Summary

evaluate clinically the postoperative outcomes of the Z plasty frenectomy technique in comparison to modified lip repositioning surgery

Detailed description

Excessive gingival display is a cosmetic problem where it is usually managed by different approaches such as lip repositioning. Aim: Is to evaluate clinically the postoperative outcomes of the Z plasty frenectomy technique in comparison to modified lip repositioning surgery Methodology: The clinical study will include 16 patients with gummy smile divided into two groups equally and randomly according to technique using www.randomizer.org. Group 1: will be treated with conventional modified lip repositioning technique and the labial frenum will be left intact. Group 2: will be treated with z plasty frenectomy. Clinical follow up will be at 1,3, 6 and 9 months. Clinical evaluation will be done through using (VAS). It will be used to measure patient satisfaction through pain killer scale . - Likert scale to measure patient satisfaction - Periodontal probe will be used to measure the relapse. Also signs of infection will be recorded.
