Similarly, the mean probing depths (mean values of measurements taken at four peri-implant sites), measured using a millimetric probe, were categorised as: 0 mm; 0-3 mm; or + 3 mm. At the first follow up, at six months, 108 implants showed a mean probing depth of 0 mm, 90 had a probing depth of 0-3 mm, while in no case was the mean probing depth found to be greater than 3 mm. At one year, the number of implants with a mean probing depth of 0-3 mm had risen to 154, while 42 continued to show no probing depth and only two recorded a mean depth greater than 3 mm. At the two-year follow up, the number of implants with a probing depth of 0-3 mm had further risen to 161, while 23 still recorded no probing depth and a small number (n=14) had a probing depth greater than 3 mm (Fig. 4.2).

Fig. 4.2 • Mean probing depth of four peri-implant sites.

The quantity of peri-implant keratinised gengival tissue, measured on the vestibular surface using a millimetric probe, was categorised as: 0 mm; 0-3 mm; or + 3 mm. At the first follow up, at six months, 144 implants showed between 0 and 3 mm of keratinised tissue, 44 showed more than 3 mm, and only 10 were free of keratinised gingival tissue. At one year, the number of implants with at least 3 mm of keratinised gingival tissue had risen to 115, while 72 showed between 0 and 3 mm, and only 11 had no keratinised gingival tissue. At the two-year follow up, the number of implants with at least 3 mm of keratinised gingival tissue had further risen to 158, while 33 had less than 3 mm of adherent gingiva and seven showed no keratinised gingival tissue (Fig. 4.3).
