Aim: The present study was performed to evaluate the longevity and efficacy of the lip repositioning surgery by assessment of the gingival display changes that occur after the surgery through clinical & digital methods.

Methods: This prospective study included ten female patients who suffered from excessive gingival display due to upper lip hypermobility or short upper lip. Pre-operative measurement of the amount of gingival display were recorded both clinically using an endodontic ruler & digitally using Adobe Photoshop cs6 through a well standardized photographs. The surgery was performed under local anesthesia for all patients by removing part of the labial mucosa (labial vestibule) followed by suturing of the wound by interrupted 0-5 resorbable suture. All patients were followed up at 14 days, 4 months, 8 months and 12 months, postoperative assessment was done by measuring the changes in the gingival display using the same clinical & digital techniques.

Results: Post-operative measurements at 14 days follow up, showed obvious reduction in the amount of gum exposure. However complete relapse was observed at 4 months.

Conclusion: The longevity of the procedure is questionable with almost complete relapse.
