| Sumario: | Objective: To determine the prevalence of skeletal open bite (SOB) from clinical records of dolicofacial patients, of both sexes, whose received orthodontic treatment. Methods: Fifty-four clinical histories of patients with dolicofacil biotype of both sexes, between 18 and 35 years of age, were analyzed. On lateral cranial radiographs, analyzes were made in the vertical and sagittal planes according to the cephalometric norms of Björk Jarabak and Ricketts. The data were expressed as the mean ± SD and the comparisons between sexes were performed using the Student's t-test. Statistical significance was established with p<0.05. Results: Twenty-one dolicofacial patients (38.89%) presented malocclusion of SOB. The mandibular arch was slightly increased in women patients (2º above the norm), with a significant difference (p<0.01) with respect to the male sex that was diminished (4º below the norm). The posterior facial height of both sexes showed lower values with respect to the norm, characteristic of dolicofacial patterns with short mandibular branch and posterior rotational growth; the value was significantly lower in the mens than in the women (p <0.05). The overbite showed lower mean values compared to the norm; a decrease of 5.2 mm was observed in women and 3.68 mm in mens. Overbite was significantly lower in women than in mens (p<0.02). Conclusions: In our country, the dolicofacial pattern of individuals is the less frequent in daily practice and when encountering a patient with these growth characteristics, we must suspect a malocclusion of SOB. This may be present at the time of the examination or manifest in the future, so it must be taken the necessary precautions to obtain an accurate diagnosis and to perform a correct treatment. |
