Abstract

|
In the anterior region, osteotomy for clinical crown lengthening procedure is hesitated because of esthetic point of view. Even in premolar area, osteotomy could not be recommended considering crown to root ratio after the crown lengthening procedure. Better crown to root ratio is anticipated after surgical extrusion procedure compared with osteotomy. Surgical extrusion was performed by atraumatic extraction technique in this case report. Full thickness mucoperiosteal flap were raised. The tooth were luxated carefully by periotome and extruded. It was stabilized with interrupted sutures. Mobility decreased after 1months. The tooth had been maintained without any specific clinical & radiographic findings of bone loss or ankylosis during 2 years. Atraumatic extraction and preservation of the PDL is considered as one of the most important keys for successful treatment outcome.
