项目摘要

In order to carry out the functional evaluation of the dental implantation objectively, we have interested in the implant movement. The purpose of this study is to develop the functional assessment system for dental implant usable at the dental-chair side and to establish the index of functional assessment of the implant. We have newly developed the system in which the implant movement can be measured just after implanting to jaw bone throughout the long term and the quality of the implant operation, evaluations of the prognosis, the effects of the connection with the natural tooth, etc.can be also considered, from the functional viewpoints of the implant.This research has been made for three years. In the first year, the standard models which simulated the movement of dental implant were made. And the measurement conditions suitable for the clinical use were examined. The functional assessment system for dental implant IAD101 and the measurement probe IAP1 were designed and produced e … More xperimentally. In the second year, the above developed system and probe and the index of functional assessment were examined. The medical safety and human interface of the probe were also examined. Finally, IAD201 and IAP2 were designed and made experimentally. In addition, the implant geometry (length and diameter) as the criteria of implant selection was also discussed by using this system and probe. In the last year, the experimental system and probe was also examined. The measuring frequency was expanded to 5000Hz in order to obtain the more accurate index of functional assessment and the tip of the probe was also miniaturized in order to improve the operability in the clinical use. Finally, the IAD301 and IAP3 were made and synthetically evaluated for clinical use, then the development of the system has been completed. The developed system will overcome various disadvantages of marketed Periotest^<TM> and Osstell^<TM>, enable the objective assessment of implantation instead of morphological radiographic examination and the manual examination, and be very effective for the evaluation of the prognosis. Moreover it will be useful in the selection of the implant geometry. Less

为了客观地对种植体的功能进行评价，我们对种植体的运动进行了研究。本研究的目的是开发可用于牙椅侧种植体的功能评估系统，并建立种植体的功能评估指标。我们开发了一种新的系统，可以从种植体的功能角度，测量种植体在颌骨上种植后的长期运动，并可以考虑种植体的操作质量、预后评估、与自然牙的连接效果等。这项研究已经进行了三年。第一年，制作了模拟种植体运动的标准模型。并考察了适合临床使用的测量条件。设计并制作了牙种植体功能评估系统IAD101和测量探针IAP1。第二年，对上述开发的系统、探针和功能评价指标进行了检验。对探针的医疗安全性和人机界面进行了检验。最后对IAD201和IAP2进行了实验设计和制作。此外，还讨论了种植体的几何形状（长度和直径）作为种植体选择的标准。去年，实验系统和探测器也进行了检查。将测量频率扩大到5000Hz，以获得更准确的功能评估指标，同时将探头尖端小型化，以提高临床使用中的可操作性。最后制作了IAD301和IAP3并进行了临床综合评价，完成了系统的研制。该系统将克服市售Periotest^<TM>和Osstell^<TM>的种种缺点，能够代替形态x线检查和人工检查对植入物进行客观评估，对预后的评价非常有效。此外，它将有助于种植体几何形状的选择。少
