Conditions
Summary
The aim of the diagnostic accuracy study was to compare the diagnostic accuracy of probing depth before (PPD-1) and following (PPD-2) the removal of prothesis in identifying the presence of peri-implantitis and assess the factors influencing peri-implant probing.

Interventions
Before removal of the prosthetic reconstruction: * Measurement of PPD-1: The PPDs at 6 site were measured as the distance from the mucosal margin to the base of the peri-implant pocket. * Measurement of BOP-1：Bleeding sites after gentle probing within 15s were recorded as BOP scores. A positive score (1 point) was recorded if bleeding was observed during either of probing assessment by two researchers. After removal of the prosthetic reconstruction, PPD-2 and BOP-2 were recorded following the same protocol.
