目的：利用螺旋CT检查数据结合Mimics软件对颏孔的解剖形态进行观察和测量，以减免种植术中损伤该区解剖结构。方法：将螺旋CT数据结合Mimics软件，重建三维图像，对颏管区进行透视观察，观测颏孔的位置，大小以及开口方向进行观察和测量。结果：颏管区重建的可视化三维数字模型，可进行多方位对颏管区的解剖结构进行测量和综合评价；颏孔位于下颌第二前磨牙根尖区占65.83%，位于第一前磨牙与第二前磨牙之间的下占21.67%，位于第二前磨牙与第一磨牙之间的下方占12.50%，同性别左右之间以及男女性之间颏孔位置的分布，差异均无统计学意义。颏孔(横径和纵径)同性别左右比较，其差异无统计学意义；不同性别之间比较，其差异有统计学意义(P＜0.05)，男性大于女性。颏孔的开口方向，第1区占50.83%，第2区占40.83%，第4象占5.83%，第5区占4.17%，第6区占0.83%，第7区占0.83%，第8区占6.67%，两个开口方向的占10.38%。结论：螺旋CT结合Mimics软件可建立颏管区三维可视化模型，并且可以进行对颏孔进行准确的观测。

Objective:To investigate the anatomical characteristics of mental canal area by using Spiral CT combined with Mimics software in order to avoid the injury of the anatomical structure during dental implantation. Methods:The CT digital imaging data were obtained, and transformed to two-grade reconstructed images of Spiral CT, and then analyzed by using Mimics software. Results:65.83%of the mental foramen were located in the mandible second premolar root zone, 21.67%in the mandible between the first and second premolar, and 12.50%in the mandible between the second premolar and the first molar. There were no statistically significant differences regarding the distribution of mental foramen position between left and right sides in the same gender, and/or in different gender. Regarding the diameter and longitudinal diame-ter of the mental foramen, there were no statistically significant differences between left and right in the same gender. How-ever, there was statistically significant difference regarding comparisons in different gender (P<0.05). Spiral CT data were converted into a visual 3D digital models by mimics softwares, and could provide sufficient information, measure and given comprehensive evaluation on the anatomic structure of mandibular mental canal. Conclusion: Spiral CT combined with Mimics software provides precise measurements on mental canal area, and establishes the visual 3D model of the structure before dental implantation. It also facilitates doctor-patient communication, diagnosis, treatment and effective evaluation on dental implant.
