Overview
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.
Description
This study aims to design a diagnostic accuracy study to compare the peri-implant probing depth and bleeding on probing before and after crown removal. It will explore the impact of prosthetic design on the accuracy of peri-implant probing and its diagnostic accuracy, and provide clinical recommendations on whether the prosthesis should be removed prior to peri-implant probing.
Eligibility
Inclusion Criteria:
- Age greater than 18 years.
- The implant has completed osseointegration and has undergone final restoration for at least one month.
- The final restoration needs to be removed or retrieved for various reasons.
Exclusion Criteria:
- Patients with serious systemic diseases, severe intraoral infections, severe mental disorders, pregnancy/lactation in women, or other conditions that make oral treatment operations unsuitable.
- History of crown removal or re-restoration within the past month prior to the visit.
- The prosthesis has fallen off or is severely damaged and has lost its original form before the visit.
- The prosthesis cannot be completely removed.
- Refusal to participate in this study.
