| 摘 要： | 目的:评价经标记模板定位后颌骨种植区多层螺旋CT(MSCT)测量的准确性。方法:选择20名志愿者佩戴标记模板,经MSCT扫描后,应用牙颌专用测量软件测量上、下颌前牙唇舌侧龈缘中点间的距离,采用SPSS17.0软件包与游标卡尺手工测量的唇舌距进行配对t检验。结果:各牙位唇、舌侧龈缘中点间距离CT测量值与游标卡尺测量值的差值范围为-0.04~0.21mm,无统计学差异(P>0.05)。结论:经标记模板定位后,颌骨种植区高分辨率CT测量距离与实测距离具有良好的一致性,该方法为活体颌骨种植区精确测量提供了一种可靠的途径。

| Abstract: | PURPOSE:To evaluate the measurement accuracy by multi-slice spiral CT(MSCT) and dental software as a tool for preoperative design before tooth implantations.METHODS: Twenty volunteers with marker template underwent MSCT.The diameter of the front teeth crowns in the bucco-lingual direction were measured by MSCT using a standard dental software package.Postoperatively,the same distances were clinically measured using a sliding caliper.The consistency between the two measurements was analyzed by paired t test ... |
