The use of a new collagen matrix to support the regeneration of peri-implant soft tissue laser-assisted: case report

Several factors compete for both the achievement and the long-term maintenance of osseointegration; among these, of importance is the width and integrity of the peri-implant soft tissue. Many authors already underlined the importance for implant-prosthesis procedures to maintain a good biological seal together with a low bacterial cell surface charge (this is also valid for a natural tooth with an undamaged periodontium). The aim of this work is to present, through a clinical case, a new technique that focuses on the regeneration of soft tissue around a post-extractive implant. For the case reported, a post-extractive implant surgery of an inferior molar of the fourth quadrant with a buccal bone resorption of 3mm in the mesial section of the root, three dimensional collagen matrices (Bioteck) and a blend of equine spongy bone granules (OX Bioteck) were used, combined with aPDT without dye (Rey Protocol). With an easy and not invasive surgery, this technique allows the recreation of new gingiva around the implant.
