Developing an Optical Coherence Tomography (OCT) based handheld intraoral scanner for dentistry

项目总结 Cyberdontics正在通过开发一种新型的口腔内扫描仪来彻底改变牙科行业，该扫描仪将能够 负担得起的高效的牙科护理。美国的牙科服务市场价值1090亿美元，但仅 60%的美国人寻求专业的牙科护理。在去看牙医的患者中，他们接受理想的牙科 治疗计划只有28%的时间。患者拒绝接受治疗的主要原因是费用、 不方便多次和冗长的牙科预约，当患者认为他们的口腔健康良好时 他们没有，保险公司也不同意护理的必要性。出于这些原因通常不去看牙医 导致牙病进展、牙周病和其他影响患者的口腔问题 全身性健康。因此，迫切需要降低护理成本，缩短就诊时间，帮助患者 保险公司了解患者有牙科问题，因此他们可以接受护理。赛伯登斯正在适应 光学相干断层扫描(OCT)是一种快速、非电离的、高度敏感和特异的牙科检查方法 通过创建超快的帧捕获时间3D扫描源(SS)OCT口腔内扫描仪 可用性可与当今的口腔表面扫描仪相媲美。这将取代目前的OCT技术，后者是 不适应牙科诊所，因为他们速度慢，更复杂，更不准确。Cyberdontics致力于 提供无障碍和有效的牙科护理。 在这份直接到第二阶段的计划中，Cyberdontics将开发他们的超快帧捕获时间3D SS-OCT 通过提高扫描仪的性能和效率。他们将升级激光、数字化仪和处理 流水线，以及评估和优化各种算法，以提高扫描的准确性。另外， 他们将在人体受试者身上进行测试，将扫描仪的性能与传统方法进行比较 并评价其在指导龈下冠放置方面的有效性。在这项工作完成后， Cyberdontics将处于有利地位，可以将他们的创新成像解决方案商业化。

PROJECT SUMMARY Cyberdontics is revolutionizing the dental industry by developing a novel intraoral scanner that will enable affordable and efficient dental care. The market for dental services in the US is valued at $109 billion, but only 60% of Americans seek professional dental care. Of the patients that visit a dentist, they accept the ideal dental treatment plan only 28% of the time. The main reasons cited for patients declining care are cost, the inconvenience of multiple and lengthy dental appointments, patients believing they have good oral health when they do not, and insurers not agreeing with the need for care. Avoiding the dentist for these reasons usually results in dental disease progression, periodontal disease, and other oral problems, which impact patient systemic health. Therefore, there is a critical need to reduce the cost of care, shorten visits, and help patients and insurers understand the patient has a dental problem so they can accept care. Cyberdontics is adapting optical coherence tomography (OCT), a fast, non-ionizing, and highly sensitive and specific approach, for dental applications by creating an ultra-fast frame-capture-time 3D swept source (SS) OCT intraoral scanner that has usability comparable to today’s intraoral surface scanners. This will replace current OCT techniques, which are not adapted to the dental clinic as they slower, more involved, and less accurate. Cyberdontics is committed to providing accessible and effective dental care. In this Direct to Phase II proposal, Cyberdontics will develop their ultra-fast frame-capture-time 3D SS-OCT scanner by increasing its performance and effectiveness. They will upgrade the laser, digitizer, and processing pipeline, as well as evaluate and optimize various algorithms to improve the accuracy of the scan. Additionally, they will conduct tests on human subjects to compare the performance of their scanner to traditional methods and assess its effectiveness in guiding the placement of subgingival crowns. Upon completion of this work, Cyberdontics will be well-positioned to pursue commercialization of their innovative imaging solution.
