Product details & FAQ

Castable abutments let the laboratory create a fully customized abutment shape in the material of its choice. This page collects every castable option for the Alef internal-hex implant in one place: standard castable abutments, castable abutments with shoulder, angled castable abutments with shoulder, castable abutments on a titanium base, and castable abutments on a chrome-cobalt base.

Standard castable abutments

The standard castable abutment (Ø3.75 mm, 10.5 mm high) comes in a non-rotational version (CANR), with an anti-rotation hex, for single units, and a rotational version (CAR) for splinted work and bridges.

Castable abutments with shoulder

The non-rotational castable abutment with shoulder (CANR1–CANR3) is offered with collar heights of 1, 2 and 3 mm, so the margin can be positioned according to soft-tissue depth. Angled versions of 15° (CA15NR1–CA15NR3) and 25° (CA25NR1–CA25NR3) are available for cases that need axis correction.

Castable abutments with a titanium or chrome-cobalt base

The castable abutment with titanium base (CATB, Ø4.5 mm, 10.5 mm high) provides a machined titanium connection with a castable upper part. The chrome-cobalt base versions (CCR rotational, CCNR non-rotational, Ø4.0 mm, 11 mm high) give a cast-on option with a CoCr interface. The type of base determines the connection quality, so choose the version your laboratory workflow requires.

How to choose

First decide whether the restoration is single-unit (non-rotational) or splinted (rotational). Then decide whether you need a shoulder and collar height, an angled version, or a titanium/CoCr base. Select the type and version above; the reference code is shown for each combination. The torque values are maximum recommendations and should not replace the clinician’s judgment.

Frequently asked questions

What is the difference between rotational and non-rotational?

Non-rotational abutments have an anti-rotation hex and suit single units; rotational abutments have no hex and suit splinted restorations and bridges.
