  • Space closure and deep bite correction were smooth in this case due to good bite control with precision bite ramps and excellent patient compliance.
  • Class II elastics were used to aid in upper canine extrusion and Class II correction.
  • Aligners were changed every 5 days with the combined use of OrthoPulse accelerator. Therefore the treatment was completed in a relatively short period of time.
