INTRODUCTION Cartilage interposition grafting is commonly utilized during allograft ossiculoplasty as a way to prevent extrusion of the prosthesis through the tympanic membrane. Even with the earliest materials such as Plastipore (Xomed, Jacksonville, FL) and hydroxyapatite, use of cartilage interposition has led to lower extrusion rates without the expense of poorer hearing outcomes. Allograft...

To investigate and verify the degree to which forming properties of low plasticity materials are improved at room temperature using granular medium (GMF) process 500 °C, a coupled Eulerian–Lagrangian unit calculation model was established special mold designed conduct GMF experiment for titanium alloy sheets under different-shaped pressing blocks. Then, three-coordinate measuring machine, sizes...

In this study, the cold rolling microstructure and static recrystallization mechanism of high strength titanium alloy Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe were systematically investigated. Results show that is mainly composed elongated deformed ? grains containing micro-shear bands. After annealing at 815 °C for 2 min, fine SRXed are observed, concentrated in band, grain boundary interior grain. The s...

Although fluoride induces corrosion in titanium in an oral environment, the influence of protein on this corrosion remains to be clarified. The objective of this study was to investigate suppression of fluoride-induced corrosion of titanium where albumin was either present in a solution or where albumin was preadsorbed on titanium. Titanium dissolution in titanium specimens and surface characte...

There are very few reports on hypersensitivity reactions in association with titanium-based materials so that the existence of allergy to titanium is still put in question. We report on a patient in whom impaired fracture healing and eczema localized to the perioperative area developed upon titanium-based osteosynthesis. Patch testing gave no reactions to titanium nor to nickel, chromium, or co...

Titanium (Ti) mesh plates are used as a bone replacement in brain tumor surgeries. In the case of radiotherapy, these plates might interfere with the beam path. The purpose of this study is to evaluate the effect of titanium mesh on the dose distribution of electron fields. Simulations were performed using Monte Carlo BEAMnrc and DOSXYZnrc codes for 6 and 10 MeV electron beams. In Monte Carlo s...
