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）：口腔内三维（3D）成像能力有望通过允许椅子方实时3D数字模型获取而无需采取传统印象，从而彻底改变传统的牙科练习流程，从而促进快速而准确的计算机辅助设计（CAD（CAD）（CAD） ）和牙医办公室或现场实验室牙科修复体的计算机辅助制造（CAM）。 3D成像技术导致了数字牙科的新时代。 然而，庞大的外形和缺乏灵活性是2D和3D口内相机产品的一般缺点之一：远端探头和手持单元的笨重尺寸限制了它们对整个治疗区域的访问；他们的设计通常具有刚性的结构，从而阻止了它们在狭窄的空间中的用途，并且难以进入区域。 该SBIR的主要目的是开发和演示一种新型的3D成像方法，该方法基于超薄纤维扫描概念，可以同时使用2D和3D表面成像能力。我们在本文提出的超薄端内3D摄像头（UT3D）具有几个独特的功能，这些功能与任何现有的口腔内相机相比较远：超薄（〜1毫米），柔性，高分辨率2D/3D（兆像素），准确且用户友好，可用于口内成像。这种新颖的3D技术和产品将使您可以在CAD/CAM应用中获得新的成像能力，可访问性，患者舒适性和多功能用途。这款新颖的3D摄像头凭借其超薄和灵活的功能，也可以用作许多牙科乐器的“尖端”。远端和柔韧性的微小摄像头可以访问传统光学成像摄像头不可能访问底面，浮雕，剪力墙/侧面的区域。我们的I阶段特定目的是：AIM 1：设计和构建超薄式磁内3D相机的1阶段原型； AIM 2：为超薄的口腔内3D摄像头开发，验证和实施3D成像算法； AIM 3：对幻影和真实牙齿进行3D成像测试，以量化UI3D相机的性能；目标4：根据第1阶段的结果确定改进领域，并制定/优化第2阶段的工作计划。
