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...
متن کاملResearch 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...
متن کاملChemical interaction between titanium implant surface and amino acids.
The purpose of this study was to investigate the chemical interaction between titanium implant surface and amino acids. Pure titanium disks were pretreated with 10 N HCl and ultrapure water at room temperature for 30 minutes each. Disks were then modified with one of the three amino acids--L-aspartic acid, L-serine, or L-threonine--at 37 degrees C for 12 hours. Modification with oxalic acid was...
متن کاملTorque Analysis of a Triple Acid-Etched Titanium Implant Surface
The present study aimed to evaluate the removal torque of titanium implants treated with triple acid etching. Twenty-one rats were used in this study. For all animals, the tibia was prepared with a 2 mm drill, and a titanium implant (2 × 4 mm) was inserted after treatment using the subtraction method of triple acid etching. The flaps were sutured. Seven animals were killed 14, 28, and 63 days a...
متن کاملSurface 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...
