Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
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.
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.
Xray showing a sinus lift in the left upper jaw Sinus lift surgery, 3D Illustration. Maxillary sinus floor augmentation [1] (also termed as sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure that aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian ...
A Phemister graft is a type of bone graft which uses bone tissue harvested from the patient to treat slow-healing, or delayed union bone fractures. [1] Thus, it is a form of autotransplantation. Typically, the tissue used in the graft is cancellous bone harvested from the patient's Iliac crest and laid in strips across the fracture site.
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. [3]
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:
Alternatively, bone defects are graded from A to D (A=10+ mm of bone, B=7–9 mm, C=4–6 mm and D=0–3 mm) where an implant's likelihood of osseointegrating is related to the grade of bone. [44]: 250 To achieve an adequate width and height of bone, various bone grafting techniques have been developed.
