由於大部份的概念在以前都有學過,加上我們組並沒有打中文講稿,所以先跟大家說聲抱歉
重點只好先用英文敘述, 如果有看不懂的請提出 ^^*
--------------------------------------------
Osteogenetic : the ability to form new bone in a graft by transplanting viable
osteoblasts
Osteoconduction :the formation of new bone along a scaffold from the host's
osteocompetent cells.
Osteoinduction : the ability of the graft to stimulate differentiation of
mesenchymal cells into osteoblasts at the recipient site.
-----
Autogeneic:grafts transferred from one position to another within the same
individual .
Allogeneic:grafts transferred between genetically dissimliar members of the
same species.
Xenogeneic: grafts taken from a donor of an other species.
Alloplastic: synthetic or inorganic implant materials which are used as
an subsitude for bone grafts.
-----
[Autogeneic grafts]
優點
贯 Have all three bone regeneration properties (Osteogenic, Osteoinductive,
Osteoconductive)
贯 Histocompatability and disease transmission are eliminated.
缺點
贯 Limited supply
贯 Increased operation time
贯 Second surgical site
贯 Increased postsurgical morbidity
[ALLOGENIC BONE GRAFT]
優點
贯 Osteoconductivity (some have osteoinductivity,例如:DFDBA)
贯 Good supply
贯 Eliminate harvesting morbidity
缺點
贯 Weakened as it remodels
贯 More expensive
贯 Risk of disease transmission(因為是別人的,可能會有疾病傳染的疑慮)
[Xenogeneic bone graft]
優點
贯 Osteoconductivity
贯 Good supply
贯 Eliminate harvesting morbidity
缺點
贯 Weakened as it remodels
贯 More expensive
贯 Risk of disease transmission
[ALLOPLASTIC BONE GRAFT]
synthetic bone graft substitutes ; osteoconduction.
優點
贯 Safe.
贯 Non-infectious and non-immunogenic potential.
贯 Readily available(供應無虞)
贯 Excellent bone bonding capacity
缺點
只有osteocondution的能力
