INTRODUCTION

Transpalatal Arch (TPA) has been invented by Dr. Robert Ara Goshgarian, a renowned orthodontist more than 7 decades ago. Throughout the years, various modifications of the design were made for different purposes and to increase its efficacy in achieving the optimum level of anchorage. In 1947, fabrication of Nance Palatal Ach (NPA) pioneered the adjustment of TPA by incorporation of an acrylic button that connects the palatal wire at the highest part of palatal vault. Recent innovations mostly involved adhesions of TPA to mini implants or temporary anchorage devices (TAD) and ...
