FiltekTM Supreme Flowable Restorative is a low viscosity, visible-light activated, radiopaque, flowable nanocomposite. It is available in a variety of tooth-colored shades. Filtek™ Supreme Flowable Restorative contains Bis GMA, TEGDMA, and Procrylat K resins. The fillers are a combination of an Ytterbium Fluoride filler, a non-agglomerated/non-aggregated surface-modified silica filler, and a surface-modified aggregated zirconia/silica cluster filler. The aggregate has an average cluster particle size of 0.6 to 10 microns. The inorganic filler loading is approximately 65% by weight (46% by volume). Filtek Supreme Flowable Restorative is applied to the tooth following the use of a methacrylate-based dental adhesive such as manufactured by 3M, which permanently bonds the restoration to the tooth structure. When irradiated by light, the methacrylate functionalities of the resin and fillers undergo, in conjunction with the photoinitiator system, a light-induced polymerization to form a hard composite that is bonded to the tooth structure with a permanent dental adhesive. The product is available in both syringe and capsule delivery systems.

AI/ML Overview

This document describes the 3M™ Filtek™ Supreme Flowable Restorative, a dental material, and its substantial equivalence to predicate devices, focusing on the expansion of its indications for use. As this is a 510(k) submission for a physical medical device (dental restorative material) and not a software or AI-driven device, the detailed questions about acceptance criteria, study design for AI algorithms, expert ground truth, adjudication methods, MRMC studies, standalone performance, and training set details are not directly applicable in the context of this document.

However, I can extract and present the information available regarding the device's performance based on the provided text, interpreting the "acceptance criteria" as the regulatory and standard requirements it needed to meet for its expanded indications, and the "study" as the in vitro testing performed.

2. Sample Size Used for the Test Set and Data Provenance:

Sample Size for Test Set: Not explicitly stated as a number of individual samples. However, the text indicates "Testing was undertaken to substantiate the use of the Filtek Supreme Flowable Restorative for Classes I, II, and IV restorations". This implies multiple samples were tested for each physical property to satisfy the requirements of the listed ISO standards. The specific number of specimens for each test (e.g., flexural strength, compressive strength) would be defined by those ISO standards.
Data Provenance: The testing was "in vitro testing" conducted with the existing flowable restorative material (Filtek™ Supreme Ultra Flowable Restorative, which is identical to the applicant device in formulation) in an updated syringe delivery device. The location of the testing or the origin of the raw materials for testing are not specified beyond the company's location (3M Company ESPE Dental Products, St. Paul, MN, USA). It is a retrospective study in the sense that it relies on the formulation of an existing, cleared device.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications:

This question is not applicable. The "ground truth" for this type of device is established through adherence to recognized international standards (ISO) and FDA guidance for material properties. There are no "experts" in the sense of clinicians or radiologists establishing a diagnostic ground truth for individual cases. The standards themselves define the acceptable ranges and methodologies.

4. Adjudication Method for the Test Set:

This question is not applicable. Adjudication methods like 2+1 or 3+1 typically refer to human expert consensus for diagnostic or grading tasks in clinical studies where individual expert opinions might vary. For material property testing, the results are quantitative measurements interpreted against pre-defined thresholds or compared statistically against predicate devices or standards. There is no human "adjudication" in this context.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance:

This question is not applicable. The device is a dental restorative material, not an AI-driven diagnostic or treatment assistance tool. Therefore, no MRMC study involving human readers with or without AI assistance was conducted or is relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

This question is not applicable. The device is a physical dental material, not an algorithm.

7. The Type of Ground Truth Used:

The "ground truth" for this device is based on:

International Standards: ISO 4049:2019 (Dentistry - Polymer-based Restorative Materials) and ISO 6874:2015 (Dentistry - Polymer-based pit and fissure sealants).
FDA Guidance: "Dental Composite Resin Devices – Premarket Notification [510(K)] " issued on October 26, 2005.
Predicate Device Performance: Comparison to the performance of the primary predicate (3M™ ESPE™ Filtek™ Supreme Ultra Flowable Restorative) and the secondary predicate (Tetric EvoCeram). The "truth" is that the applicant device's performance must meet or exceed the performance of these established devices and regulatory limits for the intended use.

8. The Sample Size for the Training Set:

This question is not applicable. There is no "training set" in the context of a physical dental material and its performance testing. Deep learning or machine learning models require training sets, but this is not an AI or software device.

9. How the Ground Truth for the Training Set Was Established:

This question is not applicable, as there is no training set for this type of device.

{5}------------------------------------------------

Description of Device:

FiltekTM Supreme Flowable Restorative is a low viscosity, visible-light activated, radiopaque, flowable nanocomposite. It is available in a variety of tooth-colored shades.

Filtek™ Supreme Flowable Restorative contains Bis GMA, TEGDMA, and Procrylat K resins. The fillers are a combination of an Ytterbium Fluoride filler, a nonagglomerated/non-aggregated surface-modified silica filler, and a surface-modified aggregated zirconia/silica cluster filler. The aggregate has an average cluster particle size of 0.6 to 10 microns. The inorganic filler loading is approximately 65% by weight (46% by volume).

Filtek Supreme Flowable Restorative is applied to the tooth following the use of a methacrylate-based dental adhesive such as manufactured by 3M, which permanently bonds the restoration to the tooth structure. When irradiated by light, the methacrylate functionalities of the resin and fillers undergo, in conjunction with the photoinitiator system, a light-induced polymerization to form a hard composite that is bonded to the tooth structure with a permanent dental adhesive. The product is available in both syringe and capsule delivery systems.

