| Outline of Final Research Achievements |
In this present study, the effects of bone growth factor and bone substitute on the bone augmentation by three-dimensional (3-D) and histopathological evaluation were examinated. 3-D evaluation was used cone bean CT and histopathological was HE staining and TRAP or ALP immunostaining. The bone augmentation was performed by the materials using autologous bone alone and the mixed bone growth factor (PRP or CGF) and a bone substitutes (HA or HA + b-TCP or b-TCP). The bone augmentation using only bone growth factor was not sufficiently observed on the 3-D and histopathological evaluation. On the other hand, the bone augmentation using the materials mixed bone growth factor and bone substitute is observed enough.
The bone resorption on this bone was small than that on the bone using the autologous bone alone.
