Abstract
In order to secure the initial fixation for implanting an implant, obtaining mechanical
interdigitations between the implant and a bone is a critical element. For that reason, at the
initial fixation of the implanted implant, understanding the stress distribution on the implant
and jawbone is clinically necessary.
In this research, we fabricated CAD data based on the actual CT images, and by using the
finite element method, we examined the stresses generated in the jawbone and implant
during the initial fixation of the implant by the SAT (Step Adaptation Technique) method. We
fabricated two types of analysis models: normal drill hole and the SAT method, and
reproduced it on CAD. As a result of the finite element analysis, by using the SAT method,
the stresses were increased by about five times the maximum on the jawbone and about six
times the maximum on the implant compared to the normal drill hole. This suggests that the
SAT method is an effective method for securing the initial fixation of the implant.
