Assessing the Pros and Cons of Performing Orthognathic Surgery in Patients Undergoing Orthodontic Aligner Treatment

Abstract

Objective: Orthodontic aligners have become one of the most requested treatments by patients. This study evaluated maxillofacial surgeons´ experience of using orthodontic aligners in preparation for orthognathic surgery. Methods: A survey using an online platform was used to identify some key points about maxillofacial surgeons´ prior experiences with orthodontic aligners in the context of orthognathic surgery. Participants were asked to discuss their experience with orthognathic surgery preparation through orthodontic aligners. Results: In total, 396 surveys were sent, the sample consisted of 92 respondents. The experience of maxillofacial surgeons on this topic is not very large, some of them (45.65%) have not had contact with orthodontic aligners. Advantages include patient convenience and easy postoperative hygiene, while some disadvantages include inefficient postoperative occlusal stability and intermaxillary block and some difficulties in using elastic bands. A very helpful explanation to solve some problems was highlighted by the surgeons, including a more detailed conference on orthodontic preparation. Maxillary segmentation must be avoided according to the majority of surgeons. Conclusion: The results of the study indicate that not all cases are suitable for orthognathic surgery prepared with orthodontic aligners. While orthodontic aligners offer advantages such as patient-friendliness and improved hygiene, the lower number of surgeons reporting these benefits compared to the disadvantages underscores challenges related to postoperative occlusal stability and limitations with intermaxillary blocks and elastic band usage.
