摘要： A dental resin composition that includes a dental resin. The composition includes metal-modified cerium oxide nanoparticles (mCNPs) having a predominantly 3+ cerium surface charge and in a range of about 3-25 nm in size and mixed in an amount that is in a range of about 0.01 to 0.1 weight percentage of a mixture having the dental resin and the mCNPs. The m is an antimicrobial promoting metal that is non-ionizing. The mCNPs effectuate release directed hydrogen peroxide (H2O2) in an oral cavity that is then used against bacteria in the oral cavity to prevent local acidification of a tooth on which a therapeutically effect amount of the mixture is applied and cured. The dental resin composition includes one of an acrylic-based polymer resin, a methyl methacrylate-based resin, photopolimerisable resin composite, and urethane dimethacrylate-based dental resin.

摘要： The specification discloses a dental curing light including 1) a light engine, 2) a coaxially aligned, camera-based viewing system, and 3) a control system providing a variety of safety features and simplified, operator-friendly operation. The camera’s field of view (FOV) is coaxial with the centerline of the curing beam of the light engine. The curing light includes a multi-planar dichroic mirror (MDM) providing viewing and light beam direction aligned with the target. The MDM provide multiple images to the camera from different angles. The camera provides real-time measurement of light intensity reflected back from the targeted surface. Using the multiple image portions reflected by the multi-planar dichroic mirror, the control system computes the distance between the curing light and the target. The reflected intensity and the calculated distance enable the control system to compute a light engine irradiance to achieve a desired irradiance at the targeted surface.

摘要： An implant and abutment tooth assembly includes an implant, a rotatable connector, a screw bolt, and a photocurable resin capsule. The implant includes a threaded section and a rotatable adjustment seat, wherein the rotatable adjustment seat has an upper connection portion. The upper connection portion has a groove, two spherical portions, and a receiving trench. The rotatable connector includes a spherical rotation face, two end faces, an abutment, an internal screwing section, and a stepped notch. The screw bolt includes an external screwing section, a rotary head, and a force segment. The external screwing section is screwed with the internal screwing section of the rotatable connector, and the rotary head is movably received in the stepped notch of the rotatable connector. The photocurable resin capsule includes 0.1 g to 0.8 g of light-cured resin and is accommodated in the receiving trench of the implant.

摘要： A curing light (300) may emit light in one or more directions through either a two-dimensional or a three-dimensional head (301). When using a head (301) with three facets (304), (305), (306) each facet has a light source (309a), (309b), (309c) and a detector (308), which may or may not be integrated into a unit. Light sources (309a), (309b), (309c) may be activated in different sequences to cure composite within a structure, such as a tooth, with controls of light emitting in each facet. Light sources (309a), (309b), (309c) may also be controlled by utilizing feedback from detector (309) or other sensors. Detectors (308) may detect position, power, heat, or any other useful characteristic.

摘要： This invention relates to a tooth repair system including a method of: drilling an aperture in, e.g., a broken anterior tooth to a predetermined depth; providing a fiber optic—preferably of a diameter of between 0.3 and 1 millimeter and elastic modulus of between 22 GPa and 83 GPa—with a length longer than the predetermined depth; placing and adhering the fiber optic within the first aperture so that a portion of the fiber optic is exposed beyond the broken tooth surface; and restoring the broken tooth surface around the exposed fiber optic so that the fiber optic anchors a restored tooth portion to the broken tooth surface. The system also provides a tooth repair pin with the above characteristics, being acid-etched and silane coated with a carrier sleeve.

摘要： A dental light polymerization device has an intra-oral tip portion and a handle portion. The dental light polymerization device has a polymerization light source and a light mixing element. The polymerization light source has a first LED exhibiting a first light emission peak wavelength and a second LED exhibiting a second light emission peak wavelength. The first and second LED each are configured for emitting visible light within a wavelength range of 380 nm to 495 nm. The first and second light emission peak wavelength differ from each other by at least 10 nm. The light mixing element is formed of a solid transparent body that has a rear portion and an adjacent front portion. The rear portion has the shape of a square-based truncated pyramid. Further, the front portion has a convex shape. The rear portion forms a rear end of the light mixing element and the front portion forms a front end of the light mixing element. The rear end forms a first diagonal dimension and the rear portion, adjacent the front portion, forms a greater second diagonal dimension. The light mixing element is arranged with the rear end facing the polymerization light source and with the front end facing away from the polymerization light source.
