Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.

Control Group

Implant placement and prosthetic rehabilitation of the missing tooth

Group Type ACTIVE_COMPARATOR

Implant Placement

Intervention Type PROCEDURE

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.

SCTG group

Implant placement, soft tissue augumentation of Connective Tissue Graft (from the palate) (SCTG) at the implant site and prosthetic rehabilitation of the missing tooth.

Group Type EXPERIMENTAL

Soft Tissue graft augmentation

Intervention Type PROCEDURE

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
