The objective of the present investigation was to determine the relationship between time and degradation of the orthodontic tractive force with two types of elastic lacebacks. The investigation design was experimental, in-vitro, longitudinal and prospective. In order to accomplish the objectives of the investigation, a total of 20 lacebacks composed of metallic ligature No. 09 (RMO) and elastomeric modules, 10 carried elastomeric ligatures and 10 spacer elastomers (GAC and Dentaurum, respectively) were studied, the lacebacks were activated until they had a force of 200 grams. Strength levels were measured with a gramometer (Correx 250g) after 4 hours, 1, 2 and 3 weeks. Data were analyzed using the repeated measures ANOVA. We found 32.13 ± 10.77% degradation of the initial strength of the samples within the first 4 hours and 21.41 ± 7.2% of force degradation occurred in the first week; 13.23 ± 7.36% in the second week and 20.37 ± 7.18% strength degradation occurred up to the third week. We concluded that there is a significant relationship between time and degradation of orthodontic tractive force with two types of elastic lacebacks
