Early Correction of Malocclusion Using Planas Direct Tracks

The correction of functional posterior crossbite through Planas Direct Tracks has many characteristics that can become advantages. The aim of this study was to present a clinical case showing how to use this procedure for early correction with resources available through public health services. The patient, a 4-year-old girl, arrived to receive treatment due to a functional unilateral crossbite. When the mandible was moved to the centric position, it was observed that the teeth had occlusal trauma. An occlusal adjustment was performed. The adjustment was not sufficient to promote functional equilibrium; thus, Planas Direct Tracks were made, resulting in functional equilibrium and correction of the malocclusion. As shown in the case report, the Planas Direct Tracks were effective for the correction of the posterior crossbite. If malocclusion is considered a public health problem, implementation of low-cost and easy-to-execute techniques is needed. 1. Introduction Neuroocclusal rehabilitation (NOR) can be defined as a subfield of dentistry that studies the etiology of functional and morphological alterations of the stomatognathic system. Its aim is to investigate and eliminate etiological factors and avert the potential for lesions through selective occlusal griding and/or using Planas Direct Tracks. This innovation can be used at any stage of life to correct a crossbite [1]. The crossbite is one of the most common occlusal alterations. It is an abnormal relationship between the buccal or lingual surfaces of the superior teeth and the inferior teeth when the arches are in centric relation and may be unilateral or bilateral. The most common presentation is unilateral with a functional deviation of the mandibula crossed to the side. It can be classified as a dental crossbite, involving only one or more teeth, muscular or functional, in which case there is a possibility of adapting soft tissues through dental interference, or as a skeletal crossbite, in which alterations in the bone development cause asymmetric growth of the maxillaries [2]. Its etiology is a combination of many factors, including skeletal and neuromuscular components; however, the most frequent cause is palatal reduction [3, 4]. Self-correction is rare, and it is believed that early diagnosis and treatment of a posterior crossbite can help to avoid bone base dystrophies with orthopedic or structural alterations [5]. Several treatments have been applied for correction of these problems, and the studies converge on a common point: the therapy is used for deciduous dentition [6, 7]. The Planas
