Astra Tech IMPRESSION COPINGS

OsseoSpeed™

Indirect copings

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).

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.
