The Single-Unit Abutment (SUA) is designed for single-tooth restorations placed at time of surgery. The concave profile of the SUA enables increased volume of soft tissue, facilitating an uninterrupted seal. The SUA reduces soft-tissue disruption that may cause apical migration of epithelial cells, potentially creating pockets of unstable soft tissue. The concept of a final abutment at time of surgery helps promotes bone maintenance and greater aesthetic outcomes.
