Abstract
Bioactive glass has a unique trait for binding to bone. Therefore, in order to maintain the bondage for a longer period of time, it is necessary to investigate the stress distribution within the artificial tooth root and surrounding bone tissue. This research deals with analyzing these stress regions using the finite element method.The results were as follows:1. Large amounts of stress were found to be concentrated on the metal core layer of the artificial tooth root. Compared to the metal core layer, the glass layer showed less stress.2. In the surrounding bone tissue, stress appeared to be concentrated along the alveolar ridge and restraining point.3. The effect of the material of the superstructure upon the stress within the artificial tooth root and surrounding bone tissue appeared to be minimal.4. When the width of the mandibular bone was narrow buccolingually, the original stress point tended to move toward an apical direction and increase at the same time.5. When application of force upon the artificial root was not in direction of the tooth axis, the stress factor tended to increase.
