Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change From Baseline in Peri-Implant Marginal Bone Level at Final Follow-up | Baseline (prosthesis delivery), 6 months after loading, and final follow-up (12 to 24 months after loading) | Vertical distance (mm) from the bone crest to the first implant thread, measured at the mesial and distal sites on standardized periapical radiographs (long-cone paralleling technique) with calibrated ImageJ software by two blinded examiners. Change is calculated as the baseline value minus the follow-up value; positive values indicate bone loss. |
| Secondary | Interleukin-1β Concentration in Peri-Implant Crevicular Fluid | 12 months after loading | IL-1β concentration (pg/mL) in peri-implant crevicular fluid collected with sterile paper points (20 s) and analysed in duplicate by ELISA. Values below the detection limit (0.4 pg/mL) were set at half the detection limit for analysis. |
| Secondary | Matrix Metalloproteinase-8 Concentration in Peri-Implant Crevicular Fluid | 12 months after loading | MMP-8 concentration (ng/mL) in peri-implant crevicular fluid collected with sterile paper points (20 s) and analysed in duplicate by ELISA. Values below the detection limit (0.1 ng/mL) were set at half the detection limit for analysis. |
