在人体中,牙齿是唯一穿通上皮组织的结构.种植体作为天然牙的人工替代物,因此,也具备了有别于其他种植体的特殊性,即具有穿粘膜特性(transmucosalpenetration).种植体植入机体后分别与软、硬组织形成种植体-软组织和种植体-骨组织两个界面.以往研究者对种植体-骨组织界面的研究较深入,所谓“骨融合式种植体”(osseointegrated implant)均指骨组织界面而言.但近年研究表明:种植体-软组织界面对于保护其根部骨结合界面的长期稳定,使之免受口腔中有害物质的侵袭,同样具有重要作用.理想的种植体-牙龈组织界面结合形式应具有类似天然牙上皮附着的结构,
In the human body, the tooth is the only structure that penetrates the epithelial tissue.As an artificial substitute for natural teeth, the implant also possesses the peculiarity of other implants that it has transmucosalpenetration. The two interfaces of implant-soft tissue and implant-bone tissue were formed with soft and hard tissues respectively after penetrating into the body.Past researchers have done a lot of researches on implant-bone interface, the so-called osseointegrated implants ) Both refer to the bone tissue interface, but in recent years, studies have shown that implant-soft tissue interface plays an important role in protecting the long-term stability of its root bone-binding interface from the harmful substances in the oral cavity.The ideal implant- Gingival tissue interface should have a similar form of natural tooth epithelium attached to the structure,
