purpose: to compare the complications of pegging between the polycarbonate peg system and the titanium peg system. method: complications associated with pegging (polycarbonate: bio-eye or titanium: dr-perry new p-k) were reviewed from the hospital records of 153 patients over 5 years. results: out of 153 cases, 96 (62.3%) were male and 57 (37.7%) were female. mean age was 27.7 yr (6-59 yr). in ...

Using a laser velocity interferometer, wave profiles were recorded in porous (porosity 30%) nickel aluminide samples. Data on shock compressibility obtained. An abnormally high compaction was found, manifested the intersection of Hugoniots solid and samples at pressure 28 GPa, which indicates phase transition. Keywords: waves, Hugoniot, transitions, Doppler interferometers, intermetallides.

Titanium is an ideal material for use in prosthodontics because of its biocompatibility, corrosion resistance, and mechanical strength combined with its lightweight. Recently the use of titanium and titanium alloys for fixed restorations has increased substantially, mainly due to the improvement of techniques for the casting titanium and its alloys. This article reviewed the studies on titanium...

objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface.  materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...

Additive manufacturing technologies, particularly electron beam powder bed fusion (PBF-EB/M), are becoming increasingly important for the processing of intermetallic titanium aluminides. This study presents effects hot isostatic pressing (HIP) and subsequent two-step heat treatments on microstructure mechanical properties TNM-B1 alloy (Ti–43.5Al–4Nb–1Mo–0.1B) fabricated via PBF-EB/M. Adequate s...
