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.
对四种弹性印模材料的研究表明，与全冠印模相比，在由MOD印模制作的模型上，主铸型能更准确地就位。还证明了临床可接受性与统计学一致性之间存在差异。该研究表明，仅改变一个变量即灌注时间，就能获得广泛的结果，有些在临床上可接受，而有些则不可接受。
