Treatment using the Hyrax appliance

The Hyrax appliance is designed to expand the upper jaw, usually in cases of a crossbite (unilateral or bilateral) or insufficient space for the eruption of permanent teeth.

INDICATIONS
Treatment with this appliance is indicated for children and adolescents under 15 years of age. It takes advantage of the opportunity to expand the insufficiently fused bone suture on the palate at this age. Surgical expansion is often necessary at a later age.

FROM CONSULTATION TO APPLIANCE PLACEMENT
Based on consultation, initial examination, and your preferences, we will create a treatment plan. Upon approval of this plan, we will proceed with appliance fabrication in the laboratory based on digital scanning. Appliance fabrication typically takes 3-4 weeks. Appliance placement occurs after teeth cleaning using cement (adhesive). This is followed by an explanation of proper screw manipulation and instruction in dental hygiene. Your cooperation is essential for successful treatment.

PHASES OF TREATMENT WITH THIS APPLIANCE
Treatment with this appliance includes an active phase (when the upper dental arch is expanded) and a passive phase (stabilization, when expansion is stabilized). The active phase usually lasts 2-3 months. During this phase, you will be instructed to turn the screw one turn every other day. Regular appointments for appliance checks during the active phase occur every 3 weeks. If you cannot attend the appointment, it is essential to stop further appliance activation, i.e., stop turning it. Please also contact us as soon as possible to reschedule. The passive phase of treatment follows the active phase, when the upper jaw is adequately expanded. The appliance remains in the mouth during this phase without screw activation. This phase typically lasts 6 months.

APPLIANCE ACTIVATION
We recommend activating the appliance in the evening before bedtime. When activating the appliance by turning the screw using the key, the patient may experience increased sensitivity in the teeth where the appliance is anchored. This is entirely normal and temporary. Pain relievers may also be taken initially.

WHAT NOT TO DO WITH THE APPLIANCE
Since the appliance is securely attached in the mouth for later removal, it is not advisable to consume hard foods whole - for example carrots, crusty bread, nuts... It is advisable to either completely avoid these foods or cut them into smaller, softer pieces. If the appliance becomes loose, please contact us immediately. Thank you for your cooperation.
