[摘要]目的：探究计算机辅助设计/计算机辅助制作（CAD/CAM）瓷贴面在前牙瓷贴面修复中的应用及对变色、敏感、牙龈反应的影响。方法：选取2020年7月-2022年12月于笔者医院就诊116例（148颗患牙）行前牙瓷贴面修复患者为研究对象，按照随机数表法分为传统组（n=58，72颗患牙）和CAD/CAM组（n=58，76颗患牙），比较两组修复后6个月的修复效果，比较修复前、修复后2个月的龈沟液炎性因子指标，比较修复后6个月牙槽骨相关指标、修复后6个月内的并发症发生情况。结果：修复后6个月，CAD/CAM组边缘密合度、颜色匹配、修复体外形、牙龈反应、术后敏感情况A级占比均高于传统组（P＜0.05）；修复后，CAD/CAM组炎症因子水平均低于传统组（P＜0.05）；修复后6个月，CAD/CAM组新骨轮廓、骨密度评分均高于传统组（P＜0.05），牙槽骨吸收量低于传统组（P＜0.05）；CAD/CAM组并发症总发生率低于传统组（P＜0.05）。结论：CAM/CAD瓷贴片应用于前牙瓷贴片修复治疗，可提高修复效果，缓解瓷贴面修复过程中的炎症反应，减少患者的牙龈反应和术后敏感情况，改善新骨轮廓、骨密度及牙槽骨垂直吸收量，且并发症少，值得临床推广应用。

Abstract： Objective" To explore the application of computer aided design/computer aided manufacturing （CAD/CAM） porcelain veneer in anterior teeth porcelain veneer restoration and its influence on discoloration， sensitivity and gingival reaction. Methods" 116 patients （148 affected teeth） who underwent anterior teeth porcelain veneer restoration in the hospital from July 2020 to December 2022 were selected as the study subjects， and were divided into traditional group （n=58， 72 affected teeth） and CAD/CAM group （n=58， 76 affected teeth） according to the random number table method. The restoration effect at 6 months after restoration， gingival creval fluid inflammatory factors before restoration and at 2 months after restoration， alveolar bone related indicators at 6 months after restoration and complications within 6 months after restoration were compared between both groups. Results" At 6 months after restoration， the grade A proportions of marginal fit， color matching， restoration shape， gingival reaction and postoperative sensitivity in CAD/CAM group were higher than those in traditional group （P＜0.05）. The levels of inflammatory factors in CAD/CAM group after restoration were lower than those in traditional group （P＜0.05）. At 6 months after restoration， the scores of new bone contour and bone mineral density were higher in CAD/CAM group than those in traditional group （P＜0.05）， and the alveolar bone absorption volume was lower than that in traditional group （P＜0.05）. The total incidence rate of complications in CAD/CAM group was lower compared with that in traditional group （P＜0.05）. Conclusion" The application of CAM/CAD porcelain veneer in the treatment of patients with anterior teeth porcelain veneer restoration can enhance the restoration effect， relieve the inflammatory response during porcelain veneer restoration process， reduce the gingival reaction and postoperative sensitivity， and improve the new bone contour， bone mineral density and vertical absorption of alveolar bone， with few complications.

前牙外伤、先天畸形、氟斑牙和牙釉质发育不全等原因可导致前牙体积缺损、颜色缺陷或排列异常等牙齿缺陷的发生[1]。完整的牙列在面部的自然形态和美观上占据极其重要的位置，前牙缺陷不仅会影响患者正常咀嚼和语言表达功能，还可能会使患者出现自卑、焦虑等不良情绪，影响患者的心理健康和人际交往能力[2]。……
