Objective: To determine differences between the degradation of the magnitude of the forces of Orthodontic latex elastics and the time used. Materials and methods: In the in vitro study 60 latex elastics of three types (1/4 4oz, 4/16 6oz y 1/6 4oz) of the GAC brand were used, which were stretched three times its internal diameter and immersed in a moist environment at 37 ° C. The magnitudes of the forces were read after 5, 11 and 23 hours using a dynamometer (Gauge Correx®, 250g, Switzerland). ANOVA test as used to identify statistical significant. Results: There was a statistically significant difference (p <0.001) in the three types of elastic. The degradation of the magnitude of force after 5 hours was 20%, 17% and 15.6%; and 23.4%, 20.7% and 21.7% after 24 hours (1/4 4oz, 6oz 4/16 4oz and sixth, respectively). Conclusion: There are differences between the degradation of the magnitude of the forces of the latex elastics and time of use in the different types of elastics. Keywords: Orthodontics, latex elastic, magnitude of the force degradation.
