The document discusses different types of buccal canine retractors used in orthodontic treatment including: 1. Standard buccal canine retractor, self-supported buccal canine retractor, buccal canine retractor, and supported buccal canine retractor. 2. It notes that standard buccal canine retractors can be unstable in the vertical dimension making them difficult to adjust. 3. The document provides details on fabricating buccal canine retractors including positioning of the coil, active arm, retentive arm, and tag.

11. They are relatively unstable in the vertical dimension
(see Figure 3.4) which can make them difficult to adjust.

12. Fabrication
Draw the design:
A. Long axis of the tooth.
B. Coil.
A. Coil:
• Located at half of the root length.
• 3 mm diameter.
• 2 mm from sulcus.
B. Active arm:
• Positioned down the long axis of tooth.
• 1 mm away from tooth and tissue surface.

13. C. Retentive arm:
• Going towards of mesial of 2nd premolar.
• Shoulder touch mesial 2nd premolar.
D. Tag:
• Positioned towards the palate.
• Does not sit on tissue (0.5 mm – 1 mm) away.
