Device Story

Surefil one™ is a self-adhesive dental restorative material used for direct restorations and core build-ups. It utilizes a resin-modified glass ionomer chemistry provided in a powder/liquid formulation within a mixing capsule. The device is applied by dental professionals in a clinical setting. It features a triple-cure mechanism (light-curing, self-curing, and acid-base reaction) to harden the material. The device provides self-adhesiveness to enamel and dentin, fluoride release, and radiopacity. By eliminating the need for separate etching and adhesive steps, it simplifies the restorative workflow, potentially reducing procedure time and improving clinical efficiency for the practitioner while providing a durable filling material for the patient.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including compressive strength, flexural strength, setting time, radiopacity, shear bond strength (enamel, dentin, composite), enamel wear, and ACTA wear testing, conducted per ISO 9917-2:2017. Biocompatibility and chemical analysis of leachables were performed per EN ISO 10993-1.

Technological Characteristics

Resin-modified glass ionomer chemistry; powder/liquid formulation in mixing capsule; triple-cure (light, self, acid-base); radiopaque (2mm aluminum equivalent); fluoride releasing; non-sterile; storage 2°C-24°C. Tested per ISO 9917-2:2017.

Indications for Use

Indicated for dental patients requiring Class I to Class V restorations or core build-up procedures.

Regulatory Classification

Identification

Zinc oxide-eugenol is a device composed of zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp. Dental cement other than zinc oxide-eugenol is a device composed of various materials other than zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp.

Dear Karl Nittinger:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

### 7. Non-Clinical Performance Data:

In-vitro bench tests were performed on the Surefil one™ Self-adhesive Composite Hybrid according to the requirements in ISO 9917-2:2017 (Dentistry -Water based cements - part 2: Resin-modified cements) and internal Dentsply Sirona criteria.

Bench tests included in support of substantial equivalence of Surefil one™ Selfadhesive Composite Hybrid. Compartative tests were performed between the proposed Surefil one™ Self-adhesive Composite Hybrid and the predicate device (K130223). A summary list of testing conducted in support of substantial equivalence is as follows:

- Compressive strength ●
- Flexural strength ●
- Setting time
- Radio-opacity ●
- Shear bond strength to enamel ●
- Shear bond strength to dentin
- Shear bond strength to composite ●
- Enamel wear ●
- . ACTA (Academic Center for Dentistry Amsterdam) wear test

The performance of the Surefil one™ Self-adhesive Composite Hybrid satisfactorily met the requirements of the non-clinical bench testing conducted to support substantial equivalence.

Cytotoxicity testing was performed for Surefil one™ Self-adhesive Composite Hybrid as well as chemical analysis of leachable organic and inorganic compounds in compliance with the standard EN ISO 10993-1. The results of the biocompatibility testing and chemical analysis conducted relating to the subject Surefil one™ Self-adhesive Composite Hybrid support its substantial equivalence.

#### 8. Clinical Performance Data

No data from human clinical studies has been included to support the substantial equivalence of the Surefil one™ Self-adhesive Composite Hybrid.

#### 9. Conclusion Regarding Substantial Equivalence

The Surefil one™ Self-adhesive Composite Hybrid has the same intended use and has similar indications for use as the primary predicate Pulpdent RMGI FILL (K130223) and the secondary predicate GC Fuji Direct (K172382). Test data to verify the performance of the Surefil one™ Self-adhesive Composite Hybrid has been provided including: compressive and flexural strength, adhesion to enamel, dentin and composite, setting time, ACTA (Academic Center for Dentistry Amsterdam) wear, enamel wear and radio-opacity and the results of this testing, combined with the design and intended use comparison with the primary predicate device, support substantial equivalence.
