NCT06208254

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)
