Study on translucency of tooth-colored restorative materials

用角形光度计测定了不同不透明树脂的透射光分布。不透明树脂比常规遮光树脂复合材料透光分布更宽，不透明度更高。临床上，不透明树脂应用于因美观原因想要更换金属修复体的患者。在金属修复体表面涂覆不透明树脂。不透明树脂也适用于变色的牙齿。这些修复体对牙齿的侵入性和保守性较小。大多数患者对这些治疗感到满意。

Transmitted light distribution of various opaque resin was evaluated with a gonio-photometer. Opaque resin showed wider transmitted light distribution and more opacity than regular-shade restorative resin composite. Clinically, opaque resin was applied to the patients who wanted to replace their metal restorations for esthetic reason. Opaque resin was coated on the surface of metal restoration. Opaque resin was also applied for the discolored teeth. These restorations were less invasive and conservative for the teeth. Most of the patients were satisfied with these treatment.
