OBJECTIVE: 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.
METHODS: 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.
RESULTS: The stress values of the tooth, implant and their surrounding bone increased when their surrounding bone decreased by bone absorption.
CONCLUSION: The stress values of the tooth, implant and their surrounding bone were closely related with the bone resorption.
