Removable oral appliance

Abstract

The removable oral appliance for which registration is sought is formed of a thin-walled body consisting of a U-shaped elongated portion of uniform width and thickness, a U-shaped outer wall extending vertically from the outer end of the elongated portion, and a U-shaped inner wall extending downward from the inner end of the outer wall. The upper part of the outer wall has a wave-like upper edge, and a curved depression is formed in the center front of the upper edge. The inner wall extending downward from the U-shaped elongated portion is slightly inwardly slanted, and its lower edge, as seen in rear view, has a wave-like shape with a depression in the center, and both sides are beveled to the ends of the U-shaped elongated portion. The removable oral appliance for which registration is sought in Variation 4 is characterized by the above common features, in addition to the longer outer portion corresponding to the user's molar teeth, and the thicker U-shaped elongated portion compared to Variation 2. The design for which registration is sought is industrially repeatable using standard equipment and current materials. The removable oral appliances seeking registration are characterized by aesthetic expression, rationality and ergonomics. 4.1) Perspective view; 4.2) Front view; 4.3) Rear view; 4.4) Left side view; 4.5) Right side view; 4.6) Top view; 4.7) Bottom view.
