Participants in the healing abutment group will have a micro healing abutment placed immediately after implant placement.\n\nTissue samples will be collected at various time points (Day 4, Day 14, and Day 70) to construct a detailed single-cell map of the healing process.\n\nSpatial transcriptomics will be integrated to preserve tissue architecture, enabling the identification of the spatial distribution of different cell types and their interactions within the peri-implant microenvironment.\n\nThis combined approach will allow for a comprehensive characterization of cellular interactions, spatial gene expression patterns, and regulatory networks specific to healing abutments.\n\nThe goal is to identify key regulatory factors that could improve peri-implant soft tissue healing and help prevent peri-implantitis.",[27],"Peri-implant Soft Tissue Healing",[29,30],"Peri-implant soft tissue healing","scRNA-seq","NOT_YET_RECRUITING","2025-12-13",{"date":34,"type":35},"2025-12-16","ACTUAL",{"date":37,"type":21},"2025-12-20",{"date":39,"type":21},"2026-12-31",{"name":41,"class":42},"Stomatological Hospital Affiliated with Fujian Medical University","OTHER"]
