Particulate bone grafts can be defined based on their source of obtainment as autografts, allografts, xenografts and alloplasts. Autografts and allografts have human origins, where autografts are tissues transplanted within the same individual from one part of the body to another and allografts are those that are surgically transplanted from one individual to another. Xenografts are tissues that are transplanted from one species to another. Alloplasts on the other hand are synthetic/ man-made and are manufactured from various materials to facilitate guided tissue and bone regeneration.
