Abstract
Statement of Problem: The viscoelastic property is the most important and peculiar charac-teristics of soft liners. But the authorized standard is not certainly established than other den-tal materials.
Purpose of study: This study is aimed to compare the initial flow of gelation of the modified soft liner with 4-META with that of PMMA soft liners using dynamic method and evaluate the clinical acceptance of the trial materials.
Material and Method: This study consists of 3 groups with the given % of 4-META powder in the Coe soft liquid; 0%, 5%, 10%Each group was tested for 10 times to record the change of G’values during 3 hours. the gelation time was recorded by the oscillating rheometer with parallel plate with 1 rad/sec.
Results: As the results of this study, the gelation time of modified soft liner was elongated by 5 to 6 minutes.
Conclusion: The mean gelation time of modified soft liner could be within the range of clin-ically acceptable.
