Product Description

- Commodity name: Twin Block
Twin Block is a functional bimandibular removable appliance that corrects adolescent skeletal Class II malocclusion (mandibular retraction) and some Class III malocclusion (mandibular protrusion) by changing the mandibular position and stimulating mandibular growth. Its unique "upper and lower jaw linkage" design uses the occlusal slope to guide the mandibular forward or backward movement, promotes jaw reconstruction and occlusal coordination, and is the core solution for early skeletal malocclusion correction, especially suitable for children and adolescents (8-14 years old) in the peak period of growth and development.

Advantages:

1. Highly effective bone correction: for patients in the growth and development period, the bone effect is significant, reducing the need for orthognathic surgery in adulthood.

2. All-weather correction: In addition to eating and brushing teeth, it needs to be worn all day (≥16 hours/day) to continuously stimulate jaw growth.

3. Comfortable and easy to adapt: The split design allows the mandible to move freely, and the initial discomfort is mild (1-2 weeks to adapt).

4. Strong adjustability: By adjusting the bevel angle, adding resin or clasp pressure, personalized correction force control can be achieved.

Indications:

1. Skeletal Class II malocclusion: mandibular retrusion, maxillary protrusion, ANB angle>4°, overjet>5mm.

2. Functional Class III malocclusion: mild mandibular protrusion with maxillary underdevelopment.

3. Deep overbite/open bite: vertical adjustment of posterior teeth eruption through bite pads.

4. Combined treatment: combined with fixed appliances or invisible corrections to complete comprehensive orthodontics.
