[The loading capacity of different pin-post structural systems].

Abstract

Compared with semi-individual or individual cast constructions, fully manufactured post-abutment systems are exposed to stronger torsional loads due to their circular cross-sections. The investigations refer to the question, to what extent different manufactured constructions in the root of a tooth will withstand torsional moments. A cold-pressured connection between titanium-post and titanium-construction was tested as to its mechanical load capacity. Moreover, the mechanical compound stability of individual cast constructions on friction-posts was investigated.
