The present controlled clinical study has demonstrated that in root surface coverage, a microsurgical approach substantially improved the vascularization of the grafts and the percentages of root coverage compared with applying a conventional macroscopic approach.

The implant sites revealed a substantial, clinically significant improvement following coronal mucosal displacement in combination with connective tissue grafting, but in none of the sites, a could complete implant soft tissue dehiscence coverage be achieved.

The wound depth at the donor site (graft thickness) was positively correlated with the patient's perception for pain. The wound surface area, however, did not influence the perceived pain level.
