Determinación de los cambios transversales en el maxilar, posterior al tratamiento con pistas planas directas Vs. Quad Helix. Prueba piloto

Abstract

Some malocclusions such as the posterior crossbite may have a negative impact on the stomatognathic system leading to skeletal, dental, functional alterations and even the progress of facial asymmetries. Early intervention can prevent progress in to adolescent age, where the treatment of such malocclusion can be complex. The Direct Flat Tracks (PPD) and the Quad Hélix (QH) are therapeutic interventions referenced in the scientific literature and frequently used in early stages of the dentition that promote functional stimuli for the successful correction of the posterior crossbite. To determine the transversal changes in the maxilla, after the treatment with Direct Flat Tracks (PPD) vs Quad-Hélix (QH) in children from 6 to 9 years with posterior crossbite. A pilot study where transversal changes in upper maxilla were evaluated after cementation of Direct Flat Tracks (PPD) and Quad Hélix (QH) to six children of public schools in Vereda Río Frio, Zipaquirá, during 6 months. When comparing T1 and T2 of both different treatments, the one performed with Quad Helix (QH) showed a greater increase (average of 0.3 mm) in the two distances (intercanine and intermolar), however these data were not statistically significant. The therapeutic intervention in children aged 6 to 9 years with posterior cross bite performed in children of Zipaquirá’s rural zone, showed greater changes in the intercanine and intermolar distance after 6 months of treatment applying Quad Hélix therapy (QD), however, these results are not statistically significant due to the small sample size and the short follow-up period.
