Profile: MPL Technologies, Inc. produces metal dental cartridge syringe. We offer HYPO® brand intraosseous dental needles. Our intraosseous needle is a 30 guage, tri bevel, siliconized needle designed for achieving single tooth anesthesia. Its self limiting design allows for sufficient penetration depth into the cancellous bone. This special feature allows for a one-step, intraosseous injection without the need to pre-drill a perforation hole. Our intraosseous needle has a pre-threaded metal hub that fits any standard dental syringe and may be used for multiple injections per patient.
