The pioneer in preparation technique

The company was founded in Berlin on August 1st, 1920 by Wilhelm Hugo Drendel and Fritz Zweiling. 
During the first years, Drendel + Zweiling focused on the production and distribution of special dental instruments. 
However, it was not long before the company started intense research into the production of diamond instruments.

With the invention of the galvanic coating process in 1932, Drendel + Zweiling’s constant strive for improvement was crowned with success. Drendel + Zweiling became a pioneer in the production of advanced dental diamond instruments.

Further milestones in the development of dentistry:

Drendel + Zweiling has always been customer orientated and therefore constantly extended their range for the dental practice and laboratory.

Today, the instrument range includes the following products: 
• diamond instruments and discs
• tungsten carbide burs and finishers
• surgical instruments
• ceramic abrasives
• polishers
• instrument sets
• bur blocks
• diamond coated forceps
• instruments for ENT and neurosurgery
