N preparing this clinic I have constructed six High labial arches, as shown in Figs. 1, 2, 3, 4, 5, 6, 7, and 8. This shows the various types with fkrger springs as I have used them, but, of course, many additional types of finger springs are used by Dr. Lourie.

Stabilize the arch in most cases as is done on the first premolar-s in Figs. 1 ancl 2. If finger springs are securely ligated to teeth or attached to bands of course we have stabilization of the arch.
