Brief Summary
The goal of this multicenter cross-sectional study is to investigate the prevalence of peri-implantitis in China. The main questions it aims to answer are:
- What is the prevalence of peri-implantitis in China
- What are the risk indicators of peri-implantitis in China Participants will be invited to a free-of-charge clinical and radiographic examination of conventional dental implants present for over 5 years.

Outcome Measures
Primary Outcomes (3)
Bleeding on probing [positive (+) or negative (-)]
When bleeding is present after probing using a periodontal probe with a force of 0.2-0.3 N.
About 5-10 years after surgery
Peri-implant probing depth (mm)
Measured using a periodontal probe inserted into the peri-implant sulcus
About 5-10 years after surgery
Bone loss (mm)
Measured apically from the most coronal portion of the intraosseous part of the implant using periapical radiographs
About 5-10 years after surgery
Study Arms (1)
Patients
Patients having at least one rough surface titanium implant in function for more than 5 years.
