U-Loop Canine Retractor Fabrication Stepwise within 8 minutes  

U" loop canine retractor when minimal canine retraction (1-2mm) is required, a relatively simple and less bulky retractor can be used, such as a U-loop retractor. However, it is mechanically less effective than the other retractors. It is made up of 0.6or0.7mm SS wire and consists of an active arm, U-loop and a retentive arm. The base of the U'-loop is placed 2-3mm below the cervical margin, the active arm is bent at right angles from the mesial leg of the loop and adapted around the canine.The distal leg of the loop extends as the retentive arm. This retractor is activated by compressing the loop or by cutting the free end of the active arm by 2mm and readapting it.
Wire used: 0.6 or 0.7 mm hard stainless steel wire is used for the fabrication of this type of canine retractors. Parts of “U” loop canine retractor .
1. Active arm
2. “U” loop
3. Retentive arm
4. Retentive tag.
a. Active arm: It includes: Active arm is bent at right angles from the mesial leg of the loop. Active arm is adapted around the canines.
b. U-loop: It includes: The base of the “U” loop is placed 2-3 mm below the cervical margin.
U” loop consists of the two legs: 1. Mesial leg 2. Distal leg Retentive arm: T he distal leg of the loop extends as the retentive arms. Activation of “U” Loop Canine Retractor T his retractor is activated by compressing the loop or by cutting the free end of the active arm by 2 mm and readapting it. Indication T his type of canine retractor is indicated when the minimal canine retraction of 1 to 2 mm is required.
