced using the CAD-CAM system, from zirconia and lithium disilicate blocks, adapted to a tooth preparation and a gypsum die. Material and Methods: For this study, a human first molar tooth was used as a ...
Objective: This in vitro study evaluated the translucency and polymerization light transmission of zirconia discs, produced from different generations of dental zirconia materials and with a consideration of varying thicknesses. Material and Methods: Disc-shaped specimens (0.5mm, 1.0mm, 1.5mm, 2.0mm, and...
Objective:This study evaluated the effect of immediate dentin sealing on the marginal adaptation of lithium disilicate overlays with three different types of resin-luting agents: preheated composite, dual-cure adhesive resin, and flowable composite. Materials and Methods: Forty-eight maxillary first...
The aim of this study was to investigate the influence of the quantity and positioning of feldspathic ceramic specimens inside the furnace on their flexural strength and translucency. The tested hypotheses were that the arrangement of specimens in the furnance would not influence 1) the translucency or 2...
O objetivo do presente estudo foi avaliar a indicação do uso das cerâmicas feldspáticas em dentes posteriores, pela técnica CAD/CAM (Computer-aided design [CAD] e computer-aided manufacturing [CAM]) chairside, em uma unidade de alta demanda, por meio de uma revisão de literatura. Uma pesquisa avan�...
ABSTRACT: Nowadays, maxillary midline diastema (MMD) can be treated with different multidisciplinary approaches. When restorative dentistry is needed, glass-matrix ceramic materials is one of the best choices, since they present good optical behavior and high survival rates in the anterior dentition. To ...
O objetivo desse trabalho foi avaliar a influência de diferentes graus de opacidade e espessuras do dissilicato de lítio no grau de conversão de dois cimentos resinosos e na resistência de união dos mesmos à cerâmica. Duzentos e quarenta amostras cerâmicas de dissilicato de lítio (6x6 mm) foram ...
ABSTRACT Objective To assess the effects of coloring beverages on the color stability of two types of hybrid ceramics with different surface treatments. Material and Methods 180 specimens of two hybrid ceramics (Vita Enamic and Mazic Duro) and a feldspathic ceramic (Vita Mark II) were prepared (n=60 in...
