Comparison study of elastic impression material.
The study of four elastic impression materials indicated that master castings could be more accurately seated on casts made from MOD impressions than from full crown impressions. A discrepancy between clinical acceptance and statistical identity was also demonstrated. The study indicated that by altering just one variable, the pour time, a wide range of results is obtained, some clinically acceptable and others clinically unacceptable.
