People Also Ask
What is an expansion screw used for?
An expansion screw is primarily used to widen the upper jaw in orthodontic treatment. It addresses issues such as dental crowding, crossbite, and narrow arches by applying gentle, controlled force to the palate. This process creates additional space for teeth alignment and improves overall oral function and facial symmetry.

How does a Hyrax expansion screw work?
The Hyrax expansion screw works by turning a key inserted into its central mechanism. Each turn activates the screw to separate the two halves of the appliance, which are bonded to the upper molars. This gradual separation encourages the mid-palatal suture to widen, leading to skeletal expansion over time. The treatment is typically monitored by orthodontic professionals to ensure safe and effective results.

Is the expansion screw reusable?
Yes, the expansion screw is made from durable stainless steel and can be sterilized using high-temperature autoclaving. This makes it suitable for multiple uses in dental clinics and hospitals, provided it is inspected for integrity and functionality before each application.
