Abstract: |
An oral-seal-forming pressure-applying orthodontic screen seatable within a person's mouth adjacent labial gum structure in the upper and lower arches. A rim portion defines a working screen area, and supports an elastomeric web portion which spans the screen area. The web portion is stretchable to act against protruding teeth with a tooth-position-correcting force when the screen is seated within a mouth.

Claim |
It is claimed and desired to secure by Letters Patent:
1. An oral-seal-forming pressure-applying orthodontic screen comprising:
- a rim portion rigidified with a generally rectangular cross-section defining a working screen area, said rim portion being seatable within a person's mouth adjacent labial gum structure in the upper and lower tooth arches, said rectangular cross-section having an elongated length defining a sufficient contact surface area for resistance against operating forces which tend to move said rim portion out of a position seated in the mouth and;
- an elastomeric web portion connected to said rim portion and at least partially spanning said screen area, and being stretchable against such resistance provided by said rim portion to act against teeth with a tooth-position-correcting force when said rim portion is seated within a person's mouth.
