The Use of Clear Aligner Therapy for Orthognathic Surgery Patients: A Cross-Sectional Survey Among Saudi Orthodontists and Oral and Maxillofacial Surgeons

<ns7:p> Background Orthognathic surgery corrects severe skeletal discrepancies that cannot be addressed by orthodontics alone. With advancements in digital workflows and CAD/CAM technologies, clear aligner therapy (CAT) has emerged as a potential adjunct in surgical cases. However, its clinical application remains under-researched. This study aimed to assess the knowledge, experience, and attitudes of orthodontists and oral and maxillofacial surgeons in Saudi Arabia regarding CAT in orthognathic surgery patients. Methods A cross-sectional survey was conducted from April 1 to May 31, 2023, using a closed-ended online questionnaire distributed to specialists across Saudi Arabia. The survey gathered demographic and clinical data. Statistical analysis included descriptive methods, chi-square testing (p &lt; 0.05), and univariate regression to identify demographic predictors of CAT use. Results Out of 278 expected responses, 46 (16.5%) were received. Most participants were aged 31–40 years (p &lt; 0.05) and had 6–10 years of experience (p = 0.03). Orthodontists accounted for 65.2% of the respondents, with oral and maxillofacial surgeons at 34.8% (p = 0.03). While most treated 1–4 orthognathic patients monthly, 80% had no experience using CAT in these cases. Although general CAT usage was significant (p &lt; 0.05), its clinical application in orthognathic surgery was minimal. Challenges included pre-surgical alignment, intraoperative fixation, and post-operative occlusion control. Regression analysis showed that age was significantly associated with CAT use (p &lt; 0.05; R <ns7:sup>2</ns7:sup> = 0.38), while gender and experience were not. Conclusion The study indicates limited clinical experience with CAT in orthognathic surgery in Saudi Arabia. Age may influence CAT adoption, but further studies with larger sample sizes are needed to validate these findings and inform future integration of aligner protocols in surgical orthodontics. </ns7:p>
