ABSTRACT
The purpose of this study was to address the therapeutic goals regarding the static and functional occlusion in the completion of orthodontic treatment. For such purpose, a study population comprising 20 female treated Class II malocclusion subjects with an initial mean age of 11 years underwent a two-phase treatment (orthopedics and orthodontics). The patients were diagnosed in centric relation and were treated according to the six keys for normal occlusion and functional occlusal parameters (centric relation, vertical dimension, lateral and anterior guidances, occlusal contacts and direction of forces applied on the teeth). After removal of fixed mechanics, retainers were installed and maintained for two years. Five years after orthodontic completion, the occlusal stability of the patients was evaluated regarding molar relationship and overjet, measured in dental casts. All subjects maintained the normal molar relationship and correct overjet achieved at the end of treatment, indicating a fair level of occlusal stability. The importance of the criteria of the ideal functional occlusion to ensure a better stability after completion orthodontic treatment will be discussed in detail in this paper. In addition, some clinical situations in which localized adjustments are indicated for occlusal refinement will be described.
RESUMO
O objetivo deste estudo foi discorrer sobre as metas terapêuticas referentes à oclusão estática e funcional na finalização de casos ortodônticos. Para tanto, 20 jovens do gênero feminino, com idade média inicial de 11 anos, portadoras de má oclusão de Classe II foram submetidas a tratamento em duas fases (ortopédica e ortodôntica). As pacientes foram diagnosticadas em relação cêntrica e tratadas de acordo com as seis chaves da oclusão normal e os critérios de oclusão funcional (relação cêntrica, dimensão vertical, guias lateral e anterior, contatos oclusais e direção das forças aplicadas aos dentes). Após a remoção dos aparelhos fixos, aparelhos de contenção foram instalados e mantidos durante dois anos. Cinco anos após a finalização ortodôntica, a estabilidade oclusal foi avaliada em modelos de gesso, considerando-se a relação molar e o trespasse horizontal. Todos os pacientes mantiveram a relação molar normal e o trespasse horizontal obtido ao final do tratamento, evidenciando uma boa estabilidade oclusal. A importância dos critérios da oclusão funcional ideal para garantir uma melhor estabilidade pós-ortodontia será descrita detalhadamente neste artigo, visando guiar o profissional durante a fase de finalização ortodôntica. Ainda, serão relatadas situações clínicas em que pequenos ajustes parciais estão indicados para o refinamento oclusal.
