A long-term prospective cohort study on immediately restored single tooth implants inserted in extraction sockets and healed ridges: CBCT analyses, soft tissue alterations, aesthetic ratings, and patient-reported outcomes.

Substantial dimensional changes may be expected at the buccal aspect of single implants inserted in the premaxilla. As a result, contour augmentation procedures at the time of implant placement should be considered to counteract these bone alterations, even when implants are fully embedded in bone upon insertion.
