Zircoya by Opti’waves,
a powerful ally for prosthetists

The Zircoya oven uses microwave technology to sinter dental zirconia in just 40 minutes, while this can last up to 15 hours with a traditional oven. This time saving gives more flexibility to the prosthetists who can launch several thermal cycles and cook more than 100 elements in one day !

With Zircoya :

  • don’t wait to fill your oven to start cooking
  • sinter several types of zirconia in the same day
  • limit the risk of anomalies with pre-programmed and adapted cycles
  • improve the structural quality of your dentures
  • deliver your prostheses on time
  • divide your sintering energy bill by 10 or more*
  • increase flexibility
  • improve your productivity
  • increase your profitability

With Zircoya, the prosthetists regain the advantage over the competition of low-cost countries with a 100% made in France oven !

*Calculations done, based on 30 prostheses per day and by comparing the electrical power and cooking time of a traditional sintering oven and the Opti’Waves oven. If the number of prostheses performed per day is lower the greater the energy saving is./p>

How works Zircoya ?

Eco-design of products :

Opti’Waves supports Zircoya crucibles and ovens from their availability to their end of life. This includes : resupply, timing, automatic prediction of crucible orders and a service of repair as soon as possible (48 hours in France).

Technical characteristics :

Cooking from the heart

Volume heating

ensures a more homogeneous microwave heating, with a penetration distance of the order of the centimetre (cm)

Surface heating

generates heating of the entire oven enclosure with a penetration distance of the order of the micrometer (μm)

The Zircoya oven reaches 1700°C and cooks all the dental zirconia available on the market. Equipped with a patented crucible, it ensures a fast, homogeneous and focused high temperature heating on the prosthesis. This technique allows the sintering of complex parts such as the crown, the bridge or the complete mandible.

In addition to reducing the cooking time by 15, the volumetric heating limits the deformation of the parts for optimal prostheses that have the same microstructural characteristics (density and scanning electron microscope analysis) than those treated with a traditional Oven.

Identical Properties

Diffusion phenomenon in ceramics

(1 surface roughness, 2 porosity, 3 secondary phase, 4 grain boundary)

Even on a smaller scale, the transparency and translucency of polycrystalline ceramics are closely related to their microstructure (Figure). It is true that the absorption, reflection and diffusion phenomena, which affect the optical transmission rate, are due to the microstructural defects of the material.

Comparison of sintering trajectories between microwave (red) and conventional heating

The figure shows the sintering trajectories obtained for the microwaves and conventional sintering of zirconia. It should be noted that all the experimental points obtained adopt a single sintering trajectory and this, whatever the sintering process and the thermal cycle used (heating rate, bearing temperature, dwell time). The sintering behavior of the zirconia powder is therefore identical whether it is carried out in microwave or conventional sintering. Consequently, even if the cycles used are much shorter, the use of the microwave process makes it possible to obtain microstructures comparable to those observed for samples sintered by conventional means.

A connected technology

Are you mobile ? Zircoya is too !To adapt to new uses, you can launch your cooking remotely via a tablet. The intuitive interface allows you to choose :

  • the zirconia block
  • the type of prosthesis
  • the teeth involved

Based on this information, the app detects the right sintering cycle and you just have to program the cooking.

“Ding !” : do not wait in front of the oven, a notification will notify you as soon as the cycle is finished.

Because projects and types of zirconia evolve, our team works to create specific sintering cycles on a regular basis to adapt to all situations.

In addition to cooking cycles, Zircoya facilitates your day-to-day management. Quality, traceability, production order or even commercial monitoring… find your entire activity in a single interface.

Launch of remote cooking

Pre-programmed and adapted thermal cycles

Traceability of your sintering cycles

An application available on tablet and smartphone

… What if you can find your smile back with Zircoya ?
