A female presented in her early twenties with concerns about the movement of her upper anterior teeth and increasing crowding. The patient presented with Class II division I malocclusion on a Class II skeletal base with an increased overjet, mild upper and lower crowding and deviated upper and lower centre lines. Her oral hygiene was good, though she is a smoker and had a history of taking medication for depression (Fluoxetene).
The patient worked in a public facing role, and was therefore interested in a discreet solution that could solve the problem without being unsightly. Suitability was therefore assessed for treatment with the clear aligners.
|Lower Face Height||Lower|
|Soft Tissues||Nothing abnormal|
|Overjet||<6mm with proclined upper central incisors|
|Displacement on Closure||None|
|Incisor Relationship||Class II Division I|
|Molar Relationship||Left: Class I | Right: Class I|
|Canine Relationship||Right: Class II ½ | Left: Class I|
|Teeth Present||7654321 | 1234567 | 7654321 | 1234567|
|Centrelines||Upper centre line deviated to the left 1mm | Lower centre line deviated to the right 3mm|
Photographs and impressions were taken and the Archwize™ digital planning software was used to confirm suitability for treatment with the ClearSmile Aligner. An estimated 1.0mm of interproximal reduction (IPR) would be needed in the maxilla and 1.2mm in the mandible. Tooth whitening was also proposed to complete treatment following alignment. Digital 3D models were created to demonstrate to the patient what could be achieved. With informed consent, we were able to proceed.
- Class II skeletal pattern
- Proclined upper central incisors
- Crowding on the left hand side of both upper and lower arches
- Deviated upper and lower centre lines
- Class II canine relationship on right hand side
- Increased overjet
Ideal treatment aims:
- Correct the skeletal pattern
- Align upper and lower arches
- Align centre lines
- Align incisors and right hand side canines to Class I occlusion
Compromised treatment aims:
- Align upper and lower anterior segments
- Accept deviated centrelines
- Accept canine relationship

|January 17||Course of treatment finished, however, UL2 could use more rotation – further Clear Aligners suggested. Patient accepted. Composite drivers removed. Photos taken. Whitening gel supplied and first of additional aligners fitted.|
|March 17||Retraction and isolation. IPR performed with 0.2mm diamond strips on the UR2, UL2 and with 0.3mm strips on the UL1, UR1 and UL3 contact points. Photos taken, impressions for upper retainers taken.|
|June 17||Patient happy with appearance of uppers. LL3 position discussed – more aligners suggested. Patient accepted. Upper and lower impressions taken and sent to the IAS lab. Additional lower aligner fitted.|
|August 17||IPR performed with 0.2mm blue diamond strip on LL2, second additional lower aligner fitted.|
|September 17||Patient happy with outcome so result acceptance form completed. Impression taken for lower retainer and results sent to the IAS lab.|
The IAS Academy instructors offered support through multiple stages of the treatment via the online forum. By posting impressions and photographs I was able to benefit from the advice of the experts and other professionals, helping to achieve the best end results.
Upon reflection, the LL3 would have benefitted with further correction earlier in the treatment process. I only discussed this with the patient at the completion of the upper arch, which delayed treatment slightly following occasional missed appointments. However, treatment with clear aligners fully met the patient’s expectations, achieving a smile she was happy with by using a minimally invasive technique.
