Abstract

Purpose: Of this study is to examine the effect of storage times and temperature degrees of cleansing solutions on retention of overdenture bar attachments. Materials and Methods: 120 hader bar clips were divided into two groups according to type of cleansing solution (Tape water and Corega), each group incubated in (20°C, 37°C and 60°C) for 1/2 hour and 1 hour. Specimen consists of two blocks (A and B), Block A contained implants and the bar (matrix), block B contained of yellow hader clip (patrix). Retention force was measured using universal testing machine results was compared by T student-test and Analysis of Variance (ANOVA) and followed by Tukey’s HSD test when P value ≤ 0.05 considered significant and surface changes of test clips were examined using Scanning Electron Microscopy (SEM). Results: Immersion in water and Corega at 60°C for 1/2 hour and 1 hour per day for 6 months simulation significantly increase the retention of bar attachment p ≤ 0.05 but at 20°C for 1/2 hour and 1 hour significantly decrease the retention of bar attachment p ≤ 0.05. SEM revealed increased roughness in plastic clips after immersion in all groups. Conclusion: Denture cleansing solutions (Corega and water) at 60°C increase the retention value of bar attachments. Different storage times of Corega and water have no effect on the retention of bar overdenture attachments.
