Materials with differing surfaces have been developed for clinical implant therapy in dentistry and orthopedics. This study was designed to evaluate bone response to titanium alloy containing Ti-32Nb-5Zr with nanostructure, anodic oxidation, heat treatment, and ibandronate coating. Rats were randomly assigned to two groups for implantation of titanium alloy (untreated) as the control group and ...

Titanium and its alloys are typically used for fabrication of dental and orthopedic implants as they posses various desirable properties including biocompatibility and corrosion resistance. In spite of such benefits, titanium implants show lack of osseointegration after surgery in minor cases. The objective of this research has been to modify the surface of titanium alloy for medical applicatio...

The objective of this present study was to create a biosensor which can monitor in situ orthopedic tissue growth juxtaposed to a newly implanted orthopedic material. This biosensor has unique properties including the ability to sense, detect, and control bone regrowth. Such a biosensor is useful to not only regenerate tissue necessary for orthopedic implant success but it also aids in informing...

PURPOSE This study was to investigate the effects of recombinant human platelet-derived growth factor (rhPDGF-BB) and heparin to titanium surfaces for enhancement of osteoblastic functions and inhibition of inflammation activity. MATERIALS AND METHODS The anodized titanium discs, not coated with any material, were used as a control group. In heparinized- Ti group, dopamine was anchored to the...

There is limited dental literature evaluating the retentive capabilities of luting agents when used between metal components, such as cast metal restorations cemented onto machined metal implant abutments. This study compared the retentive strengths of 5 different classes of luting agents used to cement cast noble metal alloy crowns to 8-degree machined titanium cementable implant abutments fro...

This paper presents titanium dioxide nanostructured surfaces prepared in organic electrolytes containing ammonium fluoride by anodic oxidation method. Two approaches were used for fabrication, one-step and two-step anodization. The obtained TiO2 surfaces have nanoporous structure. The morphology of anodized TiO2 nanostructures was characterized by scanning electron microscopy (SEM).

PURPOSE The purpose of this study was to evaluate bone response to anodized titanium implants coated with the extract of black cohosh, Asarum Sieboldii, and pharbitis semen. MATERIALS AND METHODS FORTY ANODIZED TITANIUM IMPLANTS WERE PREPARED AS FOLLOWS: group 1 was for control; group 2 were implants soaked in a solution containing triterpenoids extracted from black cohosh for 24 hours; group...

BACKGROUND AND OBJECTIVES Although the laser is one of the widely used systems in dental field, literature about the biological effects of laser irradiation on the titanium surface is rare. The aim of this study was to investigate the responses of osteoblast-like cells seeded onto laser irradiated anodized titanium discs, using a CO(2) (carbon dioxide) and Er,Cr:YSGG (erbium chromium-doped yttr...
