The success of autotransplantation depends on the viability of periodontal ligament in the transplanted tooth. Mechanical injury to periodontal tissues frequently results in dental root resorption and ankylosis, which leads to the failure of transplantation. Enamel matrix derivative(EMD) Which contains several enamel matrix protein (amelogenin family) has been reported to be effective in some periodontal therapies has been recently used to in-duce periodontal regeneration. EMD promotes proliferation of periodontal ligament cells and is suggested to be useful for transplantation.
In this case, we report a clinical case of EMD application in the transplantation of an impacted and immature tooth of a 14 year-old girl to enhance the periodontal regeneration.
