This is an experimental in vitro research, meaning that the research was conducted in a laboratory controlled environment, actively manipulating the variables and observing the results. For the results, the dimensional alteration of the silicones by addition at time intervals was considered in order to observe how the silicone develops in the polymerization process. The ANOVA analysis detected significant dimensional differences between the different types of silicones, in a short period of 24 hours and a distant period of 15 days, while in a medium period of 8 days no significant dimensional differences were found between them; Furthermore, it was determined that the silicone President Coltene presents varying dimensional changes throughout the study period. This behavior is similar to that of Ivoclar Virtual, although it presented less variability. Finally, Kerr Extrude is the silicone that presented the least changes over time with respect to the aforementioned silicones, denoting a consolidation towards contraction processes with respect to time, which differs notably from the other silicones analyzed. |
