摘要:
[摘要]目的:应用锥形束CT比较不同垂直骨面型的成人骨性Ⅱ类患者上下颌切牙牙根周围牙槽骨面积的大小。方法:选择骨
性Ⅱ类患者45例,根据FMA角分为低角型15例、均角型15例、高角型15例。应用Dolphin Imaging11.5三维软件分别测量上下
颌切牙牙根周围不同水平牙槽骨的横断面面积,采用方差分析比较实验数据。结果:低角组患者上颌切牙在根颈1/3处骨面
积最小(P <0.05),在根尖1/3处骨面积大于高角组(P <0.05);低角组患者下颌切牙在根中1/3水平处骨面积大于高角组患者
(P <0.05),在根尖1/3水平处骨面积最大(P <0.05)。结论:低角组患者上下颌切牙根尖周围骨质较多,高角组患者较少。

Abstract:
Abstract: Objective To compare alveolar area around upper and lower incisors among three vertical facial types of skeletal
Class Ⅱ patients with cone beam CT. Methods 45 skeletal Class Ⅱ patients were divided into 15 low angle cases, 15 average
angle cases, and 15 high angle cases by the FMA. The CBCT images were reconstructed by three-dimension Dolphin Imaging
11.5 software. Alveolar area on three levels around incisor roots was measured on cross sections. The measurements were
analyzed using ANOVA. Results In upper incisors, the area around root at apical level of low angle patients was greater than
high angle patients, while low angle patients had the least value at the cervical level. In lower incisors, the area around root at
middle level of low angle patients was greater than high angle patients, and the area around root at apical level are greater than
that in other two groups. Conclusion The amount of alveolar rounding upper and lower incisors in low angle patient was more
than that of the other types. The high angle patients displayed the least bone area.
