摘要/Abstract

摘要： 目的: 通过CBCT三维重建测量前鼻棘区潜在取骨量,为前鼻棘区作为自体骨取骨位点的临床应用提供参考。方法: 将300例CBCT数据导入Mimics软件进行三维重建,按性别、年龄及鼻腭管分型进行分组,对各组前鼻棘潜在取骨量相关参数进行统计学分析。结果: 男性、女性前鼻棘区潜在取骨体积分别为(377.05±115.69) mm³、(334.33±109.75) mm³,男性大于女性(P<0.05)。青年组、中年组、老年组的潜在取骨体积分别为(331.70±101.51) mm³、(371.26±122.64) mm³、(375.46±118.05) mm³,中年组、老年组大于青年组(P<0.05)。漏斗形组、沙漏形组、圆柱形组、纺锤形组的潜在取骨体积分别为(321.83±119.28) mm³、(391.44±117.21) mm³、(353.03±108.44) mm³、(344.09±103.24) mm³,沙漏形组大于其余3组(P＜0.05)。结论: 前鼻棘区可作为上前牙区骨增量的取骨位点,术前可利用CBCT三维重建对潜在取骨量进行测量评估。

Abstract: Objective: To measure the potential bone quantity harvested from the anterior nasal spine area by CBCT three-dimensional(3D) reconstruction, and to provide reference for the clinical application of the area as a site for autogenous bone harvesting. Methods: The CBCT data of 300 cases were imported into Mimics software. According to gender, age, and nasopalatine canal, the related parameters were statistically analyzed.Results: The potential bone volumes of the area in men and women were (377.05±115.69)mm³and (334.33±109.75)mm³, respectively (P<0.05). The potential bone volumes of the young group, middle-aged group, and elderly group were (331.70±101.51)mm³, (371.26±122.64)mm³,and (375.46±118.05)mm³, respectively. The volumes of middle-aged group and the elderly group were larger than that of young group (P<0.05). The potential bone volumes of the funnel-shaped group, hourglass-shaped group, cylindrical group, and spindle-shaped group were (321.83±119.28)mm³, (391.44±117.21)mm³, (353.03±108.44)mm³,and (344.09±103.24)mm³, respectively. The volume of hourglass-shaped group was larger than those of other three groups (P<0.05). Conclusion: The anterior nasal spine area can be used as autogenous bone harvesting site for bone augmentation in the upper anterior teeth area. Preoperative CBCT 3D reconstruction can be used to measure and evaluate the potential bone quantity.
