Guide to Buying a Dental Furnace: Things You Need To Consider As A Dental Lab Owner
Every modern dental laboratory is equipped with one device – a dental furnace. It is the machine used to transform raw ceramic blocks and pressed materials into the crowns, veneers, and bridges used by the patients. If you manage a laboratory or are going to start one, knowing what a dental furnace is and how it works is essential for consistent restoration processes.
What Is a Dental Furnace?
A dental furnace is a piece of equipment used to sinter, press, or glaze dental ceramics at temperatures ranging from 600°C to 1600°C depending on the material type. Zirconia, lithium disilicate, porcelain – these materials react to heat differently and thus need different processing. Therefore, modern dental furnaces have programmable cycles.
What Is the Working Principle of a Furnace?
It is one of the most common questions asked by a new lab technician, and here is an honest answer. The working principle of a furnace is based on controlled resistive heating. Heating elements (molybdenum disilicide or kanthal wire) are electrically charged which allows to gradually heat the chamber according to a pre-programmed program. The thermocouple inside constantly measures the heat levels and sends them to the controller ensuring a stable temperature and preventing fluctuations of even one degree. Such precision in a dental lab application helps avoid cracking, discoloration, or improper sintering – problems that can lead to expensive rework of a tooth restoration.
Dental Ceramic Furnace: Not Your Average Oven
A dental ceramic furnace is definitely not an oven you can use for baking cakes. Unlike conventional ovens, dental furnaces have vacuum firing capability, high rates of heat up, and microprocessor-controlled programs optimized for dental porcelain and pressable ceramics. Vacuum firing provides removal of the air bubbles present during glazing process, and it gives crowns their translucent natural look.
Price of Dental Furnace: How Much Do You Need to Spend?
The price of a dental furnace is determined by many factors, including size of chamber, vacuum ability and manufacturer reputation – there are affordable models for beginners on one side and costly high-end zirconia sintering furnaces that have a multi-stage programming on the other hand. However, keep in mind that you should take into account costs of replacing elements and calibration support which influence your final price of owning such equipment for 5 to 10 years period.
Dental Ceramic Furnace Price in India: Realistic Estimate
Speaking about price of dental ceramic furnace in India, it should be mentioned that it depends on whether it is imported or produced domestically. Imported equipment by reliable European and Korean companies is normally more expensive because of import duties and service network which is needed, while domestic equipment is relatively cheap and easy to maintain.
What Is the Price of Ceramic Furnace in India Compared Internationally?
When laboratories ask what is the price of ceramic furnace in India compared with the price internationally, it is possible to say that there are differences only in terms of currency exchange, shipping costs and GST which make prices in India cheaper for new companies.
Conclusion
Your choice of dental furnace will determine quality of your laboratory work for many years. Analyze working principle, vacuum options and cost of owning it before making your decision.
