Fracturing molars with axial forces.

Extracted human molars were prepared with different sized occlusal cavities and restored with a high-copper amalgam. Loads were applied along the long axis of the teeth, and forces required to fracture the teeth were recorded. More force was required to break samples with the larger restorations than was required to break samples with the smaller restorations.

Fracture resistance of mandibular molars with occlusal class I amalgam preparations.

The finding that large occlusal Class I restorations weaken premolars is not confirmed for natural mandibular molars because no statistically significant difference was found in the mean loads needed to fracture mandibular molars that were unprepared, minimally prepared, or prepared with a large occlusal amalgam restorations. Similarly, there was no statistically significant change in the amount of force necessary to fracture natural mandibular molars prepared with sharp vs round internal line angles (a no. 56 vs a no. 330 bur). Duplication of the experiment in acrylic resin mandibular molars confirmed the results of a previous experiment by Re and Norling as well as the results relating to sharp vs round internal line angles found in this experiment on natural mandibular molars. Acrylic resin teeth of homogeneous shape and substance overcome some of the sampling problems inherent in obtaining suitable human teeth for testing purposes; however, further testing of this material is indicated.
