Abstract
Treatment of multiple recession defects on the lingual is challenging owing to the site-specific anatomical features of this region. Surgical approaches based on the use of subepithelial connective tissue grafts are considered the “gold standard” for the treatment but represent various complications and morbidity. Various techniques have been suggested for the treatment of multiple adjacent recessions with less patient discomfort and enhanced esthetics. Advanced platelet-rich fibrin (A-PRF) has been shown to promote soft-tissue healing. A-PRF is a fibrin matrix network, in which platelets are trapped and release a high amount of growth factors which take part in soft tissue and hard tissue repair and regeneration. The current case report introduces a novel, minimally invasive predictable approach applicable for both isolated as well as multiple defects with the use of the (vestibular incision subperiosteal tunnel access) technique in combination with a multilayered A-PRF membrane.
