This Mestra microwave zirconia sintering furnace is designed for dental laboratories looking for a fast, accurate and energy-efficient solution for daily zirconia crown, bridge and framework production.
Microwave zirconia sintering for dental crowns, bridges and frameworks
This microwave zirconia sintering furnace is engineered for dental labs producing zirconia crowns, bridges and frameworks. It supports a rapid, homogeneous temperature rise, shorter sintering cycles and significantly reduced power consumption.
It helps increase daily production capacity while maintaining excellent dimensional stability and a clean surface finish on zirconia restorations after sintering.
Why choose microwave technology for zirconia sintering?
- In a conventional resistive furnace, heat comes from the outside.
- With microwave sintering, heat is generated inside the zirconia structure for improved thermal homogeneity.
- Fast sintering cycles up to 1550 °C in approximately 110 minutes.
- Controlled cooling of approximately 130 minutes down to 300 °C.
- Lower energy costs thanks to a low average power draw of approximately 800–1100 W.
- Short cycles help manage same-day urgent zirconia cases for dental practices.
Microwave vs conventional sintering furnace
- Fewer complex holding plateaus and a more direct, homogeneous temperature rise.
- Overall cycle time of around 4 hours, including cooling.
- Much less heat released into the dental laboratory.
- Significantly lower electricity consumption.
- No molybdenum disilicide heating elements.
- Simplified maintenance and faster, more cost-effective after-sales service.

FAQ – Microwave zirconia sintering furnace
What are the benefits of a microwave zirconia sintering furnace for a dental lab?
A microwave zirconia sintering furnace provides volumetric heating: energy is deposited inside the zirconia restorations instead of coming only from external heating elements.
This improves thermal homogeneity, reduces the overall cycle time and helps the laboratory produce zirconia crowns and bridges more efficiently.
How does a typical zirconia sintering cycle work?
Start the program with a cold furnace and load your zirconia frameworks according to the manufacturer’s recommendations.
The temperature rise, holding plateau and cooling phase must be controlled according to the mass, geometry and total load of the zirconia restorations.
What daily maintenance is recommended for reliable results?
Regular preventive maintenance keeps the microwave sintering furnace stable and consistent from batch to batch.
Keep the chamber, sintering bowl and zirconia beads clean, avoid overloading the bowl and check the condition of the susceptors and magnetron if performance drops.
