[摘 要]目的 比较部分全瓷贴面、树脂充填两种修复方法在上前牙小范围切角缺损修复中的应用效果。方法 选取我院2020年7月-2023年1月收治的60例上颌前牙小范围切角缺损且没有损伤牙髓的患者为研究对象，采用随机数字表法分为对照组和观察组，各30例。对照组接受纳米树脂填充治疗，观察组接受部分全瓷贴面治疗，比较两组临床疗效及并发症发生情况。 结果 观察组治疗总有效率为93.33%，高于对照组的70.00%，差异有统计学意义（P<0.05）；观察组并发症发生率为6.67%，低于对照组的33.33%，差异有统计学意义（P<0.05）。结论 在严格筛选适应证的条件下，上颌前牙小范围切角缺损的修复治疗中应用部分全瓷贴面可获得较为理想的修复治疗效果，且并发症相对较少，值得临床应用。

[Abstract]Objective To compare the application effects of partial all-ceramic veneer and resin filling in the repair of small-scale incisal angle defect of upper anterior teeth. Methods From July 2020 to January 2023， 60 patients with small-scale incisal angle defect of maxillary anterior teeth and no damage to pulp were selected as the research objects. They were divided into control group and observation group by random number table method， with 30 patients in each group. The control group received nano-resin filling treatment， and the observation group received partial all-ceramic veneer treatment. The clinical efficacy and complications of the two groups were compared. Results The total effective rate of treatment in the observation group was 93.33%， which was higher than 70.00% in the control group， and the difference was statistically significant （P<0.05）. The incidence of complications in the observation group was 6.67%， which was lower than 33.33% in the control group， and the difference was statistically significant（P<0.05）. Conclusion Under the condition of strict screening of indications， the application of partial all-ceramic veneer in the repair and treatment of small-scale incisal angle defect of maxillary anterior teeth can obtain ideal repair and treatment effect， and the complications are relatively few， which is worthy of clinical application.

牙齒的形态和颜色的变化对人的整体形象有重要影响，而上前牙切角缺损是引起牙齿形态和颜色变化常见的原因之一。患者发生上前牙切角发生缺损时不仅妨碍其正常发音和咀嚼功能，部分患者还会因为外观的损害而感到焦虑不安，对其心理健康产生负面影响[1，2]。口腔颌面美观是口腔健康相关生活质量（oral health-related quality of life，OHRQOL）的重要部分[3]。鉴于此，临床进行牙齿修复时，不应仅仅集中于恢复牙齿的生理功能，还需充分考虑修复的美观性[4]。此外，随着现代社会对于美观性和微创治疗需求的不断提升，许多患者趋向于寻求在最小限度磨损牙齿的前提下，获得既美观又持久的修复效果。关于牙齿修复的方案选择，常见的治疗方法包括树脂填充、全瓷贴面以及部分全瓷贴面。纳米树脂修复具有操作方便、颜色美观和粘接性较强等优点，然而治疗后可能较容易发生继发性龋病、粘接剂老化导致充填物脱落及牙髓产生不良反应等情况，远期效果欠佳[5]。……
