This narrative review aims to provide an overview of recent studies and case reports on three-dimensional (3D) printing, and to verify the applicability of 3D printers in the field of dental prostheses. This review was performed by conducting a search of PubMed. The clinical application of fabricating a prosthesis made with cobalt-chromium is considered possible depending on the material and hardware of the 3D printer. However, it is currently difficult to assess the clinical use of 3D-printed zirconia crowns. Further research is required, such as verification of materials used, margin morphology, and hardware. Clinically acceptable results have been reported for patterns using 3D printers. Interim restorations made using a 3D printer have been reported with good results that are considered clinically usable. Dentures made with 3D printers need further verification in terms of strength and deformation. Custom trays made with 3D printers are clinically useful, however, issues remain with design time and effort. Although several studies have reported the usefulness of 3D printers, further verification is required since 3D printers are still considered new technology.
本综述旨在提供关于三维（3D）打印的最新研究和病例报告的概述，并验证 3D 打印机在牙科修复体领域的适用性。本综述通过在 PubMed 上进行检索来完成。根据 3D 打印机的材料和硬件，制造钴铬合金修复体是可行的。然而，目前还难以评估 3D 打印氧化锆冠的临床应用。需要进一步研究，例如对所用材料、边缘形态和硬件进行验证。使用 3D 打印机制造的模型已报告了临床可接受的结果。使用 3D 打印机制作的临时修复体已报告取得了良好的临床可用效果。使用 3D 打印机制造的义齿在强度和变形方面还需要进一步验证。使用 3D 打印机制作的定制托盘在临床上是有用的，但在设计时间和精力方面仍存在问题。虽然有几项研究报告了 3D 打印机的有用性，但由于 3D 打印机仍被视为新技术，因此仍需要进一步验证。
