The aim of this study was to quantify the extent of abutment screw loosening and thus understand the role of frictional and wear factors in abutment screw loosening by using a cyclic loading device to compare Diamond Like Carbon (DLC)-coated and non-coated implants. The properties of DLC films, including hardness, wear resistance, chemical stability, and biocompatibility, are similar to those o...

Bimetallic dichlorotitanium complexes, {2,6-[eta(5)-2,5-Me2C5H2](2)-4-R-C6H2N-microN}{Ti(IV)Cl2}2 (, R=Me; , R=F) and 4,4'-A[{2-(eta(5)-2,3,5-Me3C5H)C6H3NC6H11-kappaN}Ti(IV)Cl2]2 (, A=CH2; , A=O; , A=ortho-C6H4) are prepared via a key step of the Suzuki-coupling reaction of 2-dihydroxyboryl-3-methyl-2-cyclopenten-1-one () with dibromo-compounds. The solid state structure of was determined by X-...

Crucial model synthetic and mechanistic studies directed toward the development of methodology for the construction of the maleic anhydride moiety of the CP-molecules are described. Studies directed toward the stereoselective attachment of the upper side chain, culminating in the discovery of long-range stereochemical control, are also discussed. In addition, a first-generation strategy toward ...

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 ...

Ti-6Al-4 V alloy when processed by laser powder bed fusion (LPBF) is a useful material which can be used for the manufacture of complex 3D components aerospace and medical applications. LPBF fabricated typically shows high tensile strength (>1200 MPa) but poor ductility (<10%), explained characteristic microstructures that form under cooling rates multiple thermal cycles. Here, composition feed...

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...

Journal of Medical Sciences 2011;14(2):68-70 expression for CD99 (MIC2), with characteristic membranous pattern and an IMPRESSION drawn was Conformation of diagnosis of EWINGS SARCOMA. Bone Scan was also advised which revealed Reduced uptake over the body of left mandible without rim of enhanced uptake. No evidence of distal bone involvement. A surgical procedure was performed to resect the mal...

The electrochemical behavior of polycrystalline TiO₂ anatase coatings prepared by a one-step hydrothermal synthesis on commercially pure (CP) Ti grade 2 and a Ti13Nb13Zr alloy for bone implants was investigated in Hank's solution at 37.5 °C. The aim was to verify to what extent the in-situ-grown anatase improved the behavior of the substrate in comparison to the bare substrates. Tafel-plot extr...
