Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Peri-implant Bleeding on Probing | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Bleeding on probing will be assessed during peri-implant probing using a periodontal probe. Peri-implant probing is performed at six sites around each implant-supported restoration: mesiobuccal, mid-buccal, distobuccal, mesiolingual/palatal, mid-lingual/palatal, and distolingual/palatal sites. Bleeding following probing will be recorded and used as an indicator of peri-implant soft-tissue inflammation. |
| Secondary | Peri-implant Probing Depth | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Probing depth is measured from the peri-implant soft-tissue margin to the bottom of the sulcus using a UNC-15 periodontal probe with approximately 0.25-g probing force at six sites around each implant. |
| Secondary | Peri-implant Crevicular Fluid Inflammatory Biomarker Levels | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Levels of IL-1β, IL-6, TNF-α, MIP-1α, MMP-8, and MMP-9 in peri-implant crevicular fluid will be quantified using ELISA. |
| Secondary | Subgingival Microbial Composition | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Subgingival plaque samples collected from peri-implant sites will be analyzed using 16S rRNA-based methods to characterize microbial composition. |
| Secondary | Marginal Bone Level Change | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Marginal bone level will be measured on standardized parallel periapical radiographs. The most coronal implant-to-bone contact will be used to define the marginal bone level, and longitudinal changes will be assessed. |
| Secondary | Buccal Peri-implant Soft-Tissue Height Change | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Serial intraoral scans from the same participant will be superimposed to quantify changes in buccal peri-implant soft-tissue height. |
| Secondary | Interdental Papilla Height Change | Approximately 6 months, 1 year, 2 years, and 3 years after definitive restoration placement | Serial intraoral scans will be superimposed to measure longitudinal changes in peri-implant papillary height. |
