GC GRADIA DIRECT光固化复合树脂修复切缘缺损疗效观察

目的：应用GC GRADIA DIRECT光固化复合树脂修复切缘缺损观察病例的疗效。方法：将189颗切缘缺损牙齿应用GC GRADIA DIRECT光固化复合树脂进行修复,并经过2年的随访观察。结果：应用GC GRADIA DIRECT光固化复合树脂进行修复切缘缺损成功率为97.88%。结论：GC GRADIA DIRECT光固化纳米混合型复合树脂模仿自然牙体散射和漫反射的光学原理,实现＂隐形＂修复（变色龙效果）。同时具有良好的粘结性能,高抗压强度,良好光泽度和抛光性,长期稳定性强等特点。因此GC GRADIA DIRECT光固化复合树脂是修复前牙各类牙体缺损的理想材料。

Clinical effects of GC GRADIA DIREC light-curing composite resins for restoring the incisal edge defects

Objective To evaluate clinical effects of GC incisal edge defects. Methods 189 teeth with incisal GRADIA DIREC light-curing composite resins for restoring the edge defects were restored with applying GC GRADIA DIREC light-curing composite resins. And curial effects were evaluated by observing all the cases two years later after the treatment. Results The success rate of GC GRADIA DIREC light-curing composite resins for incisal edge defects is 97.88%. Conclusion GC GRADIA DIREC light-curing nano-hybrid composite resins can simulate the optics principle of scattering and diffuse reflection of the natural teeth and obtain ＂invisible＂ restoration （Chameleon effects）.They also provide good bond behavior,high compressive Strength,favorable gloss and polishing,and excellent long-term stability. GC GRADIA DIREC light-curing composite resins are ideal materials for restorations of various incisor defects.
