A New Collector Device for the Immediate Use of Particulate Autogenous Bone Grafts

Abstract

Autogenous bone grafts can be harvested from either intraoral or extraoral sources. Intra-oral sources include healing tooth extraction wounds, a bone from edentulous ridges, bone trephined from within the jaw using trephine drills, bone formed in wounds, and bone from the maxillary tuberosity, ramus, and mandibular symphysis. Extra-oral sources are the iliac crest, which provides cancellous bone marrow, and the tibia and calvaria. Autogenous bone grafting aids in probing depth reduction, gaining clinical attachment, the bone filling of osseous defects, and the regeneration of new bone, cementum, and periodontal ligaments in teeth. An innovative biomedical device is presented in the form of an autogenous bone collector that can fill defects of 96.91 mm3 with bone particulates, and may be used in bioengineered scaffolds. Experimental studies on synthetic bone have demonstrated the feasibility and applicability of the amount of bone obtained.
