G-CAM discs are intended to be used for the manufacture of full and partial removable dentures as well as permanent and temporary restorations such as anterior or posterior crowns and bridges, inlays, veneers, copings and substructures.
G-CAM is a thermoplastic acrylic disc made by a principal base of polymethyl methacrylate (PMMA) resin doped with graphene (allotropic form of carbon), suitable for the creation of dental prostheses using CAD/CAM technology.
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 provided text describes a 510(k) premarket notification for a dental device called G-CAM. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving novel clinical effectiveness through extensive human studies. Therefore, the information regarding "acceptance criteria" and "study that proves the device meets the acceptance criteria" will largely relate to non-clinical performance testing against recognized standards and comparison with predicate devices, as clinical human-in-the-loop studies were explicitly not performed.
Here's a breakdown of the requested information based on the provided document:
Acceptance Criteria and Device Performance for G-CAM
The acceptance criteria for G-CAM are primarily based on demonstrating substantial equivalence to predicate devices through conformity with recognized international standards for dental materials.
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly present a "table of acceptance criteria" in a traditional sense with numerical targets before the results. Instead, it provides a comparison table (Table 1) that lists the G-CAM's characteristics and its measured performance against the relevant ISO standards, alongside the characteristics of the predicate devices. The "acceptance" is implied by meeting or exceeding the minimum requirements of the specified ISO standards, and by showing substantial equivalence to the predicate devices.
Table.1 Comparison of G-CAM with Predicate and Reference Devices (with performance data)
| Feature | Acceptance Criteria (from ISO Standard) | Reported G-CAM Performance | Predicate (JUVORA Dental Disc) Performance (where stated) | Reference (CAD/CAMouflage Milling Block) Performance (where stated) |

| Flexural Strength | ISO20795 > 65 MPa; ISO10477 ≥ 50 MPa | 140 MPa +/-7% (ISO 20795); 148 MPa (ISO 10477) | 165 MPa (ISO 20795); 192 MPa (ISO 10477) | Not stated |
| Surface Hardness | Not specified directly, but comparable to predicates | 88 ShoreD (ISO 48-4); 19.5 KHN (ASTM E384) | Not stated | Not stated |
| Water Absorption | ISO20795 < 32 µg/mm³; ISO10477 < 40 µg/mm³ | 4 µg/mm³ (ISO 20795) | Not stated | < 7.5 µg/mm³ (ISO 10477) |
| Residual Monomer | ISO20795 < 2.2% | <0.004% (ISO 20795) | Not stated | Not stated |
| Water Solubility | ISO20795 < 1.6 µg/mm³; ISO10477 < 7.5 µg/mm³ | <0.5 µg/mm³ (ISO 20795) | Not stated | Not stated |
| Compressive Strength | Not specified directly, but comparable to predicates | Not stated in this section (but mentioned for predicate as 156 MPa (ISO 5833)) | 156 MPa (ISO 5833) | Not stated |
| Filler Particle Size | Not specified directly, but comparable to predicates (mentioned for reference device) | 21.5 µ (ISO 13320) | Not stated | Not stated |

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: The document does not explicitly state the number of physical samples (e.g., discs, test specimens) used for each specific non-clinical test (e.g., flexural strength, water absorption). The testing was performed according to recognized standards (e.g., ISO 20795-1, ISO 10477), which would dictate the appropriate sample sizes for each test.
- Data Provenance: The tests were conducted by Graphenano Dental S.L. in Spain. The data is from non-clinical bench testing. The document does not specify if the testing was retrospective or prospective in terms of a specific study design as it's a premarket submission focusing on material properties.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- This question is not applicable in the context of this 510(k) submission. The "ground truth" for material properties is established by the specifications and methodologies of the international ISO standards themselves, not by human expert consensus or interpretation of images. The tests measure physical and chemical properties directly.
- The tests were performed by laboratories or personnel competent in conducting tests according to the specified ISO standards for dental materials.
4. Adjudication Method for the Test Set
- Not applicable. This concept typically applies to clinical studies where subjective human assessments (e.g., image interpretation) need to be resolved. For objective bench testing of material properties, results are quantitative and do not require adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No, an MRMC comparative effectiveness study was not done. The document explicitly states: "Clinical testing is not required to demonstrate substantial equivalence as the indications for use are like legally marketed devices and the designs previously cleared under a premarket notification." and "No clinical studies are submitted."
- Therefore, there is no effect size of how much human readers improve with AI vs. without AI assistance, as this is a dental material and not an AI-assisted diagnostic device.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
- Not applicable. This device is a dental material (G-CAM discs) intended for the manufacture of dental prostheses using CAD/CAM technology. It is not an algorithm or an AI-based system. Its performance relates to its material properties and manufacturing quality, not autonomous algorithmic outputs.
7. Type of Ground Truth Used for Performance Testing
- Non-clinical material properties: The "ground truth" or reference for the performance testing of the G-CAM device are the specifications and minimum requirements outlined in recognized international standards such as ISO 20795-1 (Dentistry — Base polymers — Part 1: Denture base polymers), ISO 10477 (Dentistry — Polymer-based crown and veneering materials), ISO 4049 (Dentistry — Polymer-based restorative materials), ISO 48-4 (Plastics — Determination of hardness — Part 4: Durometer method), ASTM E384 (Standard Test Method for Knoop and Vickers Hardness of Materials), ISO 13320 (Particle size analysis — Laser diffraction methods), ISO 7405 (Dentistry — Evaluation of biocompatibility of medical devices used in dentistry), and ISO 10993 (Biological evaluation of medical devices).
- For biocompatibility, specific tests (Cytotoxicity, Sensitization, Acute Systemic Toxicity, Subchronic Toxicity by Subcutaneous Implantation, Material-Mediated Pyrogenicity, Genotoxicity, Carcinogenicity) were performed to establish the ground truth of biological safety.
8. Sample Size for the Training Set
- Not applicable. This device is a physical dental material, not an AI or machine learning model that requires a "training set" of data.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. As stated above, there is no training set for this type of medical device submission.

