Abstract
|
|
|
The purpose of this study was to evaluate the fracture resistance of tooth restore with gold inlay. A profound understanding of the isthmus width factor, which is one of the several parameters of cavity designs, would facilitate the appropriate
cavity
preparation in a specific clinical situation.
@ES The results were as follows:
@EN 1. All of the experimental models which were filled with gold inlay revealed similar direction of displacement to that of the natural tooth model under the same load type. But in the models with empty cavities, as the isthmus width increased,
the
degree of displacement increased in the case of divided load type.
