Prosthetic considerations and strategies for single tooth implants in the aesthetic zone: a review

Abutment contours, position, tissue thickness, and volume are all key parameters for the successful restoration of implants in the aesthetic zone. This is particularly true for patients with high smile lines and high aesthetic expectations. This narrative review will provide a synopsis of the known science of implant abutments and peri-implant tissues in this area and cover specialised techniques, materials, and protocols to improve outcomes with increased predictability. Special attention will be given to the use of provisionals and custom healing abutments for the preservation and shaping of the peri-implant tissues.
