Interceptive treatment carried out with removable appliances at the correct time may save the patient from a more complicated treatment at later stage.
Early orthodontic treatment will not resolve all potential orthodontic problems or totally inhibit adverse skeletal growth patterns. However, by identifying problems at an early stage it is possible to redirect skeletal growth, improve the occlusal relationship, enhance the patient's esthetics and self-image and, perhaps of even greater importance, achieve results that are unattainable later with the eruption of the teeth and the cessation of growth.


To reduce orthodontic treatment procedure in the late childhood it is sometimes necessary to treat dental malocclusions in early childhood. Therefore interceptive orthodontic treatment with removable appliances has proved its success in special indicated cases such as an unilateral buccal crossbite with displacement of the mandible, skeletal Class III relationship with anterior crossbite and the serial extraction therapy. We want to share our experiences and we present three representative cases of interceptive orthodontic treatment in early childhood.



7 year old girl with an anterior crossbite of the teeth 11/41, Class I malocclusion and a mild skeletal Class III pattern.


The patient was treated with a Fränkel III regulator. After 3 months the anterior crossbite was corrected. The appliance was used as a retainer for 18 months until all front teeth showed a correct overbite. The overjet and the overbite were successfully improved. No other retention was needed.

5 ½ year old boy suffered of a laterognathia due to an unknown collum dysplasia of the right condyle with a shift of the mandible to the left, a midline discrepancy and a tilt occlussal plane to the left. The mobility of the mandible was normally.


An avtivator was inserted for 12 months. A constructive bite was taken, bringing the jaw to the midline. The appliance was used to guide the eruption of the first molars while different growth at the condyles corrects the asymmetry.
The occlusal plane was leveled and the mandibular displacement was improved. Additionly an appliance with posterior bite blocks for the vertikal dimension was inserted for further 6 months.

5 ½ year old girl with an unilateral buccal crossbite with mandibular displacement to the left, a reduced width of the maxilla and a mild Class III pattern.


We inserted a removable appliance with a midline screw and posterior bite blocks. The maxillary arch was expanded bilaterally for 2,5 mm. The mandible displacement was improved and the occlusion was stable after 5 months.
The bite blocks were removed. The appliance was used as a retainer for further 6 months.

Early therapy by using removable appliances can reduce dental and skeletal malocclusions in the late childhood. Therefore we recommend the interceptive orthodontic therapy as a short and temporary limited intervention and we think that there is still a need for interceptive treatment.
