Device Description

ESTELITE BULK FILL Flow is a low viscosity, light cured radiopaque composite dental tooth shade resin material. This low stress flowable material can be placed in 4 mm increments. The device incorporates Radical-Amplified Photopolymerization (RAP) initiator technology, which facilitates a shortened light curing time and ample working time. The device comes in five shades, namely U (Universal), A1, A2, A3, and B1.

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description and performance studies focus on the physical and chemical properties of a dental resin material, with no mention of AI or ML.

Therapeutic

No.
The device is a restorative material used to fill cavities and restore teeth, which is not considered a therapeutic function. It does not treat or cure a disease or condition.

Diagnostic

No
The device, ESTELITE BULK FILL Flow, is described as a tooth shade resin material used in dental procedures for restorations and cavity lining. Its intended use focuses on treatment and repair, not on identifying a disease or condition.

SaMD (Software as a Medical Device)

No

The device description clearly states it is a "low viscosity, light cured radiopaque composite dental tooth shade resin material," which is a physical substance, not software.

IVD (In Vitro Diagnostic)

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

Here's why:

• Intended Use: The intended use is for direct dental procedures on teeth, such as restorations, cavity lining, and repairs. This involves direct application to the patient's body.
• Device Description: The device is a dental resin material applied directly to the tooth.
• Lack of In Vitro Testing: While there is non-clinical testing of physical properties, there is no mention of testing biological samples (blood, urine, tissue, etc.) outside of the body to diagnose or monitor a medical condition.
• Anatomical Site: The anatomical site is the tooth, which is part of the patient's body.

IVD devices are used to examine specimens derived from the human body in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device is applied in vivo (within the body) for therapeutic and restorative purposes.

Other similar reference devices are ESTELITE FLOW QUICK High Flow (also cleared under K#051808), FILTEK BULK FILL FLOWABLE RESTORATIVE (K#120453), and the nuance FLOW tooth shade resin material (K#143679). As shown above, the K#051808 and K#120453 devices demonstrate that certain characteristics of the subject device that are not included in the ISO 4049:2009 recognized standard but that are included in the FDA's 2005 guidance on Dental Composite Resin Devices are within the norm of similar legally marketed devices. Furthermore, K#120453 is cleared for use as a "liner under direct restorative materials," which is essentially the same as the "cavity liner" indication for Tokuyama's ESTELITE BULK FILL Flow tooth shade resin subject device.

A further chart comparing Tokuyama's ESTELITE BULK FILL Flow tooth shade resin subject device with the ESTELITE FLOW QUICK primary predicate K#051808 and the reference devices K#120453 and K#143679 appears on the following two pages.

For purposes of biocompatibility, the ESTELITE BULK FILL Flow device is substantially equivalent to Tokuyama's own TOKUYAMA BOND FORCE (K#070215), ESTELITE FLOW OUICK (K#051808), and ESTELITE COLOR (K#110178), as all ingredients in the ESTELITE BULK FILL Flow device have been cleared for marketing by the FDA for use in these similar devices.

Device Description

ESTELITE BULK FILL Flow is a low viscosity, light cured radiopaque composite dental tooth shade resin material. This low stress flowable material can be placed in 4 mm increments. The device incorporates Radical-Amplified Photopolymerization (RAP) initiator technology, which facilitates a shortened light curing time and ample working time. The device comes in five shades, namely U (Universal), A1, A2, A3, and B1.

Biocompatibility testing is not required because all the ingredients in the ESTELITE BULK FILL Flow device have already been authorized by the FDA for use in similar devices and Tokuyama Dental Corporation has received almost no complaints of personal adverse effects of any kind (and no serious injury) involving the ingredients used in the ESTELITE BULK FILL Flow device.

The device does not come sterilized and is not intended to be sterilized prior to use.

Indications for Use

The ESTELITE BULK FILL Flow device is indicated for use as a tooth shade resin material in dental procedures, such as:

• Direct anterior and posterior restorations
• Cavity lining
• Blocking out cavity undercuts before fabricating indirect restorations
• Repair of porcelain/composite

Comparison of Technological Characteristics

The ESTELITE BULK FILL Flow device has the same basic technological characteristics in terms of design, material, and chemical composition as the predicate device identified above, as each device is a tooth shade resin material that is cured by photo polymerization. The ESTELITE BULK FILL Flow device does not have its own energy source.

8

For purposes of material and chemical composition, the ESTELITE BULK FILL Flow device has the same basic characteristics as Tokuyama's own Tokuyama's own TOKUYAMA BOND FORCE (K#070215), ESTELITE FLOW QUICK (K#051808), and Estelite Color (K#110178).

Performance Data Summary

Non-clinical testing of the physical properties of the ESTELITE BULK FILL Flow device was conducted in accordance with ISO 4049:2009. There were no clinical tests performed for the ESTELITE BULK FILL Flow device.

The device does come into direct contact with the patient. All of the ingredients in the ESTELITE BULK FILL Flow device have been authorized by the FDA for use in similar Tokuyama devices. Thus, under Section 6 of ISO 10993-1, no further biocompatibility testing is required.

The ingredients in the ESTELITE BULK FILL Flow device are the same as in three of Tokuvama's own previously authorized devices, namely TOKUYAMA BOND FORCE (K#070215), ESTELITE FLOW QUICK (K#051808), and ESTELITE COLOR (K#110178). These devices have been used for many years without any reportable incidents to local health authorities and for which almost no complaints have been received regarding personal adverse effects of any kind and no serious injuries.

Conclusion

Based on the non-clinical testing conducted of the physical properties of the ESTELITE BULK FILL Flow device in comparison to the predicate devices identified above, and on the biocompatibility of authorized devices for the same use with the same ingredients, it is concluded that the ESTELITE BULK FILL Flow device is substantially equivalent to the predicate devices.
