#### 5 INDICATIONS FOR USE

Glazing of individually designed dental restorations from dental ceramics.

The CEREC SpeedGlaze Spray is used for coating dental restorations made from Sirona CAD/CAM materials. It is administered extra-orally and is indicated for crowns, inlays, onlays, partial crowns and bridges in the anterior and posterior tooth region.

#### DEVICE DESCRIPTION AND FUNCTION б

The CEREC SpeedGlaze Spray is used to glaze dental restorations made from the Sirona CAD/CAM materials CEREC Zirconia, inCoris TZI C, CEREC Blocs C, CEREC Blocs C PC and CEREC Blocs C In. The spray meets the requirements of the ISO 6872:2008 "Dentistry - Ceramic materials". The product consists of a coated aluminum can cap, filled with a glaze and a valve and a spray nozzle, for applying the glaze. The CEREC Speed Glaze Spray is suitable for the coating of dental restorations from the Sirona CAD/CAM materials: CEREC Zirconia, inCoris TZI C, CEREC Blocs C, CEREC Blocs C PC and CEREC Blocs C In. The CEREC SpeedGlaze spray has to be administered extraorally.

It is indicated for the following parts of dentistry:

- crowns, inlays, onlays, partial crowns and bridges in the anterior and posterior tooth region.
The product has 8 components as shown below:

| Component | Remark / Description |
|------------------------|----------------------------------------------|
| 1. Can: | Aluminum monobloc spray can |
| 2. Valve: | For releasing the contents when engaged |
| 3. Can cap | PP - Polypropylene, Plastic |
| 4. Spray nozzle: | For spraying onto restoration |
| 5. 14mm Glass balls | For mixing of the components before spraying |

The properties including the firing temperature, particle size and solubility are shown below. The components of the CEREC SpeedGlaze can also be found in the subsequent table.

| Property | Value |
|----------------------------------|-------------------------------------------------------|
| Coefficient of thermal expansion | $7.5 x 10^{-6} x K^{-1} \pm 0.5 \cdot 10^{-6} K^{-1}$ |
| Transformation temperature | 490° C ± 10°C |
| Bending strength | > 50 MPa |
| Chemical solubility | < 100 µg x cm-2 |
| Granulometry/particle size | D50 = 6µm ± 0.6µm |
| Cytotoxicity | no cytotoxicity |
| Radioactivity | < 1 Bq x g-1 U238 |

#### PRINCIPLES OF OPERATION 7

The underlying scientific concept is that the glaze is applied by spray jet on to the surface of the ceramic restorations and a firing process is carried out in the chairside oven CEREC SpeedFire. Commercially available chairside ovens like the Vita Vacumat and Ivoclar Programat can also be used.

The product is composed of a can which is coated with epoxyphenol and a spray mechanism including a valve, nozzle and can cap. These allow for the extraoral spraying of the glaze onto the restoration.

The CEREC SpeedGlaze consists mainly of a glaze ceramic, organic excipients and propellant gas. When the valve assembly is engaged, the composition from the container is released and sprayed onto the restoration. During finring, the organic excipients burn without leaving any residue.

The glaze meets the requirements of the ISO 6872:2008 "Dentistry - Ceramic materials".

### TECHNOLOGICAL CHARACTERISTICS SUMMARY 8 Comparison to Predicate Device

The CEREC SpeedGlaze is similar to the Nova Ceramic Spray Glaze by Enamelite LLC. The CEREC SpeedGlaze is intended for coating dental restorations. It is made of silicate glass and is applied to dental restorations in an aerosolized form. Similarly, the Nova Ceramic Spray Glaze is intended for glazing dental restorations and is made of glass frit with similar compositions as the CEREC glaze material. It has the same classification name (Porcelain Powder for clinical use) and product code (EIH) as the CEREC SpeedGlaze. Both devices consist of refined aerosol delivery systems used to apply the glaze. They have the same working principle in that the glaze is applied by a spray jet onto the restoration and a firing process is carried out to melt the glaze. The CEREC SpeedGlaze has similar composition to the Nova Ceramic Spray Glaze. Both sprays use non-CFC propellants to eject the contents. Similar wetting agents are also used in both sprays.

Both spravs require firing of the restoration after application of the glaze. The main difference between the CEREC SpeedGlaze and the Nova Ceramic Spray Glaze is the differences in organic excipients (solvents and pigments). However this is not significant as the excipients burn without residue upon firing. Furthermore properties such as bending strength, coefficient of thermal expansion, cytotoxicity, and chemical solubility were tested according to ISO standards ISO 6872 and ISO 7405, and meet the requirements.
