Preparation of Bioactive Titanium Surfaces via Fluoride and Fibronectin Retention
Statement of Problem. The chemical or topographic modification of the dental implant surface can affect bone healing, promote accelerated osteogenesis, and increase bone-implant contact and bonding strength. Objective. In this work, the effects of dental implant surface treatment and fibronectin adsorption on the adhesion of osteoblasts were analyzed. Materials and Methods. Two titanium dental ...
متن کاملBiochemical modification of titanium surfaces: peptides and ECM proteins.
This paper reviews current approaches to the enhancement of bone regeneration at the interface with implant devices, by immobilization of biomolecules to titanium surfaces. In particular, techniques based on surface linking of peptides or extracellular matrix (ECM) proteins are reviewed, trying to describe surface modification approaches and to present results of chemico-physical and biological...
متن کاملMinor Role of Plasminogen in Complement Activation on Cell Surfaces
Atypical hemolytic uremic syndrome (aHUS) is a rare, but severe thrombotic microangiopathy. In roughly two thirds of the patients, mutations in complement genes lead to uncontrolled activation of the complement system against self cells. Recently, aHUS patients were described with deficiency of the fibrinolytic protein plasminogen. This zymogen and its protease form plasmin have both been shown...
متن کاملEndothelialization of Titanium Surfaces
In the extracellular matrix (ECM), chemical cues are present that control all aspects of cell biology. These surfacebound and soluble factors provide the necessary adhesion and signaling for normal cellular activity, and without such matrix support, the cells will quickly apoptose. Implanted device surfaces lack the molecular features that provide guidance to the surrounding cells to afford opt...
متن کاملTitanium dental implant surfaces
Osseointegration has been defined as “a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant”. However, titanium and its alloys cannot directly bond to living bone after being implanted into the body. The osseointegration of titanium dental implants is critically dependent on the implant surface properties. Various surface modificat...
