Bone Grafting is a surgical procedure that replaces missing bone with material from the patient’s own body, an artificial, synthetic, or natural substitute.

Easy- Graft Principles:
easy-graft™ products are bioresorbable, completely synthetic bone graft substitutes for bone defects. They consist of two components: Granules and BioLinker™. When combining these two components, the easy-graft™ material becomes a putty-like biomaterial and can be applied directly from the syringe into the bone defect. In contact with body fluids such as blood or saliva the material hardens within minutes and forms a stable, porous bone substitute material. Due to the porosity of the material, the absorption of blood is possible and thus positively influences the healing process.

Fields of Application
To do a beautiful smile makeover, a dentist needs a passion for beauty and a personality that loves to create things of beauty. Few dentists have this artistic inclination. Our team always pursues additional training to learn the skills necessary to create smiles – training in special bonding techniques, color manipulation, and in understanding of the special materials that are used in this highly specialized area of dentistry.
Biological mechanisms governing bone grafting
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 biologic mechanisms that provide a rationale for bone grafting are osteoconduction, osteoinduction and osteogenesis. Osteoconduction Osteoconduction occurs when the bone graft material serves as a scaffold for new bone growth that is perpetuated by the native bone. Osteoblasts from the margin of the defect that is being grafted utilize the bone graft material as a framework upon which to spread and generate new bone. In the very least, a bone graft material should be osteoconductive. Osteoinduction Osteoinduction involves the stimulation of osteoprogenitor cells to differentiate into osteoblasts that then begin new bone formation. The most widely studied type of osteoinductive cell mediators are bone morphogenetic proteins (BMPs). A bone graft material that is osteoconductive and osteoinduction will not only serve as a scaffold for currently existing osteoblasts but will also trigger the formation of new osteoblasts, theoretically promoting faster integration of the graft. Osteogenesis Osteogenesis occurs when vital osteoblasts originating from the bone graft material contribute to new bone growth along with bone growth generated via the other two mechanisms.

Types and Tissue Sources
Autograft Autologous (or autogenous) bone grafting involves utilizing bone obtained from the same individual receiving the graft. Bone can be harvested from non-essential bones, such as from the iliac crest, or more commonly in oral surgery, from the mandibular symphysis (chin area) or anterior mandibular ramus (the coronoid process); this is particularly true for block grafts, in which a small block of bone is placed whole in the area being grafted. When a block graft will be performed, autogenous bone is the most preferred because there is less risk of the graft rejection because the graft originated from the patient’s own body. As indicated in the chart above, such a graft would be osteoinductive and osteogenic, as well as osteoconductive. A negative aspect of autologous grafts is that an additional surgical site is required, in effect adding another potential location for post-operative pain and complications. Autologous bone is typically harvested from intra-oral sources as the chin or extra-oral sources as the iliac crest, the fibula, the ribs, the mandible and even parts of the skull. All bone requires a blood supply in the transplanted site. Depending on where the transplant site is and the size of the graft, an additional blood supply may be required. For these types of grafts, extraction of the part of the periosteum and accompanying blood vesels along with donor bone is required. This kind of graft is known as a free flap graft.
Allografts Allograft bone, like autogenous bone, is derived from humans; the difference is that allograft is harvested from an individual other than the one receiving the graft. Allograft bone in taken from cadavers that have donated their bone so that it can be used for living people who are in need of it; it is typically sourced from a bone bank. There are three types of bone allograft available: Fresh or fresh-frozen bone Freeze-dried bone allograft (FDBA) Demineralized freeze-dried bone allograft (DFDBA)
