Aim: There is little information considering the framework association between cast clasps and attachments. The aim of this study was to evaluate the retention strength of frameworks match circumferential clasps and extra resilient attachment cast in three different alloys (cobalt-chromium, nickel-chromium titanium and commercially pure titanium), using two undercut (0.25 and 0.75 mm) and consi...

Titanium has been one of the traditional metals used in medical industry since 1940. This work modeled and simulated a hip-joint replacement implant using Creo 5.0 DEFORM 3D (v11.0), respectively. Four titanium-based billets were modeled; out four billets, three coated with specified thickness, was uncoated. Among billet 500-micron two 1000-micron thickness. At end simulation, coating materials...

The most recent advancements in food science and technology include cold sterilization of fresh-keeping packaging. Active packaging has received much interest due to the photocatalytic activity (PCA) functional nanoparticles, including titanium dioxide (TiO2) ferric oxide (Fe2O3). However, there are still significant concerns about toxicity safety these nanoparticles. This review emphasizes bac...

The present study reveals for the first time dry sliding wear behavior of a powder metallurgical pure titanium alloy (Cp-Ti) modified by shot peening. Cp-Ti samples were manufactured via metallurgy, and then their surface subsurface features using custom-made, fully automated shot-peening system. texture isotropy rate highest orientation angle shot-peened 71.5% 36°, respectively. Abbott curves ...

Investigation of the effectiveness of surface treatments that promote a strong bond strength of resin cements to metals can contribute significantly to the longevity of metal-ceramic restorations. This study evaluated the effect of surface treatments on the shear bond strength (SBS) of a resin cement to commercially pure titanium (CP Ti). Ninety cast CP Ti discs were divided into 3 groups (n=30...

AIM To evaluate the mechanical properties (ultimate tensile strength, elongation and hardness) of the commercially pure titanium (cp Ti) as casting and after ceramic firing cycles. MATERIALS AND METHODS Dumbbell-shaped specimens were prepared for the tensile strength testing. Disk-shaped cast specimens were used for microhardness testing. The ceramic firing cycles were made simulating a low f...
