Successful Management of Peri-Implantitis around Short and Ultrashort Single-Crown Implants: A Case Series with a 3-Year Follow-Up

Table 2

Clinical parameters of the implant population. PD: probing depth; REC: recession; m-BI: modified bleeding index; mPLI: modified plaque index; av-BD: average bone defect depth; m-BD: mesial bone defect depth; d-BD: distal bone defect depth; m-Angle: mesial angle of defect; d-Angle: distal angle of defect; KT: keratinized tissue; FM-BoP: full-mouth bleeding on probing; FM-VPI: full-mouth visible plaque index; Q-sites: deepest site; deep pockets: PD ≥ 6.0 mm.
