Device Story

Nacera Pearl consists of pre-sintered yttria-stabilized tetragonal zirconia (Y-TZP) milling blanks; used by dental technicians to fabricate custom all-ceramic restorations. Process: technician performs intraoral or impression/model scan; designs restoration via CAD software; CAM milling center machines blank to desired geometry; final sintering to full density. Finished restorations used as full-contour prostheses or veneered with dental porcelain. Device enables patient-specific dental reconstruction; improves aesthetic and functional outcomes for anterior/posterior tooth replacement.

Clinical Evidence

Bench testing only. Testing included density, microstructure, flexural strength, radioactivity, thermal expansion, chemical solubility, open porosity, tensile strength, elastic limit, and Young's modulus per ISO 13356 and ISO 6872 standards. Results demonstrate performance comparable to predicate devices.

Technological Characteristics

Material: Yttria-stabilized tetragonal zirconia (Y-TZP) complying with ISO 6872 and ISO 13356. Form factor: Pre-sintered milling blanks (discs, cylinders, bars, cubes). Processing: CAD/CAM milling followed by final sintering. Connectivity: None (material component).

Indications for Use

Indicated for fabrication of custom-made all-ceramic dental restorations, including single crowns, bridgework, inlays, onlays, and primary telescopic crowns for anterior and posterior applications in patients requiring dental prosthetics.

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 main differences between the subject device and the noted predicates are based on slight variations in shade (the end sintered dental restorations shade differences are caused by the chemical composition differing mass fractions of the ,oxide' components) as well as physical properties such as density and flexural strength.

Performance Testing In order to demonstrate comparability of Nacera Pearl dental materials to the predicate devices a series of testing was performed according to ISO 13365 - in particular density, microstructure, flexural strength, and radio activity. Thermal expansion and chemical solubility was also performed according to ISO 13356. Open porosity, tensile strength, elastic limit, bending strength, Young's modulus comparative testing was also performed.

Submitter: Doceram Medical Ceramics GmbH

The results of this testing showed that the physical properties and performance of the subject device are comparable to the identified predicates.

SE Conclusion: In conclusion, it has been shown that all devices are dental materials manufactured from the same porcelain powder Y-TZP, have comparable indications for use, technical, physical, chemical, and biological properties and characteristics, and have the same aesthetic and diagnostic function. Therefore, it can be demonstrated that Nacera Pearl dental materials are substantially equivalent to the predicate dental devices, Nacera Z, Nacera Z Medium, BeCe CAD Zirkon HT+, StarCeram Z-Med, and ZENO Zr.
