This technique consists on performing a small groove-like incision around the defect; the incision is deepened along the tooth, creating a ''bag'' so as to later place connective tissue within it.
En esta técnica se realiza una pequeña incisión surcal alrededor del defecto, se profundiza la incisión a lo largo del diente creando una bolsa y posteriormente se coloca el tejido conectivo dentro de la misma.
