This study examined the case of 27-year-old female who underwent orthognathic surgery to correct class 3 malocclusion, resulting in an unnatural smile. The research aimed to assess the efficacy of non-invasive treatment in enhancing facial muscle movement during smiling to achieve a natural smile. The patient received eight sessions of treatment using non-invasive devices, and facial assessment were conducted using three-dimensional scanner (Morpheus 3D Scanner) to evaluate facial features in both relaxed and maximum smile states pre- and post-treatment. The results demonstrated improvements in the symmetry of the lower lip height during smiling, along with increases in mouth width and volume in the upper central area. Subjectively, the patient also reported enhanced comfort while smiling. These findings suggest that non-invasive procedures can effectively improve unnatural smiles following orthognathic surgery, contributing to a more aesthetically pleasing smile presentation.

Objective: This study aimed to investigate the effects of structured orofacial muscle rehabilitation training (OMRT) on the recovery of facial expression muscles in patients with skeletal Class II malocclusion after orthognathic surgery.
Study Design: This randomized controlled trial enrolled 56 skeletal Class II malocclusion patients who underwent orthognathic surgery. The intervention group received structured OMRT, while the control group received standard postoperative care.

Limited long-term 3-dimensional (3D) studies exist evaluating risk factors for condylar resorption following orthognathic surgery. Our aim was to evaluate patient demographics, clinical and radiographic characteristics, and orthognathic surgical effects on long-term postoperative condylar volume and height, and horizontal skeletal stability, using a 3D approach. Analysis of clinical data and cone-beam computed tomography before, and approximately two weeks and five years after surgery was carried out on 50 subjects (17 male, 33 female), mean (range) age 25.

Hyperdivergent skeletal Class II malocclusion is largely genetically determined and poses significant challenges in orthodontic treatment, particularly due to compromised facial aesthetics, reduced bite force and airway narrowing. Traditionally, orthognathic surgery has been the standard treatment for correcting such skeletal discrepancies. However, the advent of temporary skeletal anchorage devices (TSADs) has expanded the possibilities for orthodontic camouflage by allowing effective vertical control.

Orthognathic surgery has undergone considerable evolution, marked by increasing prevalence and improved patient experience. Key advancements include shifting aesthetic ideals, the integration of digital technologies for surgical planning, and a growing emphasis on minimally invasive techniques. This study aimed to promote single-maxillary orthognathic surgery by implementing a novel, fully digital workflow protocol to reduce invasiveness.

Background: Inferior alveolar nerve (IAN) injuries are common complications of mandibular orthognathic surgery. Selegiline has demonstrated neuroprotective effects in preclinical studies.
Objective: To evaluate the effect of oral selegiline hydrochloride on neurosensory recovery following bilateral sagittal split osteotomy.
