Zirconium oxide structures
Prostheses with ceramic-coated surfaces are among the most aesthetic and realistic-looking. The production of such prostheses usually consists of two stages:
1. Formation of the framework, which provides strength to the prosthesis.
2. Application of 3 to 18 layers of ceramic to the surface of the framework, making the prosthesis visually indistinguishable from a natural tooth.
The framework can be made in various ways from cobalt-chromium alloys (metallic), or it can be metal-free. There are several materials that can substitute metal in the creation of the framework. Mostly, this is pressed ceramic or zirconium dioxide.
We mill the zirconium dioxide framework in our digital milling center using the CORiTEC 150i PRO. We use Aidite material.
Ideal aesthetics, stability, biocompatibility, and durability of fixed dental prostheses.
During milling, the framework is produced with a volume approximately 15% larger than the final volume of the prosthesis. This is because after milling, the ZrO2 framework is sintered in the Mihm-Vogt Tabeo-2/M/Zirkon-120 furnace to gain strength and color. During this process, the framework proportionally shrinks.
You can learn about the production of frameworks made from pressed ceramics on the page of the corresponding department.
The time required for milling a zirconium dioxide framework is approximately comparable to the milling time of Ivoclar IPS e.max CAD, but significantly faster than the pressing of IPS e.max Press.
Once the framework is ready, the stage of multi-layer ceramic application on its surface begins. This helps to achieve natural color transitions and translucency at the cutting edge of the final prosthesis, resembling natural teeth. The exception is “full anatomy”.
In this case, to reduce cost and speed up the prosthesis production process, no additional ceramic layers are applied to the ceramic framework. The prosthesis is, therefore, of a uniform color.
For milling the “full anatomy” cercon, we use Aidite Multilayer-3D discs. To give color shades to the full anatomical prosthesis, its surface is impregnated with special solutions before sintering.
For frames for application, we use Aidite SHTC discs.

When covering the framework with IPS e.max Ceram ceramic, each layer is successively baked in the Programat P310/G2 or Vita Vacuumat 30 furnace, which raises and lowers the temperature according to a precise formula.

For metal-free ceramic work, it is possible to add an artificial gum – “pink aesthetics”. Pink aesthetics is created by the technician from IPS e.max Ceram Gingiva ceramics simultaneously with the application of surface layers of ceramics.

We accept intraoral scans, dental impressions, plaster models, and STL files. The STL file implies a ready-to-send model that does not require modeling by our technicians.
The production time depends on the type of model provided. An STL file is the fastest option. All other impressions require modeling before production. The plaster model and dental impression, unlike the intraoral scan, need to be digitized. The dental impression will need to be cast in plaster beforehand.
The time required for milling the framework primarily depends on the availability of a prepared STL model for our equipment. If the model is available, milling up to 5 units will take 24 hours, and for more than 5 units, it will take 48 hours.
If we need to prepare the impression for milling ourselves, the timelines will increase to 5 and 14 days, respectively.
The application of IPS e.max ceramics to the zirconium dioxide framework will require up to 7 more days.
