Veneer material is currently divided into plastic, metal porcelain, all porcelain, etc., first of all, metal porcelain and divided into nickel-chromium alloy porcelain teeth, cobalt-chromium alloy porcelain teeth, titanium porcelain teeth, pure titanium porcelain teeth, precious metal porcelain teeth, etc., veneer is divided into active restoration and fixed restoration, active restoration has two parts consisting of teeth and abutments. Next dental materials can choose plastic, porcelain, resin, plastic is not wear-resistant, easy to adsorb bacteria, easy discoloration, etc., so the current use of less; porcelain teeth wear-resistant, good gloss, not easy to be stained, but not as good as plastic teeth and abutment bonding; resin teeth advantages and disadvantages between plastic teeth and porcelain teeth, abutment plastic abutment and metal abutment, metal abutment than plastic abutment strength, thin thickness, good comfort, metal in pure titanium Relatively better, so the movable denture choose pure titanium brackets and wear-resistant resin teeth. Then the fixed denture is divided into metal teeth, porcelain teeth, all-porcelain teeth, all-porcelain teeth have better biological stability and color closer to the real teeth, will not cause black staining of the gum edge, so the fixed restoration of all-porcelain teeth better.
