Abstract
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.
