BONE GRAFTS

A. AUTOGENOUS GRAFTS – AUTOGRAFT
a. From same individual – different donor site
b. Best graft For osseous defect– cancellous graft (since they have pores for blood vessels to pass)*
c. Eg: bone coagulum
d. Best extraoral donor site:
i. Post surface of iliac bone (nerve supply here is iliogastric nerve)
ii. Best graft for condyle of mandible
1. 5th and 6th costocondral graft
2. 6th and 9th rib graft for ridge augmentation

B. ALLOGENOUS GRAFT – HOMOGRAFT
a. From same species – different individual
b. DFDBG – Decalcified Freeze dried Bone Graft
i. For grade 2 furcation involvement
ii. Best for osseous defect is – DECALCIFIED CANCELLOUS FREEZE DRIED BONE GRAFT*

C. XENOGRAFT GRAFT
a. Graft from different species, POVINE GRAFT FOR EG.

D. ALLOPLASTIC GRAFT
a. From inorganic substance
b. Eg: hydroxyapatite
E. Graft from identical twins – ISO GRAFT
F. Condyle : post chondral graft
G. Child for alveolar process : iliac crest
H. 3 wall defects in adult : mixed cortical and cancellous from his own intraoral mixed with his blood.
I. 2 wall defect in perio --> Cancellous freeze dried bone allograft*
