Market demand

The dental industry is mainly driven by three aspects:

  • First class quality

  • Cost effectiveness

  • Availability

While most OEMs aim for the longest possible product life in order to secure their market position and reputation, there are regions in the world where customers still require a quality product, but the price is absolutely paramount. In the spare parts market, the availability of quality products is the most important factor. None of the above requirements is more important than any other.

The key is to understand and be prepared for the specific needs. In addition, each region has its own market characteristics that determine both OEM and aftermarket requirements.

A typical reference would be “EL 740 Z”, which would be an elemental bearing with a covered side, steel balls, steel cage, P25 radial clearance and oil.

Special materials for special products

Developing the basis for a precision product

Special requirements apply to the materials used in a dental instrument.

  • Structural strength

  • Abrasion resistance

  • Autoclave resistance


For the production of our bearings, we use the most widely used rolling bearing steels. However, we purchase them with our own specifications in order to achieve a fine-grained structure and maximum hardness. In addition, the MinebeaMitsumi Group has developed nitrogen-alloyed steels that can be used to achieve even higher corrosion resistance.

We use only the highest-precision industrially manufactured balls available on the market. You have the choice between balls made of 440C corrosion-resistant steel or ceramic.

myonic offers a variety of cage materials suitable for a wide range of markets. The standard material is phenolic resin, which has proven itself on the market for many years and is widely used.

is our highest-quality cage material. Our exclusive PI formulation outperforms all other known cage materials on the market.

In addition to the well-known and proven greases used in dental technology, myonic has successfully developed and uses its own high-speed dental greases. If required, even lubricants with H1 approval are available.

Some of the above materials are only available from the MinebeaMitsumi Group due to exclusivity agreements with material suppliers. With ongoing development programmes, we ensure the continuous further development of our products and processes.

Dental spindles

The function of the spindle (Also known as the collet chuck) is to hold the tool, drill or milling cutter securely during operation and to guide it precisely.

Major challenges include tens of thousands of opening operations, corrosion caused by water or aggressive media and high speed.

The durability of this component is the most important factor for patient safety.


Turbine units

The myonic collet offers the unique possibility of perfectly pairing the high-speed bearings established over decades with the adjacent component.

In combination with the rotor, which is also manufactured in-house by myonic, the result is an ideally matched turbine unit that can be installed in the instrument without any further adjustments.



The extreme conditions myonic bearings have to withstand in operation require the most ideal environment possible.

Despite a precisely manufactured instrument housing, it is necessary to protect the bearings from being overloaded or having excessive clearance. For this purpose, myonic offers the appropriate accessories such as shims and spring washers, snap rings and bushings for ideal assembly.

Information from our customers

“Exceptional Supplier 2022” at Dentsply Sirona

The “Dentsply Sirona Global Supplier Forum 2022” – a high-caliber supplier conference – was held virtually for the second time in May. Dentsply Sirona Inc. was formed in February 2016 through the merger of DENTSPLY International (USA) and Sirona Dental Systems (DE) and has since become the world’s largest manufacturer of dental products and technology with a turnover of over 4.25 billion dollars/year and is also one of our main customers.

At the event, Dentsply Sirona’s managers gave their presentations online to more than 200 top suppliers, who were connected worldwide via their computers. In 2021, Dentsply Sirona introduced its new “Supplier Awards Program for Exceptional Partners”.
All suppliers have the opportunity to participate in this competition.

The criteria for the award program are based on Dentsply Sirona’s procurement goals: sustainability, quality, delivery performance, innovation, partnership and diversity.

Intensive collaboration has paid off
For the application, myonic worked intensively with the responsible purchaser for several months in order to submit all the required documents on time.
Out of around 12,000 suppliers, only 70 companies were nominated for the title of “Exceptional Supplier Partner”, of which only one was ultimately awarded in each of the seven product groups for “Direct Material”.
myonic was honored in the “Rest of Spend” category, which primarily includes steels and products made of metal, such as bearings.

Award for exceptional performance
In his video message, the responsible director, Todd Dunn, emphasized not only the outstanding delivery and quality performance, but also the very good development partnership between our companies. Our clear concept of becoming climate-neutral by 2030 was particularly emphasized!

It was even nicer to receive the award personally from the Dentsply Sirona team a few months later.

We would like to express our sincere thanks for the many years of successful and good cooperation!
