Porous 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 کاملTitanium microbead-based porous implants: bead size controls cell response and host integration.
Openly porous structures in implants are desirable for better integration with the host tissue. Sintered microbead-based titanium implants for oto-rhinolaryngology applications, which create an environment where the cells can migrate in the areas between the microbeads, are developed. This structure promotes fibrovascular tissue formation within the implant in vivo. In this study, it is determi...
متن کاملSusceptibility of various cell lines to Neospora caninum tachyzoites cultivation
Neospora caninum is a coccidian protozoan parasite which is a major cause of bovine abortions and neonatal mortality in cattle, sheep, goat and horse. Occasionally, cultured cells are used for isolation and multiplication of the agent in vitro with several purposes. In this study the tachyzoite yields of N. caninum were compared in various cell cultures as the host cell lines. Among the cell cu...
متن کاملThe effect of hydroxyapatite coating on bone growth into porous titanium alloy implants.
In rabbits and goats, test implants with a porous surface of two layers of Tl-6A;-4V beads were examined at intervals for bond strength with bone. Half of the implants were coated with hydroxyapatite by plasma spray. The bonding strength with bone in the coated specimens was about four times greater than that of the uncoated specimens at two weeks, and twice as strong at six weeks. Twelve weeks...
متن کاملOsseointegration 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...
