3M Unitek Forsus Fatigue Resistant Device EZ2 Module streamlines installation with its consistent design, preventing spring pivoting towards the cheek and featuring marked indicators for easy left and right side identification. Tailored for compatibility with 3M Unitek Buccal Tubes, it necessitates an occlusal headgear tube measuring 3.6 - 4.3 mm. Installation is straightforward: clear the headgear tube, insert the clip with Weingart utility pliers until it securely clicks into place, and confirm engagement with a light tug. Removal involves compressing the spring, separating the spring assembly from the push rod, and using Weingart pliers to gently detach the clip in an occlusal followed by a mesial direction. With its user-friendly features and seamless integration, the EZ2 Module ensures efficient and reliable performance in orthodontic applications.
