Neuroclusal rehabilitation and planas direct tracks in the posterior crossbite treatment

ABSTRACT Objective: To evaluate the effectiveness of neuroclusal rehabilitation treatment using Planas Direct for posterior crossbite correction. Methods: This is a clinical study in which 43 children were selected, of both sexes, between 3 and 6 years old, diagnosed with posterior crossbite and midline deviation. Interviews were conducted with the parents in order to ascertain the practice of harmful habits. The treatment was based on neuroclusal rehabilitation in order to investigate and eliminate the occlusal obstacles which depreciate the stomatognathic system. The aim of the study was also to reprogram the affected neuromuscular activity. Planas direct were performed on crossed teeth in order to restructure the neuroclusal area and the stomatognathic system, as well. Epi Info software, 3.5.4 for Windows, through the distribution of frequencies and the Pearson chi-square test were used for statistical analysis. Results: Occlusal restoration in 79% of children was performed however 21% abandoned treatment. The crossbite and midline correction period ranged from from 14° to the 91° treatment. Significant associations of the variables were observed as follows: deleterious habits (p = 0.0001) and midline deviation (p = 0.0001) at the beginning or end of treatment. Conclusion: It was concluded that the neuroclusal rehabilitation and Direct Slopes Planas were effective in correcting the posterior crossbite.
