Cobalt-chrome for hybrid dental technology

Due to its biocompatibility and excellent machinability, 3D printing with cobalt-chrome is particularly suitable in the field of dentistry. Thanks to laser melting, exactly fitting crowns, bridges or frames for metal-ceramic veneers can be printed patient-specific in a short time. 3D printing with cobalt-chrome also plays a major role in combined dentures.

3D printing for dental technology

3D printing technology has revolutionised many industries and is increasingly finding its way into the field of dental technology. Among other things, patient-specific, physiologically safe and precisely fitting prostheses and bridges can be made from a variety of different materials. The introduction of 3D technologies shortens the process of implant manufacture and significantly reduces material consumption. As an expert with many years of experience in additive manufacturing, FKM is an external service provider for 3D printing orders from diverse industries – from aerospace to dental technology.

Advantages of 3D printing in the field of dental technology

Classically, crowns and other implants are largely created in small-step manual work in dental laboratories. The dental technician works with extreme precision along a plaster cast of the patient’s dentition. The basis of this impression is created in the dental practice.

Nowadays, this is no longer necessarily done using analogue impressions, but with the help of a much more convenient digital mouth scan. A model is created from the data obtained. Once the prosthesis is finished, it is sent back to the dental practice, where the accuracy of the fit is checked. If the superstructure does not fit 100 percent, it has to be reworked. All of this involves a logistical and time-consuming effort for dentist, orthodontist, dental technician and patient. In addition, each individual work step harbours sources of error. This means: the fewer the work steps, the less potential for errors. And this is exactly where the advantages of 3D printing for dental technology come in: the reduction of manufacturing steps with increased precision.

The advantages of the digital production of workpieces for various industries are obvious. In dental technology in particular, production becomes more efficient and the results more precise on the one hand. On the other hand, treatment is also much more pleasant, especially for the patient. There is no longer any need for long and frequent sessions with the dentist. Also, the unpleasant impression of the dentition is no longer necessary. Instead, a mouth scan is taken from the patient and fed into a CAD/CAM programme, where it is prepared for 3D printing. To make the dentures even more lifelike, a facial scanner can also be used. Here, the shape of the patient’s smile is documented. The information is incorporated into the print data. The data acquisition only requires one appointment with the dentist and is done in a few minutes.

The advantages for you at a glance:

  • patient-specific fabrication
  • increased comfort for the patient
  • exact fit
  • hardly any reworking necessary
  • hardly any material waste
  • significantly shorter process times
  • reduced logistics processes

The overall workflow from the digital oral scan to the insertable implant work is significantly faster and more precise thanks to the possibilities of 3D printing in dental technology. Additive manufacturing capabilities are rewarding in many ways. FKM is the ideal partner for dental laboratories when it comes to manufacturing bridges, crowns, partial dentures, abutments, and other dental prosthetics.

FKM: Your expert for 3D printing in dental technology

Where previously the analogue impression had to be sent to the laboratory, now only the print data is transmitted digitally – in this case to FKM as your 3D printing service provider.

Why is it worth leaving the fabrication of abutments and implant superstructures or other dental prostheses to us? FKM has been an expert in the field of additive manufacturing for over 25 years – whether prototyping is commissioned for a product in development, or a customer requires fully operational components for automotive construction or medical technology. FKM Sintertechnik relies on state-of-the-art 3D printing machines and a variety of high-performance materials, depending on the planned area of application. Our employees are experienced and highly skilled in the use of CAD/CAM software, the various raw materials and printing processes. Especially, the acquisition of corresponding equipment for additive manufacturing and the software involve high initial investments that not every dental laboratory can handle. And this is exactly where FKM comes into play. We act as your outsourced dental laboratory regarding 3D printing of implants, crowns, and dentures.

You save the investment costs and do not need space to store the corresponding base materials. Your dental technicians can concentrate fully on completing the superstructures.

The technical possibilities of FKM for precisely fitting dental restorations

In additive manufacturing, there are several process techniques for different materials and uses. Some 3D printing processes, such as laser melting (SLM; selective laser melting), in which FKM is specialised among other things, are suitable for dental technology. In this 3D printing process, the starting material is a metal in powder form. Due to the almost complete freedom of geometry and the possibility of printing filigree structures, the SLM process allows the production of patient-specific and precisely fitting dental prostheses. In general, a 3D-printed object needs to be reworked in order to remove support structures. Objects created in the SLM process tend to have rough inner surfaces. These are smoothed during post-processing.

At FKM, we provide the following post-processing options on request, as we do for all other industries:

  • removal of support structures
  • polishing
  • blasting

The best of 2 worlds

The skills of two experts come together: FKM’s additive manufacturing and the machining post-processing by Henkel Modellbau GmbH with its modern CNC milling machines (Computerized Numerical Control). The post-processing runs with 5-axis milling machines with the highest precision along five different axes at the same time. The aerospace industry in particular uses this technology because very complex parts can be machined. Dental technology also benefits from the time-efficient and precise milling machines in order to optimally smooth the 3D-printed dentures and make them usable. Necessary screw threads are also precisely machined out of the ordered dentures in this manner. Slight tolerance deviations (approximately +/- 0.1 %), which occur with additively manufactured objects, are also compensated for with the 5-axis milling machines from Henkel Modellbau.

Thanks to the cooperation between FKM and Henkel Modellbau, two experts with a 3D technology focus work on the dental prosthesis commissioned by your dental laboratory. However, FKM remains your exclusive contact throughout!

What materials does FKM have available for 3D printing in dental technology?

At FKM, dental technicians can choose from a variety of materials. The materials are biocompatible and approved for the medical and dental technology.

CoCr remanium® star CL

The alloy CoCr remanium® star CL has proven itself in the field of dental technology, as it is biocompatible and toxicologically harmless (confirmed by in-vitro toxicity tests). Thanks to its homogeneous and dense microstructure, the material is ideal for dental restorations of various types.

Titanium Ti64

Titanium Ti64 is a light metal alloy that is both very strong and lightweight. The material is also hypoallergenic and therefore suitable for patients who are allergic to many materials.

Uncomplicated ordering process

You are welcome to order in your preferred way, e.g., simply and quickly via e-mail.
