I want the same appliances for the lower and upper jaw, however I have extracted both upper and lower teeth. One on the upper and two on the lower is that a problem??

The appliance moves the lower jaw forward and should still work with 3 missing teeth. Thanks

Is there any retraction of the maxilla with this? Can this be done along with expansion?

How much of an overjet can be corrected successfully with this?
