Intraoral scanners (IOSs) have emerged as a cornerstone technology in digital dentistry. This article examines the recent advancements and multifaceted applications of IOSs, highlighting their benefits in patient care and addressing their current limitations. The IOS market has seen a competitive surge. Modern IOSs, featuring continuous image capture and advanced software for seamless image stitching, have made the scanning process more efficient. Patient comfort with IOS procedures is favorable, mitigating the discomfort associated with conventional impression taking. There has been a shift toward open data interfaces, notably enhancing interoperability. However, the integration of IOSs into large dental institutions is slow, facing challenges such as compatibility with existing health record systems and extensive data storage management. IOSs now extend beyond their use in computer-aided design and manufacturing, with software solutions transforming them into platforms for diagnostics, patient communication, and treatment planning. Several IOSs are equipped with tools for caries detection, employing fluorescence technologies or near-infrared imaging to identify carious lesions. IOSs facilitate quantitative monitoring of tooth wear and soft-tissue dimensions. For precise tooth segmentation in intraoral scans, essential for orthodontic applications, developers are leveraging innovative deep neural network–based approaches. The clinical performance of restorations fabricated based on intraoral scans has proven to be comparable to those obtained using conventional impressions, substantiating the reliability of IOSs in restorative dentistry. In oral and maxillofacial surgery, IOSs enhance airway safety during impression taking and aid in treating conditions such as cleft lip and palate, among other congenital craniofacial disorders, across diverse age groups. While IOSs have improved various aspects of dental care, ongoing enhancements in usability, diagnostic accuracy, and image segmentation are crucial to exploit the potential of this technology in optimizing patient care.

口内扫描仪的最新进展


口内扫描仪 （IOS） 已成为数字牙科的基石技术。本文研究了 IOS 的最新进展和多方面应用，强调了它们在患者护理中的好处并解决了它们目前的局限性。IOS 市场的竞争激增。现代 IOS 具有连续图像捕获和用于无缝图像拼接的高级软件，使扫描过程更加高效。患者对 IOS 程序的舒适度是有利的，减轻了与传统印模相关的不适。已经向开放数据接口转变，特别是增强了互操作性。然而，IOS 与大型牙科机构的集成速度很慢，面临着与现有健康记录系统的兼容性和广泛的数据存储管理等挑战。IOS 现在已超越了它们在计算机辅助设计和制造中的使用，软件解决方案将它们转变为诊断、患者沟通和治疗计划的平台。一些 IOS 配备了龋齿检测工具，采用荧光技术或近红外成像来识别龋齿病变。IOS 有助于定量监测牙齿磨损和软组织尺寸。为了在口内扫描中精确分割牙齿，这对正畸应用至关重要，开发人员正在利用基于深度神经网络的创新方法。基于口内扫描制造的修复体的临床性能已被证明与使用传统印模获得的修复体相当，证实了 IOS 在修复牙科中的可靠性。 在口腔颌面外科手术中，IOS 可增强印模期间的气道安全，并有助于治疗不同年龄组的唇裂和腭裂等疾病以及其他先天性颅面疾病。虽然 IOS 改善了牙科护理的各个方面，但可用性、诊断准确性和图像分割的持续增强对于利用该技术在优化患者护理方面的潜力至关重要。
