The aim of this study was to compare the static and kinetic frictional forces generated by various contemporary designs of self-ligating brackets (SLBs) and different wire alloys. In total, six different brackets (four passive type SLB, one active SLB, and one conventional bracket) were investigated using stainless steel, nickel-titanium, and titanium-molybdenum alloy archwires of several sizes...

In laparoscopic surgery for colorectal and gastric cancer, it is difficult to locate the tumor in cavity excision. Tumors colon or stomach are blocked by mucous membranes; thus, view from obscured. Therefore, determine location of tumor, a marker can be installed around found using sensor. Until now, most clip-detectors that have been developed detect tumors either cancer. The research on devel...

We introduce the first example of isoreticular titanium–organic frameworks, MUV-10 and MUV-12, to show how different affinity hard Ti(IV) soft Ca(II) metal sites can be used direct selective grafting amines. This enables combination Lewis acid titanium centers available -NH2 in two sizeable pores for cooperative cycloaddition CO2 epoxides at room temperature atmospheric pressure. The molecules ...

The creep response in the air of commercially pure titanium was investigated at 550, 600, and 650 °C to assess effect oxidation on mechanical response. Experiments demonstrated that prolonged exposures high temperatures produced a marked reduction minimum rate under given applied stress. Microhardness measurements showed hardened zone formed proximity surface due oxygen penetration into metal. ...

Although percutaneous titanium implants have become one of the best choices as retainers in the facial defects, peri-implantitis still occurs at a significant rate. This unwanted complication occurs due to adhesion of bacteria and subsequent biofilm formation. To solve this problem, we have developed a novel antibiotic nanodelivery system based on self-decomposable silica nanoparticles. In this...

The aim of this preliminary prospective RCT was to histologically evaluate peri-implant soft tissues around titanium abutments treated using different cleaning methods. Sixteen patients were randomized into three groups: laboratory customized abutments underwent Plasma of Argon treatment (Plasma Group), laboratory customized abutments underwent cleaning by steam (Steam Group), and abutments wer...
