Types of dental impression

Dental resin printer

Resin dental printing is the most common among dental practices and clinics.
Usually the production rate will be higher when there are high quantities, the printer works so that the UV irradiation on the whole layer goes up and down and the process repeats itself.
So that if there is one product or 10 products in the same tray, the printing time is the same, that is, the time is according to the height of the Z axis only.

Types of liquid dental impressions:

Models – there are several common types such as: a model for measuring analogs, irises or a model for whitening – undergo additional processes of vacuum forming, surgical splints and more.
An example of such materials:
The best Phrozen Dental Model – a little more expensive but stronger and more reliable
The most common P hrozen water washable gray – cheaper and works for the vacuum forming process (common for irises)
Accurate and comfortable shade Resin Phrozen3d 4K aqua ivory – comfortable to model for analog measurement.

Temporary or permanent crowns – all materials in general are FDA / CE Class II that are officially valid in Israel for 29 days, to get approval for a permanent Class III (even in the event that something like this has to be provided) it is very complex in Israel requires a clean room very strict standards and a mother’s approval “R.
Unauthorized materials can indeed leave you open to unnecessary lawsuits.
We stock 2 materials – Enlighten AA temp is considered temporary ( class II approval ) , P CROWN – considered permanent (class II approval) but much more expensive.
The materials are usually thick, it is recommended to heat the chamber during printing (you can also heat the bottle before) in our materials no special UV or nitrogen is required.
In 3D you can do things that are not possible with a lathe, but usually the printing is a little weaker.

Wire FDM printer

The best-selling printer in the FDM wire category is Bambulab, winner of the Best inventions award

Meets the needs of the dental industry regarding models and not temporary or permanent.
To the best of our knowledge, there is no FDA or CE class II approved filament, there is a lot of class I intended for medical devices and not for temporary crowns.
The method is more convenient than liquid printing because there are no accompanying processes such as washing with alcohol, drying and UV hardening.
When high accuracy is required, it is recommended to make several changes to the printer and the slicer software.

The types of models that can be made with wire printing:

Teeth whitening – there are a number of doctors who prepare models and they go through another process of vacuum forming .
Analogues – preparing a model for checking dimensions according to execution
Iris – it is possible to make recommended irises from a more durable material than PLA PRO because they go through an additional process of vacuum forming .

In conclusion

Dental printing for higher working scopes a liquid printer is recommended, in clinics a liquid printer is not always convenient because there are many processes and there is a strong smell and it is not always possible in the clinic.
There is a lot of work in Israel in dental laboratories, almost all of them are digital, some of them have over 5 3D printers due to the need for a large number of models (mainly irises)
