摘要： 目的: 探讨椅旁计算机辅助设计/计算机辅助制造（CAD/CAM）冠修复技术在后牙牙体缺损治疗中的疗效及对咀嚼功能的影响。方法: 选择2023年6月—2024年5月收治的98例后牙牙体缺损患者,根据治疗方式不同分为对照组（传统硅橡胶印模冠修复）和试验组（椅旁CAD/CAM冠修复）。比较2组修复效果、修复前后咀嚼效率和咬合力、牙周指标、并发症发生率及患者满意度。采用SPSS 22.0软件包对数据进行统计学分析。结果: 修复后1个月,2组舒适度、边缘密合度、颜色匹配和表面质地相比,差异无统计学意义（P>0.05）;试验组邻面接触、继发龋预防和牙龈状态显著优于对照组（P<0.05）。修复后,试验组咬合力和咀嚼效率显著优于对照组（P<0.05）,牙龈指数、牙菌斑积聚、龈沟出血指数和牙松动度等牙龈健康状况改善水平显著优于对照组（P<0.05）。修复后,2组患者并发症发生率相比无显著差异（P>0.05）。试验组患者修复满意度为96.15%,显著高于对照组的86.96%（P<0.05）。结论: 椅旁CAD/CAM冠修复后牙牙体缺损患者疗效良好,能显著提高修复效果,改善咀嚼效率,有效抑制牙龈炎症与牙菌斑生成,降低牙龈出血与牙松动风险,显著提高患者满意度。

Abstract: PURPOSE: To investigate the effect of chair side computer aided design/computer aided manufacturing (CAD/CAM) crown restoration technique in the treatment of posterior tooth defects and its influence on chewing ability. METHODS: A total of 98 patients with posterior dental defects treated from June 2023 to May 2024 were selected and divided into control group (traditional silicone rubber impression crown repair) and experimental group (chair side CAD/CAM crown repair) according to different treatment methods. The repair effect, masticatory efficiency and bite force before and after treatment, periodontal index, complication rate and patient satisfaction were compared between the two groups. SPSS 22.0 software package was used for statistical analysis of the data. RESULTS: One month after treatment, there was no significant difference in comfort, edge fit, color matching and surface texture between the experimental group and the control group(P>0.05). The experimental group was significantly better than the control group in adjacency contact, secondary caries prevention and gingival status (P<0.05). After treatment,gingival index and plaque buildup, gingival sulcus bleeding index, the degree of gum health improvement of loose tooth in the experimental group were significantly better than in the control group(P<0.05). There was no significant difference in the incidence of complications between the two groups after treatment(P>0.05). Repair satisfaction of the experimental group was 96.15%, which was significantly higher than 86.96% of the control group(P<0.05). CONCLUSIONS: Chair side CAD/CAM crown restoration technology has good application value in the treatment of patients with posterior dental defects, which can significantly improve the repair effect, improve chewing ability, effectively inhibit gingival inflammation and dental plaque generation, reduce the risk of gingival bleeding and tooth loosening, and significantly improve patients' satisfaction.
