Abstract
Soft tissue augmentation procedures are often performed to correct mucosal recession on the facial aspect following implant restoration in the esthetic zone. This case report illustrates a novel approach of correcting mucosal recession around maxillary implants using guided bone regeneration (GBR) xenogenic resorbable membrane, and particulate allograft. A 22 year-old male patient presented with gingival recession and discoloration due to exposure of the 3 underlying dental implants in the maxillary esthetic zone 3 years after implant placement. Patient had bone loss confined to the labial surface of the implants, but no peri-mucositis/implantitis was present. A solvent-dehydrated mineralized allograft (Puros Cancellous Bone Allograft, Zimmer Biomet Dental, Palm Beach Gardens, FL) and a resorbable membrane (CopiOs Pericardium, Zimmer Biomet Dental) were used in a GBR surgical procedure in combination with placement of roughened titanium tenting screws 3-4 mm below the implant platform to restore unesthetic defects. Followup after 8 years showed that the allograft and xenogenic membrane effectively corrected bone defect, and increased the keratinized tissue width and gingival height in the esthetic zone of the anterior maxilla.
