Abstract

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) 已成为数字牙科的一项基础技术。本文探讨了口内扫描仪的最新进展和多方面应用,强调了其在患者护理方面的优势,并探讨了其目前存在的局限性。IOS 市场竞争激烈。现代的 IOS 具有连续图像捕捉功能和先进的无缝图像拼接软件,使扫描过程更加高效。患者对 IOS 程序的舒适度很高,减轻了传统取模带来的不适感。目前已转向开放式数据接口,显著提高了互操作性。然而,IOS 与大型牙科机构的整合进展缓慢,面临着与现有健康记录系统的兼容性和大量数据存储管理等挑战。目前,综合观测系统已不仅仅局限于用于计算机辅助设计和制造,软件解决方案已将其转化为诊断、患者交流和治疗规划的平台。一些 IOS 配备了龋病检测工具,利用荧光技术或近红外成像技术来识别龋损。口内观察系统有助于对牙齿磨损和软组织尺寸进行定量监测。对于口内扫描中的精确牙齿分割(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。事实证明,根据口内扫描制作的修复体的临床性能可与使用传统印模获得的修复体相媲美,这证明了 IOS 在牙科修复中的可靠性。在口腔颌面外科,IOS 提高了取模过程中气道的安全性,并有助于治疗唇腭裂等不同年龄段的先天性颅面疾病。虽然 IOS 改善了牙科护理的各个方面,但要发挥这项技术在优化患者护理方面的潜力,还必须不断提高其可用性、诊断准确性和图像分割能力。
