Intended Use

AB Dental CAD/CAM Base Abutments and Adhesive Sleeves are dental prosthetics placed onto a dental implant or screw retained abutment, to provide support for dental prosthetic restorations. The Base Abutments and Adhesive Sleeves include: Titanium bases/sleeves with a pre-machined implant connection or screw retained abutment connection on which the CAD/CAM designed upper structure may be fitted to complete a two-piece dental abutment. The Base Abutments and Adhesive Sleeves include an abutment/sleeve screw for fixation to the underlying implant/screw retained abutment. These dental prosthetics may be used for single-tooth or multiple-unit (bridges and bars) restorations and are compatible for use with AB Dental Implants with internal connection and screw retained connections for standard and narrow platforms. All digitally designed abutments and/or copings for use with AB Dental CAD/CAM Base Abutments and Adhesive Sleeves are intended to be sent to AB Dental validated milling center for manufacture.

Device Story

Device consists of titanium alloy (Ti-6Al-4V ELI) base abutments and adhesive sleeves used as part of a two-piece dental abutment system. Inputs include patient intra-oral scan data used to design a custom CAD/CAM zirconia superstructure. The titanium base/sleeve is fixed to the implant or screw-retained abutment via a screw; the CAD/CAM superstructure is then cemented to the titanium base using dental cement. Used in dental clinics by dentists/prosthodontists. Design and manufacturing occur at a validated milling center. Output is a final prosthetic restoration providing support for single or multiple-unit teeth. Benefits include patient-specific fit and restoration of dental function.

Clinical Evidence

No clinical data were included in this submission. Evidence consists of bench testing, including fatigue testing per ISO 14801, cytotoxicity testing per ISO 10993-5, and MRI safety testing per ASTM F2052, F2213, F2182, and F2119.

Technological Characteristics

Materials: Ti-6Al-4V ELI titanium alloy. Components: Anti-rotational and rotational base abutments, adhesive sleeves. Connectivity: CAD/CAM digital workflow requiring validated milling center. Sterilization: End-user sterilized. MR Conditional per ASTM F2503-20.

Indications for Use

Indicated for patients requiring single-tooth or multiple-unit (bridges and bars) dental prosthetic restorations supported by dental implants or screw-retained abutments.

Regulatory Classification

The indications for the subject device and the indications cleared in K181580 are provided above.

The difference between the subject device and the predicate is that the highlighted sections were removed as this submission doesn't include the Titanium abutment blanks.

In addition, in the predicate devices the description of the Ti-Base refers also to screw retained sleeves (they refer to them as abutment or 2-component abutment).

The language was also adjusted to match AB Dental products throughout the text.

The sleeves are intended to be used with devices that are angled at 0°, 17°, and 30°. No additional angulation provided by these sleeves or the CAD/CAM ceramic restorations.

The purpose of this traditional 510(k) is to expand the current product line to include the new abutments listed below. No substantive changes are being made to the indications. Comparison tables for each modification are provided below.
