Abstract
The effect of thermocycling and surface finishing on the marginal fidelity of copings for a metal ceramic crown was examined. Methods for minimizing the loss of marginal fidelity were evaluated. The results were as follows ; 1. Thermocycling of ceramic metal coping resulted in increased marginal gap. 2. The greatest marginal gap occurred during the first thermocycling of the copings. 3. No additional distortion of marginal fidelity occurred when surface finishing and second thermocycling were completed after initial thermocycling. 4. The gab increases according to various treatment methods showed group 1 to be the highest values. 5. There was no significant difference between group 2 and group 3(p>0.05). 6. There was significant difference between group 1 and group 2, 3(p<0.05). 7. There was no significant difference among the measurement sites.
