摘　　要：目的:探究数字化椅旁计算机辅助设计/计算机辅助制造(CAD/CAM)高嵌体对老年磨牙大面积缺损患者的修复效果。方法:选取2016年7月~2020年6月本院收治的75例(75颗缺损牙)老年磨牙大面积缺损患者,行根管治疗后采用椅旁CAD/CAM进行高嵌体修复。评价修复后12、24个月的修复效果,并于修复后24个月调查患者满意度,检测修复前和修复后12、24个月的龈沟液内肿瘤坏死因子-α(TNF-α)和基质金属蛋白酶8(MMP-8)水平。结果:修复后12、24个月的修复合格率分别为97.33%、93.33%,修复后24个月患者在修复体颜色、外形及舒适度三方面的满意率分别为98.67%、97.33%、100%。修复后12、24个月的患牙龈沟液内TNF-α及MMP-8水平较修复前下降(P<0.05)。结论:CAD/CAM技术制作的高嵌体对于老年磨牙大面积缺损的修复效果良好,患者满意度高,可作为老年磨牙大面积缺损的有效治疗方案。Objective:To explore the effect of chairside computer-aided design/computer-aided manufacturing(CAD/CAM)onlay prostheses in the treatment of elderly patients with large molar teeth defects.Methods:A total of 75 elderly patients with large molar teeth defects in our hospital from July 2016 to June 2020 were selected,chairside CAD/CAM onlay prostheses were performed after endodontic treatment.The modified United States public health service standards(USPHS)were used to evaluate the restoration effect at the 12th month and 24th month after restoration.Patients'satisfaction was investigated at the 24th month after operation.Detected the levels of tumor necrosis factor-α(TNF-α)and matrix metalloproteinase 8(MMP-8)in gingival crevicular fluid at the 12th month and 24th month after restoration.Results:The qualified rate was 97.33%and 93.33%at the 12th and 24th month after restoration,respectively.At the 24th month after restoration,the satisfaction rate of patients to the color,shape and comfort of the prostheses was 98.67%,97.33%and 100%,respectively.The levels of TNF-αand MMP-8 at the 12th and 24th month after restoration were lower than those before restoration(P<0.05).Conclusion:The chairside CAD/CAM onlay prostheses have a good effect and high patient satisfaction rate on the restoration which can be used as an effective treatment for elderly patients with large molar teeth defects.
