Sponsor's own description
The present study aims to compare the tunnel technique/laterally closed tunnel technique and the FGG technique in the treatment of isolate/multiple GR in the anterior region of the mandible. Furthermore, it is proposed to evaluate the effect of a gel based on hyaluronic acid and green tea on the healing of the donor area after the removal of FGG from the palate. This work is expected to contribute to the still uncertain literature on the effectiveness of the tunnel technique as an alternative to the use of FGG in the treatment of multiple GR in the mandible.
