Oh, no Don is posting Inman Aligners again!
Yes I am but you might have not seen this one before. It is a Lower IA w/expansion.
Before I go into the details please note the pics where taken without the appliance fully seated. This is why the Adams Clasps look so far off. I would have asked Jesse to take new photos but the appliance shipped. Also the screw should have been placed tighter to the tissue IMO.
Anyway...we used to make the Lower IAs w/expansion using a traditional screw imbedded in acrylic. The problem was this is a weak area of the appliance and they broke from time to time. We started using a 2 arm fixed screw as shown and this solved the problem. The appliance obviously is a bit more bulky using this screw but we never had complaints.
The other appliance is a combination of a printed Hyrax and a Halterman. You all know I love printed metal appliances so I had to post this. Thank you Tim Bertram, your work never disapoints!
If you look at the pics you will see we used both white and black backgrounds. We cannot decide which look better / show the appliance better. I welcome your thoughts.
Have an amazing weekend everyone,
Don
