Porous Titanium for Dental Implant Applications
Recently, an increasing amount of research has focused on the biological and mechanical behavior of highly porous structures of metallic biomaterials, as implant materials for dental implants. Particularly, pure titanium and its alloys are typically used due to their outstanding mechanical and biological properties. However, these materials have high stiffness (Young’s modulus) in comparison to...
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 کاملprimary placement of titanium peg on hydroxyapatite orbital implant
purpose: to determine the efficacy of primary placement of a titanium sleeve and peg on hydroxyapatite (ha) orbital implants. methods: this retrospective non-comparative interventional case series was performed on 34 patients undergoing enucleation. a standard enucleation technique with primary ha implantation was performed, in which titanium sleeve and peg were placed primarily during the init...
متن کاملElectrochemical preparation of chitosan/hydroxyapatite composite coatings on titanium substrates.
Composite coatings containing brushite (CaHPO(4). 2H(2)O) and chitosan were prepared by electrochemical deposition. The brushite/chitosan composites were converted to hydroxyapatite/chitosan composites in aqueous solutions of sodium hydroxide. The coatings ranged from approximately 1 to 15% chitosan by weight. Qualitative assessment of the coatings showed adhesion significantly improved over th...
