摘　　要：直丝弓矫治减少了弓丝弯制,强调托槽粘接的精准性,而托槽间接粘接技术较直接粘接具有定位精准、椅旁操作时间短的优点,因此间接粘接技术在直丝弓矫治领域受到青睐。然而传统间接粘接方法实验室操作过于繁琐。近几年数字化技术的应用和发展促使直丝弓托槽间接粘接趋向于精准化和个性化,并极大地简化了操作步骤,带来了质的改变。本文将就数字化三维牙颌模型的重建、3D打印等技术在唇侧直丝弓托槽间接粘接领域的应用与研究进展作一综述。Indirect bonding of brackets is characterised by more accurate positioning and shorter chair time compared with direct bonding.The straight wire technique reduces the archwire bending and emphasises the accuracy of bonding positions of brackets.Thus,indirect bonding is favoured in straight wire technique.However,the laboratory operation of the conventional indirect bonding method is very complex.In recent years,with the advance digital technology,indirect bonding of straight wire brackets has become more accurate,personalised and simplified.This,some remarkable changes have been obtained.This article reviews the application and development of digital technology,such as three-dimensional(3D)dental cast reconstruction and 3D printing,in the indirect bonding of labial straight wire brackets.
