NCT06397521 | Not Yet Recruiting DMC

• 1 other identifier: 22879
• Study Type: interventional
• Target: 21
• Locations: 1 country

Brief Summary

In patients with excessive gingival display, esthetic crown lengthening procedure by means of scalpel, diode laser or electro-surgery could result in the same gingival marginal stability at 3 and 6 months follow up.

Conditions

Crown Lengthening

Keywords

Digital; Surgical guide

Outcome Measures

Eligibility Criteria

• Age: 25 Years - 45 Years
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Altered passive eruption as presence of quadratic anterior teeth \[crown width/length ratio
• \].
• Gingival margin located coronal to the tooth cervical convexity and \>2 mm of gingival band display during maximum smile.
• Patients with treated periodontal disease (i.e., stage I of periodontitis);

You may not qualify if:

• Patients with systemic contraindications for oral surgery as uncontrolled diabetes.
• patients on drug therapy related with drug-associated gingival enlargement.
• Areas in which the remaining amount of keratinized gingiva after the submarginal incision is less than 3 mm.
• Previous surgical treatment in the same area.
