Description

锥形束CT测量牙周垂直型骨缺损体积方法
技术领域
本发明涉及一种口腔医学，具体涉及一种锥形束CT测量牙周垂直型骨缺损体积方法。
背景技术
目前常用的检查牙周垂直型骨缺损的手段为临床牙周探诊检查、放射学评价这两种方法。
在放射学评价中，常规使用的是X线根尖片检查，有些研究配合使用数字减影，但无法从三维方向上对牙周垂直型骨缺损进行检查。垂直型骨缺损实际上是三维立体的缺损，应当进行立体化的评价，因此锥形束CT(Conebeamcomputedtomography,CBCT)是良好的评价手段，因其能提供三维数据。但目前在CBCT应用中，多是在三维方向上对骨缺损进行简单的线性测量，尚无采用体积进行立体化评价的方法。
发明内容
本发明的目的是提供一种锥形束CT测量牙周垂直型骨缺损体积的方法，能获得牙周垂直型骨缺损立体可视化外形，并为采用组织工程学方法治疗骨缺损奠定基础，提高诊疗效率和质量。
为了达到上述目的，本发明有如下技术方案：
本发明的一种锥形束CT测量牙周垂直型骨缺损体积的方法，有以下步骤：
(1)使用CBCT的高清和小视野模式对牙周垂直型骨缺损进行拍摄，获取目标牙齿及周围牙周组织图像；
(2)调整图像的方向,使横断面垂直牙长轴,选取0.125mm层厚，对整个拍摄部位进行三维重建，并存储为dicom格式的文件；
(3)将CBCT获得的三维图像导入mimics软件后，在计算机上通过mimics软件将牙周垂直型骨缺损病损边界进行确定，进行虚拟建模，获得牙周垂直型骨缺损病损的外形；
(4)使用mimics软件获取虚拟建模后的牙周垂直型骨缺损体积。
本发明的优点在于：可有效提高牙周垂直型骨缺损诊断的准确性，获得牙周垂直型骨缺损立体可视化外形，提高诊疗效率和质量，具有广阔的临床需求和市场前景，能在基层医院中进行积极地推广。
具体实施方式
以下实施例用于说明本发明，但不用来限制本发明的范围。
