Comparing Two Techniques to Treat Gummy Smile Patients: Flapless Piezo-surgery Versus Conventional Open Flap Surgery.

The goal of this clinical trial is to compare and evaluate the effectiveness of conventional surgery and Piezo-surgery for the treatment of gummy smile. The main question it aims to answer: "Which of these treatment modalities (conventional open flap crown lengthening with rotary handpiece and Flapless crown lengthening with Piezoelectric ultrasound has the best clinical results with least morbidity and least relapse in treatment of gummy smile?" Researchers will compare: The primary outcome was the decrease in excessive gingival display by measuring the length of clinical crown and width of keratinized gingiva before and after treatment modalities. The The secondary outcome was to measure the durability and possibility of relapse over 6 months after treatment with high patient satisfaction

Periodontal Tissue Stability After Surgical Correction of Altered Passive Eruption

This prospective, single-group interventional study will evaluate the stability of periodontal tissues after esthetic periodontal surgery for the correction of altered passive eruption in individuals with excessive gingival display. Ten adult participants with excessive gingival display associated with altered passive eruption and involvement of the alveolar bone will be included. Participants will undergo esthetic crown-lengthening surgery consisting of gingivectomy and osseous recontouring. Periodontal clinical measurements, intraoral digital scans, cone-beam computed tomography, standardized photographs, and patient-reported outcomes will be obtained before surgery and during follow-up. Clinical and three-dimensional tissue changes, esthetic perception, satisfaction, and oral health-related quality of life will be evaluated for up to 12 months after treatment.
