sistema estomatognático O tratamento reabilitador é complexo não somente por envolver etapas clínicas e laboratoriais que precisam de planejamento e execução criteriosos, mas por estabelecer íntimas relações com o complexo sistema estomatognático, interferindo diretamente em seu funcionamento. _____________________________________________________________________________
