How do our teeth move when power chains are attached?

Doctor's Answers 1

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.

Is it possible to keep all my teeth aligned but create a front gap between my two front teeth to correct a slight underbite?

Hi there, It really depends on the extent of the underbite and the current position of the two front teeth. Mild underbites can be corrected by: 1) moving the lower teeth backwards (space is required) 2) moving the upper front teeth forwards (which creates spaces/gaps), OR 3) a combination of both. Yes, it is possible to keep all your teeth aligned and for the upper front teeth to be pushed forward to be positioned over the lower front teeth.
