After the implant has been placed, the art of communicating the proper implant position and tissue profile to our laboratory should not be taken for granted. In order to communicate this position, an accurate digital or analog impression must be taken of the implant position. If the impression post is not seated properly, an inaccurate abutment/screw-retained restoration will be fabricated.
Straumann has dedicated resources to assure this critical step is as straightforward as possible for the restorative dentist as well as for the patient. With Straumann’s unique CrossFit design, the clinician can sense through tactile feedback if the impression post or scanbody is properly seated. Furthermore, the screw will only tighten if it is seated properly, so the stress of a mis-seated impression component is greatly reduced.
This innovation prevents the patient from needing a verification radiograph and streamlines the workflow. In addition, the 4.1 mm and 4.8 mm bone level implants utilize the same impression post and scanbody, minimizing the inventory one must keep on hand, and reduces unnecessary confusion on which parts must be ordered.
When Straumann implants are used with genuine Straumann abutments, the CrossFit design provides further stability by providing an orthogonal fit between implant and abutment. This feature helps prevent rotation. While the Straumann bone-level implant provides stability, it also provides flexibility. The deep 15° internal conical connection allows for a stable implant abutment connection while offering flexibility on splinted restorations.
In a perfect world, parallel positioned implants are ideal, but clinical issues may prevent this from happening. Implants with up to 30° of divergence can be successfully restored with Straumann’s prosthetic offerings.
Congratulations to Straumann for continuing to refine their offering; it is very comforting to see developments happen both in terms of biologic success and predictability of usage.
