“…5 The clinical features of these growth patterns are well described in the literature and often manifest as either a skeletal open or deep bite. [6][7][8][9] It has been suggested that head form is closely associated with both vertical and transverse growth patterns. 10,11 Dolichocephalic head forms have been described as having a narrow face and hyperdivergent mandible, while brachycephalic skulls exhibit a broader face and hypodivergent mandible.…”

Objective: To evaluate the relationship between mandibular divergence and vertical and transverse dimensions of the face. Materials and Methods: A sample was recruited from the orthodontic clinic of the University of Otago, New Zealand. The recruited participants (N 5 60) were assigned to three different groups based on the mandibular plane angle (hyperdivergent, n 5 20; normodivergent, n 5 20; and hypodivergent, n 5 20). The sample consisted of 31 females and 29 males, with a mean age of 21.1 years (SD 6 5.0). Facial scans were recorded for each participant using a three-dimensional (3D) white-light scanner and then merged to form a single 3D image of the face. Vertical and transverse measurements of the face were assessed from the 3D facial image.

“…The choice of treatment protocol depends on many factors, including esthetic and occlusal aspects, morphologic characteristics, and the severity of the skeletal anomaly. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] The indication for molar intrusion is often based on the assumption that the value of molar height in open bite patients is greater than in the ''normal population.'' 2,6,10,[27][28][29] Many authors state that increased molar height is one of the common features of individuals with dentoskeletal open bite, and they advocate molar intrusion to correct the disharmony.…”

Objective: To evaluate the skeletal and dentoalveolar components in adult subjects with skeletal open bite in the presence or absence of dental compensation. Materials and Methods: The study sample included 69 adult female subjects who belonged to three groups according to skeletal vertical relationships and overbite. A total of 15 variables (5 angular, 10 linear) were evaluated. Values in the dentally compensated open bite group (COBG), the dentally noncompensated open bite group (NCOBG), and the control group with normal vertical skeletal relationships and overbite (CG) were compared by means of parametric statistics. Results: The COBG and the NCOBG showed significantly greater incisor and molar heights in both jaws than the CG. No significant difference in upper or lower molar height was found between COBG and NCOBG. Incisor height was significantly greater in COBG than in NCOBG. Elongation in the incisor region was accompanied by significant narrowing of the lower anterior alveolar process in both skeletal open bite groups. Proclination of the upper incisors was significantly smaller in the COBG than in the other groups. Conclusions: Dentoalveolar components consisting of incisor elongation and inclination play a significant role in compensating for skeletal open bite configuration in adult subjects. Increased molar height is a common finding in adults with skeletal open bite. (Angle Orthod. 2011;81:564-569.)

“…A média encontrada (-0,15±1,68º) indicou um pequeno desvio-padrão, se comparado ao de outros trabalhos envolvendo amostras de indivíduos com oclusão normal, como Cangialosi 5 , que encontrou uma média de 7,1±3,7º para o ângulo PP.S-N.…”

ResumoIntrodução: o posicionamento da maxila no esqueleto craniofacial tem sido motivo de investigação por diversos autores. Traduzindo suas idéias por meio de medidas lineares ou angulares, tais autores definiram o que consideraram como a posição "ideal", "normal" e, ainda, "aceitável" ou "inaceitável" da maxila, relacionando-a, na maioria das vezes, com a base do crânio. A partir da avaliação de indivíduos com oclusão considerada normal e com bom equilíbrio facial, eram calculados valores médios e desvios-padrão de determinadas medidas, os quais eram tomados como parâmetros para avaliações cefalométricas de pacientes distintos. Objetivos: diante das divergências de opiniões encontradas na literatura, a proposta do presente estudo foi avaliar o posicionamento da maxila nos sentidos vertical e ântero-posterior, além da sua inclinação, numa amostra de 94 indivíduos com oclusão normal e equilíbrio facial. Métodos: foram determinadas correlações entre medidas do próprio indivíduo: OPI-N com OPI-ENA e N-ENA com ENA-ENP. Conclusões: a partir dos fortes índices de correlação encontrados, concluiu-se que a medida OPI-N pode ser tomada como referência para determinação de OPI-ENA, da mesma forma que ENA-ENP pode ser considerada para determinação de N-ENA, definindo, respectivamente, a posição da maxila nos sentidos sagital e vertical. A inclinação da maxila, representada aqui pelo ângulo OPI.ENA.ENP, teve valor médio estatisticamente próximo a 0º (zero grau), indicando forte tendência do prolongamento posterior do plano palatino (ENA-ENP) tangenciar a base posterior do crânio (ponto OPI), o que se revela como uma importante característica de indivíduos com oclusão normal e equilíbrio facial.Palavras-chave: Individualização.
