- Direct anterior veneers
- Anterior Class III and IV restorations
- Class V restorations (cervical caries, root erosion, wedge-shaped defects)
- Closing of diastemas
- Repair of composite and ceramic veneers
- Top layer of Class I and II restorations
Renamel® Microfill is light-cured, microfilled, highly polishable dental restorative material. According to the applicable FDA recognized consensus standard ISO 4049 - "Dentistry -Polymer-based restorative materials", this device is classified as Type 1, Class 2, Group 1: Polymer-based restorative materials, involving occlusal surfaces, which uses external energy source for intra-orally curing. Renamel® Microfill consists of multi-functional acrylic Resin and fillers of 0.04 - 0.2 micron sized particles of inorganic and prepolymerized composite (70% by weight, 60% by volume). These devices possess physical and mechanical properties that allow them to function in the oral cavity with esthetic quality that mimics natural enamel surface.
This document describes the premarket notification for the Renamel® Microfill dental restorative material. The acceptance criteria and supporting study details are primarily focused on the physical and mechanical properties of the material, demonstrating its substantial equivalence to a predicate device.
1. Acceptance Criteria and Reported Device Performance:
Property / Standard | Specification (Acceptance Criteria) | Renamel® Microfill Performance (Reported Device Performance) |
---|---|---|
Depth of cure (other than opaque materials) ISO 4049:2009; Type1, Class2, Group1 | ≥ 1.5mm | 2.15 mm ± 0.1mm |
Flexural strength ISO 4049:2009; Type1, Class2, Group1 | ≥ 80 MPa | 95.5 MPa ± 3 MPa |
Water sorption ISO 4049:2009; Type1, Class2, Group1 | ≤ 40 µg/mm³ | 15 µg/mm³ ± 0.5 µg/mm³ |
Solubility ISO 4049:2009; Type1, Class2, Group1 | ≤ 7.5 µg/mm³ | 0.9 µg/mm³ |
Radiopacity ISO 4049:2009; Type1, Class2, Group1 | ≥ 1mm (Not claimed by applicant) | None (not claimed) |
Compressive strength | ≥ 320 MPa | 410 MPa ± 40 MPa |
Modulus of elasticity | ≥ 3000 MPa | 5100 MPa ± 300 MPa |
2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the sample size used for each specific test (e.g., number of specimens for depth of cure, flexural strength, etc.). However, it does refer to the ISO 4049:2009 standard for testing polymer-based restorative materials, which would inherently dictate the sample sizes required for statistically sound testing. The data provenance is not specified, but it can be inferred that these are in-house laboratory tests conducted by Cosmedent, Inc. or a contracted testing facility to comply with the referenced ISO standard. The data is retrospective in the context of this submission, meaning the tests were performed before the submission to demonstrate compliance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This information is not applicable to this document. The "ground truth" for the performance criteria of a dental restorative material is established through objective, standardized physical and mechanical property testing according to international standards (ISO 4049). It does not involve expert consensus in the same way clinical diagnostic studies might.
4. Adjudication Method for the Test Set:
This information is not applicable to this document. Adjudication methods like 2+1 or 3+1 are typically used in studies where human interpretation of data (e.g., medical images) is involved and discrepancies need to be resolved. For material property testing, the results are typically quantitative measurements.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
This information is not applicable to this document. MRMC studies are relevant to diagnostic devices involving human interpretation of medical data, often with AI assistance. This document pertains to a dental restorative material, which is not a diagnostic device and does not involve "human readers" in the context of interpretation.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This information is not applicable to this document. This refers to the performance of an AI algorithm independently. The Renamel® Microfill is a physical dental material, not an AI algorithm.
7. The Type of Ground Truth Used:
The ground truth used for demonstrating compliance is based on objective, quantitative measurements of physical and mechanical properties derived from standardized laboratory tests as defined by ISO 4049:2009 and other general material testing standards (e.g., for compressive strength and modulus of elasticity). This is equivalent to established scientific and engineering standards for material performance.
8. The Sample Size for the Training Set:
This information is not applicable to this document. "Training set" refers to data used to train machine learning models. The Renamel® Microfill is a physical product, and its development and testing do not involve machine learning training in this context.
9. How the Ground Truth for the Training Set was Established:
This information is not applicable for the same reason as point 8.

Resin Tooth Bonding Agent is used to facilitate the adhesive bonding of restorative/preventive dental materials to dental hard tissues as well as to other restorative materials.
Cosmedent Resin Tooth Bonding Agent is a dual-cure 4th generation resin tooth bonding agent based on an acetone solution of room temperature polymerizing dimethacrylates. The device consists of two bottles designated as Primer A and Primer B. Primer A can be used alone and light cured, or it can be mixed with Primer B whereupon the adhesive will self cure in a clinically appropriate amount of time. In either case, two coats of the adhesive are applied to the prepared teeth. The adhesive bond strength of the device is approximately 25 MPa. The product is intended to be used to promote the adhesion of resin composite restoratives to dentin and enamel.
This device, Cosmedent Resin Tooth Bonding Agent, is a dual-cure 4th generation resin tooth bonding agent. The provided text indicates it's a 510(k) submission, meaning the manufacturer is demonstrating that their new device is substantially equivalent to a legally marketed predicate device. This type of submission relies on comparison to a predicate device rather than extensive new clinical trials to establish safety and effectiveness. Therefore, the information typically found in a clinical study report proving acceptance criteria is not present in this document.
However, based on the provided text, we can infer some "acceptance criteria" through the comparison made to the predicate device, Bisco All-Bond 2 (K910860). The primary performance metric mentioned for both the applicant and predicate device is adhesive bond strength.
Here's the breakdown of the information requested, based on the available text:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Inferred from Predicate) | Reported Device Performance (Applicant Device) |
---|---|
Adhesive bond strength of approximately 28 MPa (Predicate: Bisco All-Bond 2) | Adhesive bond strength of approximately 25 MPa |
Note: The "acceptance criteria" here are inferred from the performance of the legally marketed predicate device. For a 510(k), substantial equivalence implies that the new device's performance should be comparable to or not worse than the predicate's performance in clinically relevant aspects.
2. Sample size used for the test set and the data provenance
The document does not detail specific sample sizes for testing or data provenance for the reported bond strength values. 510(k) submissions often rely on bench testing and comparisons to predicate devices, rather than large-scale clinical trials. The reported bond strength values (25 MPa and 28 MPa) would typically come from in-vitro (bench) testing.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. The document does not describe the establishment of a "ground truth" using experts for the reported bond strength. These values are typically derived from standardized material testing in a laboratory setting.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable. The document does not describe an adjudication method as no expert-based review or clinical trial is detailed for the bond strength measurements.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a dental bonding agent, a physical material, and does not involve AI or human "readers." Therefore, an MRMC study is not relevant.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a dental bonding agent, not a software algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
