Alef Ti-Base Abutment

Product details & FAQ

A Ti-base is the titanium interface on which a milled or pressed crown or abutment is bonded. It joins the digital workflow to the Alef implant connection: the laboratory designs and mills the upper part, and the Ti-base provides a precise, titanium-to-titanium connection to the implant. This page covers the standard Alef Ti-bases and the Sirona-compatible Ti-bases in rotational and non-rotational versions.

Standard Ti-base abutments

Standard Ti-bases (Ø4.5 mm) come in a non-rotational version (TBNR05, TBNR15, TBNR25), with an anti-rotation hex, for single crowns, and a rotational version (TBR00, TBR05, TBR15, TBR25, TBR35, TBR45) for splinted or bridge work. The collar height, from 0 mm to 4.5 mm, sets the level of the bonding surface relative to the soft tissue.

Sirona-compatible Ti-base abutments

The Sirona-compatible Ti-bases (Ø4.3 mm) are offered in rotational (STBR05, STBR15, STBR30) and non-rotational (STBNR05, STBNR15, STBNR30) versions, with collar heights of 0.5, 1.5 and 3.0 mm, for laboratories working in that design environment.

How to choose

Decide first whether the restoration is single-unit (non-rotational) or splinted (rotational), then select the collar height according to the soft-tissue depth. Select the type, rotation and collar above; the reference code is shown for each combination. Torque values are maximum recommendations and should not replace the clinician’s judgment. For a scan body to capture the implant position, see the Alef scan body.
