چکیده

Abstract In bone tissue repair, metallic implants like screws, pins, plates, stents are considered as boon for patients but it has the disadvantage of being a foreign body and can never get absorbed or converted to bone. These serve purpose often temporarily, fails attain mechanical, elastic properties near that normal human bones. To circumvent these drawbacks, preparation nanobioglasses having titanium different proportions fluoride using melt quenching method is reported. The physical, thermal, materials were characterized by their densities, thermal transitions, moduli ultrasonic study. in vitro degradation bioactivity assessed immersion simulated fluid (SBF). hydroxyapatite(HAp) formation was variation pH over 21 days its presence confirmed FTIR, XRD, SEM, EDS. Human osteo sarcoma MG‐63(ATCC‐1427), SAOS‐2(ATCC‐85), gastric adenocarcinoma (AGS)(ATCC‐1739) cell lines used evaluate cytotoxicity bioglasses MTT assay. biological efficiency doped fluorophosphate enhancing capacity ionic dissolution products enhance osteocalcin ALP activity. phosphate‐based with possesses strength nearer bone, higher bonding ability rate biodegradation equaling than commercially available bioglass.

Silicon-Doped Titanium Dioxide Nanotubes Promoted Bone Formation on Titanium Implants

While titanium (Ti) implants have been extensively used in orthopaedic and dental applications, the intrinsic bioinertness of untreated Ti surface usually results in insufficient osseointegration irrespective of the excellent biocompatibility and mechanical properties of it. In this study, we prepared surface modified Ti substrates in which silicon (Si) was doped into the titanium dioxide (TiO₂...

Preparation and Characterization of Cerium Doped Titanium Dioxide Nanoparticles by the Electrical Discharge Method

Titanium dioxide nanoparticles (TiO2) are known as a widely used photocatalyst. In order to improve the performance of these nanoparticles, the recombination of the electron-cavity pair must be reduced and the absorption rate of the visible region should be expanded. One way to increase the performance of these nanoparticles is using cerium doped TiO2. In the present study, pure and doped titan...

Dental follicle stem cells in bone regeneration on titanium implants

BACKGROUND We aimed to demonstrate that DF stem cells from impacted molars and canines can be used to improve bone regeneration on titanium implants surfaces. This study highlights the presence of stem cells in DF, their potential to adhere and differentiate into osteoblasts on different types of titanium surfaces. RESULTS Isolated cells from the harvested DF tissue from impacted canine/molar...

A visible light driven doped TiO2 nanophotocatalyst: Preparation and characterization

A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...
