In vitro evaluation of the fracture strength of all-ceramic core materials on zirconium posts

OBJECTIVE For most endodontically treated teeth, tooth-colored post-core systems are preferable for esthetic reasons. Therefore, improvements in material strength must also consider tooth colored post-core complexes. The objective of this study was to evaluate the difference in tooth colored post-core complex strengths. MATERIALS AND METHODS A total of 33 human maxillary central incisor teeth...

Fracture Problems in Composite Materials

In this paper a series of fracture problems in composite materials are identified, their methods of solution are briefly discussed, and some sample results are presented. The main problem of interest is the determination of the stress state in the neighborhood of localized imperfections such as cracks and inclusions which may exist in the composite. Particular emphasis is placed on the evaluati...
