Form changes of complete dentures were measured in 60 patients. Some of the dentures were made of Paladon 65 and the others of PMMA by the "casting method". The first check was made on the day when the denture was inserted and the last up to 90 days thereafter. In the time the denture was worn, the form changes were recorded and evaluated by means of special markings. It was found that, under masticatory load, the dentures were slightly expanded transversally by 0.2 to 0.4% in the regions of the tuberosity and the anterior teeth. It was not possible to demonstrate a clear difference in the form stability of the base material Paladon 65 and that of PMMA (using the "casting method") during the three month in which the dentures were worn.
对60名患者的全口义齿外形变化进行了测量。部分义齿由Paladon 65制成，其余的通过“铸造法”由聚甲基丙烯酸甲酯制成。首次检查在义齿戴入当天进行，最后一次检查在其后长达90天内进行。在义齿佩戴期间，通过特殊标记记录并评估外形变化。结果发现，在咀嚼负荷下，义齿在结节区和前牙区横向略有扩张，幅度为0.2%至0.4%。在义齿佩戴的三个月期间，未能证明基础材料Paladon 65和聚甲基丙烯酸甲酯（采用“铸造法”）在外形稳定性上存在明显差异。