Image /page/4/Picture/0 description: The image contains the logo for Graphenano Dental. 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:
{5}------------------------------------------------
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).
{6}------------------------------------------------
Image /page/6/Picture/0 description: The image shows the logo for Graphenano Dental. The word "Graphenano" is written in a bold, dark gray font. Below it, the word "DENTAL" is written in a smaller, light blue font. To the right of the text is a light blue hexagon with a white tooth inside.
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))
{7}------------------------------------------------
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.

IDENTIFICATION OF THE RISK ANALYSIS METHOD
G-CAM has conducted a preliminary hazard analysis which identify risks, including risk of mechanical failure, toxicity and adverse tissue reaction, improper use, and incompatibility with other dental devices. The Failure Modes Effect Analysis (FMEA) showed that all risks, when reduced as far as possible, were acceptable. There were no so severe risks found to cause severe damage or that lead to the death of a patient. The device mechanical properties are comparable to predicate devices. The biocompatibility testing showed that G-CAM is biocompatible. The labeling of the device is designed to reduce the risk of improper use.
DISCUSSION OF THE DEVICE CHARACTERISTICS
To reduce the risk of mechanical failure, G-CAM was designed according to applicable standard to its intended use. In addition, each production is subjected to an exhaustive quality control to check that the product is in accordance with its technical specifications. Also, to reduce the risk of mechanical failure cause of milling errors, specific information is qiven to the professional clients in documents like Instructions for Use, Work process, Design Parameters Sheet and Labelling, Moreover, G-CAM is a thermoplastic solid material, so additional curing steps are not needed which prevents improper fabrication due to varying curing or working times.
To reduce the risk of toxicity and adverse tissue reaction, G-CAM was tested against biocompatibility standards as specified by ISO 7405:2008, Dentistry - Evaluation of biocompatibility of medical devices used in dentistry. Moreover, G-CAM labeling is designed to reduce the risk of improper use.
DESCRIPTION OF THE PERFORMANCE ASPECTS (21 CFR 807.92 (b)(1)(2))
The testing of the performance aspects was performed to recognized standards, such as ISO 20795-1 and ISO 10477. (see Table 1 for specific application knowledge). There are no deviations to the procedure of the standard for the tests performed.

The logo features the word "Graphenano" in a dark brown, sans-serif font, with the word "DENTAL" in a smaller, teal font below it. To the right of the text is a teal hexagon with a white tooth icon inside. The logo is clean and modern, suggesting a dental company that utilizes advanced materials or technology.
SUMMARY DISCUSSION OF NON-CLINICAL DATA:
The subject device has been subject to bench to determine conformance to performance specifications and requirements taking account of its intended use and following all recommendations set out in FDA Document "Dental Composite Resin Devices-Premarket Notification [510(k)] Submissions".
Non-clinical testing performed in foreseeable operating conditions showed correct operation of the device as per its intended use and specifically included mechanical performance.
Clinical testing is not required to demonstrate substantial equivalence as the indications for use are like legally marketed devices and the designs previously cleared under a premarket notification.
RELIANCE OF STANDARDS
The G-CAM product has demonstrated conformance with the non-clinical performance requirements through evaluation and testing in accordance with the following standards:
· Chemical and physical testing having under considerations ISO 4049; ISO 20795-1 and ISO 10477 (Compression, Elastic modulus, Bending strength, Water absorption and Residual monomer, radiopaque...)
· Biocompatibility check for G-CAM material composition per ISO 7405 where the use of ISO 10993 is specified. Results for Cytotoxicity, Sensitization, Acute Systemic Toxicity, Subchronic Toxicity by Subcutaneous Implantation, Material-Mediated Pyrogenicity, Genotoxicity and Carcinogenicity concluded that the device is biocompatible.
The results of this non-clinical testing show that the strength of the G-CAM product is sufficient for its intended use and is substantially equivalent to the legally marketed predicate device.
