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.
