Clinical trials

This study aims to combine real-world research with relevant bone repair materials and techniques to improve alveolar bone resorption in extraction sockets following impacted wisdom tooth removal, while achieving effective bone preservation or promoting bone regeneration. All eligible cases within specified parameters will be included in the clinical study scope. Based on real-world clinical data, we will proactively collect postoperative clinical examination findings and imaging data. Statistical analysis will be performed on clinical outcomes and follow-up data from patients undergoing mandibular impacted M3 extraction. The study aims to clarify the therapeutic efficacy of the thermosensitive hydroxyethylchitosan-loaded concentrated growth factor group in repairing mesial bone defects of M2s following M3 extraction.

This study aims to explore the dynamic changes in different cell types and their molecular regulatory mechanisms during the healing process of peri-implant soft tissues, using single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST). The research will focus specifically on the healing of soft tissues around dental implants in human subjects with the use of a healing abutment. Participants in the healing abutment group will have a micro healing abutment placed immediately after implant placement. Tissue 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. Spatial 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. This combined approach will allow for a comprehensive characterization of cellular interactions, spatial gene expression patterns, and regulatory networks specific to healing abutments. The goal is to identify key regulatory factors that could improve peri-implant soft tissue healing and help prevent peri-implantitis.

This study aims to evaluate the clinical effectiveness of biomimetic abutments in implant restoration.
