Bioactive grafts are grafts that are coated with substances that promote healing and reduce the risk of graft failure. These substances can enhance the integration of the graft with the native blood vessels, leading to improved outcomes. Bioresorbable grafts, on the other hand, are grafts that are designed to be gradually absorbed by the body over time, leaving behind only the patient's own natural blood vessels. This eliminates the need for permanent foreign material in the body and may reduce the risk of long-term complications associated with graft materials.
