Since the invention of the ruby laser in the early 1960s, tremendous advances have been made in optic laser technology. Orthodontists have found various uses for lasers, including the debonding of ceramic brackets. Laser energy degrades the adhesive resin used to bond brackets. Consequently, lower forces can be used than when mechanical debonding is performed, reducing the risk of enamel damage. However, the heat produced by some lasers can damage the tooth pulp. Selecting the appropriate laser, resin, and bracket combination can minimize risks and make debonding more efficient. The purpose of this article is to give the clinician an up-to-date, comprehensive literature review about the clinical characteristics of debonding ceramic brackets with lasers.
自20世纪60年代初红宝石激光发明以来，光学激光技术取得了巨大进展。正畸医生发现了激光的各种用途，包括陶瓷托槽的脱粘。激光能量会降解用于粘结托槽的粘结树脂。因此，与机械脱粘相比，可以使用更低的力，从而降低牙釉质损伤的风险。然而，一些激光产生的热量会损伤牙髓。选择合适的激光、树脂和托槽组合可以将风险降至最低，并使脱粘更有效。本文的目的是为临床医生提供一篇关于使用激光脱粘陶瓷托槽临床特征的最新、全面的文献综述。
