title: Comparison study of elastic impression material.
abstract: 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.
