Intended Use
CEREC Cercon 4D™ Abutment System is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations. The system comprises three parts: CEREC Cercon 4D™ Abutment Block, TiBase, CAD/CAM system. The CEREC Cercon 4D™ ceramic structure cemented to the TiBase is recommended for two-piece hybrid abutments for single tooth restorations and hybrid abutment crowns, used in conjunction with endosseous dental implants.
Device Story
Device consists of Yttria-doped zirconia blocks used to fabricate ceramic structures for two-piece hybrid abutments (mesostructure and crown). Blocks feature pre-drilled screw access channels and anti-rotation features. Used with TiBase (titanium base) and CAD/CAM system. Operated by dental professionals in clinical or lab settings. CAD/CAM software designs the restoration; user selects TiBase, which defines gingival height and post height. Final ceramic structure is cemented to TiBase. System ensures structural integrity for single-tooth restorations. Benefits include patient-specific aesthetic and functional restoration of edentulous sites.
Clinical Evidence
No clinical data included. Substantial equivalence supported by bench testing, including flexural strength (ISO 6872:2015) and fatigue testing (ISO 14801:2016) on worst-case combinations of angulation, platform size, and gingival height.
Technological Characteristics
Yttria-doped zirconia blocks. Designed for CAD/CAM milling. Non-sterile. Requires steam sterilization post-assembly. Meets ISO 6872 (flexural strength >1,100 MPa) and ISO 14801 (fatigue). Biocompatible per ISO 10993.
Indications for Use
Indicated for partially or fully edentulous patients requiring single cement-retained restorations supported by endosseous dental implants. Compatible with various Dentsply Sirona, BioHorizons, Nobel Biocare, Straumann, Thommen Medical, Osstem/Hiossen, Zimmer/Biomet, MIS, and Altatec Camlog implant systems.
Regulatory Classification
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.

Dear Rebecca Sporer:
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).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

## 4. Description of Device:
The CEREC Cercon 4D Abutment Blocks, which are used for fabrication of a ceramic structure, two-piece hybrid abutments (meso-structure and crown) and abutment crowns, that are cemented to a TiBase (titanium base) used with dental implant systems. The CEREC Cercon 4D Abutment Blocks are not provided as the finished, fully assembled dental implant medical devices. The abutment blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM technology and they are not intended to be reused as in the context of direct patient-applied devices and materials.
CEREC Cercon 4D™ Abutment Block are Yttria-doped zirconia blocks suitable for chairside and lab side use in fabrication of single cement-retained restorations. CEREC Ceron 4D™ Abutment Block are designed with a pre-drilled screw access channel and anti-rotation feature. The design allows for fabrication of a ceramic structure, two-piece hybrid abutments (mesostructure and crown) and abutment crowns, that are cemented to the TiBase (Titanium base) used with dental implant systems. The following patient-specific ranges for CAD/CAM fabrication of the subject abutments are:
- . Maximum angulation of 200
- . Minimal wall thickness of 0.5 mm
- Gingival height ranges from 0.3-2.0 mm ●
- Minimum abutment post height (i.e. length above the gingival height) of ≥ 4 mm .
{9}------------------------------------------------
- 5. Indications for Use:
CEREC Cercon 4D™ Abutment System is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations.
The system comprises three parts:
- CEREC Cercon 4D™ Abutment Block

The indications for use of the proposed device do not constitute a new intended use. The proposed CEREC Cercon 4D™ Abutment Block has the same intended use and similar indications for use compared to the predicate, CEREC Tessera Abutment Block, CEREC Tessera Abutment System (K221402) and reference device Sirona Dental CAD/CAM System (inCoris ZI meso material) (K111421) in that they are used with TiBases, Implant Systems and CAD/CAM technology. The main difference is the compatible Implant systems and titanium bases. The block material and TiBase make up an a 2-piece hybrid abutment which is used in conjunction with endosseous dental implants to restore the function and aesthetics in the oral cavity. Table 6.2 compare the Intended Use and Indications for Use when compared to the predicate and reference devices.
