摘要
目的探讨计算机辅助设计/计算机辅助制造(CAD/CAM)高嵌体与传统印模全瓷冠修复在牙体大面积缺损中的应用效果。方法选取2019年2月至2021年2月厦门医学院附属口腔医院收治的86例牙体大面积缺损患者作为研究对象,采用随机数字表法将患者分为对照组(43例)和观察组(43例)。对照组患者予以传统印模全瓷冠修复,观察组患者予以CAD/CAM高嵌体修复,两组均随访6个月。比较两组患者的修复效果、牙周状况[菌斑指数(PLI)、牙周袋深度(PD)、牙龈指数(GI)]、咀嚼功能及并发症发生情况。结果观察组患者的修复体颜色匹配度、表面光滑度、边缘密合度及修复体完整性分别为97.67%、95.35%、100.00%、95.35%,高于对照组的81.40%、79.07%、86.05%、81.40%,差异有统计学意义(P<0.05);两组患者修复前的牙周状况比较,差异无统计学意义(P>0.05);两组患者修复后的PLI、PD、GI低于修复前,差异有统计学意义(P<0.05);观察组患者修复后的PLI[(0.61±0.15)分]、PD[(0.77±0.14)mm]、GI[(0.53±0.13)分],均低于对照组的(0.73±0.18)分、(1.05±0.21)mm、(0.67±0.16)分,差异有统计学意义(P<0.05);两组患者修复前的咬合力、咀嚼效率比较,差异无统计学意义(P>0.05);两组患者修复后的咬合力、咀嚼效率高于修复前,差异有统计学意义(P<0.05);观察组患者修复后的咬合力[(61.58±6.12)kg]、咀嚼效率[(89.58±7.13)%],均高于对照组的(56.54±5.83)kg、(82.14±6.87)%,差异有统计学意义(P<0.05);观察组患者的并发症总发生率为4.65%,低于对照组的18.60%,差异有统计学意义(P<0.05)。结论CAD/CAM高嵌体在修复牙体大面积缺损中的应用效果更佳,能提高修复效果,改善牙周状况,增强咀嚼功能,减少修复后并发症的发生。
Objective To investigate the application effect of computer aided design/computer aided manufacturing(CAD/CAM)high inlay and traditional impression all ceramic crown in the repair of large-area tooth defects.Methods A total of 86 patients with large-area tooth defects treated in the Stomatology Hospital Affiliated to Xiamen Medical College from February 2019 to February 2021 were selected as the research objects.Patients were divided into control group(43 cases)and observation group(43 cases)by random number table method.The control group was repaired with traditional impression all ceramic crown,and the observation group was repaired with CAD/CAM high inlay.They were followed up for 6 months.The restoration effect,periodontal status(plaque index[PLI],periodontal pocket depth[PD],gingival index[GI]),masticatory function and complications were compared between the two groups.Results The color matching degree,surface smoothness,edge tightness and restoration integrity in the observation group were 97.67%,95.35%,100.00%and 95.35%,respectively,which were higher than 81.40%,79.07%,86.05%and 81.40%in the control group,with statistically significant differences(P<0.05).There was no significant difference in periodontal status between the two groups before repair(P>0.05).The PLI,PD and GI of the two groups after repair were lower than those before repair,with statistically significant differences(P<0.05).The PLI([0.61±0.15]points),PD([0.77±0.14]mm)and GI([0.53±0.13]points]in the observation group were lower than those in the control group of(0.73±0.18)points,(1.05±0.21)mm and(0.67±0.16)points,with statistically significant differences(P<0.05).There were no significant differences in bite force and chewing efficiency between the two groups before repair(P>0.05).The bite force and masticatory efficiency of the two groups after repair were higher than those before repair,with statistically significant differences(P<0.05).The bite force([61.58±6.12]kg)and masticatory efficiency([89.58±7.13]%)in the observation group
