Castable glass ceramics for veneer restorations

The Journal of Prosthetic Dentistry, 1992
Porcelain veneer restorations are the usual technique chosen for the placement of esthetic veneer restorations. Cast glass ceramic veneers exhibit properties that make them extremely useful for this dental application. They have a hardness, abrasion resistance, coefficient of thermal expansion, and translucency similar to that of enamel. The use of the

Glass-ionomer dental restoratives

Progress in Polymer Science, 2001
Abstract The history and chemistry of conventional (chemically cured) and visible light-cured (VLC) glass polyalkeonates (glass-ionomers) is reviewed. The synthesis of new acrylic acid copolymers, containing amino acid residues, derived from amino acid based acrylamides or methacrylmides, and N-vinylpyrrolidone, is described, along with the use of ...

Dental Caries under Glass Ionomer Restorations

Journal of Public Health Dentistry, 1996
AbstractThe Atraumatic Restorative Treatment (ART) technique has two potential limitations. Because only hand instruments are used, dental caries can be left during cavity preparation. Beyond this limitation, the glass ionomer filling material currently used has some unfavorable mechanical properties with respect to its strength, wear resistance, and ...

Virtual restoration of fragmented glass plate photographs

Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004
In this paper we address the problem of restoration of fragmented glass plate photographs. We propose an algorithm based on the roto-translation of the fragments. A preprocessing adjustment in the contour combined with final interpolation is necessary to avoid artifacts.

The creep behavior of glass-ionomer restorative materials

Dental Materials, 1991
The creep of microspecimens of five glass-ionomer filling materials and one glass-ionomer-cermet cement was studied by means of a torsional creep apparatus. The glass-ionomer specimens were aged one week and conditioned in 37 degrees C water. Shear stress of 2.47 x 10(-4) N.m was maintained for three h, and recovery was followed for 50 h.

Glass ionomer restoratives.

Journal (Indiana Dental Association), 1994
This article gives an overview of the new hybrid (light-cured) glass ionomers, which are a combination of auto-cured glass ionomer and light-cured composite resin. The characteristics of these materials and the different brands available are discussed. A clinical technique for restoration of cervical lesions with these materials is presented.

Reinforcement of conventional glass-ionomer restorative material with short glass fibers

Journal of the Mechanical Behavior of Biomedical Materials, 2009
This study investigated the strengthening effect of glass fibers when added to conventional glass-ionomer restorative material. Glass fibers were incorporated into glass-ionomer powder in 3 wt% and 5 wt%. The fibers used had 1 mm length and 10 microm thickness.

Glass ionomer (polyalkenoate) cement restorations.

Current opinion in dentistry, 1992
Glass ionomer cements are recognized for their properties of reliable adhesion to tooth structure and fluoride release. The introduction of light-cured base and liner glass ionomer cements has overcome some of the disadvantages of self-cured materials.
