About Bending the Archwire In this book, we attempt to explain the design and mechanical characteristics of the standard edgewise orthodontic appliance in contradistinction to those of the preadjusted edgewise appliance. The principles and techniques of the standard edgewise orthodontic treatment described are based on the Tweed edgewise orthodontic technique which has been employed and modified in the Department of Orthodontics and Dentofacial Orthopaedics at Osaka University. Mastery of the standard edgewise technique benefits orthodontic experts because in doing so they become able to refine treatment outcomes, optimizing care for each individual patient at a level which cannot be attained by simply using a preadjusted edgewise appliance. The standard edgewise technique allows the practitioner to produce a made-to-order occlusion that is aesthetically and functionally optimal.

矯正歯科治療の成否は、歯科医師の治療技術の巧緻性、すなわち手先の器用さと美的感覚に大きく依拠している。本書では、歯の移動を直接行う矯正力を発揮するアーチワイヤーの屈曲のコツと、それがいかにプレアジャストエッジワイズ矯正歯科治療法において役立つかに焦点をおき、具体的な画像を示しつつ、詳細に技術的ポイントを解説する。歯科矯正学を専攻する大学院生や矯正歯科医のための類をみない技術指導書である。
