Hawley with jackscrew and quad-helix/w-arch appliances are commonly used to treat mild posterior crossbites. These appliances can help in expanding the upper dental arch to correct the misalignment of the teeth and achieve a more balanced bite relationship.

Regarding the other options:

- Severe posterior crossbites are usually treated with more aggressive treatment options such as rapid maxillary expansion or orthognathic surgery.

- Anterior open bites often require different types of appliances or treatment modalities to address the specific nature of the malocclusion.

- Class 3 malocclusions are typically treated with a combination of orthodontic treatment and/or orthognathic surgery, depending on the severity of the malocclusion.
