Ratchet wrench driver used with the MSE type-2 expander. Ratchet wrench is designed for a maximum torque of 80Ncm. When greater torque is applied, the instrument is designed to fail, rather than causing TAD failure. The failed driver must then be replaced. Slower movement and regular pauses when inserting TADs are a good practice, as is pre-drilling pilot holes for patients with particularly thick and dense cortical plates. **For further product information, please contact Chat Support**
