Example appliance: Crowded incisors and a deep bite treated with fixed appliances with NiTi arch wires for incisor proclination
Level of evidence: Moderate to high
Suitable for ages: 7+ years old
Indications: Anterior deep bite, normal to retroclined incisors, crowding at incisors, normal incisor display, normal to increased alveolar width, non-extraction treatment, curve of Spee present, normal to hypodivergent skeletal patterns
Contraindications: Hyperdivergent skeletal patterns, proclined incisors, severe over-eruption of incisors, narrow alveolar width, any acquired orthodontic risks
Treatment Objectives and Biomechanics
- Procline incisors (relative intrusion)
- Reduce the overbite
- Level the curve of Spee (mandible)
- Retention plan as incisor proclination alone is usually unstable
Appliances / Treatment modalities
- Fixed appliances
- Clear aligners
- Functional appliances – Herbst appliance etc.
- Auxiliary appliances – incisor bite turbos etc.
