Introduction: in recent years a range of functional appliances has been successfully used for Class III. One of them is Klammt Open Elastic Activator, which has a simple design, unlike other devices that are used to correct this type of malocclusion.
Objective: to evaluate the effectiveness of Klammt elastic open activator treatment in Class III Syndrome.
Methods: an analytical, longitudinal and prospective study was carried out at José Martí Orthodontic Service Clinic in Consolación del Sur, Pinar del Río. The target group consisted of 15 patients with Class III syndrome, the sample was comprised of 10 patients who met the inclusion criteria. Clinical diagnosis and cephalometric studies were performed on each patient and after orthodontic treatment.
Results: after treatment, there were positive changes in the overpass, molar relation and incisor protrusion. The most notable cephalometric-skeletal results were: an increase in the ANB angle due to a decrease in the SNB, as well as a decrease in mandibular length. These results were corroborated by applying the Wilcoxon nonparametric test for a significance level of 0.05.
Conclusions: Klammt Open Elastic Activator is an effective method in patients with Class III Syndrome, especially when it is applied in early ages.
