More Information

No
The summary describes a material (thermoplastic acrylic disc) used in CAD/CAM technology for dental prostheses. There is no mention of AI or ML in the device description, intended use, or performance studies. The focus is on the material properties and mechanical performance.

No
This device is a material (thermoplastic acrylic disc) used to manufacture dental prostheses and restorations, which are considered medical devices, but the disc itself is not directly therapeutic.

No

The device description clearly states that G-CAM discs are "suitable for the creation of dental prostheses" and are "intended to be used for the manufacture of full and partial removable dentures as well as permanent and temporary restorations." This indicates it is a manufacturing material for medical devices, not a device used for diagnosis.

No

The device description clearly states that G-CAM is a thermoplastic acrylic disc made of PMMA resin doped with graphene, which is a physical material used for manufacturing dental prostheses. The performance studies also focus on mechanical and biocompatibility testing of this material.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the G-CAM discs are used for the manufacture of dental prostheses (dentures, crowns, bridges, etc.). This is a manufacturing process for a medical device that will be placed in the body.
  • Device Description: The description reinforces that it's a material (thermoplastic acrylic disc) used for creating dental prostheses.
  • Lack of Diagnostic Function: There is no mention of the device being used to diagnose a condition, analyze a sample from the human body, or provide information about a patient's health status. IVDs are used in vitro (outside the body) to examine specimens like blood, urine, or tissue to detect diseases, conditions, or infections.
  • Performance Studies: The performance studies focus on the material's mechanical properties, biocompatibility, and strength, which are relevant to its use as a dental restorative material, not as a diagnostic tool.

The G-CAM disc is a material used in the creation of a medical device (dental prostheses), but it is not a diagnostic device itself.

The logo consists of the word "Graphenano" in a dark gray, sans-serif font, with the word "DENTAL" in a light blue, sans-serif font underneath. To the right of the text is a light blue hexagon with a white tooth icon inside. The logo is clean and modern, and the color scheme is professional and calming.

The previous indications for G-CAM are supported by the following concepts:

  • & G-CAM, polymethyl methacrylate (PMMA) doped with Graphene, is manufactured using the heat-curing method.
  • & G-CAM presents high modulus and elastic limit to ensure that the tensions generated during biting and chewing do not cause permanent deformations, and it is possible to manufacture prosthesis of smaller sections.
  • & G-CAM presents high deformation resistance and stress limit, thus avoiding the formation of cracks and fractures.
    • G-CAM is low density making the prosthesis lightweight.
  • & G-CAM increases the material hardness comparing with acrylic resins used in dentistry.
  • & G-CAM final appearance is similar to oral tissue. Thus ideal for visible areas.
  • ❖ G-CAM has colour stability.
    • G-CAM has wide chromatic range, even within the same piece, making it look extremely natural.
    • G-CAM disc is chemically inert.
  • ❖ G-CAM water absorption is 4 µg/mm3 and a solubility of 0.5 µg/mm2. The release of residual monomer is minimum, with a percentage of 0.004% of residual monomer. Thanks to these physical properties G-CAM offers a durable and safety treatment.

G-CAM is available in different formats, thicknesses, colors and anchors, having all the variations the same physicochemical characteristics.

DEVICE DESING DESCRIPTION

The device is presented in a disc form which allow to process the dental prostheses with specific CAD /CAM equipment.

G-CAM disc is available in 2 different formats: G-CAM MONOCHROMA and G-CAM MULTICHROMA. Monochrome and Multichroma discs may be both used for anatomical monolithic restorations.

When machined, G-CAM Monochroma and G-CAM Multichroma present a different visual effect:

Image /page/5/Picture/0 description: The image shows the logo for Graphenano Dental. The word "Graphenano" is written in a dark gray sans-serif font. Below it, the word "DENTAL" is written in a light blue sans-serif font. To the right of the text is a light blue hexagon with a white tooth inside.

  • G-CAM Monochroma, is made of one pure VITA Classic guide's colour. .
  • . G-CAM Multichroma, it has a chromatic spectrum based in natural colour imitating the optical effects of the natural pieces.

The more suitable choice between monochrome and multichrome disc will depend on the final application given to the device.

G-CAM is presented as a compacted resin disc offered in two different anchor dimensions.

