摘　　要：目的:观察计算机辅助设计(CAD)/计算机辅助制造(CAM)复合树脂高嵌体与超瓷树脂嵌体用于磨牙根管治疗后大面积缺损修复的临床效果。方法:选取笔者医院2020年1月-2022年1月收治的97例磨牙根管治疗后大面积缺损患者作为研究对象。将患者随机化分为对照组(n=48)和观察组(n=49)。观察组采用超瓷树脂嵌体修复,对照组采用CAD/CAM复合树脂高嵌体修复,比较两组修复后6个月、12个月的修复效果、龈沟液炎症介质水平、患者对修复体外观满意度及并发症发生情况。结果:6个月后复诊,观察组患者脱落、边缘密合性、牙体完整性三方面I级占比均高于对照组(P<0.05),Ⅱ级、Ⅲ级占比均略低于对照组(P<0.05);观察组患者在外观满意度方面I级占比均略高于同期对照组(P<0.05),Ⅱ级、Ⅲ级占比均略低于同期对照组(P<0.05);观察组龈沟液体中肿瘤坏死因子(TNF-α)、白介素(IL-6)均略低于对照组(P<0.05);观察组继发龋、食物镶嵌两方面I级占比均略高于对照组(P<0.05),Ⅱ级、Ⅲ级占比均略低于对照组(P<0.05)。12个月后复诊,观察组患者脱落、边缘密合性、牙体完整性三方面I级占比均明显高于对照组(P<0.05),Ⅱ级、Ⅲ级占比均明显低于对照组(P<0.05);观察组患者在外观满意度方面I级占比均明显高于同期对照组(P<0.05),Ⅱ级、Ⅲ级占比均明显低于同期对照组(P<0.05);观察组TNF-α、IL-6均明显低于对照组(P<0.05);观察组继发龋、食物镶嵌两方面I级占比均明显高于对照组(P<0.05),Ⅱ级、Ⅲ级占比均明显低于对照组(P<0.05)。结论:采用超瓷树脂嵌体的修复方式相比采用CAD/CAM复合树脂高嵌体修复对于根管治疗后磨牙大面积缺损患者而言,修复效果更好、龈沟液炎症介质水平更低、患者对修复体外观满意度更高,且并发症发生率更低,适合临床推广使用。Objective To observe the clinical effect of computer-aided design(CAD)/computer-aided manufacturing(CAM)composite resin onlay and super porcelain resin inlay repair on large-area molar defects after root canal therapy.Methods 97 patients with large-area molar defects after root canal therapy from January 2020 to January 2022 were selected as the research subjects,and were divided into control group(n=48)and observation group(n=49)by the randomization method.The observation group was treated with super porcelain resin inlay repair,and the control group was given CAD/CAM composite resin onlay repair.The repair effect,levels of inflammatory mediators in gingival crevicular fluid,patients'satisfaction with prosthesis appearance and occurrence of complications were compared between the two groups after 6 months and 12 months of repair.Results At return visit after 6 months,the proportions of gradeⅠin three aspects of shedding,marginal fit and tooth integrity in observation group were higher than those in control group(P<0.05),while the proportions of gradeⅡand gradeⅢwere slightly lower than those in control group(P<0.05).The proportion of gradeⅠappearance satisfaction was slightly higher in observation group than that in control group(P<0.05),while the proportions of gradeⅡand gradeⅢwere slightly lower compared with those in control group(P<0.05).The levels of tumor necrosis factor(TNF-α)and interleukin(IL-6)in gingival crevicular fluid in observation group were slightly lower compared to control group(P<0.05).The proportions of grade I in secondary caries and food inlays in observation group were slightly higher than those in control group(P<0.05),and the proportions of gradeⅡand gradeⅢwere slightly lower than those in control group(P<0.05).At return visit after 12 months,the proportions of gradeⅠin shedding,marginal fit and tooth integrity in observation group were significantly higher(P<0.05)while the proportions of gradeⅡand gradeⅢwere significantly lower compared to control group(P<0.05).In
