Comments

  • We aligned the patient's teeth with the help of IPR using proclination and expansion
  • Because the patient didn't agree to extract his wisdom teeth we chose to not distal the molars
  • We controlled the torque with power ridges only which had a great effect on the gumline of anterior incisors. Especially on the 3.1, we saw a huge difference
  • Good treatment outcome without the need for periodontal surgery or extractions
