Nobel Biocare SCREWS

Fig. 1
Nobel Biocare includes final screws (Fig.1) with each abutment as a
complete kit, although final screw should not be used for the abutments
during the restoration fabrication process. Separate laboratory
screws (Fig.2) are offered by Nobel for this
Fig. 2
purpose and must be purchased
separately. Each screw can be serviced with a Unigrip driver.
NP abutment screws (Fig.1, 2 left) are machined differently than RP/WP abutment screws
(Fig.1, 2 right)
and can not be interchanged from platform to platform. Titanium and
zirconia abutments share the same screw design unlike NobelReplace,
Replace Select and Brånemark System abutments.

Final screws (Fig.3) are included with each abutment as a complete kit,
although final screws should not be used for the abutments
during the restoration fabrication process. Separate laboratory
screws (Fig.4) are offered by Nobel and each screw can be serviced with a
Unigrip driver regardless of laboratory or final screw. Each
platform diameter (NP 3.5, RP 4.1, WP 5.0mm) screw has its own
Fig. 4
dimensions and can not be interchanged from platform to platform.
Laboratory screws are silver in color to differentiate the screws from
final screws while final screws are colored black with the exception of
NP platform final screws. NP platform final abutment screws are silver
in color. Screws for titanium (Fig.3, top row) and zirconia (Fig.3, bottom row) abutments differ slightly and
should not be interchanged

NNNobel Biocare includes final screws (Fig.5) with each abutment as a
complete kit, although final screw should not be used for the abutments
during the restoration fabrication process. Separate laboratory
screws (Fig.6) are offered by Nobel. Each screw can be serviced with a Unigrip
driver. Zirconia (Fig.5, bottom row) and titanium (Fig.5, top row) abutment screws are machined to different
dimensions and should not be interchanged. NP (3.5mm) platform screws
(Fig.5, 6 left) work only within the NP platform group while RP (4.3mm), WP (5.0mm) and
6.0mm platform screws (Fig.5, 6 right) are interchangeable from platform to platform as
long as the
Fig. 6
appropriate abutment material screw is utilized. Final screws
for NP platform zirconia and titanium abutments are silver colored while
final screws for all other platform group titanium abutments are colored
a dull black color. RP, WP and 6.0 final screws for zirconia abutments
are machined with a longer shaft and a shiny black surface finish with a
silver colored head. Laboratory screws are manufactured with a silver
color, regardless of the platform diameter.
