Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Marking the bleeding points
* An internal bevel incision is made followed afterwards by a sulcular incision.
* The gingival collar is eliminated.
* Elevation of the flap is proceeded to allow access for osteoplasty using piezo surgery and an apical position of the bone 2-3mm beyond CEJ.
* Mattress suture (6.0) is made
The intervention approach:
Surgery is done the same as in the conventional approach but without opening a flap, gaining access via a tunneling instrument and piezo tips for osteoplasty

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
The conventional approach
Conventionnal ECL using piezosurgery and microsurgical tools
Micro-surgical crown lengthening approach using Piezosurgery
excess gingiva is eliminated. 2 mm bone is removed from CEJ-bone crest with piezo surgery with conventional flap elevation.
The intervention approach:
