Intended Use

CELTRA Press is an all-ceramic system for the creation of Occlusal veneers Thin veneers Veneers Inlays Onlays Crowns in the anterior and posterior region 3-unit bridges in the anterior and posterior region 3-unit bridges in the premolar region up to the second premolar as the terminal abutment Crown, splinted crown or 3 unit bridge up to the second premolar placed on top of an implant abutment.

Device Story

CELTRA Press is a high-strength zirconia-reinforced lithium silicate glass ceramic material used by dental laboratory technicians to fabricate all-ceramic dental restorations. The device consists of industrially produced, homogeneous ingots available in varying translucencies. Technicians use a hot-pressing technique within a dental furnace and press investment materials to form the restorations. The process avoids the formation of a surface reaction layer. Finished restorations may be veneered, stained, or glazed using compatible CELTRA Press veneering porcelains. The final product provides aesthetic, durable tooth-colored restorations for patients, including crowns and 3-unit bridges. The device is intended for professional use in a dental laboratory setting.

Clinical Evidence

No clinical data included. Substantial equivalence supported by non-clinical bench testing, including flexural strength, chemical solubility, coefficient of thermal expansion, and radioactivity testing per ISO 6872:2015. Biocompatibility established via testing per ISO 10993-1, 10993-5, and 10993-18.

Technological Characteristics

Zirconia-reinforced lithium silicate glass ceramic. Classified as Type II, Class 4a/4b per ISO 6872:2015. Requires minimum mean flexural strength of 500 MPa. Form factor: industrially produced ingots. Processing: hot-pressing technique in dental furnaces. Biocompatibility: tested per ISO 10993.

Indications for Use

Indicated for patients requiring dental restorations including occlusal veneers, thin veneers, veneers, inlays, onlays, crowns, and 3-unit bridges in anterior, posterior, and premolar regions, or implant-supported restorations.

Regulatory Classification

Identification

Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.

Both CELTRA Press and predicate IPS e.max Press and IPS e.max Press Multi (K120134) meet the requirements of the applicable Class, as detailed in Table under Technological The performance of CELTRA Press meets the requirements of the non-clinical Characteristics. bench testing conducted to support substantial equivalence.

## Toxicological Testing;

Testing according to ISO 10993-1, 10993-5 and 10993-18 (Biological evaluation of medical devices) was completed to characterize the biocompatibility of CELTRA Press. Results of the testing conducted in accordance with ISO standard support the biocompatibility of CELTRA Press. CELTRA Press veneering porcelains (accessory) were compared to reference device, Quattro Porcelain System (K091706) for biocompatibility purposes.

## Clinical Performance Data.

Not applicable. No data from human clinical studies has been included to support the substantial equivalence of the CELTRA Press.

## Conclusion Regarding Substantial Equivalence

CELTRA Press supports substantial equivalence to the predicate IPS e.max Press and IPS e.max Press Multi cleared under premarket notification K120134 because:

- It has the similar intended use as the predicate ●
- . Has similar technological characteristics as the predicate, with the exception of flexural strength. CELTRA Press meets the requirement of flexural strength for Type II, Class 4 materials.
