Introduction

Excessive gingival display, commonly known as a "gummy smile," poses significant aesthetic concerns for individuals, affecting their overall personality. This condition can arise from various factors, including altered passive eruption and tooth mal-positioning. Treatment options for gummy smile range from surgical interventions to orthodontic therapies. In cases involving jaw deformities, orthognathic surgery is often necessary, though it can lead to complications and require hospitalization. An alternative approach is lip repositioning, a minimally invasive surgical procedure aiming to reduce gingival display by limiting the muscle pull of the upper lip during smiling.

Importance of Lip Repositioning Procedure

The lip repositioning procedure focuses on decreasing excessive gingival display by surgically repositioning the upper lip. A case report highlighted its efficacy in treating a 22-year-old female patient who presented with a gummy smile after orthodontic treatment. The surgical technique involved administering local anesthesia, creating incisions to remove a partial thickness flap, and then suturing the incisions to limit the muscle pull of the lip. Post-operative evaluations demonstrated a significant reduction in gingival display from 5-6 mm before surgery to 3 mm at 3 and 6 months post-operation. While patients expressed satisfaction with the results initially, nearly complete relapse of the lip position was observed one year later, suggesting that while the procedure can yield short-term aesthetic improvements, concerns regarding long-term stability remain.

Conclusion

Lip repositioning has emerged as a promising alternative treatment for excessive gingival display, offering an effective means to enhance the aesthetics of patients' smiles with minimal side effects. Despite the initial success shown in a 6-month postoperative period, the long-term efficacy of the procedure is uncertain and warrants further investigation. Future studies with larger sample sizes and extended follow-ups are necessary to better understand the sustainability of results and to establish stronger clinical evidence supporting lip repositioning as a viable solution for gummy smiles.
