This Small Business Technology Transfer (STTR) Phase I aims to develop a novel method for monitoring dental implant stability. The system aims to provide a low cost temporary method for dentists to quantitatively assess the 27 million dental implants globally placed per year. These implants currently have a 10-15% failure rate. The proposed system provides mechanical feedback on the bond stability between the implant and the surrounding bone that serves as a foundation for the crown and receives bite loads. This bond stability provides direct, actionable information that may be superior to current subjective evaluations used by dentists including feel with their hands, X-Ray, or torqueing.This Small Business Technology Transfer (STTR) Phase I project aims to complete a proof of concept demonstration of a reliable and accurate device to measure the stability of dental implants using vibrational technology. The proposed system seeks to provide controlled forces to the implant in order to sense the degree of motion and stability. This new technology has two critical concepts: the first is to quantify implant stability via angular stiffness at the gum line of the implant bone (i.e., the ability against rotation), and the second is the development of a clip-on sensor unit and a mechanics-based model to calculate implant stability. This project seeks to develop a prototype with a design validated on in vitro mandible models.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

小企业技术转让（STTR）第一阶段旨在开发一种监测牙科种植体稳定性的新方法。该系统旨在为牙医提供一种低成本的临时方法，以定量评估全球每年放置的2700万个牙科种植体。 这些植入物目前有10-15%的失败率。所提出的系统提供关于种植体和周围骨之间的结合稳定性的机械反馈，所述周围骨用作牙冠的基础并接收咬合载荷。 这种粘结稳定性提供了直接的、可操作的信息，可能上级目前牙医使用的主观评估，包括手感、X光或扭矩。这个小企业技术转让（STTR）第一阶段项目旨在完成一个可靠和准确的设备的概念验证演示，该设备使用振动技术测量牙科种植体的稳定性。所提出的系统试图向植入物提供受控的力，以便感测运动和稳定性的程度。 这种新技术有两个关键概念：第一个是通过种植体骨的牙龈线处的角刚度来量化种植体稳定性（即，抗旋转能力），第二个是开发夹式传感器单元和基于力学的模型，以计算植入物稳定性。 该项目旨在开发一种原型，其设计在体外下颌骨模型上得到验证。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
