- The K3 focuses on final alignment of the teeth while retaining the arch form, breathing and myofunctional habits. - It is the firmest appliance in the series, designed to provide the best retention of arch form and habits. - By this stage of treatment, patients' teeth will be mostly aligned and, therefore, the K3 can be used to finalise any remaining mild malocclusion. - Move to the Myobrace for Teens series if further treatment or retention is required in the developing permanent dentition. **For further product information, please contact Chat Support**
