Intended Use

The OPC 3G All-Ceramic System, Core and Overlay Porcelains comprise a lithium disilicate glass-ceramic core used for all-ceramic dental restorations. Subsequent layers of porcelain are applied over top to provide additional aesthetics and characterizations. This system offers high strength, low wear, the aesthetics of a metal-free system, and better thermal shock properties due to the lower thermal expansion of the materials used. The dental restoration is prepared by a lost wax technique. The dental restorations are designed in a wax pattern and invested into refractory. The refractory is burned out to remove the wax and leave a cavity of the dental design. Pellets of 3G All-Ceramic are placed into the investment cavity and transferred to a hot pressing furnace where the investment/pellets are brought to a higher temperature. The temperature is maintained long enough for the glassceramic to become molten and then pressed into the cavity creating an exact duplicate of the original wax pattern. In addition, dental restorations can be made by forming the material into pre made blocks of ceramics, which are milled to the coping/bridge shape by CAD/CAM equipment. The OPC 3G All-Ceramic System, Core and Overlay Porcelains are intended for either hot pressing or CAD/CAM machining all-ceramic dental restorations. The OPC 3G All-Ceramic System, Core and Overlay Porcelains should be used with 3G All-Ceramic materials only and not intermixed with other manufacturers products/porcelains. The system is used for fabrication of dental restorations including inlays, onlays, veneers, single units, and anterior bridges up to the first premolar.

Device Story

Lithium disilicate glass-ceramic system for dental restorations; utilizes lost wax technique (wax pattern, refractory investment, hot pressing furnace) or CAD/CAM milling of pre-made ceramic blocks; system includes core pellets, stains, bodies, incisals, glazes, and associated laboratory accessories; used by dental professionals for fabrication of inlays, onlays, veneers, single units, and anterior bridges; provides metal-free aesthetics, high strength, and thermal shock resistance; output is a custom-fitted dental restoration.

Clinical Evidence

No clinical data provided; substantial equivalence based on material composition and functional similarity to predicate devices.

Technological Characteristics

Lithium disilicate glass-ceramic material; fabrication via hot pressing or CAD/CAM milling; system includes core pellets, stains, bodies, incisals, and glazes; non-electronic, mechanical/material-based dental system.

Indications for Use

Indicated for fabrication of all-ceramic dental restorations including inlays, onlays, veneers, single units, and anterior bridges up to the first premolar.

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.

Predicate Devices

• Finesse All-Ceramic Core (K971869)
• Empress2 Core (K982616)

### Date Summary Prepared: May 26, 2000

The compositions for 3G All-Ceramic Core is similar to Finesse All-Ceramic Core, K971869, Dentsply International and Empress2 Core, K982616, Ivoclar North America, in both composition and function. I.ikewise, the 3G All Ceramic overlay used in conjunction with the 3G Core is also similar to the overlay porcclains for these same cores, Finesse Porcelain and Empress2 Porcclain. Because of these similarities to predicate devices, the material is substantially equivalent.

The OPC 3G All-Ceramic System, Core and Overlay Porcelains comprise a lithium disilicate glassceramic core used for all-ceramic dental restorations. Subsequent layers of porcelain are applied over top to provide additional aesthetics and charactcrizations. This system offers high strength, low wear, the aesthetics of a metal-free system, and better thermal shock properties due to the lower thermal expansion of the materials used.

The dental restoration is prepared by a lost wax technique. The dental restorations are designed in a wax pattern and invested into refractory. The refractory is burned out to remove the wax and leave a cavity of the dental design. Pellets of 3G All-Ceramic are placed into the investment cavity and transferred to a hot pressing furnace where the investment/pellets are brought to a higher temperature. The temperature is maintained long enough for the glass-ceramic to become molten and then pressed into the cavity creating an exact duplicate of the original wax pattern.

In addition, dental restorations can be made by forming the material into pre made blocks of ceramics, which are milled to the coping/bridge shape by CAD/CAM cquipment.

The OPC 3G All-Ceramic System is intended for either hot pressing or CAD/CAM machining allceramic dental restorations. The 3G All-Ceramic System should be used with 3G All-Ceramic materials only and not intermixed with other manufacturers products/porcelains. The system is used for fabrication of dental restorations inlays, onlays, veneers, single units, and anterior bridges up to the first premolar.

The OPC 3G All-Ceramic System, Core and Overlay Porcelains will include Corc pcllcts, Corc Stains, Bodies, Incisals, Glazes, Investment, Investment Liquids, Acid Solutions (Shipped Separately), Acid Neutrilizers, Glaze Liquids, Disposable Plungers, Paper Rings, Plastic Scoops, MSDS and Instructions.
