In 1967, Young H. Kim created the multiloop edgewise archwire (MEAW) to treat open bite malocclusions, which he achieved with great efficiency. Subsequently, Prof. Young-il Chang (Seoul National University, Seoul, Korea) studied the MEAW mechanics to establish the principles. Young H. Kim applied it to all types of malocclusions. MEAW can be constructed with stainless steel 0.016 × 0.022 (bracket 0.018 inch slot) or 018 x 0.022 or 0.017 × 0.025 ss (bracket 0.022 inch slot). The MEAW requires wire bending, which seems very old-fashioned, but it is still very useful in many cases. This lecture will present both old and contemporary cases allowing the audience to easily understand the MEAW techniques.
