Rotation of any tooth needs to be corrected in the initial phase of orthodontic mechanotherapy. Derotation of posterior teeth provides space in the arch and also allows the treatment progress. During rotation correction, undesirable forces make an unwanted movement of the adjacent teeth, which increases the duration of treatment. This case report aims to fabricate and introduce the modified Nance palatal arch that easily allows derotation of the tooth without producing undesirable side effect on adjacent teeth.       Keywords: modified Nance palatal arch, derotation, rotated premolar
