Power chains are a type of elastic orthodontic accessory connected to braces to apply greater force across multiple teeth. This continuous connection, resembling a chain, aids in closing spaces, aligning teeth, and correcting bite issues more effectively than individual elastic ligatures. For example, if a patient has a noticeable gap between their front teeth, a power chain may be used to draw the teeth together and close the space.
The use of these connected elastics is pivotal in certain orthodontic treatments, contributing to faster and more predictable tooth movement. Their implementation represents an advancement in orthodontic techniques, allowing for the management of complex alignment problems that might have previously required more invasive procedures. The capacity to exert consistent and unified pressure across a segment of teeth significantly enhances treatment outcomes.
