Abstract

Background

Clear aligner therapy has emerged as a popular alternative to conventional fixed appliances due to its esthetic appeal, comfort, and ability to maintain oral hygiene. Although traditionally limited to mild or moderate cases, advances in digital planning and biomechanics have extended its application to more complex malocclusions.

Case Presentation

This report describes the non-extraction management of a 20-year-old female patient presenting with Class II Division I malocclusion, upper anterior proclination, and moderate crowding in the maxillary arch. Treatment was carried out using ClearPath® aligners over a period of ten months. Interproximal reduction (IPR), attachments, and controlled arch expansion were incorporated to achieve desired tooth movements. Periodontal health and aligner fit were regularly assessed, both of which remained satisfactory throughout the course of treatment.

Results

At the end of therapy, the patient achieved proper overjet and overbite, improved lip posture, and well-aligned maxillary and mandibular arches. Dental crowding was successfully resolved, with stable occlusion and no adverse periodontal effects.

Conclusion

Clear Path® aligners, when combined with precise digital planning, IPR, and attachments, can effectively manage selected Class II Division I malocclusions without extractions. This case highlights the potential of clear aligner systems as a viable esthetic and functional treatment modality in suitable patients.
