The Composite-And-Chain™ Extrusion Kit

The current technique for attaching a gold extrusion chain to an impacted tooth for the purpose of extrusion involves bonding a mesh-based eyelet or bracket to the target tooth. Depending upon surgical accessibility, often the mesh base doesn’t fit flat against the exposed surface tooth anatomy, which can result in a weak bond and possible failure. This failure can require a repeat of the surgical procedure to re-bond the attachment to the tooth. Later, when the tooth has been extruded, the eyelet or bracket must be removed. The type of attachment is typically removed by pinching the base to fracture the composite bond to the metal mesh. This process can be very painful for the patient because these teeth have a tendency to be particularly sensitive. At times, the entire metal attachment needs to be ground away and this can be both time consuming for the dentist and uncomfortable for the patient.
