Kau CH, Bozic M, English J, Lee R, Bussa H, Ellis RK. Nevertheless, it is considered reliable for surgical and orthodontic planning. Despite potential limitations such as image distortion and superposition, posteroanterior radiograph is useful for other types of assessment. Análise cefalométrica comparativa das alturas faciais, anterior e posterior, em jovens brasileiros, descendentes de xantodermas e leucodermas, com oclusão normal. Takahashi R, Pinzan A, Henriques JFC, Freitas MR, Janson GRP, Almeida RR. 1931 1:45-66.Ĭephalometry focuses on linear and angular dimensions established by bone, teeth and face measurements and cephalometric findings aid diagnosis and help to establish treatment strategies.ĭentists use lateral cephalogram to establish the cephalometric references of normal individuals with a balanced face. A new x-ray technique and its application to orthodontia. Knowledge about craniofacial growth and growth direction, skeletal anatomy, tooth position, tooth relationship with bone structures, and facial profile is essential for accurate treatment planning. CONCLUSÕES:Īs medidas cefalométricas de indivíduos brasileiros com má oclusão Classe I de Angle podem ser usadas para definir a simetria facial e referências de padrão tridimensional, que podem ser úteis para o planejamento ortodôntico e cirúrgico.Īssimetria facial Imagem tridimensional Tomografia computadorizada de feixe cônicoĪssessing skeletal asymmetry by means of cephalometric and panoramic radiograph of individuals in need of orthodontic treatment is an ongoing challenge that requires attention. Os dados foram homogêneos e as diferenças entre os lados direito e esquerdo não foram significativas. O desvio-padrão mínimo, máximo e a média foram descritos em tabelas, e o teste t de Student foi utilizado para definir significância estatística (p < 0,05).

Medições cefalométricas foram realizadas por reconstruções multiplanares (axial, coronal e sagital) usando o VistaDent 3D Pro 2.0 ( Dentsply GAC, Nova Iorque, EUA). Todas as imagens de TCFC foram adquiridas a partir de janeiro de 2009 a dezembro de 2010. Quarenta e sete pacientes (22 meninas e 25 meninos), com idades entre 11 e 16 anos (14 anos, em média), foram atendidos em um serviço de radiologia privado. O objetivo deste estudo é avaliar a simetria dentoesqueléticas em imagens de tomografia computadorizada de feixe cônico (TCFC) de indivíduos brasileiros com má oclusão Classe I de Angle. CONCLUSIONS:Ĭephalometric measurements of Brazilian individuals with Angle Class I malocclusion can be used to establish facial symmetry and three-dimensional standard references which might be useful for orthodontic and surgical planning.įacial asymmetry Three-dimensional imaging Cone-beam computed tomography RESULTS:ĭata were homogeneous, and differences between the right and left sides were not significant. Minimum, maximum, mean and standard deviation values were arranged in tables, and Student t-test was used to determine statistical significance (P < 0.05). Cephalometric measurements were taken by multiplanar reconstruction (axial, coronal and sagittal) using Vista Dent3DPro 2.0 (Dentsply GAC, New York, USA). All CBCT scans were obtained from January, 2009 to December, 2010. MATERIAL:Ī total of 47 patients (22 females and 25 males) aged between 11 and 16 years old (14 years) seen in a private radiology service (CIRO, Goiânia, GO, Brazil) were assessed. The aim of this study is to assess dentoskeletal symmetry in cone-beam computed tomography (CBCT) scans of Brazilian individuals with Angle Class I malocclusion.
