【摘要】：目的:利用CBCT、3D打印技术等设计制作新型口腔种植导板和种植手机引导装置,应用于临床并对其进行精度评价。方法:利用Mimics、Simplant等软件设计制造种植外科导板,分为套筒引导(A组)和种植手机引导(B组)行种植手术。分析虚拟与实际植体的偏差,比较2组的精确度是否有统计学差异。结果:15例患者的92枚植体,A组44枚和B组48枚,测量虚拟与实际植体在颈部、顶部、深度、角度偏离值:(0.82±0.47)mm,(0.97±0.52)mm,(0.81±0.42)mm,(7.89±4.24)°。两独立样本t检验,双侧α=0.05,得到A组和B组差异无统计学意义,不认为两者的偏离值的总体均数不相等。结论:套筒引导和种植手机引导精确度基本无差别,两者的联合应用具有较高的精确性等优点。
[Abstract]:Aim: to design and manufacture a new type of dental implant guide plate and implant mobile phone guide device by using CBCTT 3D printing technology, and to evaluate the accuracy of the device. Methods: the implants were designed and manufactured by MimicsSimplant and were divided into two groups: group A (guided by sleeve) and group B (guided by mobile phone). The deviation between virtual and actual implants was analyzed and the accuracy of the two groups was compared. Results 92 implants in group A (n = 15) and group B (n = 48) were measured at neck, top, depth, angle deviation of 0.97 卤0.52 卤0.42 卤0.42 卤7.89 卤4.24 掳. T test of two independent samples showed that there was no significant difference between group A and group B, and the total mean of deviation between group A and group B was not equal. Conclusion: there is no difference in guiding accuracy between sleeve guide and implant mobile phone.
