Restoration

Amalgams: One of the oldest continually used facing materials. The most researched material available with modern improvements. Can function well in the right situation. Drawbacks can include marginal breakdown, fracture, pressure on enamel and poor cover.

Composite (Bonded Porcelain): A newer material continually improved. Since the 1970's, pluses include bonding to increase strength, good color and low conductivity. Problems include lower abrasion resistance, more difficult placement which results in higher fees.

Cast Gold: Full crown inlays and on-lays, the oldest continually used material by far. Used in ancient Egypt. The strongest and longest lasting. The only drawback seems to be color. It is the most biocompatible material.

Fired Porcelain: Inlays and on-lays continuing technological improvements with one of the worlds oldest man made materials. Advantages include strength, low conductivity and bondability. Drawbacks can be abrasive against opposing natural teeth and brittleness.

Porcelain Fused to Noble Metal (Gold Pladium and Platinum): Technology originally developed in the late 1940's has the advantage of porcelain and metal. Newer versions containing high yellow gold content offer better color and translucency. Drawbacks include color and softer understructure precluding use in bridgework.
