## Indications for Use

The Zmatch® Block is intended for CAD/CAM fabrication of all-ceramic dental restorations. The Zmatch® Block is used for the manufacturing of inlays, onlays, veneers, crowns and bridges.

## Device Story

Zmatch® Block is a pre-formed, machineable zirconium oxide ceramic blank; available in partially-sintered state; offered in two material composition models (A-type and B-type). Used by dental laboratories or clinicians with CAD/CAM milling equipment to fabricate dental restorations (inlays, onlays, veneers, crowns, bridges). Device serves as raw material for milling; final restoration is placed by dental professionals. Benefits include patient-specific, high-strength ceramic restorations.

## Clinical Evidence

No clinical data; substantial equivalence based on material and technological characteristics.

## Technological Characteristics

Pre-formed machineable ceramic blank composed of zirconium oxide. Available in partially-sintered form. Two models (A-type and B-type) with varying material compositions. Designed for CAD/CAM milling.

## Regulatory 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.
