Metal-Ceramic Prostheses Overview

A ceramic material used in dentistry, primarily composed of silica and feldspars.

A chemical compound that forms the backbone of dental porcelain, providing strength and structure.

A type of mineral found in porcelain, contributing to its melting point and overall properties.

A visual tool representing the possible compositions of porcelain, showing the proportions of silica, feldspar, and other components.

A process where a mixture of porcelain components is heated to a molten state, then rapidly cooled.

A ground-up powder resulting from the fusing process, ready to be used for making dental restorations.

Substances added to porcelain to create specific shades and colours, mimicking natural teeth.

Substances added to control the melting point, sintering process, and other properties of porcelain.

A process where particles in a powdered material (like frit) bond together at a high temperature, creating a solid structure.

A measure of how much a material expands or contracts with temperature changes. This is important for ensuring a good fit of porcelain restorations.

A type of dental restoration made by fusing porcelain to a metal substructure, providing strength and durability.

The most common term used to describe MC restorations, referring to the process of bonding porcelain to a metal base.

A major advantage of MC restorations, offering excellent resistance to breakage, making them suitable for areas with high chewing forces.

The dark line visible at the gum line of an MC crown, often caused by metal showing through as the gum recedes.

A potential disadvantage of MC restorations, although rare, it can occur with certain metal alloys, particularly those containing nickel.

The use of ceramic materials along the gum line to avoid the aesthetic issue of a metal margin.

A type of ceramic margin used to cover a thin metal edge, providing a more aesthetic appearance.

The process of bonding ceramic to the metal substructure, creating a strong and durable bond.

Materials used for the metal component of MC restorations, requiring specific properties like biocompatibility and strength.

Different categories of ceramic materials used for MC restorations, each offering various properties like strength, aesthetics, and translucency.
