Clinical measurements Baseline measurements at the included implant site were performed on the same day as the surgical procedure. All probing measurements were obtained with a pressure (0.20-0.25N) sensitive probe (Click-Probe®, Kerr, Switzerland) to the nearest mm at 6 sites per tooth/implant (mesio-buccal, buccal, disto-buccal, disto-palatal, palatal, mesio-palatal).
