This oral screen helps patients to overcome bad habits, thereby preventing various types of dental malocclusion and jaw disorders which might otherwise necessitate later orthodontic treatment. Thumb-sucking frequently produces large overbite of the anterior teeth, or deteriorates an existing retroposition of the mandible. In this case the oral screen with a bite cap is indicated. The bite cap prevents the oral screen from tipping. The mandible is simultaneously guided forward. Kid-friendly packaging in a colourful hygiene box. Size I (red ring) for primary dentition, size II (blue ring) for mixed dentition.
