Abstract

Purpose: Various methods are used in clinical crown lengthening procedure, Esthetic is more important in anterior region than in posterior region. Therefore when performing clinical crown lengthening procedure in esthetic region, clinicians should choose method which doesn't impair esthetic. Surgical extrusion could be a good method to achieve esthetic results. Material and Methods: Two patients were scheduled to clinical crown lengthening procedure in esthetic region. Teeth were extruded with periotome carefully to the intended level. Extruded teeth were anchored with sutures. Sutures are removed after 7day. Restorations were seated after extruded teeth were stabilized. Result: Five to six months later, both cases showed favorable esthetic outcome that were harmonious with adjacent teeth. Conclusion: When clinicians are to do clinical crown lengthening procedure in esthetic region, predictable esthetic outcome could be achieved with surgical extrusion.
