PLCBL was defined as a reduction \u2a7e0.5\u00a0mm and severe PLCBL (primary variable) as a reduction \u2a7e1.5\u00a0mm in mesial and\/or distal bone level, measured from the day of implant placement to uncovering or abutment installation\/crown delivery. The incidence of PLCBL and patient and implant variables were recorded.
