Introduction The aim of this randomized clinical trial was to assess the aesthetical and clinical outcomes of acellular dermal matrix graft (ADMG) plus coronally advanced flap (CAF) with vertical incisions or the envelope flap in the treatment of thin phenotype, multiple‐recession defects. Material and Methods Twenty‐two participants with 55 class recession type 1 (RT1) with a depth of ≥3 mm were investigated. Control group was treated with ADMG plus conventional CAF with vertical releasing incisions, whereas test group received the envelope flap with ADMG. Primary outcome variables were complete root coverage (CRC), root coverage aesthetic score and patient satisfaction. Results Tooth‐based CRC was observed in 23 of the 28 recession defects in mCAF + ADMG group (82.1%), whereas in 19 of the 27 recession defects in CAF + ADMG group (70.37%), with no inter‐group difference (p > .05). CRC was observed in 9 of the 11 patients in mCAF + ADMG group (81.8%). On the other hand, in CAF + ADMG group, CRC was achieved in 8 of the 11 patients (72.7%). Results were similar between the groups (p > .05). Conclusions Both techniques were successful in the management of multiple recessions; however, superior results regarding patient's satisfaction were achieved with mCAF + ADMG.
