A 13-year-old patient was referred by her general dentist for orthodontic evaluation due to concerns regarding dental crowding and proclined maxillary incisors. Initial examination revealed a class II molar relationship bilaterally. The patient presented with moderate crowding, with an arch length discrepancy of -8 mm in the mandibular arch and -5 mm in the maxillary arch. Overjet measured 4 mm, and overbite was 3 mm. The maxillary dental midline was coincident with the facial midline, while the mandibular midline was shifted 2 mm to the right. Proclined maxillary and mandibular incisors, a mandibular Bolton excess, and a mild curve of Spee were noted. Treatment was provided using ClearCorrect® clear aligners (Straumann, clearcorrect.com) without the use of attachments and with class II elastics bilaterally on slits in the aligner. A total of three refinement phases were required to achieve the desired treatment objectives. Over an 11-month treatment period, successful correction of the bilateral class II canine relationship was attained, along with retroclination of the maxillary incisors, improvement of dental alignment, and leveling of the curve of Spee. The final result demonstrated improved occlusion, esthetics, and functional stability while maintaining periodontal health.
KEY TAKEAWAYS
- Removeable ClearCorrect clear aligners allow patients to eat, drink, and take care of their teeth in a normal fashion. Moreover, patients can wear or remove the aligners throughout daily activities without added risk of irritation or injury.
- ClearCorrect aligners are designed to provide improved leverage to move teeth, which may result in fewer, or no, attachments being used. Treatment in this case was provided without the use of attachments.
- Desired treatment objectives were achieved in this case in three refinement phases over 11 months, successfully correcting the bilateral class II canine relationship, retroclination of the maxillary incisors, dental alignment, and leveling of the curve of Spee.
