Dentofacial deformities are a consequence of discrepancies in the shape and size of the jaws, leading to dental malocclusions and facial disharmony. Orthognathic surgery (OS), through a combined orthodontic-surgical approach, is able to manage such skeletal discrepancies, improving facial aesthetics, occlusion and airway volume. The traditional protocols for treating dentofacial deformities are based on the use of pre- and postsurgical orthodontic treatment. In contrast, surgery-first protocols produce immediate improvement of the facial profile and airway volume, and a noticeable reduction in total treatment duration (On the other hand, fixed orthodontic devices such as brackets complicate oral hygiene, potentially leading to plaque accumulation and periodontal disease (Many articles have evaluated changes in quality of life (QoL) after OS and its functional and psychosocial benefits for patients with dentofacial deformities (The aim of the present study was to comparatively assess periodontal health and QoL among patients with dentofacial deformities combining the surgery-first approach with Invisalign versus fixed appliances. Our hypothesis was that patients in the Invisalign group would have a better periodontal health and higher satisfaction than those in the brackets group.
