Abstract

OBJECTIVES

The aim of the present study was to retrospectively make a volumetric evaluation of symphysis sites of patients by the use of cone beam computed tomography (CBCT).

METHODS

This retrospective study evaluated dentate symphysis region of the mandibles in CBCT scans taken for different reasons in 90 patients (45 women and 45 men). Three-dimensional (3D) data were obtained using a CBCT device Kodak 9000 3D CMOS sensor with optical fiber. CBCT images were then transferred as digital imaging and communications in medicine files and imported into a volumetric-rendering software 3D DOCTOR (Able Software Corp., Lexington, MA) capable of measurements of vector based-segmentation technology for volumetric measurements.

RESULTS

The total average bone volume is 2616.45 mm. Significant differences in average bone volume were found between group I and group IV (P < 0.001). Higher bone volume was obtained in the male groups (2903.01 mm) than in the female groups (2329.88 mm).

CONCLUSIONS

CBCT is a good candidate for 3D assessment of high-contrast structures in the oral region. We suggest that the use of 3D computed tomography in combination with a software program is a dependable means of measuring the volume of the symphysis bone graft.

摘要

目的

本研究的目的是通过使用锥形束计算机断层扫描（CBCT）对患者的耻骨联合部位进行回顾性容积评估。

方法

这项回顾性研究评估了90例患者（45名女性和45名男性）因不同原因进行的CBCT扫描中下颌骨的齿状耻骨联合区域。使用带有光纤的柯达9000 3D CMOS传感器CBCT设备获取三维（3D）数据。然后将CBCT图像作为医学文件中的数字成像和通信进行传输，并导入到能够测量基于矢量分割技术的容积测量的容积渲染软件3D DOCTOR（Able Software Corp.，列克星敦，马萨诸塞州）中。
