Orthodontic Palatal Expander

Clinical Presentation: Patients presenting with dental crowding, crossbite, or narrow jaw arches may be candidates for palatal expansion.

Oral Health Status: To support the outcome of treatment and minimise the risk of complications, it is essential that the patient has healthy teeth and gums. Existing dental concerns must be managed prior to commencing expansion.

Jaw Structure: An orthodontic assessment will evaluate the patient’s jaw structure to determine if expansion is feasible without surgical intervention.

Airway Function: Palatal expansion can increase the volume of the nasal airway. This may assist in the management of symptoms associated with sleep-disordered breathing.

Invisalign Clear Aligner Palatal Expanders: These appliances integrate expansion with clear aligner therapy (such as Invisalign). As a removable option, they allow for standard brushing and flossing routines. However, strict adherence to wear-time guidelines is required to progress with treatment.

Rapid Maxillary Expansion (RME) Appliance: The RME is a fixed appliance commonly utilised for patients requiring significant expansion. It involves a screw mechanism that is adjusted to widen the arch. Following the active expansion phase, the device generally remains in place for several months to allow the newly formed bone to stabilise.

Quad Helix Appliance: This device utilises specific springs and helices anchored to the molars. It is typically recommended for patients presenting with mild to moderate crowding who require expansion of both the front and back of the dental arch.

Removable Palate Expander: A custom-made plate that can be removed by the patient. This is often prescribed for cases requiring limited expansion. While the removable design facilitates oral hygiene, the appliance must be worn consistently as directed to support treatment outcomes.

Surgically Assisted Rapid Palate Expander (SARPE): SARPE may be indicated for adult patients where the jawbone has fully matured and fused. This approach combines orthodontic treatment with a surgical procedure to release the bone structures, facilitating the widening of the upper jaw.
