Exatec-S - Active root posts made of Titanium with a special shaped self-tapping thread.
Active root posts made of Titanium with a special shaped self-tapping thread.The anchoring is made with maximum 3 rotations without putting strain to the dentine and with a torque of only 7,9 +/– 1,7 Ncm*) that is comparatively low.
*) determined in a comparative dissertation in 1994
Optimized stability of reconstruction
The conical apical part can be designed longer than a cylindrical shape and has an exceptionally
small end. Due to these advantages the conical Exatec posts can be inserted deeply into the root canal.
- 4 cement escape grooves
- large post cross-section (> 3 mm²) and rounded juncture provide high strength
- self-tapping thread
- rounded tip
Explore the details
A root post with a tapered apical part offers many advantages over a cylindrical post:
Due to the tapered shape, which corresponds to the natural contour of the tooth root, more tooth substance is preserved in the critical area of the root tip, thus minimizing the risk of root fractures.
At the transition from post to head, which is prone to breakage, the tapered Exatec post has rounded transitions and a larger post cross-section compared to a cylindrical post of the same apical length. The Exatec post thus has higher stability and achieves higher values in bending load tests.
The Exatec calibration drill prepares a precisely fitting axial support for the Exatec post head, which inherently determines the position where the post has dentin contact without exerting pressure on the root wall, as the downward movement of the post is precisely stopped at the axial support.
The precise support ensures the axial support of the post head in the dentine and stops precisely the movement of post to the apical direction.
The Exatec Calibration Drill with integrated head cutter calibrates a precise support.
