Introduction. They have been carried out in order to evaluate dimensional stability, a study groupmakes its own abut-ment in order to determine if there is no dimensional variation of the different impressionmaterials used in oral rehabi-litation. This variation will depend on different factors such as time, material, temperature, humidity among others. Objective. In this sense, the objective of the study was to evaluate the dimensional stabili-ty of the addition silicone/polyvinylsiloxane (VPS) and for this, time will be taken into account. Methods. We went on to an experimental study. The sample consisted of a total of 50 models, 25 for VPS and 25 for the control group whose material was silicone by condensation. To carry out the study, a master model was made taking into account 6 locations and 5 time periods where the first group at 0 minutes, the second group at 20 minutes, the third group at 1 hour, the fourth group at 6 hours and the fifth group at 24 hours, after the impression was taken. Results. After taking the impression when it is counted at 0 minutes, at 60 minutes, at 6 hours and at 24 hours, the statistic t ≥ 2.1318 and p≤ 0.05 is obtained, confirming that there are significant differences between the two silicones with respect to the dimensional variation. Conclusions. It is concluded that there is a variation in dimensional stability when compared with the control group such as silicone by condensation..
