Why bone grafting?
The loss of a tooth causes the progressive resorption of the jaw bone. When bone loss is frequent, dental implantology can not intervene and place a dental implant into an area that is too narrow. It is necessary to carry out a bone graft beforehand.
What is bone grafting?
In most cases, the grafts are performed under local anesthesia most often. Grafts, performed under general anesthesia involve hospitalization and a long recovery period. Bone removed from the jaw may be applied in cases of significant increases in bone peaks or if the quality of the bone in the jaw is unsuitable.
Bone elevation with graft
it is called alloplast. This is a synthetic bone graft developed in a laboratory. In dental implantation generally it contains Hydroxyapatite (a major component and an essential ingredient of teeth).
in this case, we use processed bone that comes from animals (cow, horse, or pig bone). Using bovine bone is a proven and successful technique. The method is efficient, because the bone graft prevents the collapse of the surrounding tissues. During the so called “guided tissue regeneration” process, the human body recognizes the graft as natural bone. These grafts make a framework for bone from the surrounding area to grow and fill the hole.
Bone transplantation - Autograft
The graft, a piece of bone, is taken from the patient in the jaw, chin, hip, tibia or skull (external wall) and is usually immobilized by one or more osteosynthesis screws.
Duration of bone grafting
Approximately 30mn to 3h depending on the type of graft performed under local anesthesia in the office under neurolepal analgesia + local anesthesia or under general anesthesia for bone grafts with tibia, hip or skull sampling.
- Additional time
Depending on the complexity of the graft to be performed, the increase in the bone volume can be carried out simultaneously or prior to the placement of the implants. If the bone graft is done beforehand, the placement of the dental implants is deferred approximately 3 to 8 months in order to obtain the vascularization of the graft.
- The simultaneous transplant
In some cases, implant placement can be done simultaneously.
Cost of bone grafting
If a bone graft is necessary, it must be the subject of a supplementary estimate. The cost of a bone graft is between 600 and 5000 Euros in France, between 500 and 2500 Euros in Hungary.
Management of bone graft
No social security coverage for this act of surgery Outside Nomenclature (HN).
Constraints and risks of bone grafting
Depending on the sampling site, the disadvantages may include a “tape” on the chin, sensory disturbances in the chin and lower lip or limited tonsure (for bone removal from the skull) . Wearing of any dental prosthesis is not recommended for several months.
The realization of a graft, like any act of surgery, is subject to a therapeutic hazard. In case of infection, graft loss or a result not allowing the implantation of implants.
Maxillofacial surgery offers the possibility of reconstructing large and tall bone sites. The oldest edges, the most resorbed ridges, the almost non-existent bone are no longer insurmountable problems. A maxillofacial surgeon is able to recreate ideal conditions, both anatomically and aesthetically. Don’t forget to pay attention to the costs, risks and constraints.
