Achievement and maintenance of implant stability are prerequisites for long- term positive outcomes for osseointegrated implants. Thus, implant stability is the key to clinical success. Currently available clinical methods to determine implant stability and osseointegration are relatively crude and may entail percussing a fixture and abutment with Periotest. Radiographs are of value, but a standardised technique is necessary to ensure repeatability. This investigation was designed to study the application of a test method using resonance requency analysis to make quantitative measurements of the stability and shock transmission to the implant body influenced abutment type, torque force and different materials with superstructure.A threaded type implant (3i ; 3.75 mm diameter, 13. 0 mm length) was mounted in die stone. Conical and UCLA abutments were connected to implant with 5, 10, 20 and 32 Ncm fastening torque force and gold crowns were also affixed. The vibration pattern, vibration … More time and frequency power spectrum were measured by an accelerated pick up sensor which was attached to the crown and Fast Fourier Transform Analyzer. Conical and UCLA abutments obtained same tendency for higher tight force demonstrated short vibration time and high peak frequency area. ANOVA shows significant effects of abutment fastening torque force, types of abutment shape and superstructure engagement (segment and non-segment) for the resonance frequency. Influence of superstructure materials for resonance frequency analysis demonstrated no significant different between PFM, Estenia and cold cure resin crowns on the conical abutment, for vibration time and frequency peak spectrum. But in case of UCLA abutment, superstructure materials for resonance frequency analysis was significantly difference between in PFM with cold cure resin and Estenia with cold cure resin for vibration time and frequency peak spectrum. In concluded the clinical point of view, material selection for the UCLA abutment should be considered in tight bite, parafunction and group functioned occlusion cases. Less

植入物稳定性的成就和维护是骨整合的长期积极结果的先决条件。这是植入物稳定性是临床成功的关键。当前可用的临床方法来确定植入物稳定性和骨整合性相对粗略，可能需要将固定装置和与骨灰息肉的基台打击。 X光片是有价值的，但是必须进行标准化技术来确保重复性。该研究旨在研究使用谐振速率分析的测试方法的应用，以对植入物影响的稳定性和冲击传输进行定量测量，这些植入物影响受影响的基台类型，扭矩力和带有上部结构的不同材料。螺纹类型植入物（3i; 3.75 mm直径，13。0毫米长的3.0 mm长）。锥形和UCLA基台与植入物连接为5、10、20和32 NCM固定扭矩和金冠。振动模式，振动……更多的时间和频率功率谱是通过附着在皇冠上的加速接种传感器和快速的傅立叶变换分析仪来测量的。锥形和UCLA基台获得了相同的较高紧密力的趋势，表现出短时间的振动时间和高峰值频率面积。 ANOVA显示了基台固定扭矩力，基台形状和上部结构参与（段）和非段的显着影响，对谐振频率。上层建筑材料对共振频率分析的影响表明，PFM，埃文妮亚和冷固化树脂冠之间在锥形基台上没有显着差异，对于振动时间和频率峰。但是，如果存在UCLA基台，用于共振频率分析的上层建筑材料在带有冷固化树脂的PFM中有显着差异，并带有冷固化树脂，以振动时间和频率光谱。总而言之，临床的观点，应在紧密咬合，副函数和组功能的闭塞病例中考虑对UCLA基台的材料选择。较少的
