Fractured implant: Remove or bury?

The implant in question is fractured, causing the abutment and crown to be dislodged. You can see the distal aspect of the occlusal platform bulges out and this implant will no longer support an abutment or screw.

We report on the first deep-ultraviolet/ultraviolet (DUV/UV) emission using a highly compact microwave-driven plasma-core photonic crystal fiber. The latter consists of a few centimeter long micro-plasma column of a gas mixture in the core of Kagome hollow-core photonic crystal fiber. The plasma is ...

A robust optical parametric amplifier (OPA) scheme is proposed in which we have experimentally achieved broadband bandwidth for a collinear OPA design that exhibits good beam quality and spatial distribution using a type-I β barium borate crystal. The applied pump pulses are simultaneously ...

Halide perovskite has attracted significant attention because of excellent optical properties. Here, we study the optical properties of CsPbBr_3 perovskite nanosheets and observe that the nonlinear optical properties can be tuned by the thickness. The photoluminescence (PL) properties and nonlinear ...

In this Letter, we explore the dispersion of spoof surface plasmons supported by a single-layer glide-symmetric structure. This structure consists of an infinitely long double-notched slot perforated in a metal layer. The presence of a degeneracy of the two lowest-order modes at the Brillouin zone ...

In this work, we theoretically and experimentally demonstrate an unusual air mode silicon nanobeam cavity design with dielectric mirrors. This design combines an extremely strong localization of light-matter interaction in the cavity center and a reduced sensitivity of the resonator wavelength to ...

It is predicted that the optical force induced by a surface plasmon can form a stable equilibrium position for a resonant particle at a finite distance from the surface. The levitated particle can be efficiently propelled along the surface without touching it. The levitation originates from the ...

We report on a semiconductor saturable absorber mirror mode-locked Nd:YVO_4 laser operating at discretely selectable 1064.0, 1073.0, 1085.1   nm wavelengths with the average output powers of more than 2.2   W at each of the three wavelengths. The optical-to-optical efficiencies and the ...

Polycrystalline 2D layered molybdenum disulfide (MoS_2) films were synthesized via a thermal decomposition method. The MoS_2/Si heterostructures were constructed in situ by synthesis MoS_2 on plane Si substrates. Such MoS_2/Si heterostructures exhibited high sensitivity to light illumination with ...
