– The use of OrthoPulse® allowed for faster aligner change rates compared to conventional protocol 7
– Two long-distance OrthoPulse® patients, unable to attend frequent and regular appointments, were able to complete treatment more quickly than anticipated8
– A patient using OrthoPulse® changed aligners every three days throughout treatment and achieved successful results9
