研究目的: |
本项目旨在前期研究的基础上,针对现有的金属预成冠与缺隙保持器不能满足患儿美观安全需求且临床成功率较低等难题,使用3D打印技术将具有良好的美学性能、生物安全性及物理机械性能的PEEK材料用于制作乳磨牙冠修复体及缺隙保持器,本研究为儿童龋病个性化治疗提供新的、更为完善的解决思路。 |

|
Objectives of Study: |
This project aims to address the challenges posed by existing metal preformed crowns and space maintainers, which cannot meet aesthetic and safety needs of pediatric patients and have low clinical success rates. Based on previous research, this project will utilize 3D printing technology to fabricate primary molar crowns and space maintainers using PEEK material, which exhibits excellent aesthetic properties, biological safety, and physical mechanical performance. This study provides new and more comprehensive solutions for personalized treatment of pediatric dental caries. |
