Avaliação da inclinação do incisivo inferior através da tomografia computadorizada

Abstract: INTRODUÇÃO: durante muito tempo, a Ortodontia baseou-se em valores normativos obtidos através das análises cefalométricas existentes, utilizando a telerradiografia em norma lateral como exame principal no diagnóstico ortodôntico, ditando o plano de tratamento. O incisivo inferior, em particular, recebeu normas cefalométricas propostas por diversos autores, dentre eles Tweed. Entretanto, os exames radiográficos possuem limitações, pois, em uma imagem bidimensional de uma estrutura tridimensional, a superposição… Show more

“…In a few studies, the buccal alveolar cortical plate is unperceivable by CT scans, leading the examiner to believe that the examined region has no supporting periodontal structure. 2 , 4 , 5 However, the latter exists, although it does not reveal as a precise, topographically perceptible image 12 that could be seen by microscopic slices.…”

“…It is known that lateral cephalograms do not identify the incisor of which analysis was based on an unspecific and combined image of all teeth in the anterior region. 8 Several studies have been conducted to analyze the quality of images obtained by CBCT examinations. Menezes et al 16 assessed different examinations with voxel sizes of 0.2, 0.3, and 0.4 mm, and concluded that the morphology of dental and bone structures was relatively accurate on CBCT scans.…”

“…The images obtained by this new method demonstrate that the condition of teeth, especially maxillary and mandibular incisors located at the anterior region where there is greater compensation, is more fragile than what was previously believed. 8 , 9 In other words, the relationship between dental root and alveolar bone is critical.…”

“…Ao longo dos séculos a evolução do estudo craniométrico foi ganhando mais destaque na literatura, o que fez com que os avanços da tecnologia incentivassem desenvolver aparelhos para aperfeiçoar as mensurações do crânio. Combinando com o advento do aparelho do raios x e do cefalostato criado por Broadbent e Hofrath em 1931, foi possível padronizar a radiografia em normal lateral e introduzir seu uso na Ortodontia, aumentando precisão dos dados craniométricos, tecidos moles, relação maxilomandibular e posição dos dentes em suas bases ósseas, que contribuirão como um guia no tratamento ortodôntico, melhorando assim, o diagnóstico e o plano de tratamento 1981;CAPELOZZA FILHO et al, 2008).…”
