What is Interproximal Reduction (IPR)?

IPRIPR is the abbreviation for Interproximal Reduction. Despite the fact that this process is employed with all varieties of orthodontic repair, it is a common part of Invisalign treatment to restore crowded teeth. As a result, our Sacramento dentists want you to understand the answers to these questions: what is IPR and why is it a common orthodontic process for treating specific difficulties with the smile and our teeth?

Interproximal Reduction Explained

IPR is also named “enamel reduction,” because it focuses on abrading away little layers of the outermost tooth enamel from multiple teeth in areas that are crowded or that surround crowded teeth. Flexible strips of very fine material, like sandpaper, are employed to rub away very minute layers of the outermost tooth enamel. Hand tools or dental instruments are employed to accomplish IPR. A standard tooth loses no more than .2 or .3 millimeters of outer tooth enamel during the complete Invisalign treatment experience. Healthy enamel can be 2.5 millimeters thick, so IPR removes merely a tiny quantity and is only done on specific teeth — not all of them.

IPR is used alongside other orthodontic techniques, especially adjustments to the arch width and the proclination, or incline, of the teeth. Commonly, folks with crowded teeth have small arches and their teeth are leaning in a way that increases their difficulties. By enlarging the arch and fixing the proclination, considerably more room is automatically created for all the teeth. The little amounts of IPR done on specific teeth during your orthodontic therapy allows them to move into their appropriate locations along the mandibular and maxillary arches.

IPR Alternatives

The main alternative to IPR is extracting one or more of the crowded teeth to create room for those that are left behind. Most patients, if given the choice between pulling teeth and enamel reduction, commonly decide to go with IPR! This truthfully makes sense if you realize that the extraction process usually requires the dentist to remodel one or more of the remaining teeth by using IPR!

The Sacramento Dentistry Group thinks every tooth is necessary and should be saved if at all possible. IPR helps meet this goal when dealing with crowded teeth. It encourages more stability of the teeth, requires no healing period (unlike extractions), and speeds up your orthodontic therapy, saving the patient time and costs.
