摘　　要：目的评价一种新型经口外装置控制的静态引导种植系统的临床精度与临床使用情况。材料和方法临床招募单牙缺失骨量充足拟行种植修复治疗的患者45名,根据手术操作方式分为自由手组(A组)、静态导板组(B组)、口外静态装置组(C组),通过评估术后患者满意度及医生操作体验评分,探讨不同术式的临床医患满意度,通过对比种植体实际植入位置与虚拟种植位置之间的差异,评价这种新型定位装置引导种植外科的临床精度。结果三组术式的入口偏差无统计学差异[(1.18±0.48)mm,(1.07±0.47)mm,(0.83±0.37)mm,P>0.05];口外静态装置组在尖端及角度方面的偏差明显小于另外两组,差异具有统计学意义[尖端偏差:(1.60±0.76)mm,(1.42±0.40)mm,(1.03±0.54)mm,P<0.05;角度偏差:5.71°±3.54°,4.63°±2.52°,2.75°±1.90°,P<0.05]。三组患者的满意度评分为90~100,差异不具有统计学意义(P>0.05)。医生操作体验感评分中,对于手术视野满意度评分浮动较大,为60~100;其余各项评分在70~90,90~100之间。结论单牙缺失骨量充足时,经口外装置控制的新型静态引导种植系统可以实现良好的精度,具有一定的患者满意度和医生体验感。Objective To evaluate the clinical application and accuracy of a new static guided implant surgery system controlled by an extraoral device.Methods Fortyfive patients with a single tooth missing were recruited,and the available bone of all included cases was sufficient.The patients were divided into three groups according to different surgical approaches:group 1,implantation with freehand;group 2,implantation guided by static surgery guide;and group 3,implantation guided via the new implant surgery system controlled by the extraoral device.By comparing the difference between the actual and virtual implant positions among the three groups,the clinical accuracy of the new implant surgery system was evaluated.Patient-reported outcome measurements(PROMS)and the operator related satisfaction were also evaluated.Results No statistical differences were found among groups with regard to the entrance deviation[(1.18±0.48)mm,(1.07±0.47)mm,(0.83±0.37)mm,P>0.05].The accuracy of the new implant surgery system group at the apical part and for the angle aspect was higher than the other two groups[apical deviation:(1.60±6.76)mm,(1.42±4.40)mm,(1.03±0.54)mm,P<0.05;angle deviation:5.71°±3.54°,4.63°±2.52°,2.75°±1.90°P<0.05].For PROMS,there was no statistical difference among groups(P>0.05),and for the operator related satisfaction,the score of the operation visual field availability fluctuates greatly,ranging from 60 to 100.The score of other items was 70 to 90 and 90 to100.Conclusion For single tooth implantation with sufficient available bone,this new static guided system controlled by the extraoral device can achieve predictable clinical accuracy and acceptable patient and operator satisfaction.
