Powerchain is a set of linked elastic bands that are used in a variety of ways to move teeth orthodontically.
There are generally 2 types of powerchain: open and closed.
- Open chain: has a length of elastic separating the links
- Closed chain: has continuous links.
Powerchain can be used to slide teeth along archwire to close spaces, to engage auxiliaries like power arms, temporary anchorage devices (TADs) or buttons; and even to tie in appliances like the arms of a mandibular advancement repositioning appliance (MARA).
Powerchain is very versatile and is a useful addition to the orthodontic toolbox. The method in which it is used will depend on the case and the dentist. Remember that it is the operator that makes a difference in how something is used.
