Non-invasive procedure implementation for enhanced smile facial muscle movement after orthognathic surgery: a case report

This study examined the case of 27-year-old female who underwent orthognathic surgery to correct class 3malocclusion, resulting in an unnatural smile. The research aimed to assess the efficacy of non-invasive treatment inenhancing facial muscle movement during smiling to achieve a natural smile. The patient received eight sessions of treatmentusing 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 demonstratedimprovements in the symmetry of the lower lip height during smiling, along with increases in mouth width and volume inthe upper central area. Subjectively, the patient also reported enhanced comfort while smiling. These findings suggest thatnon-invasive procedures can effectively improve unnatural smiles following orthognathic surgery, contributing to a moreaesthetically pleasing smile presentation.
