Abstract
Soft and hard tissue volume around natural teeth and dental implants, is crucial for esthetics and long-term maintenance. Studies have described guided bone regeneration (GBR), as a predictable method to maintain or augment hard tissue volume, around teeth and dental implants. For soft tissue volume, collagen matrix showed reliable results, and less post-operative pain in many studies. The purpose of this case report, is to assess the outcome of GBR with volume stable collagen matrix (VSCM), around natural teeth and dental implants. In two cases, GBR with VSCM was performed, to augment soft and hard tissue volume around natural teeth and dental implants, respectively. Both cases showed clinically acceptable esthetics and periodontal parameters, up to 6 and 12 months per respective follow up. As our results show, GBR using VSCM can achieve successful outcomes.
