Hemispherical geometry with polar deflection. ULTRAFIT® finishing along the equatorial rim to maximize press-fit insertion. Surface coated with bio-active materials as pure Titanium and Hydroxyapatite to enhance primary stability and promote biological integration. BIOLOX® ceramic inserts locks into the cup thanks to the taper connection. UHMWPE and VITAL-XE® inserts, more than the taper connection, locks into the cup thanks to a patented locking system which ensures retention and rotational stability. Screw holes are sealed by apposite plugs that can be removed in case additional screw fixation is required.
