研究目的:

本研究拟通过拔牙导板的设计、3D打印和应用,在术前以3D打印精准地反映患牙及相邻组织,再根据模型设计出手术导板。术中先通过导板精准去骨,使要拔除的患牙显露,再依靠导板的指引去除牙冠,解除阻力,同时保护临近组织不受损伤,最终拔除患牙。  

Objectives of Study:

This study aims to design, 3D printing and make customized fixation plates, with help of the precise reflection of the impacted tooth and its adjacent tissues by 3D printing before operation. During the operation, the bone is precisely removed through the guidance of the fixation plate to expose the impated tooth. Then, the crown is removed under the guidance of the plate to eliminate resistance and protect the adjacent tissues before the impacted tooth is extracted.

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:

原始数据使用院内电子病历系统记录,该系统为内部系统,仅供院内访问。病例报告表及项目专用电子表格进行数据采集时,由专人进行,以患者编号代替患者姓名,不记录敏感信息,治疗信息的采集符合最小必要性原则。充分保障患者的隐/私权利及数据的真实性、科学性、准确性。

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

The raw data were recorded using the hospital electronic medical record system, which is an internal system and accessible only to the hospital. Data collection from the case report form and the project-specific spreadsheet should be carried out by specially-assigned person, patient number should be used instead of patient name, sensitive information should not be recorded, and collection of treatment information should comply with the principle of least necessity. The privacy rights of patients and the authenticity, scientificity and accuracy of data are fully guaranteed.
