Edentulous Alveolar Ridge
Conditions
Brief summary
This study aims to conduct a cross-sectional study to compare the differences in clinical indices, patient-reported outcomes, and levels of inflammatory factors in peri-implant gingival crevicular fluid between sites with adequate (≥ 2 mm) and inadequate (\< 2 mm) keratinized mucosa after implant restoration, in order to explore the impact of the presence of keratinized mucosa on peri-implant soft and hard tissue health.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Width of Keratinized Mucosa, KMW | on the day of enrollment | — |
| Plaque Index(PI) | on the day of enrollment | — |
| Bleeding on Probing(BOP) | on the day of enrollment | — |
| Peri-implant Probing Depth(PPD) | on the day of enrollment | — |
| Marginal Bone Loss(MBL) | The X-ray examination will be completed on the day of enrollment | — |
| Patient Satisfaction | on the day of enrollment | visual analogue scale \[VAS\] 0-10,e.g., not at all satisfied to perfectly satisfied |
| Immunological parameters in peri-implant crevicular fluids(PICF) | The PICF will be collected on the day of enrollment | PICF samples were collected from buccal aspects of implants after removing all supragingival plaque. The levels of IL-1β and PGE2 in PICF were measured using a sandwich ELISA kit. |
