Unwanted movement during the molar intrusion need to be controlled.First alignment without the tooth you want to intrude.
After alignment, one arch will be used to make anchorage ( 0.017" X 0,025" SS) and the other to intrude the 1st molar (0,016" Thermal Niti). It's possible because we have a double slot bracket.
Good results after 5 months.
