What Does A Dental Furnace Do?

A dental furnace, also known as a dental oven, is a machine used in the production of ceramic dental restorations such as crowns, bridges, inlays, and onlays. It relies on high temperatures and pressures to process ceramic material into its hardened state. There are different types of dental furnaces, including firing furnaces, sintering furnaces, pressing furnaces, and glazing furnaces.

The working of a dental furnace involves a digital programmable function and various features such as high-quality garments, a large touch panel, high-temperature precision, and high vacuum accuracy. Firing and pressing furnaces are often combined into a single unit to treat conventional and glass ceramics. These furnaces can handle materials that have been milled, stacked, or waxed-up and invested for pressing.

The primary purpose of a dental furnace is to provide benefits to dental practices. It allows dentists to produce ceramic dental restorations in-house, eliminating the need to outsource to off-site laboratories. This saves time and money while also providing better customization, productivity, and quality of service.

There are three main types of dental furnaces: ceramic furnaces, combination furnaces, and sintering furnaces. Ceramic combination furnaces are designed for both burning and pressing ceramic repairs and can work with various dental materials and lab operations. Sintering furnaces are capable of reaching the high temperatures required for zirconia processing after milling.

The uses of dental furnaces include altering the physical properties of materials at high temperatures, such as in heat treatment processes. They are commonly used in dentistry laboratories for scientific studies. Some specific applications include sintering translucent zirconia and dental ceramics operations.

The advantages of dental furnaces or dental ovens include easy loading and removal of samples, such as molten glass and dental zirconia. The furnace uses an electrically operated elevator hearth to lift the load into the heated zone, ensuring uniform heating throughout the chamber.

In summary, a dental furnace is a machine used in the production of ceramic dental restorations. It utilizes high temperatures and pressures to process ceramic material into a hardened state. The different types of dental furnaces offer various functions and benefits, including in-house production, customization, and improved quality of service.