There are two different discs variants base on the specified type of anchor used by the CAM device:

Universal anchorage: disc of 98.5mm diameter

Zirkonzahn anchorage: disc of 95mm diameter

Both variants are presented in different thicknesses: 14,16, 18, 20, 22, 24, 26, 28 and 30.

G-CAM device is available in the following colours TRANSPARENT, A1, A2, A3, A3.5, B1, B2, BL1, BL2, C2 and PINK (according to VITA classic guide).

G-CAM discs are provided non-sterile and as a single use device.

G-CAM must be used only by professionals as dental lab technicians and / or dentist.

G-CAM should be stored at room temperature in its original packaging, in dry storage and avoid exposure to direct sunlight. PMMA polymer from which the G-CAM disc is made is stable and can be stored for an extended period of time having a calculated 5-year shelf life (real-time testing method).

V. INTENDED USE / INDICATIONS FOR USE (21 CFR 807.92(a)(5))

As established in the Indications for Use Statement:

"G-CAM discs are intended to be used for the manufacture of full and partial removable dentures, implant overdentures as well as permanent and temporary restorations such as anterior or posterior crowns and bridges, inlays, onlays, veneers, copings and substructures."

The primary predicate device, Juvora dental disc, and G-CAM, are classified under the same product codes: EBF - Material, Tooth Shade, Resin; EBG - Crown and Bridge Temporary Resin; EBI -Denture Relining, Repairing, Rebasing Resin. As can be seen in Table.1, below, the intended use of G-CAM and the Juvora dental disc is equivalent. Specifically, one indication of G-CAM is that is intended for final crowns and bridges, inlays, onlays and veneers restorations which means that can be used as a direct monolithic solution with no need of using other materials to make aesthetics restorations. Juvora dental disc is intended for frameworks used on such restorations being possible the necessity of some other materials to make is more aesthetic.

The reference device, CAD/CAMouflage Milling Block, has a same intended use that one of the G-CAM intended use but more restricted. The CAD/CAMouflage Milling Block physical presentation is different as is presented as a block with smaller width dimensions than the disc. Its usefulness is intended for small parts so that is only classified as EBF- Material, Tooth Shade, Resin and EBG -Crown and Bridge Temporary Resin.

The differences with G-CAM and those two predicate devices do not affect the safety and effectiveness of the device when used as labeled.

VI. SUMMARY OF THE TECHNOLOGICAL CHARACTERISTICS OF THE PROPOSED DEVICE AND THE PREDICATE DEVICES (21 CFR 807.92(a)(6))

Image /page/7/Picture/0 description: The image shows the logo for Graphenano Dental. The word "Graphenano" is in a dark gray sans-serif font, with the word "DENTAL" in a smaller, light blue sans-serif font underneath. To the right of the text is a light blue hexagon with a white tooth inside. The logo is clean and modern, and the colors are calming and professional.

Graphenano Dental has used the FDA's Guidance for Industry and FDA Staff – "Dental Composite Resin Devices - Premarket Notification [510(k)] Submissions'' for comparing its G-CAM with the Primary Device, JUVORA Dental Disc, and Reference device, CAD/CAMouflage Milling Block. Both are legally marketed devices under 21 CFR 807.92(a)(3) classified as Class II. The technological characteristics comparison table (Table 1) outline and provides the difference, similarities and the substantial equivalency of G-CAM and the cited predicate and reference devices.

SUMMARY OF SUBSTANTIAL EQUIVALENCE DISCUSSION:

Most of the G-CAM technological characteristics are substantially equivalent to the predicate device JUVORA Dental Disc. Both are thermoplastic materials, available in disc format and designed to be processed with a CAD/CAM system. The main difference is that they are composed of different raw materials. Both devices have been evaluated under the applicable standards for their intended use and they achieve the required values established by those.

When compared to the primary and reference predicate devices, the intended use and technological characteristics of G-CAM doesn't raise new issues related to safety and effectiveness. Based on the information provided in this submission, G-CAM is substantially equivalent to the primary predicate and reference devices.

The differences on physical properties and chemical compositions between G-CAM and the predicate devices do not impact safety and effectiveness. The finished product is biocompatible regardless of the material variation.

In general, we consider the proposed device to be substantially equivalent to the predicate device and consider that any differences between the proposed and reference devices will not pose new concern.

G-CAM therefore could be used as a
direct monolithic solution which
means that it does no need using other
materials to make aesthetic
restorations while the primary
predicate disc would normally need
other material to show a more
aesthetic solution. |
