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.
The patient must be ≥18 years and able to understand the nature of the proposed surgery and must sign an informed consent.
The implant must be located between 2 fixed reference points (i.e. clinical crowns).
Anterior and premolar teeth (from premolar to premolar).
Enough crestal bone width to leave a minimum thickness of 2mm at the buccal bone plate when placing the implant.
Pregnant or lactation.
Active periodontal disease.
Previous soft tissue augmentation in the area.
Need of guided bone regeneration (GBR) during or after the placement of the implant.
