Processing routes of dental polymers

What are the different processing routes of dental polymers?

There are three common processing routes for dental polymers: injection molding, CAD/CAM (computer-aided design/computer-aided manufacturing) and 3D printing.

What is injection molding?

In injection molding, liquid polymer is injected into a special mold and kept under pressure until it has cured. This process enables the mass production of dental products with high precision and reproducibility.

What is CAD/CAM?

CAD/CAM is a computer-aided process that uses software to create a 3D digital model of the desired denture. This model is then sent to a milling machine, which precisely mills the polymer block into the desired shape.

What is 3D printing?

3D printing, also known as additive manufacturing, enables the layer-by-layer production of dental prostheses from dental polymers. The digital 3D model of the denture is sent directly to the 3D printer, which layers the polymer material to produce the desired denture.

Which processing method is best?

The best processing route depends on various factors, including the desired restoration, the complexity of the case and the dentist's preferences. Each processing route has its own merits and may be preferred in certain situations.

What are the advantages of injection molding?

Spritzguss ermöglicht eine hohe Präzision und Qualität des Zahnersatzes. Es eignet sich gut für die Massenproduktion von Zahnersatz und bietet eine breite Palette von Materialoptionen.

What are the advantages of CAD/CAM?

CAD/CAM enables precise and individual adaptation of the dental prosthesis to the specific needs of the patient. It also offers the possibility to visualize the digital model in advance.

What are the advantages of 3D printing?

3D printing offers high design flexibility and enables complex geometric shapes. It is also a faster process compared to conventional methods and can be quickly adapted if necessary.

Are there any disadvantages to the different processing routes?

Each processing route has potential challenges. For example, injection molding requires specialized molds and equipment, while CAD/CAM may require expensive equipment. 3D printing may not be suitable for all types of dental restorations due to material properties.

Who decides which processing route to use?

The decision on the processing route is made jointly between the dentist and the dental technician, based on the individual requirements of the patient and the recommendation of the professional staff.
