Strength analysis of root fractures for endodontically treated lateral teeth

Abstract eng:
The paper deals with the strength aspects of catastrophic vertical root fractures, which is the most common reason of tooth loss after the endodontic treatment, what with regards to the American Association of Endodontists is described with the term Cracked Tooth Syndrome. Numerical strength analyses were done for the two basic clinical cases: MOD (mesial-occlusal-distal) reconstruction and total crown overlay. In conclusion, the reconstructions with variant number of post of different material and depth of insertion were chosen to play a protective role in preventing the root and the whole crown against catastrophic fractures.
