Lithium Disilicate Glass-Ceramic
ceramic on light transmission of light-emitting diode (LED) and quartz-tungsten-halogen units (QTH) were evaluated. Ceramic IPS e.max CAD shades A1, A2, A3, A3.5, high (HT) and low (LT) translucency were cut (1, 2, 3, 4 and 5 mm). Light sources emission spectra were determined. Light intensity incident and transmitted through each ceramic sample was measured to determine light transmission perc...
متن کاملVeneer fracture in implant-supported metal-ceramic restorations. Part I: Overall success rate and impact of occlusal guidance.
PURPOSE The aims of the presented study were to define the fracture rate of implant-supported metal-ceramic restorations delivered in private practice, and to identify if a restoration's contact during eccentric mandible movements has any influence on ceramic fracture rates. MATERIAL AND METHODS Within the period from 2005 to 2008, 251 patients, namely 105 men (42%) and 146 women (58%), recei...
متن کاملMarginal Adaptation and Fracture Resistance of Resin Nano-Ceramic and Zirconium Dioxide All Ceramic Restorations
Marginal adaptation is one of most important criteria for long term clinical success of dental restorations [1]. The presence of marginal discrepancies exposes the luting agent to the oral environment. The larger the marginal discrepancy and the subsequent exposure of the dental luting agent to oral fluids, the more rapid the rate of cement dissolution and microleakage [2]. These marginal irreg...
متن کاملInfluence of low concentration acid treatment on lithium disilicate core/veneer ceramic bond strength
OBJECTIVE This study evaluated the influence of low concentration acid treatment on the shear bond strength between lithium disilicate (LD) infrastructure and veneering porcelain. The surface morphology characteristic after this acid treatment was also examined. STUDY DESIGN LD reinforced ceramic cylinders (n=10) (IPS e.max Press, Ivoclar-Vivadent, Schaan, Liechtenstein) were treated (LD-trea...
متن کاملInfluence of preparation design and ceramic thicknesses on fracture resistance and failure modes of premolar partial coverage restorations.
STATEMENT OF PROBLEM Preparation designs and ceramic thicknesses are key factors for the long-term success of minimally invasive premolar partial coverage restorations. However, only limited information is presently available on this topic. PURPOSE The purpose of this in vitro study was to evaluate the fracture resistance and failure modes of ceramic premolar partial coverage restorations wit...
