    Estudio comparativo del grado de deformación de elásticos intermaxilares 3/16 fuerza mediana de las marcas Gac, American Orthodontics y Ormco “In Vitro”
    (2013) Barragán Ordoñez, Andrés Eugenio; Cazar Almache, Marcelo Enrique
    The purpose of this study is to compare, determine the degree of deformation of the rubber bands, in our environment, the distributors of commercial houses that distribute intermaxillary elastics not provide a technical and scientific support for their management (1). Studies describe that materials made from latex undergoes changes in its properties, influenced by weather, storage conditions, light, etc., so that there is no information on the degree of deformation of the same, therefore it is necessary to evaluate them in orthodontic mechanics to effect treatment. (2) Finds that the experience forces elastic mouth for daily use factors exist such as saliva and the pH can alter the initial force applied to the spring. Therefore it is important to determine the biomechanical qualities of elastics. In our country the lack of variety of brands, predisposes us to use dubious brands, where the results of our treatments may be affected. A study was conducted in vitro using a machine with eight sensors, to determine the degree of elastic force of each of the marks intermaxilar GAC DENTSPLY, ORMO SYBRON and AMERICAN ORTHODONTICS and at 24 h intervals through 6, 12, 18 and 24 h, applying the method of analysis of variance to determine if there are differences between this marks
