目的:本范围审查旨在绘制有关口内扫描仪(IOS)在制造桩和核心修复物中的应用的文献。
方法:研究方案可在https://osf.io/ja9xh/获得。这项范围审查遵循了乔安娜·布里格斯研究所的指导方针,报告基于PRISMA-ScR提出的清单。
方法:在PubMed/MEDLINE中进行搜索,WebofScience,Scopus,和灰色文学到2023年8月。
结果:共确认455项研究。筛选后,16项研究被认为适合范围审查。其中,13个是体外研究,两个是病例报告,其中一项是临床研究。评估了用于扫描帖子空间的不同IOS系统,三重奏最普遍,其次是Prismescan。虽然大多数研究没有使用任何口内扫描设备,5项研究报告了扫描帖子的使用.关于保留的结果有利于完全数字化的工作流程。然而,纳入研究的适应性和准确性的结果各不相同,强调标准化方法的重要性。未来的临床研究应该包括IOS系统的变化,后空间深度,扫描仪景深,光照条件,扫描后利用率,操作员经验,扫描时间和策略,并与传统技术进行直接比较。
结论:IOS在获取帖子空间的数字印象方面越来越重要,并为临床医生和研究人员提供有价值的见解。虽然包括研究,主要是在体外,展示了在完全数字化的工作流程中利用IOS系统进行后期和核心修复的有希望的结果,进一步完善的研究,特别是临床试验,由于数据异质性和局限性,建议使用。
结论:此图凸显了现代IOS在全数字化工作流程中的潜力,用于后期和核心恢复。尽管结果很有希望,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后和核心修复中的IOS益处至关重要。
OBJECTIVE: This scoping
review aimed to map the literature on the utilization of intraoral scanners (IOS) in fabricating post and core restorations.
METHODS: 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.
METHODS: Searches were conducted in PubMed/MEDLINE, Web of Science, Scopus, and grey literature up to August 2023.
RESULTS: 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.
CONCLUSIONS: 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.
CONCLUSIONS: 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.
