Root Resorption Following Treatment with Aligners

Abstract

Can orthodontically induced inflammatory root resorption (OIIRR) be the result of Invisalign treatment? Since OIIRR was first described in the literature, orthodontists have been looking for a treatment procedure where no root shortening will occur. In the past decade, Invisalign orthodontic treatment has become very popular, and there is no description of OIIRR after this treatment. Therefore, it might be incorrectly concluded that the body is immune to this type of orthodontic treatment modality and no OIIRR appears as a result of this treatment. The following case report demonstrates an aspect of the complexity of OIIRR.
