When performing crown lengthening surgery, especially in the esthetic zone, the positional stability of gingival tissues is considered a prime important goal. The rebound of gingival margins after surgery can result in compromising the esthetic outcome and patient satisfaction. It was proven throughout the literature that there are many factors that may influence the stability of gingival margin position after surgery such as: the surgical technique being performed, experience of the clinician, periodontal phenotype and distance of flap with respect to the alveolar crest.
