Enxerto gengival livre para correção de defeitos de tecido mole previamente a cirurgias reconstrutivas

Abstract

A anatomia do tecido mole peri-implantar é semelhante à do dente natural, uma vez que apresenta epitélio juncional e tecido conjuntivo. O selamento peri-implantar é estabelecido pela mucosa ceratinizada que previne a migração apical da margem gengival, mantendo a arquitetura tecidual e estética vermelha ao redor dos implantes osseointegráveis. O presente trabalho objetivou relatar um caso clínico de reconstrução de tecido mole previamente a cirurgia óssea reconstrutiva para a instalação de implante osseointegrável. Após a reconstrução do tecido mole observou-se que houve um satisfatório ganho de altura e espessura tecidual. Foi obtido um volume tecidual suficiente para regularização do zênite gengival e considerável volume de mucosa ceratinizada foi obtida previamente a cirurgia reconstrutiva.Descritores: Implantes Dentários; Periodontia; Reabilitação Bucal.ReferênciasMutthineni RB, Dudala RB, Ramisetty A.
