There is a wide variety of particulate grafting materials which can be used as a matrix for new osseous regeneration as well as an intermediate space maintainer in the GTR/GBR procedure. They fall into general categories of autogenous, synthetic, allograft or treated animal bone. The matrix should be applied in the least invasive method. Healthy, naturally autogenous bone may be simply and quickly harvested for immediate use.
A conservative, full thickness flap procedure is accomplished in the retromolar or other available site, The cortical and medullary bone can then be removed by use of a slow drilling procedure or with Rongeurs. The Bone Collector instrument is easily introduced into the suction line with an internal Filter Cartridge and suction tip in place. The system’s Aspirator Trip is held in close proximity to the surgical site which draws all extracted bone matter into the system where it is retained in the sterile Filter Cartridge. When the bone harvesting process is complete, the Bone Collector Housing is the separated. The Filter Cartridge and trapped bone material are then recovered. Normal surgical suction can then be resumed by the clinician.
The autogenous bone is removed from the Filter Cartridge and placed into a small, sterile container by use of a gentle scooping motion, It is now ready for placement into any area where bone regeneration is desired. At the discretion of the clinician, the recovered bone may be combined with any number of synthetic or treated foreign bone materials to enhance mass or growth features in the placement site.
When the particulate grafting material has been satisfactorily placed in the desired area, a mechanical barrier should be applied to conserve the graft anatomy and to prevent epithelial invagination.
