Question

Which of the following is used to tie the arch wire into orthodontic brackets?

1) Separating wire
2) Wire ligatures
3) Elastomeric ligatures
4) Both B and C

Answer 1

Both wire ligatures and elastomeric ligatures are used to tie the arch wire into orthodontic brackets, which are critical components in the application of corrective forces for teeth alignment. Option 4.

Step-by-step explanation:

The materials used to tie the arch wire into orthodontic brackets are called ligatures. There are two types of ligatures: wire ligatures and elastomeric ligatures. Wire ligatures are small pieces of wire that wrap around the bracket to hold the arch wire in place. Elastomeric ligatures are small elastic bands that fit over the brackets, achieving the same purpose. Thus, the correct answer is 4) Both B and C, as both wire ligatures and elastomeric ligatures are used in orthodontic treatment to apply force to teeth and help in their realignment.

The orthodontic brackets are tied to the arch wire using wire ligatures and elastomeric ligatures, which are both options B and C. Wire ligatures are thin wires that are twisted around the brackets to secure the arch wire in place. Elastomeric ligatures are small rubber bands that are stretched over the brackets and the arch wire.
