- Heating Temperature Range
- Usually, the heating temperature of porcelain fused to metal dental furnaces can range from 300°C to 1000°C. This wide temperature range enables it to meet different requirements in the process of porcelain fusion to metal, such as preheating, sintering and glazing.
- Temperature Accuracy
- The temperature accuracy is generally within ±1°C to ±2°C. High temperature accuracy is crucial to ensure the quality of porcelain fused to metal restorations, as it can prevent underfiring or overfiring of the porcelain, thus affecting the color, transparency and strength of the restoration.
- Heating Rate
- The heating rate can usually be adjusted within the range of 5°C/min to 20°C/min. A suitable heating rate is beneficial for the porcelain powder to be evenly sintered and fused with the metal substrate, avoiding thermal stress and cracks.
- Inner Chamber Size
- Common inner chamber sizes are about 150mm×150mm×150mm to 300mm×300mm×300mm. The size of the inner chamber determines the number and size of dental restorations that can be processed at one time, which can meet the needs of different dental laboratories and clinics.
- Power
- The power of porcelain fused to metal dental furnaces is generally between 2kW and 5kW. The power affects the heating efficiency and speed of the furnace. Sufficient power can ensure that the furnace can reach the set temperature quickly and maintain a stable temperature state.
- Porcelain Fused to Metal Crown Restoration
- It is mainly used to fabricate porcelain fused to metal crowns. After the metal crown framework is fabricated by casting or other processes, the porcelain powder is applied to the surface of the metal framework. The porcelain fused to metal dental furnace is used to sinter the porcelain powder at high temperature, so that the porcelain is firmly fused to the metal surface to form a porcelain fused to metal crown with good aesthetics and function.
- Porcelain Fused to Metal Bridge Restoration
- For the restoration of dental bridges, the porcelain fused to metal dental furnace is used to sinter and fuse the porcelain and metal components of the bridge. It can make the bridge fit the patient's oral cavity structure accurately, restore the missing teeth function and aesthetics, and improve the patient's chewing efficiency and quality of life.
- Dental Inlay and Onlay Restoration
- In some cases, porcelain fused to metal inlays and onlays need to be fabricated. The porcelain fused to metal dental furnace can be used to sinter the porcelain on the metal substrate to make inlays and onlays that are more suitable for the patient's tooth shape and occlusion, playing a role in repairing damaged teeth and protecting the remaining tooth tissue.
- Customized Dental Prosthetic Fabrication
- According to the specific needs of patients, such as special tooth shapes, colors or functional requirements, the porcelain fused to metal dental furnace can be used to fabricate customized dental prosthetics. It provides a powerful tool for dental technicians to realize personalized dental restoration schemes.
In conclusion, porcelain fused to metal dental furnaces play a vital role in the field of dental restoration, helping dental professionals to provide patients with high-quality, aesthetic and functional dental prosthetics.
