Straumann® SocketPlug is a calcium phosphate-based mineral with a synthetic carbonate apatite structure physically and chemically comparable to the matrix of human bone. The similarity in structure between the SocketPlug mineral and natural anorganic bone mineral mimics natural bone as shown in vivo resorption and remodeling profile. The low crystallinity of carbonate apatite supports bioresorption and the synthetic mineral has been shown to increase the bone forming activities of osteogenic cells as well as enhance bioresorption of bone by osteoclasts. The makeup of the SocketPlug is approximately 80% mineral combined with 20% Type I Achilles bovine tendon collagen.
