People Also Ask
What is a low jaw expansion screw used for?
A low jaw expansion screw, or mandibular expander, is used to widen the lower jaw. It corrects a narrow mandibular arch, alleviates dental crowding, and fixes posterior crossbites by applying gentle, controlled force to separate the lower teeth and bone gradually.

How does a mandibular expansion screw work?
The appliance is fixed to the lower molars. Using a special key, the orthodontist periodically turns the central screw. This activation pushes the two halves of the appliance apart, transmitting force to the teeth and supporting bone, thereby encouraging symmetrical expansion of the lower jaw over the treatment period.

Is the lower jaw expander safe for sterilization?
Yes. Constructed from durable medical grade stainless steel, the low jaw expansion screw is fully autoclavable. It can withstand repeated high temperature steam sterilization cycles in an autoclave, ensuring safe reuse and compliance with clinical hygiene protocols.
