两种种植导板对牙种植体ted guiding plate in group A and the patients were were
carried out implant surgery under the pioneer drill navigation implanted guiding plate. The buccal cone-beam CT(CBCT) was
compared between preoperative implant placement design and the actual position of postoperative implant, the horizontal and
vertical deviation of implant neck, horizontal and vertical deviation of implant root, center axis angle deviation
of implant was calculated in two groups. Results The horizontal and vertical deviation of implant neck,
horizontal and vertical deviation of implant root, center axis angle deviation of implant was (±) mm,
(±) mm, (±) mm, (±) mm, (±)° in group A, respectively and the horizontal
and vertical deviation of implant neck, horizontal and vertical deviation of implant root, center axis angle deviation of implant
was (±) mm,(±) mm,(±) mm, (±) mm,(±)° in group B, respectively.
There was statistical signifi cance between two groups(P＜). Conclusion The effect of improved whole-course navigation
implanted guiding plate was significantly lower than the pioneer drill navigation implanted guiding plate on implantation
