Abstract

PURPOSE

To determine the height and volume of the mandibular coronoid process (CP) by cone-beam computed tomography (CBCT) and to identify the presence of any correlations of these measurements with age, gender, facial type, and skeletal class.

MATERIALS AND METHODS

The sample consisted of 132 patients from a departmental routine patient base. After CBCT, CP height was determined using OnDemand 3D software (CyberMed, Seoul, Republic of Korea), and CP volume was obtained using ITK-SNAP 3.0 software (Cognitica, Philadelphia, PA). Measurements were subjected to analysis of covariance against facial type, skeletal class, gender, and age, with a significance level of 5%.

RESULTS

CP height and volume were similar regardless of age, facial type, and skeletal class. However, the 2 measurements were statistically different regarding gender, with larger values for men than for women.

CONCLUSIONS

These observations suggest that gender is the only factor influencing the height and volume of the CP.

摘要

目的

通过锥形束计算机断层扫描（CBCT）确定下颌冠突（CP）的高度和体积，并确定这些测量值与年龄、性别、面部类型和骨骼类型之间是否存在相关性。

材料与方法

样本包括来自科室常规患者库的132例患者。CBCT扫描后，使用OnDemand 3D软件（韩国首尔CyberMed公司）确定CP高度，并使用ITK-SNAP 3.0软件（美国宾夕法尼亚州费城Cognitica公司）获得CP体积。测量值针对面部类型、骨骼类型、性别和年龄进行协方差分析，显著性水平为5%。
