Bone Grafts
Bone Grafts at Rehan Dental Surgery Karachi is a surgical procedure by which new bone or a replacement material is placed into spaces between or around broken bone or holes in bone to aid in healing. Most bone grafts are expected to be reabsorbed and replaced as the natural bone heals over a few months’ time.

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
With our approach to dental bone graft procedures, using a number of bone resources, the patient’s physical appearance is drastically improved.
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.
The most common use of bone grafting is in the application of dental implants to restore the edentulous area of a missing tooth. Dental implants require bones underneath them for support and proper integration into the mouth. As mentioned earlier bone grafts come in various forms such as autologous (from the same person), Allograft, Xenograft (mainly bovine bone), and Alloplastic materials. Bone grafts can be used prior to implant placement or simultaneously. People who have been without teeth for a prolonged period may not have enough bone left in the necessary locations. In this case, bone can be taken from the chin, from the pilot holes for the implants, or even from the iliac crest of the pelvis and inserted into the mouth underneath the new implant.
