Types of Orthopedic Appliances

Orthodontic Expander

Dentofacial Orthopedic Appliances
If your child begins orthodontic treatment before all adult teeth have erupted, it is known as Phase One treatment. During this phase, your orthodontist will use treatments designed to correct your child’s jaw growth and make sure that the jaw bone is properly aligned.

The palatal expander expands (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent relapse.

Your orthodontist will instruct you about when and how to adjust your expander. These fixed expanders utilize expansion screws as the mechanism providing force to widen the jaw. These appliances have expansion screws which are adjusted by a special expansion screw key.


Distalizing Appliances: Pendulum/Pendex

The pendulum is designed to provide consistent and dependable upper molar distalization (to push back) and rotation without the need for patient cooperation. The pendex design is similar in nature to the pendulum but incorporates an expansion screw in the design to allow for both molar distalization and expansion.

Space maintainers, such as the lower lingual arch or an upper space maintainer such as a nance, are used to prevent medial molar drift during the mixed dentition phase. These appliances aid in space preservation and unraveling between baby and adult teeth.
