Abstract
Photoelastic models of pin-amalgam restorations were constructed to simulate different pin-dentinamalgam relationships. The stress-raising effect of a pin is influenced by the axial stiffness of the pin and its capability of bonding with the amalgam. The stress produced by a very stiff non-bonded pin could cause failure of the restoration.This publication has 5 references indexed in Scilit:
