Enhancement of Surface Wettability via the Modification of Microtextured Titanium Implant Surfaces with Polyelectrolytes

Surface chemistry effects of topographic modification of titanium dental implant surfaces: 1. Surface analysis.

PURPOSE To analyze the surface composition of 34 different commercially available titanium dental implants. MATERIALS AND METHODS Surface composition was evaluated by x-ray photoelectron spectroscopy (XPS). Samples were divided into 4 groups, depending on their surface topography (machined, sandblasted, acid etched, or plasma sprayed). RESULTS Statistical analysis of the data showed a clear...

New surface modification of titanium implant with phospho-amino acid.

The purpose of this study was to investigate a new biochemical surface modification technique for titanium implants using phospho-amino acid. Pure titanium disks were pretreated with 10 N HCl and ultrapure water at room temperature for 30 minutes respectively. Then these disks were modified with either L-threonine (Thr) or O-phospho-L-threonine (P-Thr) at 37 degrees C for 12 hours. X-ray photoe...

Research Progress on the Biochemical Modification of Titanium Implant Surface

Nowadays, artificial implants, a third denture of human, can maximize the chewing efficiency of patients with missing teeth, delay the absorption of alveolar bone and improve the quality of life. Osseointegration of the interface between the bone and implants, introduced first by Branemark et al. [1,2], is the most determining factor in oral clinical implant applications. As the main material i...

Wettability studies of topologically distinct titanium surfaces.

Biomedical implants made of titanium-based materials are expected to have certain essential features including high bone-to-implant contact and optimum osteointegration, which are often influenced by the surface topography and physicochemical properties of titanium surfaces. The surface structure in the nanoscale regime is presumed to alter/facilitate the protein binding, cell adhesion and prol...
