Abstract
An experiment was conducted to investigate the effect of internal escape channels and perimetric occlusal bevel on the completeness of seating of full veneer cast-gold crown during cementation. Twenty-four crowns were fabricated on Ivorine dies and cemented by standardized procedures. Two experimental groups were reused to study the effect of the addition of a perimetric occlusal bevel. The vertical dimension was significantly reduced in all four test groups when compared with the control. We concluded that an internal escape channel improves the complete seating of a full veneer cast-gold crown.