Indications for Use:

Direct Restoration of all cavity classes (I-V) ●
Base/liner under direct restorations ●
. Repair of small defects in esthetic indirect restorations
Repair of resin and acrylic temporary materials ●
Pit and fissure sealant ●

The purpose of this submission is to update the Indications for Use for this product to include all cavity classes of direct restorations and to summarize other changes that did not require 510(k) submission, such as a minimal change to the syringe design and extension of shelf-life to 36 months.

Technological Characteristics:

Filtek™ Supreme Flowable Restorative is identical to the primary predicate Filtek™ Supreme Ultra Flowable Restorative (K10023) in terms of formulation, design, performance features, and biocompatibility as well as manufacturing processes. The change in the name of the product is for simplification purposes only.

{6}------------------------------------------------

Substantial equivalence

As the primary goal of this submission is to update the Indications for Use to include all cavity classes, the information provided in this 510(k) submission shows that the product is substantially equivalent to the primary predicate, 3M Filtek Supreme Ultra Flowable Restorative (K100235), and the secondary predicate, Tetric EvoCeram (K042819), a device that has been cleared for all cavity classifications.

Indications forUse	• Direct restoration of allcavity classes (I-V)• Base/liner under directrestorations• Repair of small defects inesthetic indirect restorations•Repair of resin and acrylictemporary materials• Pit and fissure sealant	• Class III and V restorations• Restoration of minimallyinvasive cavity preparations(including small,non-stress-bearing occlusalrestorations)• Base/liner under directrestorations• Repair of small defects inesthetic indirect restorations•Repair of resin and acrylictemporary materials• Pit and fissure sealant• Undercut blockout	• Anterior Restoration (ClassIII, IV)• Class V restorations (cervicalcaries, root erosion, wedge-shaped defects)•Restoration of the posteriorregions (Class I and II)•Veneering of discoloredanterior teeth• Splinting of mobile teeth• Repair of composite andceramic veneers

No new questions of safety and effectiveness are raised with these additional Indications for Use. The changes to the Indications for Use as compared to the primary predicate are explained below. The decision to remove these indications is based on a desire to simplify the Indications for Use.

"Restoration of minimally invasive cavity preparation" is considered a smaller subset of Class I-V restorations and does not require a separate indication for use.

"Undercut blockout" is a procedure used for both direct and indirect restoration. It is considered a part of tooth prepping for any class of direct restoration.

The decision not to add additional information to each class of restoration (unlike the secondary predicate device) was based on the well-understood definition of the classes of restorations, which is part of the dentist's training.

{7}------------------------------------------------

The difference between the shades offered by the secondary predicate and Filtek Supreme Flowable Restorative does not affect the functionality of Filtek Supreme Flowable restorative; it can be used safely and effectively for all the proposed indications.

The safety and efficacy of 3M Filtek Supreme Flowable Restorative remain unchanged from the primary predicate, Filtek Supreme Ultra Flowable Restorative, since Filtek Filtek Supreme Flowable Restorative is identical to the primary predicate device in terms of formulation, design, performance features, and biocompatibility as well as manufacturing processes.

The additional minor changes (including updated delivery tip design and addition of the narrower gage tip) do not affect the safety and efficacy of the product.

Testing was undertaken to substantiate the use of the Filtek Supreme Flowable Restorative for Classes I, II, and IV restorations, the new indication being added when compared to the secondary predicate device. This 510(k) submission includes data from in vitro testing per FDA Guidance "Dental Composite Resin Devices – Premarket Notification [510(K)] " issued on October 26, 2005, ISO 4049:2019 Dentistry -Polymer-based Restorative Materials, and ISO 6874:2015 Dentistry - Polymer-based pit and fissure sealants. To evaluate the performance of Filtek Supreme Flowable Restorative for these new indications, comparative testing results for the following physical properties were included in this submission:

Flexural Strength -
Compressive Strength -
Surface hardness (Barcol) -
Elastic Modulus/Flexural Modulus -
Radiopacity -
Water Sorption -
Water Solubility -
Fracture toughness to demonstrate chip resistance -

This testing was conducted with the existing flowable restorative material (Filtek Supreme Ultra Flowable Restorative), the primary predicate device) in an updated syringe delivery device. The results submitted in the 510(k) demonstrated material strength equivalent or superior as compared to the secondary predicate. All results met the requirements of the ISO standards 4049 and 6874. In particular, the acceptability of the test results in comparison with the secondary predicate establishes the adequacy of Filtek Supreme Flowable Restorative to be used in all classes of cavity restorations.

The biocompatibility of the applicant device product was also assessed, and it was confirmed that no additional biocompatibility testing was required to support the submission because the formulation of Filtek Supreme Flowable Restorative is identical to the primary predicate device since the clearance of its original 510(k) and continues to meet biocompatibility requirements.

Nanotechnology assessment and risk evaluation of the formulation in Filtek Supreme Flowable Restorative and Filtek Supreme Ultra Flowable Restorative did not identify any specific health hazards attributable to the nanomaterials present in the product.

Based on stability studies, the established shelf life for Filtek Supreme Flowable restorative is 36 months at ambient temperature. The stated shelf-life is predictive of both syringe and capsule shelf-life stability.

Conclusion:

The conclusions drawn from the nonclinical tests demonstrate that the proposed subject device is as safe, as effective, and performs as well as the legally marketed predicate devices.
