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.

项目概要 Cyber​​dontics 正在通过开发一种新型口腔内扫描仪来彻底改变牙科行业，该扫描仪将使 美国牙科服务市场价值 1,090 亿美元，但价格低廉且高效。 60% 的美国人寻求专业牙科护理，在去看牙医的患者中，他们接受理想的牙科护理。 治疗计划仅占 28% 患者拒绝护理的主要原因是费用、 多次和长时间的牙科预约带来的不便，患者相信自己的口腔健康状况良好 他们不这样做，保险公司也不同意需要护理 通常因为这些原因而避免去看牙医。 导致牙齿疾病进展、牙周病和其他口腔问题，从而影响患者 因此，迫切需要降低护理成本、缩短就诊时间并帮助患者。 保险公司了解患者有牙齿问题，因此他们可以接受 Cyber​​dontics 正在调整的护理。 光学相干断层扫描 (OCT) 是一种快速、非电离、高灵敏度和特异性的方法，适用于牙科 通过创建超快速帧捕获时间 3D 扫频源 (SS) OCT 口腔内扫描仪来开发应用程序 可用性可与当今的口腔内表面扫描仪相媲美，这将取代当前的 OCT 技术。 不适合牙科诊所，因为它们速度较慢、涉及性更强且准确性较低。 提供方便且有效的牙科护理。 在这个直接进入第二阶段的提案中，Cyber​​dontics 将开发其超快帧捕获时间 3D SS-OCT 他们将通过提高扫描仪的性能和效率来升级激光、数字化仪和处理。 管道，以及评估和优化各种算法以提高扫描的准确性。 他们将对人体进行测试，以将扫描仪的性能与传统方法进行比较 并评估其在放置龈下引导牙冠方面的有效性。 Cyber​​dontics 将处于有利地位，致力于实现其创新成像解决方案的商业化。
