上顎洞底挙上術のための脛骨からの骨採取法

抄録

Various materials for sinus lifting have been used for this type of transplantation, including autologous bone, heterogeneous bone, and artificial bone. A number of reports indicate that the transplantation of fresh autologous bone yields excellent results. If the amount of bone needed for transplantation is small, the necessary bone can be harvested from the mandible(the ramus of the mandible, mental region, etc.),and if a larger amount of bone is needed, the iliac bone can be used as the donor site. The iliac bone is a good source, since large amounts of bone can be harvested from it,including both blocks and fragments. However,bone collection from this area requires more complex surgery, which entails many problems, such as the stress associated with the surgical wound and the more complex facilities required for the operation. Large amounts of cancellous bone for transplantation can be collected from the tibia under local anesthesia, and this site is among the more suitable donor sites if the bone is to be harvested during day surgery. In this article, we present a method for collecting bone from the tibia, citing a case in which this method was employed to obtain bone needed for transplantation.
Conclusion:The combination of bone donation from the tibial head and sinus lifting is considered an excellent means for creating a suitable substructure for implants in patients with severe atrophy of the alveolar ridge, associated with less physical stress.
