Bone Grafts
Overview
Bone Grafts at Rehan Dental surgery Karachi
After tooth removal, frequent re-absorption of the adjacent bone occurs, the result of which is loss of bone stature and breadth. As bone reabsorbs the overlying tissue can lose volume and its typical anatomic form. This lack of bone and gum tissue that follows tooth extraction frequently results in function loss and aesthetic defects, resulting in an unpleasant collapsed look.
Bone Grafts Approach
Bone Grafts Principal
The principles involved in successful bone grafts include osteoconduction (guiding the reparative growth of the natural bone), osteoinduction (encouraging undifferentiated cells to become active osteoblasts), and osteogenesis (living bone cells in the graft material contribute to bone remodeling). Osteogenesis only occurs with autograft tissue and allograft cellular bone matrices.
Bone grafting is possible because bone tissue, unlike most other tissues, has the ability to regenerate completely if provided the space into which to grow. As native bone grows, it will generally replace the graft material completely, resulting in a fully integrated region of new bone. The biological mechanisms that provide a rationale for bone grafting are osteoconduction, osteoinduction, and osteogenesis.
