摘要/Abstract

摘要： 目的: 对青少年颧牙槽嵴区皮质骨厚度进行测量分析,探讨其与颈椎骨龄的相关性。方法: 采集80例青少年患者的锥形束CT数据,其中颈椎骨龄为Cvs3、Cvs4、Cvs5及Cvs6的青少年各20例。以上颌平面为基准平面,重建CBCT图像,分别以与基准平面平行及成60°角的测量方向测量左侧上颌颧牙槽嵴区不同层面皮质骨厚度。采用SPSS 21.0软件包对测量数据进行统计学分析。结果: 当测量方向与基准平面平行及成60°时Cvs3~Cvs6青少年颧牙槽嵴区皮质骨厚度分别为（0.90±0.09）~（1.72±0.21） mm及（1.35±0.44）~（3.98±1.48） mm,Cvs4、Cvs5两组相比皮质骨厚度差异显著（P<0.05）。Spearman相关分析结果表明,颧牙槽嵴区皮质骨厚度与颈椎骨龄呈显著正相关（P<0.01）。结论: 青少年颧牙槽嵴区皮质骨厚度随颈椎骨龄的增长而增大,在Cvs4~Cvs5期间皮质骨厚度可能出现显著增大。就皮质骨厚度而言,Cvs3~Cvs6青少年颧牙槽嵴区各层面均适合植入微种植钉,而Cvs3、Cvs4青少年应尽量选取靠前的层面植入。

Abstract: PURPOSE: To measure the cortical bone thickness of zygomatic alveolar ridge in adolescents and explore the correlation between cortical bone thickness and cervical vertebral bone age. METHODS: Cone-beam CT data of 80 adolescents were collected, including 20 adolescents with cervical vertebral bone ages of Cvs3, Cvs4, Cvs5 and Cvs6, respectively. CBCT images were reconstructed with the maxillary occlusal plane as the reference plane. Cortical bone thickness of different slices in the left maxillary zygomatic alveolar ridge area was measured in the direction parallel to and 60° from the reference plane, and the measured data were statistically analyzed by SPSS 21.0 software package. RESULTS: When the measurement direction was parallel to the reference plane and at 60°, the cortical bone thickness in the zygomatic alveolar ridge area of Cvs3-Cvs6 adolescents was (0.90±0.09) -(1.72±0.21) mm and (1.35±0.44)-(3.98±1.48) mm, respectively. There was significant difference in cortical bone thickness between Cvs4 and Cvs5 group(P<0.05). Spearman correlation analysis showed a strong positive correlation(P<0.01) between cortical bone thickness of zygomatic alveolar ridge and cervical vertebral bone age in adolescents. CONCLUSIONS: The cortical bone thickness of zygomatic alveolar ridge in adolescents increases with the increase of cervical vertebral bone age, and the cortical bone thickness may increase significantly during Cvs4-Cvs5. In terms of cortical bone thickness, all slices of zygomatic alveolar ridge of CVS3-CVS6 adolescents are suitable for implanting miniscrews, and the anterior slices should be selected for implantation as far as possible for Cvs3 and Cvs4 adolescents.
