Abstract
|
|
|
The purpose of this study was to compare the tissue response between the autogenous intramembranous bone and the autogenous endochondral bone grafted into the extraction socket of the rabbit.
After the anterior teeth extraction, sockets were filled by the particulated cranial bone or by the particulated iliac bone.
The rabbits were sacrificed at the 1st day, 3rd day, 1st week, 2nd week, 4th and 6th week after bone grafting. And the specimens were examined with light microscope.
@ES The results were as follows :
@EN 1. New bone formation with osteoblastic activity was observed on the cranial bone grafting area.
2. Trabecular patterns were shown in the 1st week specimen of the cranial bone grafting group, and were shown in the 2nd week specimen of the iliac bone grafting group.
3. 6th week after iliac grafting, maturation of endochondral bone with compact collagen deposition was observed.
4. 6th week after cranial bone grafting, compact bone pattern with dense fibrous tissue was observed.
