Osseointegration of porous titanium implants with and without electrochemically deposited DCPD coating in an ovine model
BACKGROUND Uncemented fixation of components in joint arthroplasty is achieved primarily through de novo bone formation at the bone-implant interface and establishment of a biological and mechanical interlock. In order to enhance bone-implant integration osteoconductive coatings and the methods of application thereof are continuously being developed and applied to highly porous and roughened im...
متن کاملPorous Structure Characterization in Titanium Coating for Surgical Implants
Powder metallurgy techniques have been used to produce controlled porous structures, such as the porous coatings applied for dental and orthopedic surgical implants, which allow bony tissue ingrowth within the implant surface improving fixation. This work presents the processing and characterization of titanium porous coatings of different porosity levels, processed through powder metallurgy te...
متن کاملThe nanostructure of an electrochemically deposited hydroxyapatite coating
a r t i c l e i n f o The structure of an implant's coating can significantly affect its physical and chemical properties, and eventually – its clinical performance. In this paper, the nanostructure of an electrochemically deposited hydroxyapatite (EDHA) coating was studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTE...
متن کاملSimple application of fibronectin–mimetic coating enhances osseointegration of titanium implants
Integrin-mediated cell adhesion to biomolecules adsorbed onto biomedical devices regulates device integration and performance. Because of the central role of integrin-fibronectin (FN) interactions in osteoblastic function and bone formation, we evaluated the ability of FN-inspired biomolecular coatings to promote osteoblastic differentiation and implant osseointegration. Notably, these biomolec...
متن کاملPaired evaluation of calvarial reconstruction with prototyped titanium implants with and without ceramic coating.
PURPOSE To investigate the osseointegration properties of prototyped implants with tridimensionally interconnected pores made of the Ti6Al4V alloy and the influence of a thin calcium phosphate coating. METHODS Bilateral critical size calvarial defects were created in thirty Wistar rats and filled with coated and uncoated implants in a randomized fashion. The animals were kept for 15, 45 and 9...
