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.

项目摘要 Cyber​​dontics正在通过开发一种新颖的口腔内扫描仪来彻底改变牙科行业 负担得起，高效的牙科护理。美国牙科服务市场的价值为1009亿美元，但仅 60％的美国人寻求专业牙科护理。在拜访牙齿的患者中，他们接受理想的牙齿 治疗计划仅28％。患者减少护理的主要原因是成本， 多次牙科约会的不便，患者认为他们的口腔健康状况良好 他们没有，并且确保不同意需要护理的需求。通常出于这些原因避免牙医 导致牙齿疾病进展，牙周疾病和其他口腔问题，这会影响患者 系统健康。因此，迫切需要降低护理成本，缩短访问并帮助患者 并确保了解患者有牙齿问题，因此他们可以接受护理。 Cyber​​dontics正在适应 光学相干断层扫描（OCT），一种快速，非离子化且高度敏感和特定的方法，用于牙齿 通过创建具有具有超快速的框架捕获时间3D扫掠源（SS）OCT OCT扫描仪的应用 可用性可与当今的口腔内表面扫描仪相当。这将取代当前的OCT技术，这是 不适合牙科诊所，因为它们较慢，更多的参与和较少准确。 Cyber​​dontics致力于 提供可访问有效的牙科护理。 在直接到II阶段提案的直接中，Cyber​​dontics将开发其超快速的框架捕获时间3D SS-OCT 扫描仪通过提高其性能和有效性。他们将升级激光，数字化器和处理 管道以及评估和优化各种算法以提高扫描的准确性。此外， 他们将对人类受试者进行测试，以将扫描仪的性能与传统方法进行比较 并评估其在指导尺寸冠的放置方面的有效性。完成这项工作后， Cyber​​dontics将有充分的位置购买其创新成像解决方案的商业化。
