DESCRIPTION (provided by applicant): Intraoral three-dimensional (3D) imaging capability promises to revolutionize traditional dental practice workflow by allowing chairside real-time 3D digital model acquisition without taking traditional impressions, thus facilitating speedy and accurate computer-aided-design (CAD) and computer-aided- manufacturing (CAM) of dental restorations at dentist's office or off-site labs. The 3D imaging technology leads to a new era of digital dentistry. However, bulky form factor and lack of flexibility are among general shortcomings for both 2D and 3D intraoral camera products: bulky sizes of distal probe and handheld units limit their access of entire treatment regions; and their designs usually have rigid structure, preventing their uses in confined spaces and difficult to access areas. The primary objective of this SBIR is to develop and demonstrate a novel 3D imaging approach that enables simultaneous 2D and 3D surface imaging capability for intraoral camera based on the ultrathin fiber scanning concept. The ultrathin intraoral 3D camera (UT3D) we propose herein has several unique features that are far-superior to any existing intraoral cameras: ultrathin (~1 mm), flexible, high resolution 2D/3D (megapixels), accurate and user-friendly for intraoral imaging. This novel 3D technology and product would enable a new level of imaging capability, accessibility, patient comfort, and versatile uses for CAD/CAM applications. With its ultrathin and flexible features, this novel 3D camera can also serve as the "Eye-On-The- Tip" for many dental instruments. The tiny distal end and flexibility allow the ultrathin camera to access areas of undercuts, relief, shear walls/sides that are impossible for traditional optical imaging cameras to access. Our Phase I specific aims are: Aim 1: Design and build a Phase 1 prototype of the ultrathin intraoral 3D camera; Aim 2: Develop, validate and implement the 3D imaging algorithms for the ultrathin intraoral 3D camera; Aim 3: Perform 3D imaging tests on phantom and real teeth to quantify UI3D camera's performance; Aim 4: Identify areas of improvement based on Phase 1 results, and develop/optimize Phase 2 work plan.

描述（由申请人提供）：口内三维 (3D) 成像功能有望彻底改变传统牙科诊所工作流程，允许在椅旁实时获取 3D 数字模型，而无需采用传统印模，从而促进快速、准确的计算机辅助设计 (CAD) ）以及在牙医办公室或场外实验室进行牙科修复体的计算机辅助制造（CAM）。 3D成像技术引领数字牙科新时代。 然而，笨重的外形和缺乏灵活性是 2D 和 3D 口腔内窥镜产品的普遍缺点：远端探头和手持装置的体积庞大限制了它们进入整个治疗区域；它们的设计通常具有刚性结构，妨碍它们在有限空间和难以进入的区域中使用。 该 SBIR 的主要目标是开发和演示一种新颖的 3D 成像方法，该方法能够实现基于超细光纤扫描概念的口腔内窥镜同时 2D 和 3D 表面成像功能。我们在此提出的超薄口腔内 3D 相机 (UT3D) 具有几个远远优于任何现有口腔内相机的独特功能：超薄（~1 毫米）、灵活、高分辨率 2D/3D（百万像素）、精确且用户友好口内成像。这种新颖的 3D 技术和产品将使 CAD/CAM 应用的成像能力、可访问性、患者舒适度和多功能用途达到新的水平。凭借其超薄和灵活的特点，这款新颖的 3D 相机还可以充当许多牙科器械的“尖端之眼”。微小的远端和灵活性使超薄相机能够进入传统光学成像相机无法进入的底切、浮雕、剪力墙/侧面区域。我们第一阶段的具体目标是： 目标 1：设计并构建超薄口腔内 3D 相机的第一阶段原型；目标2：开发、验证和实现超薄口腔内3D相机的3D成像算法；目标3：对模型和真牙进行3D成像测试，量化UI3D相机的性能；目标 4：根据第一阶段的结果确定需要改进的领域，并制定/优化第二阶段的工作计划。
