What is an Invisalign Power Ridge?

Unlike invisalign power ridges that are visible on the front of your teeth, the clear aligner system uses buttons and elastics that attach to the sides of your teeth and work to push or pull your teeth into place. Your dentist will be able to tell you, before your treatment begins, if your specific malocclusion requires the use of attachments like power ridges.

These auxiliary features are designed to increase the force of an aligner against the tooth when performing certain types of movements, such as lingual root torque. They can also be used to reduce the frequency of required visits by limiting how fast your teeth move during treatment, so you’ll need to replace your aligner less often.

Beyond Straightening: Exploring the Enhanced Benefits of Invisalign Power Ridge Aligners

Invisalign’s power ridge is a series of small bumps on the side of your incisors that are designed to help the aligner grip the surface of the tooth and generate an inward or outward force on the tooth. The power ridge can be found on both the upper and lower incisors and helps to perform a variety of orthodontic movements, including translation, tipping, and torquing.

The power ridge is usually made of plastic and is placed on the lingual side of the upper or lower incisors. There is a debate among Invisalign educators about whether the bevel on the power ridge should be oriented towards the incisal edge or the gingival edge of the tooth. Some believe that the bevel should be oriented towards the incisal Edge because it would create a large “ledge” that could provide maximum grip for the aligner and lead to greater predictability of absolute extrusion.
