通过初始now测试评价一致性，该测试允许临床医生根据牙槽嵴的尺寸和形状以及软组织的状况选择重衬手术所选的材料。在本研究中，比较并测试了四种自聚合软内衬的一致性，以确定它们是否符合新的国际标准化组织（ISO）10139-1规范。将用海岸A硬度计评估的柔软度与两种热固化有机硅软内衬进行比较，因为后者以其长期稳定的柔软度而闻名。所有四种自聚合软内衬的硬度均符合ISO规范，其圆盘直径范围为41.3至72.2 mm。所有四种软内衬的柔软度均随时间变化，而硅胶的柔软度保持一致。柔软度读数随样品厚度变化显著，表明需要制定测量柔软度特性和确定临床性能所需的最小厚度的标准。
Consistency is evaluated by an initial now test that allows the clinician to select the material of choice for relining procedures according to the size and shape of the ridge and the condition of the soft tissue, In this study, the consistency of four autopolymerized soft liners was compared and tested to determine whether they meet the new International Standards Organization (ISO) 10139-1 specifications. Softness, assessed with a Shore A durometer, was compared with that of two heat-cured silicone soft liners, because the latter are known for their steady softness over long periods of time. The consistencies of all four autopolymerized soft liners complied with ISO specifications and their disk diameter ranged hom 41.3 to 72.2 mm. The softness of all four soft liners changed with time, unlike the silicones whose softness remained consistent. Softness readings varied significantly with sample thickness and indicated the need to develop criteria for measuring softness properties and determining the minimal thickness required for clinical performance.
