When a natural tooth connected to an implant abutment by a framework is displaced within physiologic limits under functional loads, the superstructure acts as a cantilever moment arm and the implant is loaded additionally during that moment effect. The effects of a deflecting support connected to an IMZ implant, with either the IMC resilient or the titanium rigid element, were evaluated through an experimental model. The strain values measured when the moment arm was not allowed to deflect were only 30% lower than the strains measured when it was deflected within the limits of physiologic tooth mobility. The IMC was effective and achieved a reduction in the cervical strains up to 60% when compared with the rigid connector.
当通过框架与种植体基台相连的天然牙在功能负荷下在生理限度内移位时,上部结构充当悬臂弯矩臂,并且在该弯矩作用期间种植体受到额外加载。通过一个实验模型评估了与IMZ种植体相连的具有IMC弹性元件或钛刚性元件的挠曲支撑的效果。当弯矩臂不允许挠曲时测得的应变值仅比在生理牙齿动度限度内挠曲时测得的应变低30%。与刚性连接体相比,IMC是有效的,并且能使颈部应变降低多达60%。
