## Indications for Use

FlexiBase® titanium bases for Axiom® BL are intended to support screw-retained restorations on Axiom® BL dental implants.

## Device Story

Anthogyr FlexiBase® titanium bases are two-piece dental abutments for Axiom® BL implants; used to support single-unit customized prosthetic restorations. Device consists of a titanium alloy base, a prosthetic screw (DLC-coated titanium alloy), and a patient-specific coping/crown. Clinicians design restorations using Straumann CARES® Visual software; digital designs are sent to a validated Straumann milling center for fabrication. The titanium base is screwed into the implant; the coping/crown is cemented onto the base using dental cement (e.g., PANAVIA V5). The final assembly is screwed into the patient's implant. Used in dental clinics by dentists/prosthodontists. Benefits include customized prosthetic support for single-tooth replacement. Device is provided non-sterile; requires end-user steam sterilization.

## Clinical Evidence

No clinical data. Evidence consists of bench testing, including dynamic fatigue testing (ISO 14801) in saline at 37°C for 2 million cycles (permanent) and 200,000 cycles (temporary) without failure. Biocompatibility was evaluated per ISO 10993-1 and ISO 10993-5. Sterilization was validated per ISO 17665-1/2.

## Technological Characteristics

Materials: Titanium alloy (3.7165.1-Ti-6Al-4VELI). Dimensions: 4.0mm/5.0mm platform diameters; 1.5mm/2.5mm/3.5mm gingival heights. Energy: Mechanical (screw-retained). Connectivity: Digital workflow via Straumann CARES System. Sterilization: Non-sterile, requires autoclave. Software: CAD/CAM design software.

## Regulatory Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

## Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)

#### Dear Jennifer Jackson:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

#### Device Description

#### Anthogyr FlexiBase® titanium bases for Axiom® BL

Anthogyr FlexiBase® titanium bases for Axiom® BL are intended to be placed into Anthogyr dental implants to provide support for single-unit restorations. The second component of the two-piece abutment (coping or crown) must be cemented onto the titanium component of the FlexiBase® abutment to constitute the final two-piece abutment design, which is then screwed onto the implant.

The bottom portion of the FlexiBase® are made from Titanium alloy. They are provided in several dimensions, there is one chimney height, and two platform diameters of 4.0 mm and 5.0 mm, and for each of the platform diameters there are three gingival heights of 1.5 mm, 2.5 mm and 3.5 mm.

Anthogyr FlexiBase® titanium bases for Axiom® BL are very similar to the primary predicate device Medentika TiBase CAD/CAM Abutments cleared in K150203.

The FlexiBase® are fixed in the implant by means of a prosthetic screw which is manufactured in titanium alloy and DLC coated identical to K161177.

{6}------------------------------------------------

### K231072 - Anthogyr FlexiBase® titanium bases for Axiom® BL

The FlexiBase® abutments are two-piece abutments used as a base when fabricating a CAD/CAM customized restoration. The design and milling of the customized restoration must be made using the Straumann CARES® Visual software.

The FlexiBase® is a two-piece abutment ultimately composed by three components:

- . FlexiBase® abutment titanium component
- Top-half component (coping and/or crown) .
- . Prosthetic screw

The FlexiBase® abutments will be marketed:

- through a validated Straumann Centralized milling center, in this case all digitally . designed copings and/or crowns are intended to be manufactured at a validated Straumann milling center (Straumann CARES® System).
#### Prosthetic Restoration Design and Materials

The following is an overview of the possible coping materials:

- n!ce CoCr .
- n!ce Zr LT
- . n!ce Zr HT
- . n!ce Zr XT
- . n!ce glass ceramic
- . n!ce PMMA (temporary)

The design of the digital coping and/or crown should follow the standard procedure according to the material manufacturer's instructions for use and Anthogyr's instructions for use.

#### Anthogyr prosthetic screw

A prosthetic screw is used to fix abutments to dental implants. The screw is provided with the abutments and also available standalone (replacement).

The prosthetic screws are manufactured from titanium alloy and are DLC coated identical to K161177.

#### Intended Use

FlexiBase® titanium bases for Axiom® BL are intended to support screw-retained restorations on Axiom® BL dental implants.
