Which appliance is required for treatment of the crossbite?

• A. Removable appliance with inclined plane
• B. Removable orthodontic apparatus of mechanical action
• C. Fixed orthodontic appliance
• D. Bionator Balters tip ΙІІ

Answer: (A)

The main idea is that a simple, removable appliance with an inclined plane can directly correct a mild crossbite by guiding tooth movement when the patient bites down. The inclined plane creates a disoccluding contact that induces controlled tipping of the teeth on the crossbite side, typically moving the upper teeth buccally (or the lower teeth lingually) to align the arches. This approach is especially appropriate for growing patients with a unilateral posterior crossbite because it is easy to fabricate, adjustable, and relies on the patient’s bite to drive the correction without the need for fixed braces. Other options either target different problems or require more invasive or comprehensive mechanics. A fixed appliance is powerful for dental alignment but isn’t needed for a simple crossbite in a growing patient. A functional appliance like the Bionator Balters tip III focuses more on jaw relationship than on direct crossbite correction, and a removable apparatus of mechanical action isn’t as specifically equipped to produce the focused tipping achieved with an inclined plane.
