Combined treatment approach: A review of using clear aligners in orthognathic surgery procedures.

Abstract

Background: Clear aligner therapy (CAT) was originally introduced for minor orthodontic corrections. However, with technological advances and increasing patient demands for esthetic and comfortable treatments, its application has expanded into more complex cases, including orthognathic surgery. This narrative review explores the use of clear aligners across all phases of orthognathic treatment, such as presurgical, surgical, and postsurgical.

Materials and methods: The literature from 2000 to 2025 was analyzed, identifying 34 relevant studies.

Results: Findings indicate that CAT can effectively manage dentofacial deformities such as skeletal Class II and III malocclusions, open bites, and craniofacial anomalies when used pre- and/or postoperatively.

Conclusion: Clear aligners offer significant advantages in esthetics, oral hygiene, treatment comfort, and quality of life. The combination of surgery and CAT has been demonstrated to reduce treatment time and increase patient satisfaction without compromising skeletal stability. Although there are some limitations, such as concerns about relapse and aligner rigidity in early postoperative phases, the results of occlusal stability, periodontal health, and patient satisfaction are promising. The increasing use of CAT in orthognathic surgery cases, particularly in digitally driven interdisciplinary treatment plans, is supported by this review as an effective and patient-centered alternative to fixed appliances.
