Abstract
We performed a computer analysis of the change and stress on pedodontic treatment using the finete element method. In this study, we investigated the effects of the crown-distal shoe, abutment deciduous teeth, periodental tissues and per manent tooth germs on the occlusal forces when we inserted of the crown-distal shoe.
The following results were obtained.
1) We found that the crown-distal shoe was displaced disto-downwardly when pressed by the occlusal forces. The displacement of the distal end of shoe was especially large.
2) We found that the stress was highest on the contact point of the crown and distal shoe when pressed by the occlusal forces.
3) The nearer the pressed position on the shoe the contact point of crown and distal shoe was, the lower the displacement and stress were made.
4) We feel that the full cast of the crown-distal shoe better than the crown-distal shoe soldered crown and shoe because of less falling, breakage and deformation of the crown-distal shoe.
