Device Description
CEREC Cercon 4D™ CAD/CAM Block are pre-sintered zirconia blocks composed of yttria stabilized zirconia, which are designed for CAD/CAM milling. The proposed CEREC Cercon 4D™ CAD/CAM Blocks possess a 3-dimensional contour of dentine powder to mimic the natural tooth build-up. The aim of the 3D contour technology is to achieve more aesthetic restorations than with blocks based on the current multi-layer technology. The CEREC Cercon 4D™ CAD/CAM Blocks are used for fabrication of a dental restoration. The CEREC Cercon 4D™ CAD/CAM Blocks are not provided as the finished, fully finished dental restoration. The blocks are single use, meaning that they can only be milled once and are not recommended for re-milling. The blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM milling and subsequent sintering to fabricate all ceramic restorations and they are not intended to be reused as in the context of direct patient-applied devices and materials. Therefore, no reprocessing, cleaning or disinfection instructions apply because it is a dental material and not a finished dental restoration itself. After sintering of the restoration, the dental professional will finish the restoration via polishing or glazing, before insertion into the patient's mouth.
More Information

No
The summary describes a material block for CAD/CAM milling and does not mention any software or algorithms that would incorporate AI/ML.

No
The device, CEREC Cercon 4D™ CAD/CAM Blocks, is a material used to fabricate dental restorations (crowns, bridges, inlays, onlays, veneers). It is an intermediate product that requires further processing (milling, sintering, polishing, glazing) by dental professionals before it becomes a finished device that is inserted into a patient's mouth. Therefore, it is a material used in the creation of therapeutic devices, but not a therapeutic device itself.

No

The device description clearly states that these are pre-sintered zirconia blocks for CAD/CAM milling, designed for the fabrication of dental restorations (crowns, bridges, inlays, onlays, veneers). They are materials to be further processed, not a tool for diagnosis.

No

The device description clearly states it is a pre-sintered zirconia block, which is a physical material used for milling dental restorations. It is not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for fabricating dental restorations (crowns, bridges, inlays, onlays, veneers) for placement in a patient's mouth. This is a therapeutic and restorative purpose, not a diagnostic one.
  • Device Description: The device is a material (zirconia block) used to create a finished dental restoration. It is not used to test a sample from the human body to provide information about a physiological state, health, or disease.
  • Lack of Diagnostic Function: There is no mention of the device being used to analyze biological samples, detect markers, or provide any diagnostic information.
  • Performance Studies: The performance studies focus on the material's physical properties, biocompatibility, and suitability for creating dental restorations, not on diagnostic accuracy or performance.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnostic purposes. This device is a material used to create a medical device (a dental restoration) that is placed in vivo (inside the body).

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 (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.

4. Description of Device:

CEREC Cercon 4D™ CAD/CAM Block are pre-sintered zirconia blocks composed of yttria stabilized zirconia, which are designed for CAD/CAM milling. The proposed CEREC Cercon 4D™ CAD/CAM Blocks possess a 3-dimensional contour of dentine powder to mimic the natural tooth build-up. The aim of the 3D contour technology is to achieve more aesthetic restorations than with blocks based on the current multi-layer technology.

5

The CEREC Cercon 4D™ CAD/CAM Blocks are used for fabrication of a dental restoration. The CEREC Cercon 4D™ CAD/CAM Blocks are not provided as the finished, fully finished dental restoration. The blocks are single use, meaning that they can only be milled once and are not recommended for re-milling. The blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM milling and subsequent sintering to fabricate all ceramic restorations and they are not intended to be reused as in the context of direct patient-applied devices and materials. Therefore, no reprocessing, cleaning or disinfection instructions apply because it is a dental material and not a finished dental restoration itself. After sintering of the restoration, the dental professional will finish the restoration via polishing or glazing, before insertion into the patient's mouth.

5. Indications for Use:

Indications for CEREC Cercon 4D™ CAD/CAM Blocks are:

  • · Crowns and bridges in the posterior and anterior tooth region.
  • · Bridges with a maximum of two pontics
  • · Inlays, onlay and veneers

The reference devices, CEREC Cercon 4D™ Abutment Block, CEREC Cercon 4D™ Abutment System (K234018) and Cercon (K162888) are included to support the composition of the block material. The composition of the proposed device is similar to the composition of the reference devices, CEREC Cercon 4D™ Abutment Block, CEREC Cercon 4D™ Abutment System (K234018) and Cercon (K162888). The main difference in composition is the yttrium oxide ranges due to the 3-dimensional contour of dentine powder to mimic the natural tooth build-up which achieves a more aesthetic restorations based on the multi-layer technology. The proposed and reference devices both contain pigments for shading esthetics.
