Growth modification appliances are orthodontic devices designed to influence and guide the growth and development of a child’s or teenager’s jaw and facial structures. These appliances are particularly effective during the growth spurts of adolescence, allowing orthodontists to correct bite issues and jaw discrepancies while the patient is still growing.

Types of Growth Modification Appliances

Functional Appliances: These devices, such as the Herbst and MARA appliances, are used to adjust the relationship between the upper and lower jaws. They work by repositioning the lower jaw or altering muscle function to promote favorable growth patterns.

Expanders: Palatal expanders are used to widen the upper jaw, creating more space for teeth and improving the bite. They are especially useful for correcting crossbites and creating adequate room for permanent teeth.

Headgear: Although less common today, headgear can be used to slow down the growth of the upper jaw or encourage its growth in certain directions, helping to align the bite properly.

Benefits

• Facilitates proper alignment of teeth and development of facial aesthetics.

• By guiding the growth of the jaws and teeth, these appliances help ensure a more harmonious and functional bite, reducing the need for surgical interventions later on.
