Corresponding Author: Sridhar Kannan, Professor, Department of Orthodontics, Sudha Rustagi Dental College and Research Center Faridabad, Haryana, India, e-mail: sridharkannan_in@yahoo.com Low-placed transpalatal arch (TPA) usually indicated in cases requiring molar intrusion often lead to indentations of the U loop on the dorsum of tongue, thus causing discomfort and irritation to the patient.1 A simple modification using archwire sleeve over the loop of the TPA can eliminate these problems.2 It can be fabricated by using the following techniques: 1. An archwire sleeve of 1 inch length with 0.31" (internal diameter) was passed over the 0.9 mm wire before fabrication of TPA loop (Fig. 1).
