A utilização de pistas diretas planas no tratamento precoce da mordida cruzada anterior: relato de caso

Abstract

Anterior crossbite is a change in the buccolingual relationship between the upper and lower incisors, in which all incisors or just one upper incisor occludes on the lingual surface of the lower incisors. When this occlusopathy is diagnosed in primary and mixed dentitions, early intervention can be employed with the use of Planas direct track. If early treatment is not carried out, this change can lead to bone changes, therefore requiring the use of orthodontic and/or orthopedic appliances. The objective of the present study was to report a clinical case of anterior crossbite in a pediatric dentistry patient, in which preventive orthodontics was performed using a Planas direct track in order to avoid future problems in bone development, thus improving occlusion. of the patient. Patient R.P.C.V., male, 6 years old, attended the Pediatric Dentistry Clinic of Universidade Brasil, Campus Fernandópolis-SP for dental treatment. During the initial clinical examination, it was noticed that teeth 52, 51, 61 and 62 were occluding on the lingual surface of the lower incisors; In this way, the diagnosis of anterior crossbite was reached. After evaluating the case, it was decided to carry out a direct Planas trail. For this, direct Flat tracks were made with Composite Resin on teeth 52, 51 and 61. It was possible to notice the uncrossing of the anterior crossbite of the patient in question. The patient is being monitored at the Pediatric Dentistry Clinic at Universidade Brasil. The etiology of crossbite is multifactorial. Early interventions, such as the use of the Planas direct track, can promote harmonious development of the stomatognathic system. The technique used in this case has shown good results. This approach is considered a neuro occlusal rehabilitation, since the action occurs in the neural receptor centers that will result in a response to the stomatognathic system, where occlusal interferences will be identified and removed. The advantages of this technique are: low cost and ease of manufacture. It can be concluded that early treatment with Planas direct track is a minimally invasive approach that can be used to correct and prevent future problems. As observed in this case report, this treatment presents a favorable and rapid result and can even be carried out in children who present behavioral difficulties.
