The Forsus™ Fatigue Resistant Device is the optimal solution for Class II Correction, the automatic, hygienic & comfortable way to continuously apply light force.


Class II Correction is a common orthodontic case requirement. The options for Class II treatment have traditionally presented a difficult decision. Choices were limited to fixed intraoral devices with known breakage concerns, or other appliances – including headgear – that require patient compliance.

The Forsus™ Fatigue Resistant Device, now with more than ten years of clinical use and over one million patients treated, overcomes these concerns and limitations.

Increased Versatility with Three Installation Options

Forsus™ L-pin Module

The L-pin module allows for more flexible installation options and movement in the mouth. It can be used with a gingival or occlusal headgear tube. The left and right sides are universal. It is also used with the Forsus™ Wire Mount, permitting installation without a molar tube.

Forsus™ Fatigue Resistant Device EZ2 Module

The EZ2 module allows for more consistent installation and automatically prevents the spring from pivoting toward the cheek. The EZ2 module can be used only with an occlusal headgear tube and has permanently marked indicators for the left and right sides.

Forsus™ Wire Mount

The Forsus™ Wire Mount slides onto the archwire and provides an attachment option for the L-pin Spring Module, thus eliminating the need for molar bands and making it easier to incorporate the Forsus Device mid-treatment.
