摘　　要：目的:探讨人工智能(AI)设计的氧化锆全冠与传统计算机辅助设计和制造(CAD/CAM)设计的氧化锆全冠修复磨牙牙体缺损的临床效果。方法:选取116例磨牙根管治疗术后患者,采用随机数字表法将其随机分为实验组(AI设计的氧化锆全冠修复)和对照组(传统CAD/CAM设计的氧化锆全冠修复),每组各58例。对所有患者修复体试戴、粘固后即刻和戴牙1年后修复体边缘折裂与固位、边缘适应性、邻面解剖形态、牙周、周围黏膜、咬合适应性等进行评分。分别记录两组修复体设计所需要的时长、患者椅旁总计就诊时长。调查患者满意度,比较两组的修复治疗效果。结果:根据FDI评价标准对修复体进行临床修复效果评价,实验组牙冠外展隙形态更接近于天然牙,而对照组牙冠外展隙部位缺乏自然的颈部缩窄,实验组牙冠邻面解剖形态评分明显低于对照组(P<0.05);经过调磨后,在修复体粘固即刻及1年后复查时两组间该项指标差异无统计学意义(P>0.05),其余指标(边缘折裂与固位、边缘适应性、牙周、周围黏膜、咬合适应性)在修复体试戴、粘固后即刻和修复一年后三个时间点实验组和对照组间差异无统计学意义(P>0.05)。实验组修复体设计总时长及患者椅旁就诊总时长均低于对照组(P<0.001)。修复1年后实验组平均满意度为96.55%,对照组平均满意度为94.83%,差异无统计学意义(P>0.05)。结论:氧化锆全冠修复磨牙缺损时,AI设计的牙冠与传统CAD/CAM设计相比无明显缺陷,可节约时间与成本,适合临床推广使用。Objective:To investigate the clinical effect of artificial intelligence(AI)designed zirconia full crown and traditional CAD/CAM designed zirconia full crown in repairing molar defects.Methods:A total of 116 cases of molars after root canal treatment in our hospital were selected as the research objects.By using random number table method,they were randomly divided into the study group(zirconia full crown restoration designed by AI)and the control group(zirconia full crown restoration designed by traditional CAD/CAM)with 58 cases each.The edge fracture and retention,edge adaptability,adjacent anatomical morphology,periodontal,pe⁃ripheral mucosa and occlusal adaptability were scored for all patients after prosthesis trial,immediately retention and 1 year restoration.The time required for the restoration designs and total patientschair⁃side visit in both groups were recorded and averaged.The satisfac⁃tion of patients was investigated to compare the repair treatment effect of the two groups.Results:According to the FDI evaluation crite⁃ria,the clinical repair effect of the restorations was evaluated.The shape of crown abduction space designed by AI in the control group was more similar to that of natural teeth,while the traditional CAD/CAM designed crown abduction space in the control group lacked natural neck narrowing.The anatomical morphology score of the experimental group was significantly lower than that of the control group,and the difference was statistically significant(P<0.05),indicating that the AI anatomical morphology design was superior to the traditional CAD/CAM design.After adjustment,there were no statistical differences of two groups in the immediate retention of the restorations and the review one year later(P>0.05).There were no significant differences between both experimental and control groups in other indexes(marginal fracture and retention,marginal adaptability,periodontal,peripheral mucosa and occlusal adaptability)after prosthesis trial,immediately retention and 1 year restoration(P
