Introduction: During children’s growth and development, disharmonies may occur at the level of facial-skull. Among these is Class II Division 1 Syndrome, being mandibular progress one of the alternatives for its correction. With this aim, Dr. Bimler designed a device that allows a better adaptation of the patient. Objective: Describe the skeletal cephalometric changes that occur with the use of the Elastic Modeling, in the treatment of Class II Division 1 Syndrome. Materials and Methods: An observational, descriptive and retrospective study were carried out, the work universe was made from 33 clinical records, all of them belong to patient with this anaraxia, treated with Bimler appliance Type A. Results: The total profile angle diminished its initial average from 14.6 to 11.8 mm., the maxillary depth increased in 3,2mm; the Jaw Diagonal and the Suborbital Facial Height increased too in 11.1mm and 4, 3 mm respectively, whereas the skeletal ledge decreased in 1.6 mm. 80% of the males and 72.3% of the females had transformed their profile to straight. Conclusions: With the use of Elastic Modeler Type A in the treatment of Class II Division 1 Syndrome, cephalometric variables show favorable changes towards the correction of skeletal disharmonies, resulting in a significant reduction of the skeletal ledge, which contributes to the more orthognathic profile of patients.
