口腔科常用的牙齿充填材料有银汞合金、丙烯酸脂类自凝塑胶、矽粘固粉、磷酸锌粘固份与 EB 型复合树脂。这几种充填材料均各有其优点,如在体积收缩、热膨胀系数,抗压强度、耐磨等方面,复合树脂比自凝树胶优越。但在物理性能和机械性能方面,复合树脂又次于银汞合金。由于复合树脂的颜色与牙齿色泽相同,又不溶于唾液,故用于前牙充填比矽粘固粉和银汞合金都理想。根据有限的临床实践,证实 EB 型复合树脂在 Stomatology commonly used dental filling materials are silver amalgam, acrylic self-curing plastic, silicone cement, zinc phosphate cement and EB-based adhesive composite resin. These types of filling materials have their own advantages, such as volume shrinkage, thermal expansion coefficient, compressive strength, wear resistance, composite resin than self-setting gum superiority. However, the composite resin is inferior to the amalgam in terms of physical properties and mechanical properties. As the composite resin color and tooth color the same, but also does not dissolve in saliva, it is more suitable for anterior teeth than the silicon cement and silver amalgam filling ideal. According to the limited clinical practice, confirmed EB-type composite resin in
