摘要： 目的:考察热压铸瓷牙合面瓷贴面在后牙缺损的短期临床效果。方法:对28例患者的35个后牙牙体缺损,包括18个重度磨耗活髓后牙和17个根管治疗术后牙合面牙体缺损后牙,采用热压铸瓷牙合面瓷贴面修复。根据改良USPHS修复体评价标准,分别于修复后完成当日和1、6、12、24、36个月对牙合面瓷贴面进行随访复查,结果采用χ2检验分析。结果:后牙热压铸瓷牙合面瓷贴面的修复体外形、边缘适合性、牙龈状况、继发龋和邻面接触点在观察期间表现良好。有2例下颌前磨牙牙合面瓷贴面在粘结2年后出现脱落,χ2检验分析修复体固位的A级成功率在6个时间节点间差异无统计学意义。36个月内各项评估A级成功率在90%以上。结论:热压铸瓷牙合面瓷贴面用于重度磨耗活髓后牙与根管治疗术后牙合面牙体缺损后牙短期修复效果良好,为后牙牙体缺损微创修复提供了一种方式,但其远期效果仍有待进一步观察。

Abstract: Objective: To observe and evaluate 3-year clinical performance of IPS e.max Press occlusal veneer for single posterior tooth. Methods: 35 posterior teeth of 28 patients (18 with severe tooth wear and 17 with occlusal defect after root canal treatment) were restored with IPS e.max Press occlusal veneer. The restorations were evaluated by Modified US Public Health Service criteria at baseline in month 1, 6, 12, 24 and 36. The chi-square test was used to analyze the survival rate. Results: The anatomical form, marginal adaption, soft tissue health, secondary caries and proximal contact points of the restorations were good during 36 months. 2 mandibular premolars’ occlusal veneers were lost at 24 months. But chi-square test showed no significant difference between different time points. The percentage of success rate with A score was above 90%. Conclusion: The occlusal veneer fabricated by IPS e.max Press for the restoration of posterior tooth with severe wear or occlusal defect after root canal treatment demonstrated satisfactory clinical performance during 36 months. Minimally invasive dentistry was a new method for the restoration of posterior tooth defect. Further study was still needed for its long-term outcome.
