测量指标:

Outcomes:

指标中文名:

颞区和面颊区软组织的三维形态变化

指标类型:

主要指标

Outcome:

Three-dimensional Morphological Changes of Temporal and Buccal Soft Tissues

Type:

Primary indicator

测量时间点:

治疗开始后0、3、6、12个月

测量方法:

将图像导入Geomagic qualified软件,生成高精度的三维头部模型和颜色信息。根据额部、鼻根、颧部等稳定区域,将获得的三维数据与T0时刻的图像重叠,计算不同时间段的面部变化。在软件中选取颞区及面颊区作为三维形态分析的目标区域,进行定量三维偏差分析,计算叠加面部网格在区域内的平均三维距离偏差。

Measure time point of outcome:

At 0, 3, 6, and 12 months after treatment initiation

Measure method:

Images were imported into Geomagic Qualified software to generate high-precision 3D head models with color information. Using stable anatomical regions (frontal region, nasion, zygomatic region, etc.), 3D data were overlapped with the baseline (T0) image to calculate facial changes over different time periods.The temporal and buccal regions were selected as target areas for 3D morphological analysis. Quantitative 3D deviation analysis was performed by calculating the average 3D distance deviatio

指标中文名:

垂直骨面型变化

指标类型:

次要指标

Outcome:

Vertical Skeletal Pattern Changes

Type:

Secondary indicator

测量时间点:

治疗开始前及治疗开始12个月

测量方法:

计算治疗前MP/SN、MP/FH、S-G0/N-Me,正畸治疗12个月时的头影测量值变化:ΔMP/SN、ΔMP/FH、ΔS-G0/N-Me等指标

Measure time point of outcome:

Vertical Skeletal Pattern Changes before Treatment and at 12 Months after Treatment

Measure method:

Cephalometric indices including MP/SN, MP/FH, and S-Go/N-Me were measured on lateral cephalograms taken before treatment and at 12 months. Changes (Δ values) were calculated as follow-up values minus baseline values.

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:

研究者通过对图像的测量分析,将测量数据及时、完整、正确、清晰地载入电子记录表格。录入采用双人双机录入。原始数据在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备查考。

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

Researchers, through the measurement and analysis of images, promptly, completely, accurately and clearly load the measurement data into the electronic record sheet. Input is carried out by two people using two machines. After the original data is entered and verified as required, it is archived and saved in the order of their numbers, and a search directory and other information are filled in for future reference.
