About

The primary aim of this study is to evaluate whether the use of a xenogenic collagen matrix (XCM) for the treatment of multiple adjacent gingival recessions (MAGRs) with a multiple coronally advanced flap technique (mCAF) achieves better results than the use of an autologous connective tissue graft (CTG) in terms of recession reduction (primary outcome) and other secondary root coverage outcomes (e.g. complete root coverage, mean root coverage). Moreover, this study aims to compare secondary clinical variables (e.g. keratinized tissue width (KTW) changes, probing pocket depth (PPD) changes, volumetric gain (VG), etc.), also with a digital approach, the patient-reported outcome measures (PROMs e.g. pain, swelling, bleeding). The hypothesis of this study is that at 6 months and 1 year follow-up the mCAF with XCM is not inferior to CTG in terms of recessions reduction and secondary clinical variables, and superior regarding to PROMs.

Inclusion criteria

• At least 18 years old and able to sign informed consent
• At least 2 adjacent teeth with RT1 and/or RT2 gingival recessions without interproximal exposure of the CEJ (interdental gingival recession), at least one with a depth of ≥2mm with indication for root coverage treatment
