Yorumlar

  • The condition of the patient's lower posterior teethindicated that this patient would benefit from occlusal restoration
  • We divided the orthodontic treatment into three steps:
  • Step 1: The extraction of 1.4,2.4, finishing the buccal occlusion in Class I canine relationship and Class II molar relationship, retracting the anterior teeth and improving lip protrusion.
  • Besides maintaining the height of the upper anterior teeth and intruding the lower anterior, to correct the deep bite of the anterior teeth.
  • Step 2: Establishing a normal overbite with posterior teeth occlusal restoration
  • Step 3: finalizing the treatment
  • Successes during this treatment
  • We closed the extraction spaces with the use of the maximum anchorage attachments utilizing the G6 protocol only, no Class II elastics, no micro-screw implant
  • Lower anterior teeth intrusion achieved which treated the overbite successfully within the initial aligner phase
  • Improvement points
  • There has been a significant loss of torque of the maxillary incisors in the initial aligner phase which we could solve with the use of power ridges in the Additional aligner phase
  • Posterior occlusal restoration could have been done better which resulted in a deeper bite then we planned. The patient lived in another city and this conflicted with the treatment plan.
  • Conclusion
  • This case provided us more confidence in the Invisalign G6 system
  • Overall treatment results are very satisfying
