Özet
The aim of this study was to examine the stress distributions with three different loads in two
different geometric and threaded types of dental implants by finite element analysis. For this
purpose, two different implant models, Nobel Replace and Nobel Active (Nobel Biocare, Zurich,
Switzerland), which are currently used in clinical cases, were constructed by using ANSYS
Workbench 12.1. The stress distributions on components of the implant system under three
different static loadings were analysed for the two models. The maximum stress values that
occurred in all components were observed in FIII (300 N). The maximum stress values occurred in FIII
(300 N) when the Nobel Replace implant is used, whereas the lowest ones, in the case of FI (150 N)
loading in the Nobel Active implant. In all models, the maximum tensions were observed to be in
the neck region of the implants. Increasing the connection between the implant and the bone
surface may allow more uniform distribution of the forces of the dental implant and may protect
the bone around the implant. Thus, the implant could remain in the mouth for longer periods.
Variable-thread tapered implants can increase the implant and bone contact.
