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.
