People Also Ask: What is the function of an expansion screw in orthodontics?
An expansion screw, also known as a hyrax screw or midline expander, is a mechanical device embedded in an orthodontic appliance. Its primary function is to generate gentle, controlled force to widen the dental arch or the palate. By regularly turning the screw with a special key, the appliance separates, promoting bone growth and moving teeth into a more ideal position. This process is crucial for correcting underdeveloped arches, creating space for crowded teeth, and improving overall bite alignment.

Complete Usage & Applications

This standard expansion screw is a versatile core component for dental technicians and orthodontists. Its primary use is in the fabrication of custom fixed or removable expansion appliances prescribed for patients. Key applications include constructing midline expansion devices to correct bilateral crossbites and palatal constriction, creating space maintainers for pediatric dentistry, and building habit-breaking appliances. It is integral for treating maxillary deficiency, facilitating arch development to relieve crowding without extractions, and preparing the arch for subsequent orthodontic treatment. The screw’s activation mechanism provides predictable, bilateral force, making it a trusted choice for non-surgical rapid or slow maxillary expansion protocols in growing patients and even adults in certain cases. Its durable, biocompatible stainless-steel build ensures consistent performance throughout the treatment period. Sourced from precision manufacturers in Hangzhou, China, a hub for quality dental supplies, this component meets the stringent demands of European and Russian B2B clients, including wholesale distributors, dental laboratories, and clinical practices seeking reliable, cost-effective orthodontic inventory.
