Intended Use

GC Aadva Zr Disks are used to fabricate crown and bridge frameworks, both anterior and posterior.

Device Story

GC Aadva Zr Disk is a dental material used by dental laboratory technicians to fabricate crown and bridge frameworks. The device consists of zirconia disks that are milled using CAD/CAM systems to create custom dental restorations. These frameworks are subsequently veneered with porcelain to produce final dental prostheses. The device is intended for use in both anterior and posterior regions of the mouth. By providing a high-strength, biocompatible ceramic framework, the device enables the restoration of tooth structure, improving patient function and aesthetics.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Material: Zirconia (zirconium dioxide) ceramic disk. Form factor: Pre-sintered or fully sintered disk for CAD/CAM milling. Energy source: None (passive material). Connectivity: None. Sterilization: Not applicable (non-sterile dental material).

Indications for Use

Indicated for the fabrication of anterior and posterior crown and bridge frameworks in dental patients.

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.
