Abstract

In the lower denture, fracture occurs most frequently in the medial area of its base. Morphologically, stress is apt to concentrate on this area. Since its cross-sectional area is small, once broken, there is good possibility it will break after repair.<BR>In the present study, the lower dentures were broken in their median part and repaired, and the effects of the repair on the dynamic characteristics of the denture base were measured in the breaking test and modal analysis.<BR>The results were as follows:<BR>1. The breaking test showed a remarkable drop in the value for the breaking point after repair. Evenwith the use of reinforcing wires, the strength was not restored to what it was before breakage.<BR>2. The modal analysis revealed that the repair of the denture not only by joining the breaking sections with self-curing acrylic resin but also by relining the denture base might be necessary for recovering the dynamic characteristics of denture base before breakage.
