Comparison Between Lip Repositioning and Muscle Traction Technique in Treatment of Gummy Smile

The goal of this clinical trial is to compare and evaluate the effectiveness of conventional and modified lip repositioning for the treatment of gummy smile. The main question it aims to answer: Which of these treatment modalities (conventional lip repositioning and containment of the elevator muscle of the upper lip and wing of nose (EMULWN)) has the most durable and least relapse in the treatment of gummy smile?" Researchers will compare: 1. The primary outcome was the decrease in excessive gingival display by measuring smile line (gingival display) and smile index before and after treatment modalities. 2. The The secondary outcome was to measure the durability and possibility of relapse over 6 months after treatment with high patient satisfaction.

For patients seeking long-term correction of excessive gingival displays, there are different treatment modalities. Both lip repositioning and muscle traction techniques showed improvement in the decrease in the amount of gingival display, while the containment surgery of the muscle of the upper lip and wing of the nose showed durable and satisfactory esthetics with less patient discomfort and less pain immediately after the procedure and needs more time to study or may need some modification. Also, lip repositioning showed satisfactory results to the patients but with more pain immediately after the procedure.
