Astra Tech ABUTMENTS
OsseoSpeed™
TiDesign™ abutments are manufactured with a hex for indexing and are
packaged as a kit with a final screw. TiDesign™ stock titanium abutments
are available for all three (3.0 yellow, 3.5/4.0 aqua, 4.5/5.0 lilac)
implant/abutment interface connection groups.
3.0 TiDesign™ abutment
3.0 TiDesign™ abutments
are machined with a emergence profile of 4.0mm and a choice of collar heights
of 1mm, 2mm and 2.4mm. The 1mm and 2mm collar height abutments are straight
and the 2.4mm collar height abutment has a 15 degree angle machined in relation
to the flat side of the hex. Number markings indicate the emergence profile and
a single black line indicates the 3.0 implant/abutment connection group.
Emergence profiles
Straight 3.5/4.0 TiDesign™ abutments are available with a choice of three
emergence profiles (4.5, 5.5, 6.5mm) and a collar height of 1.5mm or 3mm
for each emergence profile. Two angled abutments with a angulation of 20
degrees and a collar height of 3mm with a choice of two (4.5, 5.5mm) emergence
profiles are also offered. Number markings indicate the emergence profile and
a double black line indicates the 3.5/4.0 implant/abutment connection group.
Collar height
4.5/5.0 connection diameter TiDesign™ abutments are machined with
two (5.5, 6.5mm) emergence profiles and either a 1.5mm or 3mm collar. One
20 degree angled abutment with a emergence profile of 5.5mm and a collar
height of 3.5mm is also available. Number markings indicate the emergence
profile and the absence of a black line indicates the 4.5/5.0 implant/abutment
connection group.
Collar height
Direct Abutment API™ titanium abutments are conceptually designed
for posterior restorations and intended to be installed by the surgeon.
These abutments are machined as a one piece unit (abutment body and screw)
without a index (hex) at the implant/abutment connection interface.
Intended for abutment level impressions with
appropriate plastic impression
copings.
3.5/4.0 platform group direct abutments are available with a 4mm
emergence profile and a choice of four (0.5, 1, 2.5, 4mm) collar heights or
a emergence profile of 5mm and three (1, 2.5, 4mm) possible collar heights.
4.5/5.0 platform group direct abutments are available with a 5mm
emergence profile and a choice of four (0.5, 1, 2.5, 4mm) collar heights or
a emergence profile of 6mm and three (1, 2.5, 4mm) possible collar heights.
Emergence profile
All abutments are marked with a black line 1mm from the top of the abutment
in case the abutment needs intraoral height adjustment. Analogs are marked
in the same manner and can then be reduced to the same height, using the
marker as a reference point. A number printed on the abutment indicates the
emergence profile (4, 5 or 6mm). These abutments are usually sold as a
kit
containing the abutment, abutment carrier, impression coping, analog and
burnout copings but also available a la carte. Abutments are torqued to
25Ncm regardless of platform connection diameter group.
Collar height
ZirDesign™ abutments are made through and through in zirconia,
machined in a similar geometry as TiDesign™ abutments. The 3.5/4.0
platform group is offered with a choice of two (1.5, 3mm) collar heights
and two (4.5, 5.5mm) emergence profiles for either collar height. A pre
angled abutment with a 20 degree angle, 5.5 emergence profile and
Emergence profile
collar height of 3.5mm is part of the zirconia abutment product line.
The 4.5/5.0 platform group is also offered with a choice of two (1.5, 3mm)
collar heights and two (5.5, 6.5mm) emergence profiles for either collar
height. A pre angled abutment with a 20 degree angle, 5.5 emergence profile
and collar height of 3.5mm is part of the zirconia abutment product offering.
A final screw is included with each abutment as a kit.
UCLA
CastDesign™ abutments are UCLA's made with a hexed,
machined gold implant/abutment connection interface and a plastic cylinder
pressed on to the gold portion of the abutment. Each platform group
(3.5/4.0, 4.5/5.0) has its own geometry and made to fit only their
respective platform group. A final screw is included with each abutment as
a kit. Stock, non indexed UCLA's are not available for Astra Tech implants.
TempDesign™
TempDesign™ abutments for each implant/abutment
connection interface group (3.5/4.0, 4.5/5.0) are manufactured with a
titanium base and a plastic cylinder pressed on to the titanium base.
Abutments are available with and without indexing feature (hex).
Through and through temporary titanium with and without indexing feature
(hex) are also offered. A final screw is included with each abutment as a
kit. The manufacturers recommended torque setting is 15 Ncm regardless
of platform connection diameter group.
UniAbutments serve as intermediary abutments for splinted, screw
reatained restorations and substructures. Theses abutments may be utilized
in situations with exessive tissue height (≥2mm) above implants or to
correct a unfavorable final screw access path. Special UCLA abutments
(discussed below) or CAD CAM substructures are required for UniAbutments.
UniAbutment straight
Straight UniAbutments are non indexed and machined as a mono block,
integrating the screw and abutment in to a single entity, either with a
20 degree or 45 degree cone to achive a common path of draw for the final
restoration. The correction of draw may be up to 40 and 90 degrees
respectively. Both platform diameter (3.5/4.0 aqua, 4.5/5.0 lilac)
UniAbutments are not color coded for platform identification and
available in six collar heights of 0.5, 1, 2, 4, 6 and 8mm. A special
UniAbutment driver is required to torque (20Ncm) the abutments in place.
UniAbutment angled
Angled UniAbutments for 3.5/4.0 and 4.5/5.0 platform implants are
machined with a 20 degree angle as a two component set (screw and abutment).
Offered as indexed and non indexed versions with a collar height of 0.8mm
and 2mm. The abutments have a height of 5.1mm plus the collar height,
making the stack height of the components (UniAbutment plus UCLA or CAD
substructure) considerable. No color coding or other markings are present
on the abutments for platform diameter identification.
UniAbutment UCLA's
UniAbutment UCLA components are machined to fit the type of UniAbutment
(straight 20°, straight 45°, angled) regarless of platform diameter (3.5/4.0,
4.5/5.0). UCLA's are made with a non hexed, machined gold, plastic or
titanium implant/abutment connection interface. Gold and titanium interfaces
are press fit with a plastic cylinder on to the metal portion
of the abutment. A final screw is included with each abutment as a kit and
torqued to 15Ncm.
OsseoSpeed™ Profile
Profile TiDesign™
Profile TiDesign™ abutments are manufactured with a hex for indexing
and are packaged as a kit with a final screw. Straight 4.5/5.0 TiDesign™
abutments are available with a choice of two emergence profiles (5.5, 6.5mm)
and a collar height of 1.8mm or 3mm for each emergence profile. One 15
degree angled abutment with a emergence profile of 6.2mm and a collar
height of 2.7mm is also available. Number markings indicate the emergence
profile and a "P" indicates the Profile 4.5/5.0 implant/abutment connection
group.
Profile Temporary
abutment
One straight engaging temporary abutment is currently available for the
Profile implant product line. The abutment has a 1.5mm sloping collar
and the lowest point of the slope synchronized with the flat side of the
indexing feature (hex). A total height of 9mm and a emergence profile of
5.3mm. The final screw is included with each abutment as a kit.
