About

This retrospective study aims to evaluate the effectiveness and safety of a modified lip repositioning surgery technique, performed without frenectomy and without myotomy, for the correction of excessive gingival display ("gummy smile"). Data were collected from the medical records and clinical photographs of patients who had previously undergone this surgical procedure at the study site.

Full description

Excessive gingival display, commonly referred to as a "gummy smile," is an esthetic concern that may reduce patient satisfaction with their smile and overall facial appearance. Several treatment modalities have been suggested to address this condition, including orthodontic treatment, botulinum toxin injection, and various surgical techniques. Among surgical approaches, lip repositioning surgery has gained popularity due to its minimally invasive nature and ability to provide predictable esthetic outcomes.

A modified lip repositioning technique, performed without frenectomy and without myotomy, has been introduced to reduce morbidity and simplify the procedure while maintaining effectiveness. However, published evidence has largely come from prospective interventional series.

To further evaluate the clinical performance of this modified technique, we conducted a retrospective observational cohort study. Data were obtained from the medical records and clinical photographs of patients who had previously undergone the modified lip repositioning surgery at the study site. No new patients were enrolled and no interventions were prospectively carried out.
