ABSTRACT
Introduction and objectiveUnderstanding the anatomical and physiological modulation of the occlusal plane during growth is criticalin identifying some of the factors contributing to the establishment of malocclusion.To characterize the occlusal plane and the development of different dentoskeletal types in school childrenbetween 5 and 6 years.Materials and MethodsThis descriptive study considered a convenience sample of 107 schoolchildren who met the inclusioncriteria. The analyzed variables were Dental Framework, Kim, occlusal plane and FH plane, determined byusing anatomic and orbital positions, which served as reference points. Occlusal planes were determinedby considering deciduous and mixed dentition, respectively.ResultsThe classification of the occlusal plane identified in showed that in 65,7% of the school children there wasa stable occlusal plane, in 22,9% inclined and in 11,4% flat. In Class III, no data were found with respectto the inclined plane. All patients were between a stable and a flat occlusal plane. A greater proportionwas that of the angle of the acute maxillary plane. In the multivariate analysis identified a possible (11,5%) was found consistent of males with a Class II skeletal pattern, no occlusal plane angulation and obtuseangulation of the maxillary plane.ConclusionThere is a tendency for Class I children to have a stable occlusal plane, Class II individuals an inclinedocclusal plane, and Class III children a flat occlusal plane.
