Long-Term Survival in Grafted Sites of Dental Implants.

Objective: Vertical and horizontal bone insufficiency in both the maxilla and mandible has long been a contraindication for implants. This review provides an overview of the long-term survival rates of implants in augmented alveolar bone after the guided bone regeneration (GBR) technique.
Results: GBR in a combination of allogeneic or xenogeneic graft material with a barrier membrane and simultaneous or delayed placement of dental implants has proven to be a very effective and feasible treatment option in long-term studies up to 35 years.
Conclusion: Bone reconstruction with various materials is a standard therapy in implantology today.
