STATEMENT OF PROBLEM Zirconia implants have been used for oral rehabilitation; however, evidence of their ability to maintain crestal bone and periimplant soft tissue health is not clear. PURPOSE The purpose of this systematic review was to evaluate crestal bone loss (CBL) around zirconia dental implants and clinical periimplant inflammatory parameters. MATERIAL AND METHODS The focus questi...

We demonstrate the generation of an intense soft-x-ray-laser beam by saturated amplification of high harmonic seed pulses in a dense transient collisional soft-x-ray-laser plasma amplifier created by heating a titanium target. Amplification in the 32.6 nm line of Ne-like Ti generates laser pulses of subpicosecond duration that are measured to approach full spatial coherence. The peak spectral b...

PURPOSE The aim of this study was to evaluate the treatment outcome of implants placed in the maxillary anterior segment. MATERIALS AND METHODS Patients were treated with bone-level implants (Straumann Bone Level Implant, Institut Straumann) that supported all-ceramic single crowns and were followed for 2 to 4 years. Titanium or ceramic abutments were used according to the quality of the soft...

Many dental implants fail due to the infection and inflammation that walk hand in hand with poor healing and soft tissue integration. Titanium surfaces were nanocoated with quercitrin, a natural flavonoid, with the aim to improve soft tissue integration and increase dental implants success. Streptococcus mutans attachment and biofilm formation was analysed. Then, the anti-inflammatory propertie...

the aim of this animal study was to evaluate the possible effects of carbonated soft drink consumption on the rate of orthodontic tooth movement in rats.thirty-six adult male sprague-dawley rats were randomly divided into two experimental groups and one control group. in the experimental groups (a&b;), the water in the dietary regimen was replaced with soft drinks (fanta® in group a and cola® i...

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...
