dc.descriptionObjective: To evaluate the effectiveness and dimensional stability of three impression materials for complete dentures: Addition Silicones, Irreversible Hydrocolloid and Polyether. Methodology: A total of 180 samples, which were divided into 3 groups, each group consisted of 60 impressions with addition silicone, polyether and alginate, respectively, were obtained. Of the 60 impressions with each material, 20 were poured at 24 hours after taking the impression, 20 at 48 and 20 at 72 hours after recollection. 30 different impressions were stored by the manufacturer’s storage instructions and 30 on outdoors conditions in the same room and temperature. Each impression was poured at the times indicated above using Type IV gypsum. Results: To compare the three impression materials we used ANOVA test. We obtained that with addition Silicone, at 24 hours statistically differs of the value obtained at 48 hours and 72 hours following the manufacturer’s instructions for storage. Alginate did not present statistically difference at 24, 48 and 72 hours, following the manufacturer instructions of storage. When the polyether is stored on outdoors conditions, no significant differences were found in any of the three times studied, 24, 48 and 72 hours. Conclusions: 1. the material that showed higher dimensional stability over time is Polyether, followed by addition silicone and then alginate. 2. The storage according to the manufacturer instructions only influences the alginate. 3. Polyether is a material of great qualities, that’s the reason why is used on the implantology area and has been a material that has been replaced by silicones over time, leaving aside their outstanding features.en
