What is Hyrax Expander Screw Position Effects about?

1) A finite element analysis study evaluated the stress distribution in the maxilla under different positions of the expansion screw in a hyrax expander. 2) Six models were created with variations in the vertical (15mm and 20mm from occlusal plane) and anteroposterior positions of the screw. 3) The results showed that an more occlusal and anterior screw position was more efficient at transferring mechanical forces, concentrating stress around the incisive foramen and distributing it through the midpalata
