Evaluation of the Prevalence and Risk Factors for Patients With Peri-implant Disease：a Retrospective Study
- Conditions
- Jaw, Edentulous, Partially
- Registration Number
- NCT02662361
- Lead Sponsor
- Air Force Military Medical University, China
- Brief Summary
To investigate the patient-related 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 Description
Objective: To investigate the patient-related 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. Methods:A total of 131 patients will enroll in the study. Univariate and multivariate logistic regression analysis is used to determine the patient factors associated with peri-implant disease. The variables include age, gender, smoking and alcohol consumption, presence of diabetes, cardiovascular disease, osteoporosis, bruxism, bleeding upon brushing, reason for extraction, oral hygiene and periodontal status.

Patients implanted at least one implant and restored with implant-supported fixed partial dentures and single crowns.
The implant-supported fixed partial dentures and single crowns were in function at least one year.
Jaw radiotherapy treatment before and after implanting. Patients who have bruxism, xerostomia or the adjacent teeth periapical periodontitis.
Patients who suffered with oral mucosa disease,or aggressive periodontitis or jaw defect.
Patients who suffered with mental and psychological disease will influence their oral health normal maintenance.
Study & Design

- OBSERVATIONAL
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Survival of implants at the first return visit（at least one year after restoration） Time from the surgical placement of implants until the first return visit（at least one year after restoration）
- Secondary Outcome Measures
Name Time Method Gingival Bleeding on Probing at the first return visit（at least one year after restoration） 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 at the first return visit（at least one year after restoration） Pocket depths measured around implants in millimeter (mm)
Marginal bone loss at the first return visit（at least one year after restoration） Time from the surgical placement of implants until the first return visit（at least one year after restoration）
