The quattro-System

For unlimited possibilities

The use of mini-anchor screws has become increasingly common in orthodontic practice over the past 20 years. As one of the first systems for skeletal anchorage, our quattro system has set standards in this respect: Extremely versatile in application and continuously developed, it offers orthodontists all over the world a wide range of options for reliable anchorage of orthodontic appliances.

One of the first and now most widely used screws – the quattro screw – has been continuously developed and optimized for all common applications thanks to the hook shape and the quattro bracket head. With the quattro mini screw a new even smaller bracket head design is launched. The quattro mini screw opens up a new dimension in patient comfort, optimizing not only the delicate structure but also the product design.
