研究目的:

1、进行系统性的临床随机对照研究,通过锥体束CT等三维手段对上颌反复扩缩面罩前方牵引治疗的机制机理进行研究分析,并进一步明确其效果。 2、通过研究,进一步明确其适应证,并在上颌扩缩速度、扩弓量和时间等具体技术步骤细节上进行讨论。建立上颌扩缩面罩前方牵引治疗技术的临床治疗规范,为临床大范围应用和推广建立标准。  

Objectives of Study:

1. The objective of this randomized controlled trial was to investigate the effects and mechanisms of facemask protraction combined with alternate rapid maxillary expansions and constrictions vs rapid maxillary expansion alone in the early treatment of maxillary retrusive patients by using CBCT; 2. To investigate the procedure details of facemask protraction combined with alternate rapid maxillary expansions and constrictions, such as the indication, the speed and duration of rapid maxillary expansion, in order to establish a clinical guideline and promote its application.

研究前刘伟涛医师使用随机化区组设计的方法分组,区组长度为6,查随机数字表,选取6种可能的排序方式,并同时将6小组排序。新顺序下的分组即为最终随机分组方案。按患者接诊顺序依次纳入单次扩弓组和反复扩缩组,每组18例。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients were recruited and allocated to either the control group (RME) or the intervention group (Alt-RAMEC) according to their participation sequence. Randomization was accomplished by generating random permuted blocks. Every 6 consecutive positions were placed in a block and numbered by using a random number table.&

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:

利用三维图像处理软件测量相关项目,并将结果手工录入EXCEL表格中,由研究者保存数据。

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

The related items are measured by specific computer software, and the results are manually entered into the EXCEL form. The data are saved by investigators.
