ALVAREZ MORA, Ivette et al. Results of type II division 1 malocclusion treatment, with Klammt elastic open activator. Medisur [online]. 2017, vol.15, n.3, pp. 318-326. ISSN 1727-897X.
Foundation: Klammt elastic open activator has been used in Cuba in the last years. It is a fuctional aparathus whis is found among the treatment options for type II division 1 maloclussion. Objective: To describe Klammt elastic open activator for correcting type II division 1 maloclussion with Klammt elastic open activator.Methods: A quasi-experimental intervention was carried out, including 20 children from the Antonio Maceo elementary school, from the Cienfuegos municipality Health Area II. For the diagnosis skull lateral cephalograms were taken at the beginning and at a year time from treatment beginning, to which linear and/or angular measurements of Steiner, Ricketts and McNamara were applied. Changes in measurements of skull lateral radiographs were observed, with cephalometric variations of craniofacial of important statistical significance; the same occurred in soft tissues, which generally denoted an improvement of the profile, especially of the nasolabial angle, essentially originating in its labial component. Skeletal and soft tissue cephalometric changes were evaluated before and after treatment.Results: Changes in measurements of skull lateral radiographs were observed, with cephalometric variations of craniofacial of important statistical significance; The same occurred in soft tissues, which generally denoted a profile improvement, especially of the nasolabial angle, essentially originating in its labial component.Conclusion: The effectiveness of Klammt elastic open activator in the treatment of class II malocclusions division 1 was verified, as it was corrected in patients of early age, which was evidenced in the resulting variations in the facial biotype towards more favorable patterns.
