How does the Twin Block appliance help my child?
The Twin Block appliance is made of two removable plates that attach to the upper and lower teeth. It holds your child’s jaws apart while moving the lower jaw forward.
This positioning helps maximise the growth potential of your child’s lower jaw while correcting problems like size difference and protrusion.
Occasionally, the upper plate can have an expansion feature that allows a narrow dental arch to widen. This can correct a crossbite, create more room to fix crowded teeth and align the upper and lower jaws better.
Parents of patients usually conduct the expansion process at home using a small screwdriver called a ‘key,’ which helps loosen the screw and open the plate as necessary.
