## TL;DR

This case report shows how orthodontic treatment with miniscrew anchorage improved facial profile and bite in a patient with severe skeletal class II malocclusion.

## Contribution

The study demonstrates the effectiveness of camouflage orthodontics with miniscrew anchorage in treating severe skeletal class II cases without surgery.

## Key findings

- Extraction of first premolars and anterior retraction improved facial profile and occlusion.
- Miniscrew anchorage provided stability and simplified treatment compared to conventional methods.
- Clinical results remained stable for one year post-treatment.

## Abstract

Treatment of severe hyperdivergent skeletal class II protrusion in adult patients has always been a significant clinical challenge for orthodontists. For the optimal enhancement of facial esthetics, orthodontic‐orthognathic treatment may represent the most appropriate treatment option. However, this case report presents the successful camouflage orthodontic treatment of a 25‐year‐old female patient who had a skeletal Class II malocclusion with a convex profile, retrusive mandible, a slight high plane angle of the mandible, individual anterior crossbite, posterior scissor bite, and lip muscle hypertonicity. The treatment plan included extraction of all first premolars and maximum anterior retraction with miniscrew anchorage for optimal profile. The active treatment phase lasted 36 months. Posttreatment evaluation revealed significant improvement in facial profile and optimal occlusal relationship, which demonstrated clinical stability through a 1‐year retention period. This case illustrates that camouflage orthodontic treatment is an effective therapeutic option for adult patients with severe skeletal Class II malocclusion, achieving satisfactory facial esthetics, functional occlusion, and long‐term stability. Miniscrew anchorage additionally simplifies the treatment protocol while avoiding the inconvenience and discomfort associated with conventional anchorage devices.
