In the early days of fixed-appliance orthodontic treatment, brackets were welded to gold or stainless steel bands. Before treatment, the orthodontist had to create enough space around each tooth to accommodate the bands, and then those spaces had to be closed at the end of treatment, when the bands were removed. This was time-consuming for the orthodontist and uncomfortable for the patient. Banded appliances frequently caused gingival trauma when fitted, and decalcification could occur under the band. In the mid-1960s, Dr George Newman, an orthodontist in Orange, New Jersey, and Professor Fujio Miura, chair of the Department of Orthodontics at Tokyo Medical and Dental University in Japan, pioneered the bonding of orthodontic brackets to enamel. Many developments have occurred in the decades that followed, including many new adhesives, sophisticated base designs, new bracket materials, faster or more efficient curing methods, self-etching primers, fluoride-releasing agents, and sealants. The purpose of this article is to review the history of orthodontic bonding, especially the materials used in the bonding process.
在固定矫治器正畸治疗的早期，托槽被焊接在金或不锈钢带环上。治疗前，正畸医生必须在每颗牙齿周围创造足够的空间来容纳带环，而在治疗结束取下带环时，这些空间又必须关闭。这对正畸医生来说很耗时，对患者来说也不舒服。带环矫治器在安装时经常会导致牙龈创伤，并且带环下方可能会出现脱矿现象。20世纪60年代中期，新泽西州奥兰治的正畸医生乔治·纽曼博士和日本东京医科齿科大学正畸系主任三浦富士夫教授率先将正畸托槽粘结到牙釉质上。在随后的几十年里出现了许多进展，包括许多新型粘合剂、精密的基底设计、新型托槽材料、更快或更高效的固化方法、自酸蚀底漆、氟释放剂和封闭剂。本文的目的是回顾正畸粘结的历史，尤其是粘结过程中使用的材料。
