Behavioral Comparison of Three Different Graft Materials to Increase Soft Tissue Thickness Around Dental Implants.

"Donor site:~SCTG group: The SCTG will be harvested in the palat,In order to extract the same thickness in each grafts a double-bladed knife (separated by 1,5mm) will be used. The donor area will be sutured.~Recipient site:~SCTG group: the connective tissue graft will be trimmed to the correct dimensions (10mm height, 12mm length and 1,5mm thick) and placed and secured at the recipient site with a resorbable 5-0 suture CM group: The CM graft (Geistlich Fibro-gide) will be trimmed to the indicated dimensions (10mm height, 12mm length) and placed and secured at the recipient site with resorbable 5-0 suture PADM Group: the ADM (NovoMatrix, Biohorizons, Birmingham AL) graft will be trimmed to the indicated dimensions (10mm height, 12mm length) and placed and secured at the recipient site with resorbable 5-0 suture"

A crestal incision will be made in the implant reception area, extending from the distal of the most mesial tooth to the mesial of the most distal tooth. A mucoperiosteal flap will be elevated in the most crestal part of the ridge. The receptor bed will be prepared following the established drilling protocol for the placement of a BioHorizons Tapered Pro Implant (Biohorizons, Birmingham AL). The diameter and length of the implant will be previously established during the implant study. Later a healing abutment will be placed.
