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.

Immunological parameters in peri-implant crevicular fluids(PICF)
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.
Time frame: The PICF will be collected on the day of enrollment
