Aim of the study: to evaluate the effect of flexible denture base materials on retention of complete denture.
Material & methods: Seven completely edentulous patients with age ranged between 45 and 55 years were selected for this study. Complete conventional heat cured acrylic resin dentures were constructed for all patients .The retention was evaluated after one and three months from dentures delivery. Another set of flexible denture base was constructed for all patients then the retention were evaluated after one and three months from denture delivery.
Results: The result of the study revealed that there were statistically significant differences in the retention between heat and flexible cured acrylic resin denture bases (p value <0.001).
Conclusion: from This study it is concluded that the flexible heat acrylic resin denture base improve retention of complete dentures.
