# 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. Intraoral 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. bone graft; autogenous transplant; bone collector; biomedical devices; bone defect +

bone harvested from inside the jaw using trephine drills, bone formed in wounds, and bone harvested from the maxillary tuberosity, ramus, and mandibular symphysis [9; 10; 11; 12; 13]. Extra-oral sources are the iliac crest, which provides cancellous bone marrow, and the tibia and calvaria. Extra-oral sources may cause post-operative infection, increased patient costs, and difficulty in finding donor material [9; 10; 11; 12; 13; 14]. There are several techniques and devices for harvesting bone grafts, depending on the patient's needs, location, and size of the bone defect. These include the bone scraper, which removes bone by scraping, rotary instruments such as drills or trephines, bone chisels, rongeurs, and piezoelectric devices [9; 14]. Bone dust collected during the use of high-speed drills has several applications, and could be a useful source of viable osteogenic material in spinal, cranial, and craniofacial procedures, wherein a bone collection device can be connected to a standard aspiration circuit and used to collect this bone dust [15]. The development of a bone collection device with which autogenous bone is removed with a simpler and less traumatic procedure is desirable for surgeons and patients choosing the source and/or donor region of the bone graft. Surgery for dental implants has proven over the decades to be a safe procedure, and is well accepted by patients in relation to surgical trauma and its results. The use of a bone collection device in which the same procedures are applied in dental implantation makes the act itself similar the surgeon's normal routine, and we can predict similar expected results in terms of the patient's acceptance [1; 3]. The new mechanical device, bioactive kinetic screw (BKS), described here is a simple multifunctional machine able to simultaneously drill and screw, measure the volume density of the material where it is applied, and compact the material inside [16; 17; 18; 19; 20]; here, we also describe another application, wherein the material collected in the device's interior volume can be used for transplantation to other regions for bone filling, or be used as a stimulus of osteogenesis, osteoinduction, and osteoconduction in bone scaffolds. The idea of reusing bone from bone drilling during dental implant insertion creates the concept of the BKS model as a bone collector [8; 16; 17; 18; 19], which allows simultaneous drilling and screwing, and insertion of the cut material (bone chips) into the internal volume of this new BKS implant model, to then be transplanted. The BKS can be manufactured in a variety of sizes to suit specific requirements and applications. These sizes can be modified internally (through flute length and width, diameter, and position in relation to the longitudinal axis of the through hole), as can the length and overall diameter of the screw.
