Treatment of Cement-Associated Peri-Implantitis Using Tetracycline and Enamel Matrix Derivative: A Case Report

Introduction: This case report describes the treatment of peri-implantitis around a restored single-unit implant. Case Presentation: Clinical findings included deep probing depths (PDs), bleeding on probing (BOP), and suppuration. Radiographs suggested crater-like bone loss. The area was surgically treated via an access flap. The peri-implant defect was associated with cement that was found below the cement-retained permanent restoration. The cement was removed, and the implant was treated with tetracycline and enamel matrix derivative (EMD). After an uneventful 10-month period of healing, there was a significant reduction in PD and absence of BOP and suppuration. In addition, there was radiographic evidence of new bone formation. Conclusion: This case report proposes a new technique for treating peri-implantitis and a new application for EMD.
