数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

患者的CBCT导入Dolphin软件进行三维影像重建,根据L1 - MP 角(下中切牙-下颌平面角)将研究对象分为舌倾组、直立组、唇倾组。分别测量牙槽骨附着高度、各水平高度的唇舌侧骨皮质和骨松质的厚度和面积。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The CBCT images of patients with skeletal class III malocclusion were imported into Dolphin software for 3D image reconstruction. The patients were divided into lingual-inclination, upright, and labial-inclination groups. The height of the alveolar bone and the thickness and area of the cortical, cancellous, and total alveolar bone were measured separately on each side of the mandibular central incisors.
