Single Implant Restoration for Replacement of Extensively Damaged Maxillary Lateral Incisor using Two - Stage Surgical Protocol: A Clinical Report

The replacement of a single anterior tooth in esthetic zone is a challenging treatment. This report describes the replacing of extensively damaged maxillary right lateral incisor using an implant - supported restoration. After clinical and radiographic examination, the decision was made to extract the tooth and replace it with an implant. Therefore, tooth was atraumatically extracted then the alveolar ridge was attempted to preserve by using platelet - rich fibrin (PRF). Implant placement was delayed for 6 months due to the existence of the periradicular infection. Therefore, acrylic resin - bonded prosthesis as a transitional restoration was made to restore the esthetic and function during this period. A 3.25 mm diameter implant (Biomet3i) was placed after the healing of the area with allograft bone augmentation and resorbable membrane simultaneously. The tissues were approximated and sutured over the implant using the two - stage surgical protocol. After3 months, the implant uncovered, and the soft tissue was contoured with provisional restoration before the definitive impression making. Cement - retained all ceramic crown with a customized titanium abutment were used as a definitive restoration.1 - year after completing the treatment, no evidence of marginal bone loss or any other signs or symptoms of failure were found.
