摘要:: 目的：观察计算机辅助设计（Computer aided design，CAD）/计算机辅助制作（Computer aided manufacturing， CAM ）氧化锆全瓷冠和钴铬合金烤瓷冠在全冠单冠修复患者中的应用效果及其对患者牙周情况的影响。方法：选择2021年8 月-2022年6月保山市人民医院、保山市中医医院、保山德康医院收治的98例全冠单冠修复患者，根据治疗意愿将其分为合金组（48例）和氧化锆组（50例）。合金组采用钴铬合金烤瓷冠进行修复，氧化锆组采用CAD/CAM氧化锆全瓷冠进行修复，两组修复后均随访6个月。统计两组修复后6个月的修复效果、满意度、效果评分、修复体情况及随访期间并发症发生情况，比较两组修复前及修复后6个月牙周情况。结果：修复后6个月，氧化锆组总有效率、边缘密合度、龈缘着色、颜色匹配A级患者占比、总满意率高于合金组（P＜0.05）。与修复前比较，修复后6个月两组牙周探诊深度、牙龈指数均升高，但氧化锆组低于合金组（P＜0.05）；合金组龈沟出血指数、附着丧失升高，且高于氧化锆组（P＜0.05）；修复后6个月，氧化锆组效果评分高于合金组（P＜0.05）。随访期间，氧化锆组总并发症发生率低于合金组（P＜0.05）。结论：与钴铬合金烤瓷冠相比，采用CAD/CAM氧化锆全瓷冠对全冠单冠修复患者进行治疗可有效改善患者牙周健康状况，修复体情况更好，同时可有效提高患者修复满意度，降低并发症的发生，具有较好的修复效果。

Abstract:: Objective To investigate the application effect of CAD/CAM zirconia porcelain crown and cobalt-chromium porcelain crown in patients with full crown and single crown restoration and their eff ects on patients’ periodontal condition. Methods From August 2021 to June 2022, 98 patients with total crown restoration admitted to Baoshan People’s Hospital, Baoshan Hospital of Traditional Chinese Medicine and Baoshan Dekang Hospital were divided into the alloy group (48 cases) and the zirconia group (50 cases) according to the patients’ treatment intention. The alloy group was repaired with cobalt chrome porcelain crown, and the zirconia group was repaired with CAD/CAM zirconia all-porcelain crown. Both groups were followed up for 6 months. The repair eff ect, the score of eff ect, the condition of the repair body, satisfaction 6 months after repair and the incidence of complications during the follow-up were counted in the two groups. The pericrescent condition of the two groups were compared before and 6 months after the repair. Results 6 months after repair, the total eff ective rate, the percentage of patients with grade A, marginal close, gingival margin coloring and color matching and the verall satisfaction rate of the zirconia group was higher than that of the alloy group (P ＜0.05). The periodontal probe depth and gingival index of the two groups increased 6 months after repair compared with before repair, but the zirconia group was lower than the alloy group (P＜0.05). The gingival crevicular bleeding index and attachment loss in alloy group were higher than those in zirconia group (P＜0.05). 6 months after repair, the score of eff ect of zirconia group was higher than that of alloy group (P ＜0.05). During the follow-up period, the total complication rate in the zirconia group was lower than that in the alloy group (P＜0.05). Conclusion Compared with cobalt-chromium porcelain crown, CAD/CAM zirconia porcelain crown could eff ectively improve the periodontal health of patients with full-crown single-crown restoration, and the condition of the prosthesis is better. At the same time, it could eff ectively improve the satisfaction of patients with restoration, reduce the occurrence of complications, and had a better repair eff ect.
