摘要： 乳牙列期或混合牙列期乳牙牙髓治疗后常采用不锈钢预成冠进行修复,但其存在美观性差、过敏、与牙体组织贴合度差的问题,我们结合数字化技术与新型材料聚醚醚酮较好地解决了以上的问题。这份病例报告描述了一种全数字化的工作流程,通过使用口腔内扫描、牙科计算机辅助设计软件和聚醚醚酮切削机器来生产个性化乳牙冠,为患儿提供一种全新的牙体缺损修复方式。

Abstract: Preformed metal crowns are commonly used for restoration following endodontic treatment in deciduous or mixed dentition. However, these crowns suffer from poor aesthetics, hypersensitivity, and inadequate fit to dental tissues. These issues have been addressed by integrating digital technology with polyetheretherketone (PEEK), a novel material. This case report details a fully digital workflow to produce personalized PEEK prefabricated crowns for deciduous teeth using intraoral scanning, dental CAD software, and a PEEK cutting machine. This approach offers a new method for restoring dental defects in pediatric patients.
