In this case, we are adding a new method to the standard procedure by advancing the gingival collar coronally to cover the root surface at the same time we are adding the graft to increase the zone of attached gingiva. Note the difference in root coverage before and just one week after the procedure.
Placing the graft directly over the root surfaces at the time of surgery typically doesn’t work, as there is no blood supply to nourish the graft over the root surfaces.
With this technique, the gingival collar that we are advancing maintains its blood supply from the adjacent gingival papillae, and is supported in its new position by the donor tissue.
I had subepthithelial done to tooth number 11 and it did not take. I now have a noticeable band around the front tooth which makes the tooth longer than what is. Can another graft be done after the first graft did not take?
