Acellular dermal matrix for the treatment of multiple gingival recession defects associated with carious and previously-restored cervical lesions: a case report with 10 years of follow-up.

INTRODUCTION: Limited evidence exists on the outcome of the modified coronally advanced tunnel (MCAT) with acellular dermal matrix (ADM) for the treatment of gingival recession defects (GRD) especially when complicated by restored cervical lesions. Therefore, the aim of this case report was to assess the short- and long-term clinical outcomes of maxillary Type 1 recession defects (RT1) associated with restored cervical lesions treated with MCAT with ADM.

CASE PRESENTATION: A 43-year-old female patient, presented with multiple adjacent RT1 recessions in the left maxilla, previously treated with overhanging cervical resin restorations. The case was approached with a careful evaluation of the diagnostic determinants of root coverage, removal of the aberrant resin restorations, treatment with MCAT with ADM, and periodical evaluation over a follow-up of 10 years. The treatment was followed by complete root coverage, improvement of gingival phenotype and perfect root coverage esthetic score. Outcomes were periodically assessed, and were maintained over 10 years of follow-up.

CONCLUSION: MCAT with ADM is an effective technique for the treatment of multiple GRD complicated by cervical restorations. Complete root coverage and excellent esthetic outcomes were obtained and maintained in the long term. This article is protected by copyright.
