This last one has a favorable prognosis when the treatment occurs in early stages. Considering this, Planas direct tracks have been showing to be an effective and less invasive alternative when few dental elements are involved. This paper presents a clinical case of a 6-year-old patient with functional unilateral anterior crossbite whose differentiated diagnosis and early intervention allowed a successful treatment. By manipulating the jaw and positioning the condyles in centric relation (CR), the presence of occlusal interference between the upper and lower deciduous canines on the right side was noticed, which are the causes of mandible anterior displacement with occlusion in MIH. For correction, Planas direct track therapy was used on the upper right canine with composite resin followed by slight wear on the lower right canine. The premature contacts were eliminated, creating an inclined plane of approximately 45 degrees on the palatal face of the upper canine and a slight occlusal adjustment on the incisal surface of the lower right canine. The use of this technique allowed the correction of the functional anterior crossbite immediately after the removal of the occlusal interference. This case shows that the early treatment of crossbites increases the chances of a successful rehabilitation of stomatognathic system. The use of Planas direct tracks proved to be an effective, low-cost, and easy to implement alternative for functional crossbites correction.
