Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

study group: z plasty frenectomy

Participants in the study group will be treated with Z- plasty frenectomy and will be followed up for 9 months

Group Type EXPERIMENTAL

z plasty frenectomy

Intervention Type PROCEDURE

Z-plasty frenectomy is a surgical procedure in which the frenum is released and rearranged using a Z-shaped incision. This technique helps improve tissue mobility and reduce tension. The procedure is performed under local anesthesia"

control group : modified lip repositioning

Participants in the control group will undergo modified lip repositioning with a follow-up period of 9 months.

Group Type EXPERIMENTAL

Modified lip repositioning

Intervention Type PROCEDURE

"Modified lip repositioning is a minimally invasive surgical technique used to reduce excessive gingival display. The procedure involves removing a small strip of mucosa and repositioning the upper lip to limit its upward movement during smiling. It is performed under local anesthesia ."
