研究目的: |
本项目针对“树脂充填恢复磨牙大面积缺损生理形态”这一关键临床问题展开研究,拟采用数字化技术进行虚拟充填,恢复患牙形态和咬合关系并生成目标修复体,结合逆向工程原理设计充填印章,基于复面洞序列充填的理念生成充填导板,采用三维打印制作基于印章法的充填修复序列导板;重点研究数字化技术制作序列导板流程中不同平台、软件之间的整合,制定相应的技术路径和规范,并且评估序列导板所恢复的充填体形态准确度;最后,通过临床随机对照研究评估序列导板用于磨牙大面积颊牙合面缺损充填修复技术敏感性和临床效果。本研究有望填补三维打印序列导板技术在牙体缺损的树脂直接粘接修复领域的空白,为磨牙大面积缺损的修复提供新方法、新思路。 |

Objectives of Study: |
This study aims at the key clinical problem of "resin filling to restore the physiological morphology of large molar defects". It is planned to use digital technology to carry out the virtual filling, restore the morphology and occlusal relationship of the affected teeth generate the target restoration, design and create the filling guide in combination with the principle of reverse engineering, and use 3D printing to produce the sequence guide. This study focuses on the integration of different platforms and software in the process of making sequence guides by digital technology, formulates corresponding technical paths, and evaluates the accuracy and clinical effect of sequence guides via a clinical randomized controlled study. This study is expected to fill the gap of 3D printing sequence guide technology in the field of direct resin restoration of tooth defects and provide new methods and ideas for the restoration of large molar defects. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study uses both paper and electronic data recording methods. First, the data is recorded in paper form as a raw record. After that, the data was completely, and correctly loaded into an electronic sheet based on the original records. After the original data is entered and verified as required, it shall be archived and stored in the order of numbering, and the retrieval directory shall be filled in for reference. After the original data is converted into electronic data documents and forms, multiple backups are generated and saved on different recording media, which are properly stored to prevent damage and loss. |
