(1).Silver amalgam filling material: wear resistance, compressive strength, stable performance, no stimulation of pulp and other characteristics, but because it was metallic colors, and natural tooth color vary greatly in appearance and poor, it is generally used in the dental cavity filling. PS: the presence of a small number of patients allergic to amalgam case (headache, dizziness, blurred vision, etc.), the need to pay attention
(2)Composite resin filling materials : currently ideal tooth-colored restorative material , the most prominent advantage is that it has another appearance high mechanical strength to withstand high mastication forces brittle quality tough and difficult to break , but the presence of a polymerization shrinkage , poor wear resistance insufficient , and the pulp has a certain period of time after the filling stimulation (mainly no bottom to protect vital teeth ) , usually used for restoration and repair of non- ecclesial surface of posterior teeth before
(3)Glass incomer cement filling material : pulp irritation of pressure , good adhesive properties , closed good performance, secondary caries prevention , aesthetics amalgam good but less than the composite resin poor characteristics , but mild dissolved in saliva , the mechanical strength is better than two, usually used for anterior and posterior cavity and non- deciduous ecclesial repair of all types of hole shape for cavities resulting cavity is particularly applicable under normal circumstances .
