Never Loss Bone Collector KitThe Never Loss Bone Collector kit is used to collect autogenous bone with the use of bone collecting drills with stoppers. These drills create an osteotomy by producing small chips of bone which are gathered into the stopper. The stopper can then be removed, exposing the autogenous bone. A bone pusher is included to extrude the harvested bone. This makes the collection of autogenous bone predictable and simple.
