Clinical and radiographic recordings
PD, bleeding, tooth
SUPPURATION, BLEEDING, PLAQUE
Prior to treatment, the following clinical parameters were collected at baseline and at 6, 12 months by author ML masked to treatment assignments:
PD: distance (mm) from the implant mucosal margin to the probable base of the pocket at six sites per implant (mesio-buccal, buccal, disto-buccal, disto-palatal/lingual, lingual/palatal, mesio-lingual/palatal).BoP: bleeding on gentle probing to the base of the pocket at six sites per implant (mesio-buccal, buccal, disto-buccal, disto-palatal/lingual, lingual/palatal, mesio-lingual/palatal).Full mouth plaque scores recorded as the percentage tooth and implant surfaces with a visible plaque at four sites per tooth/implant (mesial, distal, buccal, and lingual/palatal) following staining with disclosing solution. As a supplement, the probe was used to record presence or absence of plaque at test and control sites.Width of keratinized mucosa at baseline as the distance (mm) from the mid-buccal mucosal margin to the mucogingival junction at each implant.Presence of suppuration (SUP) after gentle probing to the base of the pocket at six sites per implant (mesio-buccal, buccal, distobuccal, disto-palatal/lingual, lingual/palatal, mesio-lingual/palatal.Clinical recordings were performed using a plastic replacement tip (Colorvue™ Probe, Hu-Friedy, Chicago, IL, USA) with 3–6-9–12 mm markings connected to a satin surfaced steel handle (Colorvue™ Prote Handle (PH6), Hu-Friedy, IL, USA). CBL was recorded from intraoral digitalized radiographs captured using customized radiographic holders (Eggen-holder) and long-cone parallel technique [
