中文摘要:
      目的 为评价CEREC椅旁CAD/CAM系统制作的IPS e.max CAD玻璃陶瓷高嵌体应用于根管治疗后牙缺损病例的临床效果。方法 选择42例根管治疗后牙，应用高嵌体的牙体预备方式，采用CEREC椅旁CAD/CAM修复系统和IPS e.max CAD玻璃陶瓷，即刻完成修复体并粘接；修复1年后复查，参照改良修正后的美国公众健康服务标准（US Public Health Service Criteria,USPHS），在修复体边缘染色、边缘继发龋、修复体边缘适合性、修复体崩瓷折裂或脱落、修复体颜色、牙龈健康状况、修复体邻接关系、患者满意度8个方面进行评价。结果 修复体边缘染色C级病例1例，成功率97.6%；边缘继发龋C级病例1例，成功率97.6%；修复体邻接关系欠佳C级病例1例，成功率97.6%；在边缘适合性、修复体崩瓷折裂或脱落、修复体颜色、牙龈健康状况、患者满意方面表现优秀，成功率均为100%。结论 椅旁CAD/CAM系统制作的IPS e.maxCAD高嵌体修复体在短期内可取得良好的修复效果。
英文摘要:
      Objective To evaluate the clinical efficacy of IPS e.max CAD glass-ceramic on-lays fabricated from Cerec chairside CAD/CAM system applied to root canal clinical effects in cases of posterior tooth defects.Methods 42 posterior teeth after root canal treatment were selected,and immediate restorations were completed and bonded using the Cerec chairside CAD/CAM restoration system and IPS E.Max CAD glass-ceramic in an on-lay manner.The restorations were reviewed one year later and evaluated in eight aspects: restoration margin staining,marginal secondary caries,restoration margin fit,restoration chipping or fracture,restoration color,gingival health,restoration adjacent relationship,and patient satisfaction,according to the modified US Public Health Service Criteria (USPHS).Results The margins of the restorations stained grade C in one case,with a success rate of 97.6%;marginal secondary caries grade C in one case,success rate 97.6%;suboptimal adjacency of the res oration grade C in one case,with a success rate of 97.6%;the performance was excellent in terms of marginal fit,restoration chipping or fracture,restoration color,gingival health,and patient satisfaction was excellent,with a success rate of 100%.Conclusion IPS e.max CAD on-lays made with chairside CAD/CAM systems result in excellent repair outcomes in the short term.
