Outcome measures
PD, tooth
PLAQUE
Six sites per implant (mesiobuccal, buccal, distobuccal, distolingual, lingual and mesiolingual) and the neighboring teeth/implant(s) and contralateral tooth or implant sites were assessed for clinical measurements using a periodontal probe (UNC-15, Hu-Friedy, Chicago, IL, USA) at each follow-up appointment. All measurements were performed by examiners not involved into the clinical therapy. One single examiner performed the 10-year follow-up examinations, after a calibration process for clinial trials at the Clinic of Reconstructive Dentistry, University of Zurich. The variables examined are listed as follows:Probing depth (PD, mm)Bleeding on probing (BOP, %) [Plaque control record (PCR, %) [Outcome measures were assessed at implant insertion (TStandardized periapical radiographs of all implants were taken using a paralleling technique with Rinn-holders at T
