The use of clear aligners in patients undergoing orthognathic surgery constitutes an alternative to conventional orthodontic-surgical preparation, presenting certain advantages such as comfort, aesthetics, lower cost and surgical time reduction. The objective of this article is to present, regarding a case, a clear aligner modification applied to surgical orthodontics, which allows intermaxillary fixation (IMF) without resorting to the installation of microimplants. Based on our findings, we can affirm that the modification of the technique presented is capable of providing satisfactory and stable long-term results in a surgical context, presenting numerous advantages with respect to the use of conventional fixed appliances.
