Both neighbouring teeth had to be present at re\u2010examination and baseline clinical photographs (within the first year of function) had to be available for soft tissue evaluation.

However, neighbouring teeth demonstrated midfacial recession and eruption pointing to a major distortion with the implant crown (&gt;\u00a01\u00a0mm) in 5\/24 (21%) and 10\/24 (42%) of the cases, respectively. Baseline aesthetics was considered poor (mean Pink Esthetic Score 7.42, mean White Esthetic Score 5.43), yet a significant time effect could not be demonstrated (<jats:italic>p<\/jats:italic>\u00a0\u2265\u00a00.552).
