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 drasticallv reduced when used as bridge abutments. No particular movement was recorded in the vertical direction. 2. Compared to tire individual abutrnent teeth, the bridge abutments showed a reduction in the buccolinzual and vertical movements when biting down on sonae test food products. 3. The level of reductiorn in the amount of movement varied depeuading upon the person.
