A systematic review of the effect of different factors on the accuracy of additively manufactured (AM) interim dental prostheses is lacking.
The purpose of this systematic review was to identify potential factors that may affect the accuracy of AM interim dental prostheses.
The review adhered to the guidelines outlined in the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. The protocol was registered in the international prospective database of systematic reviews (PROSPERO) (CRD42024521564). The risk of bias in the included studies was assessed by using the Joanna Briggs Institute (JBI) checklist. Two reviewers performed an electronic search on the Web of Science, Scopus, PubMed, and Embase databases for articles published up to the end of 2023.
The electronic search resulted in 406 studies. After removing duplicates, 205 studies remained. Thirty-one studies (30 in vitro and 1 in vivo) were included and categorized into 6 types: AM material (type and composition), prosthetic factor (tooth type, restoration size, finish line, abutment taper), AM system (technique and printer), AM parameters (layer thickness, printing orientation), postprocessing (rinsing, postpolymerization), and aging.
The accuracy of AM interim dental prostheses is affected by factors that include the AM material, prosthetic factors, the AM system, the AM parameters, postprocessing, and aging.
目前缺乏对不同因素对增材制造（AM）临时牙修复体精度影响的系统评价。
本系统评价的目的是确定可能影响AM临时牙修复体精度的潜在因素。
本评价遵循系统评价与Meta分析的首选报告项目（PRISMA）声明中概述的指南。该方案已在国际前瞻性系统评价数据库（PROSPERO）（CRD42024521564）中注册。采用乔安娜·布里格斯研究所（JBI）清单评估纳入研究的偏倚风险。两名评价者在Web of Science、Scopus、PubMed和Embase数据库中对截至2023年底发表的文章进行了电子检索。
电子检索得到406项研究。去除重复项后，剩余205项研究。纳入31项研究（30项体外研究和1项体内研究），并分为6类：AM材料（类型和成分）、修复因素（牙型、修复体尺寸、边缘线、基牙锥度）、AM系统（技术和打印机）、AM参数（层厚、打印方向）、后处理（冲洗、后聚合）和老化。
AM临时牙修复体的精度受多种因素影响，包括AM材料、修复因素、AM系统、AM参数、后处理和老化。
