The Use of a Coded Healing Abutment in the Restoration of a Single, Immediately Placed Implant in the Esthetic Zone: A Clinical Case Report

For several years, the implant-level impression procedure started by removal of the healing abutment, followed by connection of the impression coping to the implant. Encode Complete (Encode, Biomet 3i, Biomet 3i, Palm Beach Gardens, FL) was introduced to eliminate implant-level impressions by offering a healing abutment-level impression protocol. This report illustrated the treatment of a single tooth in the anterior esthetic zone using Encode Complete. A 23-year-old female patient reported to the prosthodontics clinic complaining of a fractured maxillary anterior tooth that was deemed nonrestorable. After immediate implant placement, soft tissue preservation and temporization of the implant, healing abutment level impression was made. The codes embedded on the occlusal surface communicated the implant depth, hex-orientation, platform diameter, and interface. The definitive Encode gold-plated titanium abutment was anatomically designed virtually with customized margin, contour, taper, and emergence profile. The milling process was initiated, and the virtual design data were sent to the Robocast Center for analog placement in the original Encode master cast. The definitive abutment was placed on the master cast using Robocast technology, followed by the fabrication of the final porcelain fused to zirconia cement-retained all ceramic crown. The abutment was secured to the implant with a Gold-Tite abutment screw, followed by the final cement-retained implant crown placement. Recall visits were obtained at 1 week, 1 month, 3 months, and 1 year after final prosthesis insertion.
