MOBILE AND FUNCTIONAL DENTAL APPLIANCES
These customized appliances, made in the dental laboratory based on a previously made impression of the dental arches, correct simple or medium dental anomalies, by exerting controlled pressure on teeth and jawbones.
Mobile appliances are recommended to children with the request of being worn during both day and night, except for meals and tooth brushing. They are used for a short period, as part of a broader treatment plan.

What are they made of?
- The acrylic resin frameworkis the base of the appliance, the part holding the screws and springs, and gives stability to the whole structure. It is made in the lab and can be colored, with a print or glittery.
- The Clasp is the anchoring element, which is fixed on molars or premolars. There are more types of clasps, depending on the type of dental appliance. The clasp ensures the immobility of the appliance.
- The springshave the role of moving the teeth in the wanted direction.
- The screw is the active element and helps expand the arches. It is activated by the dentist in the office or by the patient himself, at home, using a special key.
