Abstract
Abutment dies which resemble the actual size and shape of crown abutment is essential in most of the research area of fixed prosthodontics like marginal accuracy, crown seating, behavior of luting agent and so on. Seeing the large portion of research is done with round shaped dies in different size and cone angles, the necessity of research on the crown abutment is self-evident. 500 molar abutments were collected randomly through the commercial dental laboratoy, regrdless of their position in the dental arch, sex, and age. The measurements of 22 points of a die were done, and the results were as fogbows : 1. The height of the molar dies was 3.9±1.2mm 2. The bucco-lingual width was 8.9±1.2mm at the base, and 7.4±1.2mm at the occlusal. 3. The desio-sistal width was 8.2±1.2mm at the base, and 7.0±1.3mm at the occlusal.
