Cementum Matrix Extract Extract And Promote Gingival Fibroblasts, Osteoblasts On The Titanium Surface Adhesion And Migration Of Experimental Research

The osseointegrated implants have been gradully accepted in worldsince Branemark implant had been invented. Moreover,they already were widly used in clinic becouse of their highly successful rate. there are two interface between titanium endosseous implant and tissue: 1.implant—bone interface interface,2.implant— soft tissue interface. These interfaces play important role in implantol using. The direct anchorged living remodeling bone provides mechanical stablity for implanted denture. And the biological seal around the neck of implant could resist dregs of meal remaining and bacterium invading, in order to prevent from inflammatory infiltration, downgrowth of epithelium,formation of a preiodontal pocket, destruction of the supporting bone that result in eventual implant failure and decrease the service life of osseointergrated implant.For improve the quality of osseous interface between the dental implant and bone, the treatments of implant surface have been frequently used, for example, the sprayed titanium surface with hydroxyapatite or titanium plasma,etched and sandblasted titanium surface.These means not only greatly increase the connected space between the dental implant but also enchance their affinity. When scholars are paying their attantion to the biological coating materials of implant surface, some international and national research workers chose bone morphogenetic protein(BMP) to improve osteoblasts growth on titanium surface and increase the area osteointergrated interface. Meanwhile, the implant— soft tissue interface is a knoty problem in the field of reseach in implantology. Although the ideal implant material for soft tissue cells adhesion would be polished titanium...
