Astra Tech IMPRESSION COPINGS

OsseoSpeed™

Astra started to color code actual components in 2010 to facilitate easier identification in regards to platform diameters. Below both identification systems are described as "old style" and "new style".

Indirect copings

Old style
Fixture level impression copings for the indirect (closed tray) impression technique for each implant/abutment connection platform (3.0, 3.5/4.0, 4.5/5.0) group are machined in a symmetrical triangular fashion in relation to their indexing feature, making the repositioning in to the impression effortless because any position as long as the flat sides of the impression coping line up with the flat sides in the impression is correct. No tools are required to screw the impression coping on to the implant or analog.
Only one impression coping for the 3.0 platform is offered and can be identified through the platform number printed on to the impression coping body. 3.5/4.0 and 4.5/5.0 platform diameter group impression copings are available in two lengths (16, 19mm). 3.5/4.0 platform group impression copings can be identified through the platform group numbers "3.5/4.0" printed on to the coping body. The 4.5/5.0 platform group impression coping is only marked with the numbers "4.5", even though a 5.0 implant can also be impressed with this impression coping. The latest versions of the impression copings are color coded according to the platform group diameter (3.0 yellow, 3.5/4.0 aqua, 4.5/5.0 lilac).

Direct indexed

Fixture level impression copings for the direct (open tray) impression technique are rendered with and without indexing feature for the 3.5/4.0 and 4.5/5.0 platform groups only. Use of non indexed impression copings should only occur after careful consideration because if the restoration design needs to be changed due to unforeseen circumstances after impression taking a second impression procedure with indexed impression copings may be necessary.

Direct non indexed

Both platform group direct impression copings are available in four (21, 26, 22, 27mm) lengths depending on the platform group. Indexed copings are marked with their respective platform group numbers on the top edge of the impression coping body. Non indexed impression copings are marked with two slots at the top edge of the impression coping for the 3.5/4.0 platform and three slots for the 4.5/5.0 platform. The latest versions of the impression copings are color coded according to the platform group diameter (3.0 yellow, 3.5/4.0 aqua, 4.5/5.0 lilac).

Only one impression coping for the 3.0 platform is offered and can be identified through the yellow coloring. 3.5/4.0 and 4.5/5.0 platform diameter group impression copings are available in two lengths (16, 19mm). 3.5/4.0 platform group impression copings can be identified through the aqua coloring. The 4.5/5.0 platform group impression copings are identified through lilac coloring .

Use of non indexed impression copings should only occur after careful consideration because if the restoration design needs to be changed due to unforeseen circumstances after impression taking a second impression procedure with indexed impression copings may be necessary.

Direct non indexed

Both platform group direct impression copings are available in four (21, 26, 22, 27mm) lengths depending on the platform group. Indexed copings and non indexed impression copings are marked with two slots at the top edge of the impression coping for the 3.5/4.0 platform and three slots for the 4.5/5.0 platform. 3.5/4.0 components are color coded aqua and 4.5/5.0 platform copings are color coded lilac.

Plastic copings

Abutment level impressions over Direct API™ abutments are carried out with emergence profile specific plastic copings. Color coding of the copings is carried out in regards to the emergence profile of the abutment and not in relation to the platform diameter group. The plastic copings engage the flat side of the abutment and snap over the abutment. A raised nub on top of the impression coping indicates where the flat side inside the coping is located. Number "4" direct abutments are impressed with a white coping, number "5" direct abutments are impressed with a gray coping and number "6" direct abutments utilize a blue coping.

UniAbutment
UniAbutments for 3.5/4.0 and 4.5/5.0 platform diameter implants are produced with a 20 degree or 45 degree cone and as a 20 degree angled abutment for screw retained restorations. Impression copings for UniAbutments are not platform diameter dependent but chosen in regards to the degree of the cone or 20 degree angled abutment type.

Indirect copings

Indirect, closed tray abutment level impression copings are machined as a monoblock combining the fixation screw and the impression coping body in to a singular entity. These copings are universally utilized for both cone (20 and 45 degree) UniAbutments. Making it mandatory to note on the Rx for the laboratory technician which degree cone is actually installed on the implant.

Direct copings

Direct, open tray 20 and 45 degree cone abutment level impression copings are machined as a two component unit, the fixation screw and the impression coping body. 20 degree and 45 degree impression copings are specifically designed for either 20 or 45 degree UniAbutments. Although neither impression coping is marked for degree type identification. Both 20 and 40 degree impression copings are offered in two emergence profiles of 4.3 and 5.5mm.

20 degree angled abutment impression copings are only available as a direct impression impression coping.

Locator® & ball

Locator®
Installed Locator® abutments are impressed with standard snap on Locator® impression copings.

Ball abutment
Ball abutments are impressed with blue plastic snap on impression copings. The ball dimension and female attachment portion are designed after the Preci-Clix attachment from Preat Corp and 100% compatible.

OsseoSpeed™ Profile

Indirect indexed

Fixture level impression copings for the indirect (closed tray) impression technique for Profile implants are machined in a asymmetrical fashion in relation to the indexing feature. The flat side of the impression coping needs to be aligned with the lowest part of the implant slope at the time of impression taking. This feature makes the repositioning in to the impression effortless because only one position, as long as the flat side of the impression coping lines up with the flat side in the impression is correct. No tools are required to screw the impression coping on to the implant or analog. Two indirect impression copings are offered, short and long.

Direct indexed

Fixture level impression copings for the direct (open tray) impression technique are rendered with engaging indexing feature for the Profile implants. The impression coping body is machined with a channel to be aligned with the lowest part of the implant slope at the time of impression taking. Two direct impression copings are offered, short and long.
