Surgical Crown Lengthening – Indications and Techniques

Dr. Jan Behring, Hamburg/Germany, shows the various techniques used in surgical crown lengthening on a porc jaw. He demonstrates possible alternatives, too, and discusses the particular importance of biologic width in surgical crown lengthening. After preparation of the access to the alveolar bone and removal of excess soft tissue a flap elevation and the circular reduction of the bone level is performed by piezotome. Dr. Behring does the ostectomy in sufficient distance to the tooth. This is how he protects the desmodontal parts which is the condition for intact tissue attachment. Osteoplasty and manual scaling of the root surface are following. The coronal parts of the desmodont are removed, above the newly created bone level a 1-mm-band of root cement is left. If it was left completely a soft tissue proliferation in coronal direction would be the undesired consequence of this surgical procedure.
