ABSTRACT
In light of the results of this study, a number of conclusions can be made with reference to full coverage castings. 1. Dental cement causes occlusal displacement. Zinc phosphate cement results in a greater displacement than does temporary zinc oxide-eugenol cement. 2. The disparity in seating of cast restorations obtained with no cement, temporary zinc oxide-eugenol cement, and zinc phosphate cement tends to reduce in magnitude with increasing taper of the tooth preparations. 3. Venting of crowns is an effective way of reducing the disparity in seating between no cement, temporary zinc oxide-eugenol cement, and zinc phosphate cement. 4. Remount records should be made with the restorations cemented with temporary zinc oxide-eugenol cement rather than held to the teeth by friction alone.
