Cohort study 

研究目的:

本课题组提出帽兜技术,即微创拔牙后,利用牙槽窝内的反应性软组织辅助关闭创口,并以前瞻性队列研究的方法分为反应性软组织组及异种胶原基质组,观察后期骨组织再生和角化龈宽度。且透过实验室方法进行相关检测,进一步阐明微环境改变的机制,包括细胞亚群的改变、细胞转录组的差异、蛋白表达的影响等  

Objectives of Study:

The research group put forward an improved technique for periodontally compromised sites,which is called Hood Technique.After minimally invasive extraction,the reactive softtissue in the extraction socket is not removed,but lifted to assist the wound closure.At the same time,the cohort study is designed and the patients are divided into reactive soft tissue group and xenogeneic collagen matrix group to observe the bone and soft tisssue regeneration in the later period.The mechanism of microenvironment change,including the change of cell subpopulation,the difference of cell transcriptome and the effect of protein expression,was further elucidated by laboratory method.
