3 Berglundh et al., 2002
PPD > 6 mm in combination with bleeding on probing/ 2.5 6 suppuration and attachment loss/bone loss of 2.5 mm
5 Lang and Berglundh 2011:
Changes in the level of the crestal bone in conjunction with bleeding on probing with or without concomitant deepening of peri-implant pockets. Pus is a common finding in peri-implantitis sites.
