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

| z plasty frenectomy | 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" |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Gingival Display (mm) | Gingival display will be assessed in millimeters using standardized clinical photographs taken at maximum smile. Measurements will be performed using a periodontal probe to determine the vertical distance between the inferior border of the upper lip and the gingival margin of the maxillary central incisors. A reduction in gingival display indicates improvement, while an increase indicates relapse. Measurements will be recorded at baseline and during follow-up visits. | Up to 9 months |
| Measure | Description | Time Frame |
|---|---|---|
| Pain score | Postoperative pain will be assessed using a Visual Analog Scale (VAS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Lower scores indicate less pain. | Up to 9 months |
| Patient Satisfaction Score |

| Modified lip repositioning | 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 ." |

|
Patient satisfaction will be evaluated using a numerical rating scale from 0 to 10, where 0 indicates complete dissatisfaction and 10 indicates maximum satisfaction. Higher scores indicate greater satisfaction.
| Up to 9 months |
| Signs of infection | Postoperative infection will be assessed clinically based on the presence of signs such as redness, swelling, pain, discharge, or delayed healing at the surgical site. The outcome will be recorded as present or absent. | Up to 9 months |
| Surgical Time | Surgical time will be measured in minutes from the initial incision to the completion of wound closure. Shorter surgical time indicates a more efficient procedure. | During surgery |
