Intended Use

Ceramill Zold FX preshade are blanks made of zirconium oxide (ZrO2) for type II, class 5 dental applications in accordance with DIN EN ISO 6872. They are used for manufacturing permanent and removable prosthetic restorations (e.g., crowns and three-unit bridges to the molar region) using CNC milling machines (e.g., Ceramill Motion).

Device Story

Ceramill Zolid FX is an all-ceramic dental material composed of Yttria-Stabilized Zirconium Oxide (YSZ) provided as U-shaped disks. Dental technicians use CNC milling machines (e.g., Ceramill Motion) to fabricate copings and substrates for fixed all-ceramic restorations from these blanks. Following milling, the material undergoes oven firing to harden the ZrO2. The device is used in dental laboratories by technicians to produce permanent and removable prosthetics, such as crowns and three-unit bridges. The final restoration is placed by a dentist. The material provides a durable, biocompatible core for dental prosthetics, benefiting patients by restoring dental function and aesthetics.

Clinical Evidence

No clinical data. Substantial equivalence is supported by non-clinical bench testing, including flexural strength (4-point bending), Weibull modulus, Vickers hardness, density, thermal expansion, open porosity, modulus of elasticity, radioactivity, and biocompatibility (cytotoxicity, chemical analysis) per ISO 10993 and ISO 6872 standards.

Technological Characteristics

Material: Yttria-Stabilized Zirconium Oxide (ZrO2 + HfO2 + Y2O3 ≥ 99.0%). Form factor: U-shaped disks. Sintering: 1450°C for 2 hours. Standards: ISO 6872:2008, ISO 13356, ISO 9396, ANSI/ADA No. 69:2010. Biocompatibility: ISO 10993-1, -5, -12, -18, and ISO 7405. Non-sterile, single-use.

Indications for Use

Indicated for patients requiring permanent or removable dental prosthetic restorations, including crowns and up to 3-unit bridges in the anterior and posterior regions.

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.

The "Ceramill Zolid FX" complies with the applicable voluntary standard for risk management, ISO 14971:2007, Medical devices - Application of risk management to medical devices. The risk management activities verified that risks have been eliminated or reduced to acceptable levels from a benefit/risk assessment.

The "Ceramill Zolid FX" meets all the requirements for overall design and biocompatibility, and performance testing confirms that the output meets the design inputs and specifications.

#### 10. Clinical Performance Data

There was no clinical testing required to support the medical device as the indications for use is equivalent to the predicate device. These types of devices, including the predicate devices, have been on the market for many years with a proven safety and efficacy for the use of the device (there have been little to no adverse events reported). The non-clinical testing detailed in this submission supports the substantial equivalence of the device.

#### 11. Statement of Substantial Equivalence

By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device. Or the device has the same intended use and different technological characteristics that can be demonstrated that the device is substantially equivalent to the predicate device, and that the new device does not raise different questions regarding its safety and effectiveness as compared to the predicate device.

The proposed device and the predicate have the same intended use. The technological characteristics are identical or similar.

It has been shown in this 510(k) submission that the difference between the "Ceramill Zolid FX" and the predicate devices do not raise any different questions regarding its safety and effectiveness. The "Ceramill Zolid FX", as designed and manufactured, is determined to be substantially equivalent to the referenced predicate devices.
