Abstract
Background/purpose: Class III malocclusion with anterior crossbite in primary dentition may progress and complicate future orthodontic treatment. This short communication presents preliminary clinical observations of very early interception using a prefabricated functional education appliance.
Materials and methods: Three children aged 4 to 6 years with dental, functional, or mild skeletal class III malocclusion were treated using a prefabricated removable functional education appliance worn at night, with regular follow-up.
Results: In the dental class III case, anterior crossbite was corrected within 9 months and remained stable at the 2-year follow-up. In the functional class III case, anterior crossbite and mandibular shift were corrected within 5 months, with stable occlusal development at 18 months. In the mild skeletal class III case, negative overjet improved to positive overjet within 9 months.
Conclusion: Very early interception using this appliance may be a practical, non-invasive option for selected young children during primary dentition management
