摘要

这个数字临床报告提出了一种新的CAD-CAM工作流,用于制造定制的单片氧化锆桩核修复体。一位26岁的女性患者需要修复上颌左第一和第二前磨牙,并为上颌左第一磨牙种植螺钉保留冠(ISRC)。在支架空间准备后,在有或没有预制纤维支架的情况下进行口内扫描(IOS)。光纤桩也分别用台式扫描仪扫描。使用数字软件将这些数据集叠加,设计出精确的单片氧化锆桩核,然后使用CAD-CAM技术对其进行铣削。采用自粘树脂胶粘剂对结构进行胶结,并用数字技术设计和制造了二硅酸锂冠。这种数字化方法最大限度地减少了与传统技术相关的错误,提高了适应性和适应性,提高了临床效率。最终修复获得了良好的美学和功能结果,满足了患者的期望,无并发症。本报告强调了数字工作流程在实现桩核修复的精确性和可预测性方面的价值。

A novel CAD-CAM protocol for monolithic zirconia post and core fabrication: A digital clinical report.

This digital clinical report presents a novel CAD-CAM workflow for fabricating a customized monolithic zirconia post-and-core restoration. A 26-year-old female patient required prosthetic rehabilitation of the maxillary left first and second premolars, as well as an implant screw-retained crown (ISRC) for the maxillary left first molar. After post space preparation, intraoral scans (IOS) were obtained both with and without a prefabricated fiber post in place. The fiber post was also scanned separately using a desktop scanner. These datasets were superimposed using digital software to design a precise monolithic zirconia post-and-core, which was then milled using CAD-CAM technology. The structure was cemented with self-adhesive resin cement, and a lithium disilicate crown was digitally designed and fabricated. This digital approach minimized the errors associated with conventional techniques, improved fit and adaptation, and enhanced clinical efficiency. The definitive restoration achieved excellent aesthetic and functional outcomes, fulfilling the patient's expectations without complications. This report highlights the value of digital workflows in achieving precision and predictability in post-and-core restorations.

期刊介绍: The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
