Temporary soft lining materials (TSLM) can not be used for a long time. However, removing this material from denture base with burs causes an unhygienic environment and requires much labor. Therefore, it is necessary to prime the separator for improving separability (ease of separate) between TSLM and denture base.<BR>The purpose of this paper was to examine the effect of the passage of time after attaching TSLM, SOFT-LINER, COE-SOFT, and Visco-gel to the denture base ACRON, ACRON MC, and Palapress on separability. To simulate the chewing cycles, a loading apparatus, which enables loading repeatedly adequate masticatory force, was designed. The separability was evaluated from tensile strength and the ratio between interface failure and cohesive failure after testing.<BR>Furthermore, Visco-gel was tested after warming specimen's attached TSLM (70°C, 5 min) or cooling (5°C, 1 min).<BR>The conclusions were as follows:<BR>1. The tensile strengths of all specimens without separator were gradually increased by the passage of time. However, there were no significant difference of tensile strength with separator for days 1, 3, and 7.<BR>2. Although most of the separating surfaces of specimens without a separator showed cohesive failure, specimens with a separatorrevealed interface failure, and specimens with Vaseline showed mixed failure.<BR>3. The tensile strengths of the TSLM to ACRON, and ACRON MC was greater than that for Palapress.<BR>4. In case of Visco-gel, greater separability was obtained when specimens were warmed or cooled before testing.
