Vascularized and Nonvascularized Free Bone-Grafts for Mandibular Defects in Dogs / 第二军医大学学报

ABSTRACT

An experimental study of vascularized and nonvascularized free bone-grafts for mandibular defects in dogs was conducted.The different bone healing process was observed by histological study.The results show that with 3 cm-length bone graft either vascularized or nonvascularized its healing process is similar.Both bones of donor and receptor have osteogenic activity.This process is similar to that of fracture healing.
