Prosthetic components with Friction Fit connection and one conical degree on the wall of the hex abutment, have been developed for S1B, S1TN, SVB and NHSI implant systems with internal hex connection. This connection ensures a “cold fusion” between implant and abutment if the retaining screw has been tightened at 30 Ncm. It eliminates micro-movements and reduces bacterial infiltration between implant and abutment. Prosthetic components with a tilted cone to 16° fit perfectly with our S1T implant system. An external hex connection with “Flat to Flat” joint has been developed for NHSE implant system. iRES® offers different implant solutions to cover a wide range of treatment options and fulfil every surgical need. The NHSIC conical connection has a 5° angle on the abutment and on the implant, and an emergence profile for the mucous attack. The cone-morse connection creates fissures (1µm) smaller than bacteria, absorbs vibration and chewing stress with the result that it eliminates the unscrewing of the screws. There is no connection between implant and abutment in NHSM Onepiece system and this allows to completely eliminate bacterial infiltration. OnePiece connection is perfect for immediate loading.
