Zirconia Sintering Furnace, the Key to Producing Dentures

With the development of the times, more and more people begin to pay attention to the health and aesthetics of teeth. In recent years, the denture industry has been developing more and more rapidly and has a wide range of development prospects.

However, how are the dentures produced and finally put into the market and customers? This article will reveal the key to the production of dentures - the zirconia sintering furnace.

Learn about Zirconia Materials

To deeply understand what a zirconia sintering furnace is, you first need to understand what zirconia is.

What is Zirconia?

Zirconia, also known as zirconium dioxide, is the main oxide of zirconium. Normally, zirconia is a white, odorless, and tasteless crystal, which is difficult to dissolve in water, hydrochloric acid, and dilute sulfuric acid.

Zirconia is an inorganic non-metallic material that is resistant to high temperature, corrosion, abrasion, and has excellent electrical conductivity.

In addition to its traditional applications in refractory materials and ceramic pigments, zirconia is also used in high-tech fields such as electronic ceramics, functional ceramics, and structural ceramics.

With the development of dental technology and dental materials, doctors and patients can use more and more restorative materials. Due to its good biocompatibility, high strength, and ideal aesthetic effect, zirconia is the most popular dental material on the market today.

Many dental laboratories, hospitals, etc. have purchased dental sintering furnaces from Brother Furnace, which are dedicated to the sintering of zirconia denture crystals.

Why are More and More People Choosing Zirconia Materials?

Biocompatibility: Zirconia material has good biocompatibility and is less likely to trigger inflammatory reactions, helping to protect the health of the hard and soft tissues around the implant.

Artistic: The color of the zirconia base crown is closer to that of a natural tooth and does not show through the soft tissues as metal materials do, avoiding the greyness of the marginal tissues.

Antibacterial properties: Due to the low free energy and wettability of the zirconia material surface, bacterial adhesion is reduced, thus reducing the risk of peri-implant disease.

High strength and durability: zirconia material has excellent strength and abrasion resistance which allows it to withstand higher occlusal forces in the oral cavity and wear and tear during long-term use.

Reduced risk of allergies: Zirconia material contains no metal components, reducing the possibility of allergic reactions and making it particularly suitable for patients with metal allergies.

Corrosion resistance: Post-core crowns made from zirconia are chemically stable and resistant to corrosion and decomposition, ensuring long-term oral health and longevity.

Take the T-series of Brother Furnace’sT-Crystal Chamber Sintering Furnace as an example. This sintering furnace is designed for the sintering of samples such as zirconia denture crystals and is now widely used in dental laboratories for zirconia sintering as well as in laboratories for small batch sintering.

Working Principle of Zirconia Sintering Furnace

Zirconia sintering furnaces generate high temperatures using heating elements, which distribute the heat uniformly in the furnace chamber, thus realizing the densification and sintering process of zirconia powders in a controlled environment.

During the sintering process, zirconia powders undergo physicochemical changes such as intergranular rearrangement, densification, and grain growth at high temperatures. This process improves the mechanical properties of the material by eliminating intergranular pores and forming a strong crystal structure.

The operating temperature range is typically between 1200°C and 1600°C to ensure optimum sintering properties of the zirconia material.

Features of Zirconia Sintering Furnace from Brother Furnace

1. High-purity mullite fiber: stable choice of furnace chamber material.

The T-Crystal Dental Furnace uses high-purity polycrystalline mullite fibers as the furnace chamber material. This material is not only highly stable at high temperatures, but also has excellent refractory and thermal insulating properties, enabling the furnace chamber to withstand high temperatures for long periods without deformation. In addition, the chemical resistance of mullite fibers makes it possible to maintain excellent performance in a variety of harsh environments, ensuring the service life and efficiency of the sintering furnace.

2. Compact and lightweight: a sintering furnace for the laboratory and home workshop.

Designed with a focus on lightweight and compactness, this zirconia sintering furnace’s lightweight and compact size makes it ideal for small laboratories and home-based work environments. Whether in a research institute, laboratory, or personal studio, this device can easily fit into a limited space without compromising its high performance.

3. Low-power design: 1.5kW household circuitry can be satisfied.

The power is only 1.5kW, which makes this sintering furnace extremely friendly to the demand for electricity. Users do not need to worry about special high-power circuits, just rely on ordinary circuits in the home that can meet the conditions of use, greatly reducing the complexity and cost of installation and use of equipment.

4. Extremely fast temperature rise: high performance to ensure sintering quality.

Rapid temperature rise can quickly reach the required working temperature. This ability to heat up quickly not only improves work efficiency but also better control of temperature changes in the sintering process, thus ensuring the quality and consistency of the sintered samples.

5. Intelligent touch control: easy operation and multi-program storage.

Equipped with a 7-inch high-definition touch screen, the operation is simple and intuitive, enabling users to easily set and monitor various parameters. In addition, the device can store 30 different process programs, so users can quickly call the preset program according to different experimental needs, simplify the operation process, and improve work efficiency and experimental repeatability.

Maintenance of Zirconia Sintering Furnace

To ensure the long-term stable operation of the zirconia sintering furnace, regular maintenance is essential. The following are some common maintenance measures:

1. Regular cleaning of the furnace chamber: remove dust and impurities in the furnace chamber regularly to keep the chamber clean.

2. Check the resistance element: regularly check the integrity of the resistance element to prevent the decline in heating efficiency due to aging or damage.

3. Calibrate the temperature control system: calibrate the temperature control system regularly to ensure the accuracy of temperature control.

Market Application of Zirconia Sintering Furnace

The application of zirconia sintering furnaces in the dental industry is not only limited to denture production, it is also widely used in other high-tech fields, such as aerospace, electronics, and new energy.

1. Dental field: In the dental field, zirconia sintering furnace is an important piece for manufacturing high-precision and high-quality dentures, which helps to improve the aesthetics and durability of dentures.

2. Other industrial applications: Zirconia sintering furnaces are also used to manufacture high-performance ceramic components, such as ceramic parts for automobile engines and insulating materials for electronic products.

The importance of zirconia sintering furnace in denture production cannot be ignored. It not only ensures the high quality and precision of zirconia dentures, but also improves the production efficiency and the market competitiveness of the products. The zirconia sintering furnace will surely provide a quality solution for more dental professionals and patients’ choice.

Brother Furnace’s zirconia sintering furnaces are now an indispensable piece of equipment in dental laboratories and laboratories. In the future, Brother Furnace will continue to optimize its equipment and insist on technological advances to help the development of the denture industry.
