摘　　要：目的:应用掺钕钇铝石榴石(neodymium doped yttrium aluminum garnet,Nd:YAG)激光脱色与计算机辅助设计/计算机辅助制造(computer aided design/computer aided manufacturing,CAD/CAM)全瓷冠美学修复并观察其临床疗效。方法:选择右上前牙死髓牙患者1例,经完善根管治疗后牙体变色,经激光脱色后2周复诊,测色仪检测牙体颜色恢复正常。应用CAD/CAM椅旁快速制作二矽酸锂修复体,按照改良的美国公共卫生署(United States Public Health Service,USPHS)标准进行修复后6个月的临床疗效评价。结果:修复后6个月,修复体无脱落,折断、劈裂、变色等不良现象,临床指标均达到A级指标。结论:Nd:YAG激光对死髓牙脱色,并行CAD/CAM全瓷冠美学修复,短期内可获得良好的临床效果。Objective： To observe the clinical effects on discolored tooth through neodymium doped yttrium aluminum garnet（ Nd： YAG） laser decoloration and esthetic restoration with CAD / CAM all ceramic crown. Methods： The clinical case was one patient with one right central incisor discolored tooth after root canal therapy,which restored with all ceramic crown by CAD / CAM after Nd： YAG laser decoloration. The clinical effects were assessed after 6 months according to modified USPHS standard. Results： There were no undesirable effects such as fall off,fracture,and cleavage occurred with 6 months followed-up,and the clinical indexes had up to A class. Conclusion： Better clinical effect can be achieved in Nd： YAG laser decoloration and esthetic restoration with CAD / CAM all ceramic crown,but the long-term follow-up result still had to be further observed.
