研究目的:

探索CPC-I型和CPC-II型对单牙缺失或连续两牙缺失牙槽嵴保存的应用及其疗效对比。通过前瞻性临床随机对照研究,比较两种不同类型的CPC骨粉对牙槽嵴宽度保存的作用。从而进一步指导CPC-I型和CPC-II型对单牙缺失或连续两牙缺失牙槽嵴保存的选择和应用。  

Objectives of Study:

Explore the application of CPC-I and CPC-II in the preservation of single tooth loss or continuous two tooth loss and the comparison of their effects. Through a prospective clinical randomized controlled study, the effects of two different types of CPC bone meal on the preservation of alveolar ridge width were compared. This will further guide the selection and application of CPC-I and CPC-II for the preservation of single tooth loss or two consecutive tooth loss.

随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机法进行随机分组。将受试对象分为单牙和连续双牙缺失(均为单根牙)两个亚组,在两个亚组中,通过区组随机法将受试对象按1:1比例分为干预组与对照组,由第三方统计师利用SAS软件生成随机数字,并绘制分配序列表,将其依次放入按顺利编码、密封、不透光的信封中,后移交给研究者。当研究者确定受试者的合格性后,按顺序拆开信封并记录受试者的组别及基本信息。

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

The stratified block random method was used for random grouping. The subjects were divided into two subgroups of single tooth and continuous double tooth loss (both single teeth). In the two subgroups, the subjects were divided into the intervention group at a ratio of 1:1 by the block random method

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:

本研究同时采用病例报告表及电子采集和管理系统(Castor数据库) (1)研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入病例报告表。 (2)监查员监查试验的进行是否遵循试验方案。确认所有病例报告表填写正确完整,并与原始资料一致。如有错误和遗漏,及时要求研究者改正。修改时需保持原有记录清晰可见,改正处需经研究者签名并注明日期。 (3)经过监查员检查后的病例报告表,由监查员核查签字后,及时送交临床试验数据管理员。对于完成的病例报告表在研究者、监查员、数据管理员之间的传送应有专门的记录,收到时应有相应的签名,记录需妥善保存。 (4)数据管理员在数据录入前再次核查,发现问题及时通知监查员,要求研究者作出回答。他们之间的各种疑问及解答的交换应当采用疑问表形式,疑问表应保存备查。 (5)数据管理员在进行数据录入前,要了解观察表格各项目的内容及编码情况,将编码工作过程记录于编码本保存。数据库命名应规范、易读、易查找。并保证其正确、安全和保密。 (6)数据录入员录入数据采用二次录入。录入过程发现问题或意外情况,应做好登记并及时报告,以便迅速处理问题,数据录入结束后应抽查部分观察表格,了解录入质量,分析并处理存在的问题。 (7)数据管理员应与主要研究者一起,按病例报告表中各指标数值的范围和相互关系拟定数据范围检查和逻辑检查内容。并编写相应的计算机程序,在输入前控制错误数据输入,找出错误原因加以改正,所有错误内容及修改结果应有记录并妥善保存。 (8)原始病例报告表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。电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。所有原始档案应按我国《临床试验质量管理规范》的规定期限保存。

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

This study uses case report forms and an electronic collection and management system (Castor database) (1) According to the subjects’ original observation records, the researcher will load the data into the case report form in a timely, complete, correct and clear manner. (2) The inspector monitors whether the test is carried out in accordance with the test plan. Confirm that all case report forms are filled in correctly and completely, and are consistent with the original data. If there are errors or omissions, the researchers are required to correct them in time. The original record must be kept clearly visible when making changes, and the corrections must be signed and dated by the researcher. (3) The case report form after inspection by the inspector shall be checked and signed by the inspector and sent to the clinical trial data manager in time. There should be a special record for the transmission of the completed case report form between the investigator, the inspector, and the data manager, and the corresponding signature should be provided when received, and the record should be properly kept. (4) The data administrator checks again before data entry, and promptly informs the inspector when any problems are found, and asks the researcher to answer. The exchange of various questions and answers between them should be in the form of question sheets, which should be kept for future reference. (5) Before data entry, the data administrator should understand the content and coding situation of each item in the observation form, and record the coding process in the coding book. The database naming should be standardized, easy to read and easy to find. And to ensure its accuracy, safety and confidentiality. (6) The data entered by the data entry staff uses secondary entry. If problems or unexpected situations are discovered during the entry process, they should be registered and reported in a timely manner to quickly deal with the problems. After the data entry is completed, some observation forms should be checked randomly to understand the entry quality, analyze and deal with the existing problems. (7) The data manager should work with the principal investigator to formulate data range inspection and logical inspection content according to the range and correlation of the index values ??in the case report form. And write the corresponding computer program, control the input of the wrong data before inputting, find the cause of the error and correct it, and all the error content and the modification result should be recorded and properly stored. (8) After completing data entry and verification as required, the original case report form is archived and stored in the order of number, and filled with a search catalog for future reference. Electronic data files include databases, inspection procedures, analysis procedures, analysis results, codebooks and explanatory documents, etc., which should be stored in categories, and multiple backups should be stored on different disks or recording media, properly stored to prevent damage. All original files should be kept in accordance with the stipulated period of my country's "Clinical Trial Quality Management Practice".
