Intended Use

Ceraclean is an extraoral cleaner of pre-treated ceramic, zirconia and metal restoration surfaces which have been contaminated during intraoral try-in.

Device Story

CeraClean is an extraoral cleaning gel used by dental professionals to remove saliva contamination from prosthetic restorations (ceramic, zirconia, metal) after intraoral try-in. The device is applied to the restoration surface via syringe tip or brush, then rinsed off with water prior to final cementation or priming. Unlike abrasive cleaners, CeraClean is a non-abrasive, water-based gel containing potassium hydroxide. It functions by chemically cleaning the substrate; the gel is fully water-soluble and leaves a neutral pH surface after rinsing. By effectively removing contaminants, the device ensures optimal bonding conditions for the final placement of the restoration, potentially improving clinical outcomes and restoration longevity.

Clinical Evidence

Bench testing only. Evaluated shear bond strength using modified ISO 29022:2013, water solubility, and pH levels. SEM EDX analysis confirmed complete removal of the cleaning agent from the substrate. Biocompatibility testing performed per ISO 7405:2008 and ISO 10993-1:2009, including cytotoxicity testing, demonstrated compliance with requirements.

Technological Characteristics

Water-based gel; active ingredient: potassium hydroxide; viscosity modifier: xanthum gum; pigmented (blue). Non-abrasive; water-soluble. Applied via syringe or brush. Neutral pH after rinsing. Biocompatibility tested per ISO 7405:2008 and ISO 10993-1:2009.

Indications for Use

Indicated for cleaning pre-treated ceramic, zirconia, and metal dental restoration surfaces contaminated during intraoral try-in.

Regulatory Classification

Identification

Cavity varnish is a device that consists of a compound intended to coat a prepared cavity of a tooth before insertion of restorative materials. The device is intended to prevent penetration of restorative materials, such as amalgam, into the dentinal tissue.

Special Controls

*Classification.* Class II (special controls). The device, when it is an external cleaning solution, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 872.9.

| Resolve 2.0<br>K152322 (predicate device) | CeraClean |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Resolve 2.0 is recommended for use on dental<br>restorations, external to the mouth, prior to<br>insertion into the mouth. After applying<br>Resolve 2.0 to cleanse the restoration, the<br>surface of the restoration should be washed<br>thoroughly with water, and then air dried<br>before placement in the mouth. | CeraClean is an extraoral cleaner of pre-treated<br>ceramic, zirconia and metal restoration<br>surfaces which have been contaminated during<br>intraoral try-in. |

CeraClean's Indications for Use Statement does not include the cleaning information included in the predicate's statement and list pre-treated ceramic, zirconia and metal restorations instead of just general restorations. These differences are not critical to the intended use of the subject device as equivalent cleaning instructions are included within the instructions for use. The increased specificity list the most common materials used in dental prosthetic restorations and fall within the general indication and no not alter the device risk. The subject device is just as safe and effective as compared to the predicate device.

### 510(k) SUMMARY (continued)

Comparison of Technological Characteristics (continued):

| Physical / Mechanical<br>Property | Resolve 2.0<br>K152322 (predicate device) | CeraClean |
|--------------------------------------------------|-------------------------------------------|------------------------------|
| Shear Bond Strength<br>(modified ISO 29022:2013) | Removes saliva contamination | Removes saliva contamination |
| Method of application | Syringe tip w/brush | Syringe tip or brush |
| Method of cleaning | Abrasive | Non-abrasive |
| Method of Removal | Water spray & air dried | Water spray & air dried |
| Delivery configuration | Syringe | Syringe or Bottle |
| Removal | Water Soluble | Water Soluble |

The major differences between Resolve 2.0 and CeraClean are that Resolve 2.0 is a pigmented acrylate resin based gel that uses silicate as a viscosity modifier, includes Chlorohexidine, and is abrasive. CeraClean however, is a pigmented water based gel that uses xanthum gum as a viscosity modifier and does not require abrasive scrubbing to clean the substrate of saliva contamination in preparation for final restoration placement. The lack of acrylate resins in CeraClean does not raise new questions of safety or effectiveness as both devices are water soluble, used outside the mouth, and rinsed off the restorative device prior to placement in the mouth. CeraClean does not include the antimicrobial agent Chlorohexidine. Both devices are pigmented, water soluble, and cleaned substrates are neutral after rinsing.

### 510(k) SUMMARY (continued)

### Performance Data:

Shear bond strength was tested based upon ISO 29022:2013 Dentistry - Adhesion - Notchededge shear bond strength test. Additionally, water solubility and pH (before and after rinse) were tested. A comparison of the physical/mechanical properties of CeraClean to the predicate device is provided in the table below.

| Physical / Mechanical<br>Property | CeraClean |
|--------------------------------------------------|---------------------------------------------------|
| Shear Bond Strength<br>(modified ISO 29022:2013) | Substantially equivalent to the predicate device. |
| Water Solubility | Substantially equivalent to the predicate device. |
| pH (before rinse / after rinse) | Predicate: pH = 6/7, CeraClean pH = 14/7 |
| SEM EDX | Demonstrates device is removed from substrate. |

# Biocompatibility:

An evaluation of biocompatibility was conducted using ISO 7405:2008 and ISO 10993-1:2009. It is concluded from the biocompatibility evaluation and the results of the cytotoxicity testing that CeraClean met the requirements of the test.

#### Conclusion:

It is concluded that the information supplied in this submission has demonstrated that CeraClean is substantially equivalent in design, composition, performance, and intended use to the legally marketed predicate device.
