Study of Two Different Putty Bone Grafts in Treatment of Intrabony Defects with the Aid of Intramarrow Penetration Technique

"decortication will be performed by penetrating the cortical walls of the intrabony defect by using a round carbide bur of 0.2 mm diameter to reach the marrow space.~* Multiple perforations will performed not closer than 1mm from each other and deep enough to obtain bleeding from the spongiosa~* The intrabony defects in Group I will be received nanocrystalline hydroxyapatite in putty form as grafting material (NanoBone® SBX Putty)."

decortication will be performed by penetrating the cortical walls of the intrabony defect by using a round carbide bur of 0.2 mm diameter to reach the marrow space. • Multiple perforations will performed not closer than 1mm from each other and deep enough to obtain bleeding from the spongiosa • The intrabony defects in Group II will be received Demineralized Bone Matrix allograft putty as grafting material, in both groups will be use membrane to cover of the graft materials and finally will be sutured the flap.
