# Early Intervention in Class II Division 1 Malocclusion Using an Activator Appliance: A Case Study

## TL;DR

This case study explores using an activator appliance for early orthodontic treatment of a Class II malocclusion, avoiding tooth extractions.

## Contribution

The study presents a non-extraction treatment approach for Class II Division 1 malocclusion using myofunctional appliances.

## Key findings

- Early intervention with an activator appliance can correct skeletal Class II malocclusion without extractions.
- Myofunctional appliances are effective for treating Class II Division 1 malocclusion due to mandibular retrusion.

## Abstract

The field of orthodontics has traditionally been regarded as the primary specialty within dentistry. As per Dr. Tweed's recommendation, historical treatment approaches often entailed the extraction of four premolar teeth. Nonetheless, early orthodontic intervention can frequently obviate the necessity for extractions, thus preserving the integrity, functionality, and aesthetic appeal of the dentition. This case report details a non-extraction approach for managing a developing skeletal Class II malocclusion, characterized by a skeletal disharmony between the maxilla and mandible. The chosen treatment option is influenced by factors such as the patient's age, growth potential, the severity of the malocclusion, and the patient's adherence to the prescribed treatment regimen. Myofunctional appliances have been identified as effective in addressing Class II Division 1 malocclusion resulting from mandibular retrusion.
