THREE-DIMENSIONAL FINITE ELEMENT STRESS ANALYSIS OF SKY IMPLANT SYSTEM

The objective of this study was to evaluate the stress on the cortical bone around few body dental implants using SKY system components with different angled abutments position. These angled abutments have been especially developed for primary structures to allow fast fabrication of occlusal screw-retained temporaries for immediate treatment of patients. Stress levels on these implants were analyzed through finite element analysis. The results showed displacement and effective stress distribution for SKY implants with 90 and 35 degrees position inside jawbone. The 35 degree angled type of implant generated lower von Mises stress in the cortical bone under normal loading of 100 N in comparison with 90 degree angled implant under 50 N loading. The study performed showed the importance of dental implant angled position on the occlusion load transfer mechanism. It was concluded that the high stress gradients can be avoided by different angle position of implants, which can provoke the implant surrounding bone tissue fracture.
