With this new product, the initial stability is effectively improved by increasing the taper Body. ● When the approach is difficult due to the narrow space between Therefore, sufficient final torque for placement and less the possibility dental roots of the maxillary/mandibular anterior teeth of displacement ∅1.4 can be achieved when applied with orthodontic ※ The ∅1.4 force. size has limited strength due to its small size. Pilot drill placement is recommended to prevent fracture. 50 Resistance against Orthodontic Forces Resistance of the thread against external load To use orthodontic screws as a stable anchorage, the screw thread 30 and bone must have sufficient resistance against orthodontic forces.
