  • The effectiveness of the appliance depends upon ofr which it is being used and when that is at what age it is being used. Normally the Haas appliance is used in adolescent age when the sutures are not fused but the derichweiler appliance is used in aults to open the fused mid palatine sutre along with the surgery as a post operative appliance.For more info on palatal expansion you can visit the following link......www.identalhub.com/article_palate-expansion-screw-242.aspx
