Laser-Assisted Minimally Invasive Esthetic Crown Lengthening Using Flapless vs. Tunneled Flap Approach

Enrolling by invitation · Not applicable

Conditions studied: Altered Passive Eruption of Teeth

In brief

Crown lengthening surgery is one of the most commonly performed periodontal procedures. Multiple techniques have been used throughout the years to overcome the postoperative pain and adverse outcomes that may be associated with surgical crown lengthening. One of the most popular choices among clinicians is using different types of lasers in different techniques to overcome those adverse effects. Treatment effectiveness can be monitored non-invasively through salivary levels of Leukocyte Esterase enzyme and the stability clinical outcomes.
