Adequate retention is a basic requirement for the acceptance of complete denture. The aim of this study was to evaluate the retention quality of fluid denture base materials and compare it with conventional acrylic denture base materials Method: Sixteen edentulous male patients with an age 45-60 years participated in the study. For each patient two denture bases were constructed, one of them made from fluid denture base materials and the other made from hot acrylic denture base materials. A specially designed strain gauge measuring device was used to measure the force required to dislodge the two dentures from basal seats. Six measurements of retention of newly inserted denture base were recorded for each patient (three for maxillary acrylic denture base and three for maxillary fluid denture base). Results: The results of the retention test showed that the fluid denture base materials required more force in order to dislodge denture than the heat cure denture base materials, which means a significant improvement in retention quality obtained by fluid denture base materials. Conclusions: It has appeared that the fluid acrylic denture base materials produce denture base material with excellent retentive efficiency to the underlying tissue when compared to conventional denture base materials.

Objective: To evaluate the effect of thermocycling on the color stability of heat and self-cure resins after immersion in denture cleansers. Material and methods: Forty-eight disks of heat and self-cure resins were fabricated. The specimens of each material were divided into 4 subgroups (n = 12) and immersed in different denture cleansers (Distilled water {control}, Corega, StainAway Plus and Polident) daily for 1 week and first color measurements (T1) were recorded (before thermocycing). The specimens were then subjected to 5000 cycles of thermocycling and the second color measurements (T2) were recorded (after thermocycling). Results: A significant increase of color change was noticed in self-cure compared to heat-cure resins after thermocycling (p=0.001). The color change in heat-cure resins immersed in different solutions was insignificant (p>0.05). Whereas, there was significant color changes in self-cure resins among denture cleansers (p<0.05). The mean difference of color change was greater in self-cure resins immersed in Corega (3.93 ± 2.71) and Polident (3.55 ± 2.06) compared to the control group (0.15 ± 1.66) and lower in specimens immersed in Stain Away Plus (1.36 ± 1.60) compared to Corega. There was a significant decrease in the mean of color change after thermocycling in heat-cure resins immersed in distelled water and Stain Away Plus (p<0.05) and in self-cure resins immersed in Corega, Stain Away Plus and Polident compared to color change before thermocycling (p<0.05). Conclusion: Aging process resulted in a significant color change in self-cure compared to heat-cure resins and the value of color difference was varied according to the denture cleanser used.
