Abstract
Backgrond: Until now, there have been many studies on the postoperative stability of orthognathic patients treated with traditional fixed orthodontic appliances. Recently, the use of clear aligners as orthodontic appliances has increased in orthodontic treatment for aesthetic and patient convenience. The aim of this preliminary study was to investigate the stability and characteristics of patients undergoing orthognathic surgery using clear aligners. Patients and Methods: This study was performed on patients who underwent orthognathic surgery by one surgeon at Pusan National University Dental Hospital from April 2017 to August 2021. A comparative study was conducted on five patients treated with clear aligners during orthodontic treatment and ten patients treated with traditional fixed appliances as a control group. Postoperative skeletal changes and recurrence were evaluated by cone beam computed tomography and lateral cephalometric radiographs taken two days postoperatively and six months postoperatively. Several measurement variables were used to confirm the presence or absence of recurrence, preoperative and postoperative orthodontic treatment period, and the number of extracted teeth. Results: Postoperative stability for six months after surgery was not significantly different between the clear aligner group and the traditional fixed appliance group. The preoperative orthodontic treatment period was also shorter in the clear aligner group, and the number of extracted premolar teeth and impacted teeth were also fewer in the clear aligner group, but there was no significant difference. Conclusions: Orthodontic treatment using clear aligners continues to develop, and it is believed that there is no limit to what can be accomplished during orthodontic surgery accompanied by clear aligners.
Highlights
The number of extractions of premolars and the number of impacted teeth was smaller in the group treated with clear aligners, but there was no significant difference between the two groups (Table 2)
Even when using preoperative orthodontic treatment with clear aligners, there was no difficulty in combining clear aligners with orthognathic surgery cases
It is thought that similar results can be obtained using the combination of clear aligners with orthognathic surgery as compared with conventional surgery
Summary
Since Kesling first invented the aligner in 1946, an aligner for tooth alignment has been developed [1]. Patient demand has increased for more orthodontic treatments with esthetic appliances [2]. Launched the Invisalign system in 1999, which enables esthetic orthodontic treatment because traditional braces are not invisible. This was the first CAD (computer-aided design) and CAM (computer-aided manufacturing)-based orthodontic appliance, which can be digitally scanned, and made as a series of aligners using a single impression [3,4]
