瓷睿刻高嵌体修复根管治疗后牙体缺损的临床观察

Clinical observation of carved porcelain farce ceramic onlay in repairing tooth defect after root canal therapy

目的观察瓷睿刻(CEREC)玻璃陶瓷高嵌体应用于根管治疗(RCT)后牙体缺损修复的临床效果,为临床提供参考。方法对2015年4月~2016年3月就诊于山西医科大学口腔医院综合科的62例经过完善RCT的70颗后牙行高嵌体修复。分别于修复术后3、6、12个月复诊,了解患牙临床使用情况并用美国公共卫生服务(USPHS)修正标准评价修复体的质量。结果 62例除1例(1颗)失联外;其余61例(69颗患牙)均按要求复诊,随访时间3~15个月,随访率为98.39%(61/62)。复诊病例中有1例(1颗患牙:左下第二磨牙)于修复后3个月出现修复体脱落,其余患者对修复体的临床使用情况均较为满意,患者满意度为98.36%(60/61)。69颗患牙中有1颗3个月复诊时出现修复体脱落,其余68颗全部达到A级和B级,修复成功率为98.55%(68/69)。结论 CEREC高嵌体修复RCT后大面积缺损的后牙,能获得较高的修复质量且患者满意度高,值得临床推广应用。

Objective To observe the clinical effect of glass ceramic onlay created with carved porcelain farce（CEREC）system in repairing tooth defect after root canal therapy（RCT）,to provide referance for clinic.Methods 70 teeth of 62 cases of patients,who visited to Department of General of Shanxi Medical University from April 2015 to March 2016,were repaired by glass ceramic onlay by using CEREC system after perfect RCT.In 3,6,12 months of follow-up after repairing,clinical use of teeth were understood and the quality of fixed restorations was evaluated by the United States Public Health Service（USPHS） modified standards.Results One case was out of contact,other 61 patients（69 teeth） returned on time,3-15 months of follow-up,follow-up rate was 98.39%（61/62）.The prosthesis of 1 case（1 affected tooth：left lower the second molar） of follow-up cases 3 months after restoration falled off,the rest of the patients with the clinical usage of restoration were relatively satisfied,satisfaction rate of patients was 98.36%（60/61）.The prosthesis of 1tooth falled off 3 months after restoration,the others for 68 teeth were all graded A and B,success rate of restoration was98.55%（68/69）.Conclusion Clinical effect of glass ceramic onlay by using CEREC system repairing tooth defect after RCT is significant.It is deserving of clinical popularity and application.
