Abstract In this Phase II SBIR project ASTER Labs will significantly enhance an intuitive, safe, fully-embedded detection and localization solution for lost dentures. This concept was designed and successfully evaluated during Phase I with elderly denture wearers and caregivers, and tested for its accuracy and efficacy via demonstrations of successful localization of the misplaced prostheses in a variety of common environments. For the 35 million Americans, primarily older adults, with no remaining natural teeth, and 178 million with at least one tooth missing, the use of removable dentures has many benefits, including improved mastication, nutritional intake, speech, and appearance, as well as social interaction and emotional confidence. Conversely, misplacing or losing dentures can have significant detrimental effects, including reduced oral functional status, high replacement cost, and emotional stress. Denture use is a complex learned skill and wearers are often unable to easily adapt to replacement dentures, especially if they have worn the previous pair for many years or have conditions affecting neuromuscular function, such as dementia, stroke, or Parkinson's disease. Caregivers in long term care facilities and hospitals commonly report episodes of lost dentures due to the high prevalence of patient disability and dependency on caregivers who may be unfamiliar with properly managing dental prostheses. When dentures are lost—often after being removed and placed on meal trays, in napkins, tissues, or laundry—caregivers and facilities are directly blamed for the loss by patients and their families. While families may ultimately be financially responsible for replacement, these frequent scenarios create immense emotional frustration and potential conflict for all involved. Tagging and location technologies for simple objects (e.g. keys) are available, but typically require power and recharging, posing a risk for patients with dentures inside their mouths. ASTER Labs' novel device is a safe, intuitive, and automated solution based on advanced signal transmission and processing techniques. It provides an on-demand and accurate handheld detector operated by a caregiver to locate a uniquely tuned antenna. The system is fully passive, requiring no power source inside the denture, and is easily encapsulated in the denture base substrate. A user-friendly touchscreen accompanies the handheld detector to guide and assist the caregiver in efficiently searching for and locating the lost denture. The system's purpose is to increase success rates of finding lost dentures, while giving denture wearers, families, and care staff the confidence and peace of mind that these important prostheses can be found if lost, thus minimizing the financial, physical, and emotional consequences of fabricating and adapting to new prostheses. The system design adheres to multiple safety specifications and regulations to ensure patient health and well-being. The multidisciplinary Phase II SBIR team led by ASTER Labs will use advanced signal generation and detection techniques to create a highly unique, but practical technological solution for assuring older adults of regular availability and use of their personal dentures.

摘要 在第二阶段SBIR项目中，ASTER Labs将显着增强直观、安全、全嵌入式检测 以及缺失假牙的定位解决方案。这一概念的设计和成功评估期间， 第一阶段，老年义齿佩戴者和照顾者，并测试其准确性和有效性，通过 在各种常见环境中成功定位错位假体的演示。 对于3500万美国人来说，主要是老年人，没有剩余的天然牙齿， 至少有一颗牙齿缺失，使用可移动假牙有许多好处，包括改善咀嚼， 营养摄入、语言和外表，以及社会交往和情感自信。相反地， 错放或丢失假牙可能具有显著的有害影响，包括口腔功能状态降低， 高重置成本和情绪压力。灵活使用是一项复杂的学习技能， 无法轻易适应替换假牙，尤其是如果他们已经戴了多年的前一副假牙 或患有影响神经肌肉功能的疾病，如痴呆、中风或帕金森病。 长期护理机构和医院的护理人员通常报告由于高风险而丢失假牙的事件。 患者残疾和依赖可能不熟悉正确管理的护理人员的患病率 假牙当假牙丢失时--通常是在被取下并放在餐盘、餐巾纸上后， 纸巾或洗衣护理人员和设施直接造成患者及其家属的损失。 虽然家庭最终可能在经济上负责更换，这些频繁的情况造成 巨大的情感挫折和潜在的冲突。标签和定位技术， 简单的物体（例如钥匙）可用，但通常需要电源和充电，对患者构成风险 嘴里还装着假牙ASTER实验室的新设备是一种安全，直观和自动化的解决方案， 先进的信号传输和处理技术它提供了一个按需和准确的手持 由护理人员操作以定位唯一调谐的天线的探测器。该系统是完全被动的，不需要 电源内置于义齿内部，并易于封装在义齿基托基底中。用户友好 触摸屏伴随着手持探测器，以引导和帮助护理人员有效地搜索 找到丢失的假牙该系统的目的是提高寻找丢失假牙的成功率， 给予假牙佩戴者、家庭和护理人员信心和安心， 如果丢失，可以找到假肢，从而最大限度地减少经济，身体和情感上的后果， 制造和适应新的假肢。系统设计符合多项安全规范， 以确保患者的健康和福祉。由ASTER领导的多学科第二阶段SBIR团队 实验室将使用先进的信号生成和检测技术，创造一个高度独特的，但实用的 确保老年人定期获得和使用个人假牙的技术解决方案。
