Objectives.The aim of this case series study was to evaluate, clinically and histologically, the performances of a novel composite xenohybrid bone substitute.
Methods. Ten non-restorable teeth were extracted and socket preservation was performed with a bovine heterologous graft enriched with collagen and resorbable biopolymers (SmartBone®). The socket was covered with a collagen membrane firmly sutured. After five months of healing, implant site was prepared by means of a trephine bur and a dental implant was inserted. Specimens were sent for histological analysis. After three months of healing, patients received a provisional restoration followed by a definitive crown.
Results. All socket preservations healed uneventfully and, after five months, it was possible to insert implants with no additional bone augmentation procedures. All placed implants osseointegrated successfully and were in function after a minimum follow-up period of 30 months.
Conclusions. The tested biomaterial confirmed good clinical performance and, even if left exposed to the oral cavity covered with a collagen membrane, did not show signs of infection. Further research is desirable with a larger sample and variations of socket preservation technique to better understand the potential of this novel bone substitute.
