Abstract
In order to verify what effects bridges have on abutment teeth movement during mastication, we first measured the movements of each abutment tooth separately and compared those results to when they were used as bridge abutments.
The results were as follows;
1. When a constant force was applied to the individual abutment teeth, a buccolingual movement was recorded. However, this movement was drastically reduced when used as bridge abutments. No particular movement was recorded in the vertical direction.
2. Compared to the individual abutment teeth, the bridge abutments showed a reduction in the buccolingual and vertical movements when biting down on some test food products.
3. The level of reduction in the amount of movement varied depending upon the person.
