[Tibial bone harvesting technique for filling maxillary bone gaps in implantology].
We present an easy and quick technique of tibial bone grafting that can be used in maxillary bone losses, specially in implantology. The surgical technique is performed under general anaesthesia. A 1.5 cm skin incision is made on the anteromedial side of the tibia. Then the bone marrow can be approached through a cortical window drilled with a motorized trephine. At this stage, a disposable bone aspirator is used to collect the cancellous bone. At the end of the procedure, the periosteum, the subcutaneous tissues and the skin are sutured in three layers. The quantity of harvested cancellous bone varies from 18 to 30 cc. The procedure duration is about twenty minutes. The complication rate is low and the patients are able to walk a few hours after the procedure. They leave the hospital on the day after. Tibial bone harvesting is an alternative technique that can be chosen in cases with large bone defects. This tibial graft can be recommended because of its low morbidity, the quality of the bone and the short time duration of the procedure. Some details must be pointed out. A medial tibial surgical approach is for us better than a lateral approach because of its lower morbidity and because the bone is more superficial. The use of a motorized trephine is important to lift precisely the cortical bone window and because it is less traumatic than the hand trephine. The disposable bone aspirator is an excellent option to pick-up bone marrow with a minimum loss of bone material and in a shorter time.
