Different techniques of bone grafting
If the patient does not need bone harvesting extraorally, there is no need for general anaesthesia. If that is needed the operation will be carried out under general anaesthesia, requiring at least an overnight hospitalisation. The typical donor site is the anterior iliac crest (hip bone). The harvested bone will be stabilised by screws at the recipient site. Though the cells of the donor bone block will lose vitality due to lack of circulation, the bone structure functioning as a scaffold enhances the integration of the own bone.
Regardless of the method of anaesthesia the surgical treatment is completed without causing pain for the patient. In both cases after the operation the area can be sore and swollen which can be easily controlled by painkillers. Sometimes a few days of sick leave could be indicated. The size of the grafted bone is slightly reduced during the healing period by bone transformation. Ultimately, the graft becomes identical in structure to the surrounding recipient area.
The treatment of numerous patients are rejected by clinics with less experience in bone grafting. The reason behind that is likely due to the thin bucco-linqual aveolar processus (bone ridge). Patient with this type of problem can be treated using ridge splitting, sandwich bone grafting and implant setting or with lateral augmentation and gingivoplasty.
After a six month healing period the implants can be inserted into the grafted site. The final integration of the implants takes a further four month.
