| Outline of Final Research Achievements |
We have studied in the three-dimensional finite element method for the stress at the time of bonding the post with keeper in the tooth root. As a result, regardless of the inclination of the abutment, if there is a cement space, post-conditioned keeper body and root dentin stress leading to fracture was found not to occur. Also, partial post in contact with the dentine, the destruction of the adhesive and dentin of the keeper portion side is present, the fatigue fracture with little side load that occurs found.
It focused on the form of the neck portion of the post with keeper was examined whether any change in stress generated by changing the form of the neck portion occurs.
