The mandibular body bone (MBB) graft: an alternative source of membranous bone

The use of mandibular body bone (MBB) as an alternative source of membranous bone graft is described. The MBB technique is a simple, safe and rapid method of obtaining cortical bone for grafting. Furthermore MBB is membranous bone, which has been reported to be more dimensionally stable after grafting than is endochondral bone. The donor site is more readily accessible than is that for cranial bone, the other source of membranous bone. Two 1.5 x 3 cm rectangular grafts are generally available. We recommend the use of MBB in situations where the technique provides sufficient bone.
