Abstract：
Pre- and postoperative fixed orthodontic appliances are the customary and standard practice for patients with treatment planned for undergoing orthognathic surgery. Traditionally, most patients undergoing orthognathic surgeries are in their late teens. Although these patients still compose the greatest pool of the orthognathic surgery population, many patients seek orthognathic surgery later in life. This older patient population often has different concerns and goals than the younger patient population. One of these concerns is often the aesthetic appearance of fixed appliances and the time required to wear these appliances pre- and postoperatively. Today, removable orthodontic appliances consisting of a series of clear aligners have gained immense popularity due to their aesthetic appeal over traditional braces. Additional benefits of removable orthodontic appliances include improved oral hygiene leading to a decreased risk of gingivitis. Whereas clear aligner systems are commonly used in the nonsurgical orthodontic population, there has been limited use of Invisalign in the orthognathic surgery population. In this article, we present a case series of 5 patients who successfully underwent orthognathic surgery using clear aligners for pre- and postoperative orthodontic treatment.
摘要：
术前和术后固定正畸矫治器是计划接受正颌手术治疗的患者的习惯和标准做法。传统上,大多数接受正颌手术的患者都在十几岁左右。尽管这些患者仍然构成了最大的正颌手术人群，许多患者在以后的生活中寻求正颌手术。这种年龄较大的患者群体通常具有与年轻患者群体不同的关注点和目标。这些问题中的一个通常是固定器具的美学外观以及手术前和手术后佩戴这些器具所需的时间。今天,由一系列清晰的矫正器组成的可移动正畸矫正器由于其相对于传统牙套的美学吸引力而获得了极大的普及。可移除正畸矫治器的额外益处包括导致牙龈炎风险降低的改善的口腔卫生。尽管清晰的矫正器系统通常用于非手术正畸人群，在正颌手术人群中，Invisalign的使用有限。在这篇文章中,我们介绍了一个病例系列，包括5例成功接受正颌手术的患者，这些患者使用清晰的矫正器进行术前和术后正畸治疗。
