    Abstract: 對於缺牙患者,植牙手術已逐漸成為受歡迎且被採用的療法。骨整合的好壞直接反映了植體穩固度,因此建立提供牙醫師客觀評估骨整合對於手術的成功與否非常重要。
    ;Dental implantation has become a popular treatment procedure for edentulous patients. Osseointegration is a direct connection between an ordered, living bone, and it directly reflects dental implant stability. Therefore, it is important to establish an assessment of implant stability.
    Based on resonance frequency analysis (RFA), the objective of this thesis is to device with non-contact detection technique to quantify the stability of implants. Vibro-acoustic detection technique is developed on acoustic excitation and displacement sensor. The initial validation for prototype device’s performance was conducted by TestPeg and previous designated cases. A commercial product, Osstell®, has high correlation of determination between our detection device. To verify the feasibility for the technique, especially detecting the variation of implant osseointegration stability in healing process. Interface-tissue made from different mixing ratios of epoxies and casted in artificial bone blocks was used to mimic different phases of osseointegration in in-vitro experimentation. Besides, animal trails via rabbits were conducted to observe osseointegration in live bodies.
    In-vitro experiment results show that the frequencies in MD measurements increase as mixing ratio getting higher except for one case. The reason which makes the trend changeful in BL measurements comes from the fixing condition. In in-vivo experiment, the results show that secondary stability dominates stability after stability dip and increases as time passing. Primary stability influences success of following adaptation.
    Although the convenience for handling the prototype probe in measurement is still needed to improve. The vibro-acoustic detection technique is still practical because it reflects real clinical conditions in in-vivo experiments. In conclusion, the technique is indeed feasible for monitoring osseointegration of the dental implant stability during healing process.
