Tongue Blade

Tongue blade therapy is used to treat the developing incisor crossbite by placing the wooden tongue blade behind the tooth in crossbite at an angle of about 60 degrees to the occlusal plane. The patient should exert force by biting on it using the lower teeth as a fulcrum for 5-10 minutes. Usually, the tooth will erupt into a normal position over some time.

Catalan’s Appliance or Lower Anterior Inclined Plane

• Catalan’s appliance is also called a “lower anterior inclined plane,” which explains the design of this appliance. Catalan’s appliance consists of an inclined plane cemented to the lower incisor.
• Fabrication
  • Acrylic resin or cast metal is used to fabricate Catalan’s appliances. The lower anterior inclined plane is designed in such a way that it is at45-degreee angle to the maxillary occlusal plane. Ctalan’s appliance can be fabricated on a single lower anterior tooth for the correction of single tooth crossbite or the whole anterior segment.

Removable Orthodontic Appliances

• Removable orthodontic appliances in case of single tooth incisor crossbite, “Z” spring on the tooth involved in crossbite can be used for correction of such a condition.
• Removable orthodontic appliances with expansion screw:
• Removable orthodontic appliance incorporates expansion screws of various types, which can be used to correct single incisor ccrossbites

Correction of Incisor Crossbite in Adolescent and Adults

Removable orthodontic appliance incorporated expansion screw of either mini or medium, which may also be used to correct anterior crossbite involving single tooth in adults.

• Removable Orthodontic Appliances
  • Removable orthodontic appliances with mini screw:
    • Removable orthodontic appliance with incorporated mini screw type of expansion screw, which is used to correct the anterior crossbite involving single to two teeth in crossbite.
• Fixed Orthodontic Appliances
  • Fixed orthodontic appliance can be used to correct incisor crossbite involving an ingle tooth.
  • The in-locked teeth are pulled into their correct labial position by fixed appliances.
