Dental Furnace
Dental furnaces, also known as dental ovens, are utilized in the production of ceramic dental restorations like crowns, bridges, inlays, and onlays. These furnaces can achieve high temperatures and pressures to process ceramic material into a final hardened state.
There are several types of dental furnaces available, each designed for a specific purpose.
Ceramic furnaces are used to process conventional ceramics, while combination furnaces can operate under the necessary pressure to work with pressable ceramics. Sintering furnaces can reach extreme temperatures required for processing zirconia after milling. Additionally, there are glazing furnaces that are utilized for setting certain stains and glazes that add the final shade details to a restoration.
When selecting a dental furnace, ensure it's capable of processing the materials you work with. Choose furnaces that are easy to clean and maintain between uses. It's essential to invest in a furnace from a reputable manufacturer to ensure its reliability and longevity.
Types of dental furnaces
Ceramic combination furnaces are designed to fire and press ceramic restorations, making them versatile for various dental materials and lab workflows. These furnaces offer the flexibility needed to work with multiple materials.
Sintering furnaces are specialized equipment designed to process zirconia after milling. These furnaces can reach the extreme temperatures required for the sintering process, where zirconia undergoes significant shrinkage.

FAQ
What is dental furnaces?
A dental furnace, also known as a dental oven, is a piece of equipment used in the production of ceramic dental restorations such as crowns, bridges, inlays, and onlays. The furnace can reach high temperatures and pressures to process ceramic material into a hardened, final state. There are different types of dental furnaces, including ceramic combination furnaces, sintering furnaces, and glazing furnaces. Modern dental furnaces are microprocessor controlled, providing the benefit of programmability and a memory system that can remember up to 200 different programs, all of which can be executed precisely by the user.
What are the different types of dental furnaces?
The different types of dental furnaces include ceramic furnaces, ceramic combination furnaces, sintering furnaces, and glazing furnaces. Ceramic furnaces process conventional ceramics, ceramic combination furnaces add the ability to operate under the pressure necessary to work with pressable ceramics, sintering furnaces are capable of reaching extreme temperatures required to process zirconia, and glazing furnaces are used for setting certain stains and glazes. When selecting a dental furnace, it is important to choose one that is capable of processing the materials used in the practice or lab, is easy to clean, and is properly maintained.
What is the temperature of a dental furnace?
The temperature of a dental furnace typically ranges between 600°C and 1600°C. The firing result obtained is influenced by the accuracy of the actual temperature. Different dental furnaces can have identical digital external displays, yet different results regarding the degree of firing can be identified when processing the same ceramics under otherwise similar conditions. The International Standard levels the currently existing differences between the final calibration of the dental furnaces based on the factory of origin through a final adjustment of the temperature control in the firing chamber by means of a thermocouple at e.g. 800°C.
What is the use of porcelain furnace?
A porcelain furnace is used in dentistry to create dental porcelain, which is an unglazed ceramic material used for dental restorations such as crowns and veneers. The furnace heats the ceramic material until it is soft enough to shape, and then it is cooled and polished to create the desired tooth pattern. There are two main types of dental porcelain furnace systems: direct-fired or cold-press fired, and hot-pressed or heat-fused fired. Direct-fired technology uses an external source to directly fire the ceramic material, making it more cost-effective than indirect-fired technologies.
