An alternative prosthetic treatment approach for single implants in the maxillary esthetic zone with an improper implant axis, limited interocclusal distance, inadequate abutment retention, and screw holes located at the labial surface is presented in this clinical report. The gingiva and soft tissues were contoured with provisional composite restorations to mimic the emergence profile of lateral incisors. Prefabricated zirconia abutments were customized with laminate veneer preparations by appropriate ceramic build-up with reference from the reshaped gingiva to avoid labiolingual overcontour. The laminate veneers were fabricated by computer-aided design/computer-assisted manufacture to cover the screw hole of the angulated abutment at the labial surface. Preliminary results revealed improvement in esthetics; however, long-term clinical follow-up should be performed.
