RESUMO

O presente relato de caso teve como objetivo comparar o uso do retalho avançado coronal (RAC) associado a um enxerto de tecido conjuntivo (ETC) com retalho avançado coronal (RAC) associado à matriz dérmica acelular xenógena (MDX), no tratamento de recessões gengivais múltiplas Classes I de Miller, em um relato de caso clínico randomizado de boca dividida. Um paciente com recessões múltiplas bilaterais Classe I de Miller foi selecionado para o estudo, e o tratamento foi realizado em cada lado da maxila (RAC + ETC ou RAC + MDX) de forma aleatória. Os seguintes parâmetros clínicos foram avaliados no início, após seis meses e um ano após a cirurgia: recessão gengival (RG), altura do tecido queratinizado (TQ), nível clínico de inserção (NCI) e profundidade de sondagem (PS). Clinicamente, os resultados do presente relato de caso mostraram que os dois métodos (RAC + ETC e RAC + MDX) são efetivos para o tratamento de recessões múltiplas maxilares Classe I de Miller, com ganhos similares de TQ, nível de inserção clínica, redução da profundidade de sondagem e recobrimento radicular.

Palavras-chave – Recessão gengival/cirurgia; Recessão gengival/tratamento; Matriz dérmica acelular; Enxerto de tecido conjuntivo.

ABSTRACT

The present case report aimed to compare the use of a coronal advanced flap (CAF) associated with a connective tissue graft (CTG) with a coronal advanced flap (CAF) associated with a xenogeneic acellular dermal matrix (XDM) in the treatment of Miller’s Class I multiple gingival recessions in a split-mouth randomized clinical case report. A patient with Miller class I bilateral multiple recessions was selected for the study, and treatment on each side of the maxilla (CAF + CTG or CAF + XDM) was randomly assigned. Clinical parameters such as gingival recession (GR), height of keratinized tissue (KT), clinical attachment level (CAL) and probing depth (PD) were assessed at baseline, 6 months and 1 year after surgery. Clinically, the results of the present case report showed that both treatments, CAF + CTG or CAF + XDM, are effective for the treatment of Miller Class I multiple maxillary recessions, with similar gains in KT, CAL, and reductions in PD and GR.

Key words – Gingival recession/surgery; Gingival recession/ treatment; Acellular dermal matrix; Connective tissue graft.
