At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
Grafts are inserted through a tunnel that is drilled through the shin bone (tibia) and thigh bone (femur). The graft is then pulled through the tunnel and fixated with screws. The two bright objects in this X-ray are screws in the thigh bone (above) and shin bone (below). Graft options for ACL reconstruction include:
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.

This is because the patient's body needs to adapt to the foreign material and integrate the alloplastic implant or graft with its surrounding tissue. [ 5 ] [ 19 ] The surgical technique of alloplasty if completed incorrectly can cause significant and irreversible damage to surrounding nerves by the improper placement of osteotomy.
Holes to accommodate a replacement graft tendon are drilled in the ulna and humerus bones of the elbow. [10] A harvested tendon, such as the palmaris tendon [ 11 ] from the forearm of the same or opposite elbow, the patellar tendon , hamstring, toe extensor or a donor's tendon ( allograft ), is then woven in a figure-eight pattern through the ...
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. [20]
In cleft palate patients bone grafting during the mixed dentition has been widely accepted since the mid-1960s. The goals of surgery are to stabilize the maxilla, facilitate the healthy eruption of teeth that are adjacent the cleft, improving the esthetics of the base of the nose, create a bone base for dental implants, and to close any oro-nasal fistulas.
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as the replacement of such structure supported by dental implants. [1]
