Cytocone Procedure: Conservative Repair of a Buccal Plate Dehiscence in Preparation for Implant Placement.

In type II sockets, the soft-tissue level is at or coronal to the cementoenamel junction, and part of the buccal plate is missing. In the esthetic zone, a patient with this type of situation often is not a good candidate for immediate implant placement until the osseous defect is repaired. Therefore, use of a conservative regenerative procedure to repair such a defective socket would be advantageous. The Cytocone procedure utilizes a nonresorbable dense polytetrafluorethylene (d-PTFE) barrier and modifies the classic "ice cream cone" technique to restore a buccal osseous defect without raising a labial flap. This article describes and illustrates the Cytocone procedure.
