Avaliação quantitativa do osso palatino para orientação da inserção de mini-implantes ortodônticos: análise por TCFC

Palavras-chave: Tomografia Computadorizada de Feixe Cônico, Palato, Processo Alveolar, Procedimentos de Ancoragem Ortodôntica

Resumo

Introdução: O uso de mini-implantes tem se tornado comum na prática ortodôntica por aumentar a possibilidade de ancoragem esquelética. O palato constitui um local de escolha para a inserção de mini-implantes por ser um local com relativa segurança, espessura óssea adequada e menor chance para inflamação. Objetivo: Avaliar quantitativamente a espessura do osso palatino para inserção de mini-implantes. Material e Métodos: Foram selecionados 47 conjuntos de imagens de tomografia computadorizada de feixe cônico (TCFC). A amostra foi composta por 20 homens e 27 mulheres (idade média de 22 anos; ± 3 anos). A espessura óssea palatina (EOP) foi medida em milímetros (mm) em 5 regiões de interesse (ROIs) delimitadas em vistas coronais da área patatal 4, 6, 8 e 10 mm posteriores ao forame incisivo. Resultados: Foram avaliados 940 ROIs. Diferenças significativas foram observadas para EOP entre várias seções palatais (p <0,01). A área mais espessa (6,31-7,03 mm) foi encontrada na parte anterior do palato. As espessuras ósseas médias nas seções de 6, 8 e 10 mm foram significativamente menores que as observadas a 4 mm do forame incisivo. Conclusões: A espessura do osso palatino diminui do forame palatino para a região posterior. Transversalmente, o osso era mais espesso na sutura palatina do que nas áreas paramedianas, principalmente nas secções coronais mais laterais.
