Bonded Palatal Expander

The bonded palatal expander consists of a clear acrylic bite molded onto a baby’s baby teeth and an expansion mechanism located at the midline of the palate, the top of the mouth. Connected via a palatal bar, the headband tube and/or traction hook can be incorporated in order to allow the bonded palatal expander to be worn with a suitable headband. Thus, it plays a corrective role.

It is commonly used in young patients with a mix of baby and permanent teeth to solve problems such as crowded teeth and malocclusions. In the early stages of wearing, patients may experience discomfort. But it will return to normal after a while. During wearing, be careful to avoid eating sticky/chewy foods. In addition, in order to maintain the dilator, it is recommended that patients wash it with water after eating, especially around the strap, the dilator, and the palatine bar.
