Effects of alveolar bone resorption on stress of tooth/implant-supported restoration connected by precision attachment / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of alveolar bone resorption on stress of tooth/implant-supported restoration connected by precision attachment using three-dimensional finite element(FEM) approach.</p><p><b>METHODS</b>The FEM was applied to analyze the stress distribution of tooth/implant-supported restoration connected by precision attachment under various loading conditions when the alveolar bone was absorbed to different level.</p><p><b>RESULTS</b>The stress values of the tooth, implant and their surrounding bone increased when their surrounding bone decreased by bone absorption.</p><p><b>CONCLUSION</b>The stress values of the tooth, implant and their surrounding bone were closely related with the bone resorption.</p>
