Question: 1 / 400

What is interproximal reduction (IPR)?

The process of removing a small amount of enamel between teeth

Interproximal reduction (IPR) refers specifically to the process of removing a small amount of enamel from between teeth. This technique is often utilized in orthodontics to create additional space for tooth movement, improve the alignment of teeth, and enhance occlusion without the need for extractions. By reducing the width of the teeth at their contact points, IPR allows for better arch coordination and can help achieve desired tooth positioning, making it a valuable tool in treatment planning.

Other options do not correctly describe IPR. The installation of braces on the incisors is a form of orthodontic treatment but does not involve enamel reduction. A space maintainer is a different appliance used to hold the position of a space left by lost primary teeth, while extracting wisdom teeth is unrelated to the orthodontic processes or tooth alignment.
