腫瘍切除後にオンレーボーングラフトとオッセオインテグレーテッドインプラントにより咬合再建を行った3例

抄録

This report describes three cases who underwent mandibular reconstruction by onlay bone graft and osseointegrated implants after tumor resection.
The advantage of using osseointegrated implant with onlay bone graft after tumor resection is prevention of pathologic fracture and longer implant placement.
Prominent resporption of grafted bone in one of three cases was observed.
The reason for resorption was considered to be the long time from implant placement to loading, and poor quality of the grafted bone.
