The technology behind optical scanners has greatly improved recently, making their dental application advantageous. While their accuracy is now comparable with that of conventional impression materials, whether these techniques have other advantages is unclear.
The purpose of this systematic review and meta-analysis was to determine whether digital scanning for implant-supported restorations is more time-efficient and convenient for the patient.
The study was conducted on September 23, 2020 using 4 different databases (Medline, Cochrane, Web of Science, Scopus) searching for clinical studies that compared the time needed and/or patient perceptions between those who had undergone the digital scanning procedure and those who had undergone conventional impression making.
Twelve studies met the inclusion criteria for qualitative and quantitative analysis. Outcome variables were measured as standard mean differences (SMDs) by following a fixed-effects model or random-effects model (in the case of high heterogeneity). Digital scanning was more time-efficient and was preferred by patients for all 4 analyzed outcomes (comfort, anxiety, nausea, time perception).
Digital scanning was found to be more time-efficient and convenient than conventional impression making for implant-supported restorations. Additional randomized controlled trials are needed to confirm the findings of this review.
光学扫描仪的技术最近有了很大的改进，使其在牙科方面的应用具有优势。虽然它们的准确性现在可以与传统的印模材料相媲美，但这些技术是否具有其他优势尚不清楚。
本系统评价和荟萃分析的目的是确定数字化扫描在种植体支持修复方面是否更省时、更方便患者。
该研究于 2020 年 9 月 23 日使用 4 个不同的数据库（Medline、Cochrane、Web of Science、Scopus）进行，搜索比较数字化扫描程序和传统印模制作之间所需时间和/或患者感受的临床研究。
12 项研究符合定性和定量分析的纳入标准。根据固定效应模型或随机效应模型（在高度异质性的情况下），将结果变量测量为标准均数差（SMD）。数字化扫描在所有 4 个分析结果（舒适度、焦虑、恶心、时间感知）方面都比传统印模制作更省时，也更受患者欢迎。
数字化扫描在种植体支持修复方面比传统印模制作更省时、更方便。需要更多的随机对照试验来证实本综述的发现。
