Tensile resistance of complete cast crowns cemented on amalgam foundations retained by amalgapins.
An in vitro study was conducted to examine the influence of the number of remaining cusps and the use of the amalgapin technique on the tensile resistance of complete cast crowns in posterior teeth. Results showed the number of amalgapins and remaining cusps to have no influence on the tensile strength. Failure occurred predominantly at the cemented area (ie, the crown was dislodged from the core).
