Beautifully Fine BioHpp Crown Gracefully Delicate Currency

Processing steps

Initial situation

In order to provide optimum support to the framework structure, a casement or level preparation is required. We do not recommend any tangential preparations.

Modelling

The objects are modelled in accordance with the standard dental technical rules. In order to guarantee a mechanical bond between BioHPP and veneer composites, retention crystals can be used.

Sprue technology

In order to be able to achieve perfect pressing results, certain regularities such as selection of the supply channel, cross-care and positioning must be observed.

Investment

The wax model is invested with a special phosphate-bound investment material - taking into consideration the fluid concentration.

Pre-heating

The pre-heating process, for melting the wax and controlling expansion of the investment material, is carried out in the laboratory's own pre-heating oven (between 630°C and 850°C).

Melting

The melting procedure is carried out in the preheating oven. For this, the melting temperature of 400°C (20 min. and not longer) must be observed exactly and controlled.

Pressing

The pressing procedure in the for 2 press system is completed fully automatically within 35 minutes.

The dental technician is informed of the end of the automatic pressing procedure by an acoustic signal and by the blue LED light. The technician can then continue the process by immediately devesting the mould.

What makes the for 2 press system special is the fact that the pressing procedure is also continued when cooling the mould. This principle ensures the high material properties of the BioHPP, which are transferred into later treatment.

Devesting

The object transferred in BioHPP can be devested after 35 minutes. A short water bath guarantees freedom from dust and makes the devesting process easier. The fi ne investment material residues are removed using a fi ne blasting device with aluminium oxide with 110 µm max. 3 bar.

Adjustment

The simplicity of the adjustment is due to the material and reduces the need for time-consuming reworking. Fine cross-toothed carbide mills are particularly well suited to this.

Conditioning

The bridge framework is blasted with 110 µm and 2-3 bar pressure. The blasting distance must not be less than 3 cm.

In order to achieve a suffi cient adhesion between veneer composites and framework material, a special adhesive (visio.link) must be used.

Veneering

Framework structures made from BioHPP can be veneered with all traditional veneer composites. The best results are achieved with visio.lign.

Polishing

The veneer composite and the BioHPP can be polished to a high shine, by following the correct polishing sequence.

High-shine polishing

Due to perfect high-shine polishing (fi ve steps), the material properties of BioHPP with regard to plaque affi nity, tendency to discolouration and surface quality are supported.
