Cohort study 

研究目的:

在一年的随访时间内,研究NobelParallel? CC短种植体在下颌后牙区的临床应用效果,作为短种植体组,并同时研究常规种植体联合骨增量手术在下颌后牙区的临床效果,作为对照组,最后比较短种植体和常规种植体的临床效果是否有差异。  

Objectives of Study:

Within one year of follow-up, clinical outcomes of NobelParallel Conical Connection Short implants, as short implant group, in atrophic posterior mandibles and conventional implants with bone augmentation, as control group, in atrophic posterior mandibles would be studied to compare short implants and conventional implants.

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:

通过填写CRF表,进行数据采集。然后对病例报告表中数据进行核查,发现疑问向研究者询问,根据研究者的回答进行数据修改、确认;将CRF的数据输入计算机,建立数据库并进行二次检错,数据锁定和储存后,由统计分析人员进行分析。

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

Researchers collect the data by CRF,then check the data in CRF, ask the researchers if there are any questions, and modify and confirm the data according to the answers given by the researchers; after the data is entered into the computer, establish a database and double error detection of data. After the data is locked and stored, it is analyzed by statistical analysts.
