ABSTRACT

INTRODUCTION: Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention of tooth #53, tendency to vertical growth of the face and facial asymmetry. The discrepancy on the upper arch was -2.0 mm and -5.0 mm on the lower arch. METHODS: The presurgical orthodontic treatment was performed with extraction of the teeth #35 and #45. On the upper arch, teeth #53, #12 and supernumerary were extracted to accomplish the traction of the impacted canine. The spaces of the lower extractions were closed with mesialization of posterior segment. After aligning and leveling the teeth, extractions spaces closure and correct positioning of teeth on the bone bases, the correct intercuspation of the dental arch, with molars and canines in Angle's Class I, coincident midline, normal overjet and overbite and ideal torques, were evaluated through study models. The patient was submitted to orthognathic surgery and then the postsurgical orthodontic treatment was finished. RESULTS: The Class III malocclusion was treated establishing occlusal and facial normal standards.

ABSTRACT

INTRODUCTION: Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention of tooth #53, tendency to vertical growth of the face and facial asymmetry. The discrepancy on the upper arch was -2.0 mm and -5.0 mm on the lower arch. METHODS: The pre-surgical orthodontic treatment was performed with extractions of the teeth #35 and #45. On the upper arch, teeth #53, #12 and supernumerary were extracted to accomplish the traction of the impacted canine. The spaces of the lower extractions were closed with mesialization of posterior segment. After aligning and leveling the teeth, extractions spaces closure and correct positioning of teeth on the bone bases, the correct intercuspation of the dental arch, with molars and canines in Angle's Class I, coincident midline, normal overjet and overbite and ideal torques, were evaluated through study models. The patient was submitted to orthognathic surgery and then the post-surgical orthodontic treatment was finished. RESULTS: The Class III malocclusion was treated establishing occlusal and facial normal standards.


INTRODUÇÃO: o presente trabalho apresenta um tratamento ortodôntico-cirúrgico realizado em paciente portadora de má oclusão de Classe III esquelética com crescimento mandibular, protrusão dentária superior e inferior, trespasse horizontal de -3,0mm, trespasse vertical de -1,0mm, ausência congênita do dente 22, dentes 13 e supranumerários inclusos, dente 12 com forma conoide e parcialmente irrompido em supraversão, retenção prolongada do dente 53, tendência ao crescimento vertical da face e assimetria facial. A discrepância na arcada superior era de -2,0mm, e na inferior era de -5,0mm. MÉTODOS: o tratamento ortodôntico pré-cirúrgico foi realizado com extrações dos dentes 35 e 45. Na arcada superior foram extraídos os dentes 53, 12 e supranumerário, para efetuar o tracionamento do canino incluso. Os espaços das extrações inferiores foram fechados com mesialização do segmento posterior. Após o alinhamento e nivelamento dos dentes, foram avaliados por meio de modelos de estudo o fechamento dos espaços das extrações e o posicionamento correto dos dentes nas bases ósseas, a intercuspidação correta das arcadas dentárias, com molares e caninos em Classe I de Angle, linhas medianas coincidentes, trespasse horizontal e trespasse vertical normais e torques ideais. A paciente foi encaminhada para realização de cirurgia ortognática e, em seguida, o tratamento ortodôntico pós-cirúrgico foi finalizado. RESULTADOS: a má oclusão de Classe III foi corrigida, estabelecendo padrões oclusais e faciais normais.

ABSTRACT

A exodontia de um incisivo inferior pode ser considerada uma opção valiosa na busca de excelência nos resultados ortodônticos para obtenção de máxima função, estética e estabilidade. O objetivo deste estudo foi reunir informações referentes às indicações, contraindicações, vantagens, desvantagens e estabilidade dos resultados obtidos nos tratamentos realizados com extração de um incisivo inferior. Essa opção de tratamento pode ser indicada em más oclusões com discrepância de volume dentário anterior devido a incisivos superiores estreitos e/ou incisivos inferiores largos. É contraindicada em más oclusões sem discrepância anterior ou com discrepâncias ocasionadas por incisivos superiores largos e/ou incisivos inferiores estreitos. A literatura sugere maior estabilidade pós-tratamento quando comparada com a opção de extrações de pré-molares. Além do diagnóstico cuidadoso, obtido com a colaboração do set-up, a habilidade e a experiência clínica do profissional são importantes para o sucesso dos resultados ortodônticos alcançados com essa opção de tratamento.


Lower incisor extraction can be regarded as a valuable option in the pursuit of excellence in orthodontic results in terms of function, aesthetics and stability. The aim of this study was to gather information about the indications, contraindications, advantages, disadvantages and stability of the results achieved in treatments performed with lower incisor extraction. This treatment option may be indicated in malocclusions with anterior dental volume discrepancy due to narrow maxillary incisors and/or large mandibular incisors. It is contraindicated in malocclusions without anterior discrepancy or with discrepancies caused by large maxillary incisors and/or narrow mandibular incisors. The literature suggests this method affords improved posttreatment stability compared with premolar extraction. As well as a careful diagnosis, established with the aid of a diagnostic setup, professional skills and clinical experience are instrumental in achieving successful orthodontic results with this treatment option.

ABSTRACT

O presente artigo ilustra um tratamento ortodôntico sem extrações para correção de uma má oclusão de Classe II com apinhamento. As características dessa má oclusão incluíam incisivos superiores protruídos, incisivos inferiores retruídos, sobressaliência de 7mm, sobremordida profunda e tendência de crescimento vertical. O tratamento ortodôntico, sem extrações dentárias consistiu de expansão ortopédica da maxila com expansor tipo Haas, placa labioativa associada à mecânica de classe III, para inclinação distal dos molares inferiores, e aparelho extrabucal de tração combinada, para distalização dos molares superiores.
