Biologically oriented preparation technique for surgically extruded teeth: A clinical report.

Surgical extrusion allows a ferrule to be obtained without the use of orthodontic extrusion or the need to remove hard and soft tissues. However, after the healing period, the soft tissue of the extruded tooth might become thinner, creating an unesthetic gingival margin. Unlike other preparation techniques, the biologically oriented preparation technique provides increased long-term gingival thickness. This article describes the treatment of 3 patients with teeth with no ferrule that were surgically extruded and restored with the biologically oriented preparation technique .
