目的:回顾口腔内扫描仪(IOS)技术在种植修复中的应用,强调它们对数字印象准确性的影响,咬合注册,以及植入物支持的修复体的配合。
方法:与种植修复相关的已发表的文章,数字印象的准确性,咬合注册,以及植入物支撑的固定修复体的配合。
方法:选择了三个搜索引擎:Medline/PubMed,EBSCO,还有Cochrane.还进行了手动搜索。
方法:文献检索筛选了相关数据库和期刊,以研究从2018年12月至2023年12月在数字种植体修复工作流程中的IOS应用。纳入标准包括随机对照试验,临床试验,案例系列,体外研究集中在IOS在数字种植修复中的应用。
结论:数字牙科技术利用的增加导致数字种植修复工作流程显著融入临床医生的临床实践。几个变量会影响IOS生成的数字印象的准确性。一般来说,学术论文中的普遍观点是,数字工作流程适用于解决短跨度植入物支持的修复。然而,当涉及到大跨度缺陷时,数字工作流程的准确性仍然是一个有争议的问题。数字咬合注册是工作流程的组成部分。它主要取决于缺陷的大小和位置,扫描策略,解剖牙齿的变化,过度咬伤和其他因素。数字预制植入物修复体的整体配合包括近端,咬合接触以及修复体与植入物连接的准确性。研究方法需要标准化以进一步验证。
结论:在临床实践中,必须对可能影响数字印象准确性和最终假体在种植修复中的适合性的各种因素进行全面和最新的理解。
OBJECTIVE: To review the developments in intraoral scanner (IOS) technologies applied in implant prosthodontics, emphasizing their influence on the accuracy of digital impressions, occlusal registrations, and the fit of implant-supported restorations.
METHODS: A collection of published articles related to implant prosthodontics, the accuracy of digital impressions, occlusal registration, and the fit of implant-supported fixed restorations.
METHODS: Three search engines were selected: Medline/PubMed, EBSCO, and Cochrane. A manual search was also conducted.
METHODS: A literature search screened relevant databases and journals for studies on IOS applications in digital implant prosthodontic workflows from Dec 2018 to Dec 2023. Inclusion criteria encompassed randomized control trials, clinical trials, case series, and in vitro research focused on the use of IOS in digital implant prosthodontics.
CONCLUSIONS: The increased utilization of digital dental technologies has led to significant integration of digital implant prosthodontic workflows into clinicians\' clinical practice. Several variables affect the accuracy of digital impressions generated by IOS. Generally, the prevailing opinion in academic papers is that digital workflows are suitable for addressing short-span implant-supported restorations. However, when it comes to long-span defects, the accuracy of digital workflows is still a matter of debate. Digital bite registration is an integral part of the workflow. It depends mainly on the defect size and location, scan strategy, anatomical tooth variations, overbite and other factors. The overall fit of digitally prefabricated implant restorations comprises of proximal, occlusal contacts and how accurately the restoration connects with implants. Research methodologies need standardization for further validation.
CONCLUSIONS: In clinical practice, it is essential to have a thorough and up-to-date comprehension of various factors that can affect the accuracy of digital impressions and the fit of the final prosthesis in implant prosthodontics.
