The aim of this review was to collect available evidence and evaluate accuracy outcomes of dental implant impression techniques, and to compare the accuracy of conventional implant impression versus digital implant impression. Inclusion and exclusion criteria were defined by the authors before the start of the study. The inclusion criteria were: all studies published in English language; studies no older than five years; analyzing the accuracy of digital vs conventional technique impression on implants. The exclusion criteria were: publications that reported the same data as later publications by the same authors and systematic reviews; commentaries and letters to the editor; case report and case series. The search resulted in 106 titles. Following the first stage of screening, after the records identification through database manual searching, 112 potentially relevant studies were identified. After the second stage screening, 33 full text publications were obtained and analyzed and 17 were excluded. Afterwards, 18 articles resulted eligible after full text reading and a cross search of the articles' references was accomplished; 3 articles were consequently added. At the end only 7 articles were included in the quantitative analysis. Within the limitations of this systematic review, digital impression on dental implants offers a comparable accuracy compared with conventional impressions technique. More clinical trials are recommended to investigate the accuracy of these scanners and their validity in clinical use.
本次综述的目的是收集现有证据并评估牙科种植体印模技术的准确性结果，并比较传统种植体印模与数字种植体印模的准确性。在研究开始之前，作者定义了纳入和排除标准。纳入标准为：所有以英文发表的研究；不超过五年的研究；分析数字与传统技术对种植体印模准确性的影响。排除标准为：报告与同一作者的后续出版物相同数据的出版物，以及系统评价、评论和给编辑的信函、病例报告和病例系列。检索结果共得到 106 个标题。经过数据库手动搜索的第一阶段筛选后，确定了 112 项潜在相关研究。经过第二阶段筛选，获得并分析了 33 篇全文出版物，并排除了 17 篇。之后，经过全文阅读和对文章参考文献的交叉搜索，有 18 篇文章符合条件，随后又增加了 3 篇。最后，只有 7 篇文章被纳入定量分析。在本系统评价的局限性内，数字化印模在牙科种植体方面具有与传统印模技术相当的准确性。建议进行更多的临床试验，以研究这些扫描仪的准确性及其在临床应用中的有效性。
