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 Cyberdontics正在通过开发一种新的口内扫描仪来彻底改变牙科行业， 经济实惠和高效的牙科护理。美国的牙科服务市场价值1090亿美元，但只有 60%的美国人寻求专业的牙科护理。在看牙医的病人中，他们接受理想的牙科 只有28%的治疗计划。病人拒绝护理的主要原因是成本， 多次和漫长的牙科预约的不便，患者认为他们有良好的口腔健康， 他们不这样做，保险公司也不同意护理的需要。出于这些原因，牙医通常 导致牙病进展、牙周病和其他口腔问题， 系统健康。因此，迫切需要降低护理成本，缩短就诊时间，帮助患者 保险公司了解病人有牙齿问题，所以他们可以接受护理。电子牙科学正在适应 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牙科成像方法， 通过创建超快速帧捕获时间3D扫频源（SS）OCT口内扫描仪， 可用性可与当今的口内表面扫描仪相媲美。这将取代目前的OCT技术， 不适应牙科诊所，因为他们更慢，更复杂，更不准确。Cyberdontics致力于 提供方便和有效的牙科护理。 在这个直接进入第二阶段的提案中，Cyberdontics将开发他们的超快帧捕获时间3D SS-OCT 扫描仪通过提高其性能和有效性。他们将升级激光器、数字化仪和加工设备 流水线，以及评估和优化各种算法，以提高扫描的准确性。此外，本发明还 他们将对人体进行测试，以比较他们的扫描仪与传统方法的性能。 并评估其在指导龈下冠修复中的有效性。这项工作完成后， Cyberdontics将有能力追求其创新成像解决方案的商业化。
