Mini Extragrade straight abutment with screw and castable sleeve for bonding technique. Available in two diameters.
They are also recommended when the prosthetic screw hole can create aesthetic problems in the fixed denture; thanks to the square purple screw, the screw hole can be inclined by 25 degrees and has areduced diameter compared to the blue square prosthetic screw. In case of particularly inclined implants it is possible to omit one screw (e.g. one out of four in an all-on-four denture), using the undercut of the Ot Equator as a retentive area for the Seeger.
With divergent implants, the extragrade abutment must be inserted with the external flat
milled surface in correspondence of the maximum undercut of the Ot Equator.
