Surgical Crown Lengthening: A 12‐Month Clinical Wound Healing Study

Abstract

The results of the present clinical investigation demonstrated that during a 1-year period of healing following surgical crown lengthening, the marginal periodontal tissue showed a tendency to grow in a coronal direction from the level defined at surgery. This pattern of coronal displacement of the gingival margin was more pronounced (P < 0.001) in patients with "thick" tissue biotype and also appeared to be influenced by individual variations in the healing response (P < 0.001) not related to age or gender.
