About this study

Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| no peri-implant disease | The subjects who did not suffer from peri-implant disease. | |
| peri-implant disease | The subjects who suffered from peri-implant disease. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Survival of implants
Time from the surgical placement of implants until the first return visit（at least one year after restoration）
Measured: at the first return visit（at least one year after restoration）
Secondary outcomes (3)
Gingival Bleeding on Probing
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.
Measured: at the first return visit（at least one year after restoration）
Pocket depths
Pocket depths measured around implants in millimeter (mm)
Measured: at the first return visit（at least one year after restoration）
Marginal bone loss
Time from the surgical placement of implants until the first return visit（at least one year after restoration）
Measured: at the first return visit（at least one year after restoration）

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02662361, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
