This th t Wire c p ra e very efficiently in form- In Figures 4, 5 and 6 the modified buccal tube is of a construction similar to that of Figures 1 to 3. There is provided, however, a lateral extending portion I2 which extends from the arched portion 2. In forming the arched portion 2, this extension 12 is also arched and in the final construction of the tube the portion 12 becomes a continuation of the arched portion, all as clearly shown in the figures. The purpose of this extension it is to provide an anchor means for the tie wire H, which wire is looped about the extension after it has been passed through the depression 9 in the outer surface of the underlying portion 6 of the tube. Thus with the extension l2 there is provided an integral part on the tube to which the tie wire can be anchored and thereby firmly hold the arch wire Iil in the passage 1 of the tube and prevent any relative movement between the tube and the arch wire.

Being aware of the possibility of modifications in the structures shown and described, I do not intend that the invention embodied therein be in any way limited except in accordance with the appended claims.

What'is claimed is:

1. An orthodontic bracket formed of a single sheet of material and comprising upper and lower contiguous positions, said upper portion being bent to form an arch wire receiving tubular socket extending between two opposite edges thereof, and the lower portion having its outer surface depressed so as to provide a tie wire receiving passage when said lower portion is attached to a supporting surface with respect to which an arch wire is to be secured.

2. An orthodontic bracket formed of a single sheet of material and comprising upper and lower contiguous positions, said upper portion being bent to form an arch wire receiving tubular socket extending between two opposite edges thereof, and the lower portion having its outer surface depressed so as to provide a tie wire receiving passage coextensive with said tubular socket when said lower portion is attached to a supporting surface with respect to which an arch wire is to be secured.

3. An orthodontic bracket of the character described in claim 1 wherein the part of the upper portion which defines the tubular socket extends beyond one edge of the lower portion.
