Abstract

Objective: Collect and synthesize data on 3D-printed resins used for single-tooth dental crowns.

Methods: A comprehensive search was conducted across MEDLINE/PubMed, Web of Science, and Scopus databases, covering publications from January 2013 to 18th August 2024. Relevant gray literature was also considered. From a total of 2803 records initially identified, 103 studies met the inclusion criteria and were included in the review.

Results: Data were extracted for 47 different 3D-printed resin materials, including information on product names, manufacturers, and chemical compositions. Mechanical properties: flexural strength (124 MPa), load to failure (1397 N), flexural modulus ( 2818 MPa), and Vickers microhardness (20.94 kgf/ mm2). Degree of conversion (27-95.2%); Wear loss (vertical loss: 62-257 μm; volumetric loss: 0.08-20 mm3); Surface roughness (Ra: 2.16 μm); Internal fit (137.26 μm), marginal fit (86.49 μm); Bond strength (16.97- 24.75 MPa). Cellular response and bacterial adhesion showed variability in biocompatibility, influenced by post-processing protocols.

Conclusions: 3D-printed resins dental crowns demonstrate promising in vitro mechanical performance, including fracture resistance values that withstand typical masticatory forces. Studies report generally favorable bond strength, and acceptable internal and marginal adaptation. However, these materials tend to exhibit lower flexural strength, elastic modulus, and hardness when compared to milled resin counterparts.

3d打印树脂用于单牙牙冠的比较评价-临时和永久：范围审查。

目的：收集和合成单牙冠3d打印树脂的相关数据。方法：综合检索MEDLINE/PubMed、Web of Science和Scopus数据库，涵盖2013年1月至2024年8月18日的出版物。并参考了相关灰色文献。从最初确定的2803份记录中，有103项研究符合纳入标准并被纳入本综述。结果：提取了47种不同的3d打印树脂材料的数据，包括产品名称、制造商和化学成分的信息。机械性能：抗弯强度（124 MPa），失效载荷（1397 N），抗弯模量（2818 MPa），维氏显微硬度（20.94 kgf/ mm2）。转换程度（27-95.2%）；磨损损耗(垂直损耗：62 ~ 257 μm；体积损失：0.08-20 mm3)；表面粗糙度（Ra: 2.16 μm）；内部配合（137.26 μm），边缘配合（86.49 μm）；粘接强度（16.97- 24.75 MPa）。细胞反应和细菌粘附表现出生物相容性的差异性，受到后处理方案的影响。结论：3d打印树脂牙冠具有良好的体外力学性能，包括可承受典型咀嚼力的断裂抗力值。研究报告普遍有利的结合强度，可接受的内部和边缘适应。然而，这些材料往往表现出较低的弯曲强度，弹性模量，和硬度相比，研磨树脂对应。
