Abstract
In dental technology, in order to match root posts to curved root canals, the fixation part consists of a material with mechanical properties, such as ductility and flexural rigidity, that permit topical matching of the fixation part to the curved root canal. For example, the ductility increases from the oral side of the fixation part to the root apex.
