Clinical Trial: Evaluation of the Prevalence and Risk Factors for Patients With Peri-implant Disease
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational [Patient Registry]
Official Title: The Prevalence and Risk Factors for Patients With Peri-implant Disease: A Prospective Study
Brief Summary: To investigate the prevalence and risk factors for peri-implant disease in partially edentulous patients rehabilitated with implants supported crown or bridge so as to provide evidence for clinical prevention and control.
Detailed Summary: The aim of the present study is to identify the prevalence of peri-implant disease in partially edentulous subjects treated with osseointegrated implants, using clinical parameters, as well as to analyse the possible disease association with demographic, behavioural, and biological risk variables.
Sponsor: Fourth Military Medical University
Current Primary Outcome: peri-implant disease [ Time Frame: at the 5 years after prosthetic loading. ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Gingival Bleeding on Probing [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]Gingival bleeding on probing (BOP) using the modified sulcus bleeding index for implants. Scale equals 0 = No bleeding when periodontal probe is passed along the gingival margin;1 = Isolated bleeding spots visible;2 = Blood forms a confluent red line on the gingival margin;3 = Heavy or profuse bleeding.
- Pocket depths [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]PD will be measured from the free gingival margin to the base of the pocket and will be recorded in whole millimeters (mm).
- Marginal bone loss [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]Marginal bone loss will be assessed by periapical radiographs taken with the paralleling technique.
Original Secondary Outcome: Same as current
