This scoping review aimed to map the literature on the utilization of intraoral scanners (IOS) in fabricating post and core restorations.
The study protocol is available at https://osf.io/ja9xh/. This scoping review followed Joanna Briggs Institute guidelines, and reporting was based on the checklist proposed by PRISMA-ScR.
Searches were conducted in PubMed/MEDLINE, Web of Science, Scopus, and grey literature up to August 2023.
A total of 455 studies were identified. After screening, 16 studies were deemed suitable for scoping review. Of these, 13 were in vitro studies, two were case reports, and one was a clinical study. Different IOS systems for scanning post spaces were evaluated, with Trios being most prevalent, followed by Prismescan. While most studies did not use any intraoral scanning devices, five studies reported the use of scan posts. Results regarding retention favored fully digital workflows. However, results about the adaptation and accuracy varied between included studies, highlighting the importance of standardized approaches. Future clinical studies should encompass variations in IOS systems, post space depths, scanner depth of field, light conditions, scan post utilization, operator experience, scanning time and strategy, and direct comparison with conventional techniques.
IOS is increasingly important in capturing digital impressions for post spaces and provides valuable insights for clinicians and researchers. Although included studies, primarily in vitro, demonstrated promising results for the utilization of IOS systems in fully digital workflows for post and core restorations, further well-conducted studies, particularly clinical trials, are recommended due to data heterogeneity and limitations.
This mapping highlights the potential of modern IOS in fully digital workflows for post and core restorations. Despite promising results, challenges related to different variables associated with IOS require careful consideration. Standardization and additional clinical validation are essential for optimize IOS benefits in post and core restorations.
本范围综述旨在绘制关于使用口内扫描仪（IOS）制作桩核修复体的文献图谱。
研究方案可在 https://osf.io/ja9xh/ 获取。本范围综述遵循乔安娜·布里格斯研究所指南进行，报告依据 PRISMA-ScR 提出的清单进行。
截至 2023 年 8 月，在 PubMed/MEDLINE、Web of Science、Scopus 和灰色文献中进行了搜索。
共确定了 455 项研究。经过筛选，认为 16 项研究适合进行范围综述。其中，13 项为体外研究，2 项为病例报告，1 项为临床研究。评估了用于扫描桩腔的不同 IOS 系统，其中最常见的是 Trios，其次是 Prismescan。虽然大多数研究未使用任何口内扫描设备，但有 5 项研究报告使用了扫描桩。关于保留力的结果倾向于完全数字化工作流程。然而，纳入研究之间的结果关于适应性和准确性存在差异，突出了标准化方法的重要性。未来的临床研究应包括 IOS 系统、桩腔深度、扫描仪景深、光照条件、扫描桩使用、操作人员经验、扫描时间和策略的变化，并与传统技术进行直接比较。
IOS 在捕获桩腔的数字印模方面变得越来越重要，为临床医生和研究人员提供了有价值的见解。尽管纳入的研究主要是体外研究，但表明在桩核修复的完全数字化工作流程中使用 IOS 系统具有很大潜力，鉴于数据异质性和局限性，建议进行更多精心设计的研究，特别是临床试验。
该图谱突出了现代 IOS 在桩核修复的完全数字化工作流程中的潜力。尽管取得了有希望的结果，但与 IOS 相关的不同变量相关的挑战需要仔细考虑。标准化和额外的临床验证对于优化 IOS 在桩核修复中的益处至关重要。
