Abstract

Background/Objectives: This systematic review and meta-analysis aimed to compare the mechanical and surface properties of three-dimensional (3D) printed and conventionally polymerized acrylic resins. Methods: A comprehensive search of four electronic databases (PubMed, Embase, Scopus, and Web of Science) was conducted to identify in vitro studies evaluating impact strength, elastic modulus, surface hardness, and surface roughness. Study quality was assessed using design-specific evaluation tools. When sufficient homogeneous data were available, a meta-analysis was performed. Results: The initial search yielded 942 potentially relevant records. Fifteen studies met the criteria for qualitative synthesis, and 13 were included in the meta-analysis. All studies were in vitro and were rated as having moderate to high methodological quality. Conclusions: Although conventional acrylic resins currently demonstrate superior mechanical strength, 3D-printed materials exhibit comparable surface properties and continue to evolve rapidly. Additive manufacturing technologies show promise as a viable and effective alternative for future prosthodontic applications.

牙科3D打印增材生产丙烯酸的特点：机械参数和表面参数的比较-对新报告的荟萃分析的系统回顾。

背景/目的：本系统综述和荟萃分析旨在比较三维（3D）打印和常规聚合丙烯酸树脂的机械和表面性能。方法：对四个电子数据库（PubMed, Embase， Scopus和Web of Science）进行全面检索，以确定评估冲击强度，弹性模量，表面硬度和表面粗糙度的体外研究。使用特定设计的评估工具评估研究质量。当有足够的同质数据可用时，进行荟萃分析。结果：最初的搜索产生了942条可能相关的记录。15项研究符合定性综合标准，13项纳入meta分析。所有的研究都是在体外进行的，并被评为具有中等到高的方法学质量。结论：虽然传统的丙烯酸树脂目前表现出优越的机械强度，但3d打印材料表现出类似的表面性能，并继续快速发展。增材制造技术有望成为未来修复应用的可行和有效的替代方案。

期刊介绍： Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
