DSI Premium Spiral Implant Line - Internal HexDSI Premium Line Spiral Implants are tapered self tapping, internal hex implants, enabling easy insertion of the implant into the socket and sustaining exceptional initial stability. It can be used in all bone types. The slightly aggressive geometric shape includes dual threads, two spiral channels stemming from the apex, micro rings on the neck, and a changing thread thickness along with the implant for better stability in immediate loading.
