Limited shelf life due to pigment settling and the formation of hard packs in pigmented UV curable nail gels is solved by the present invention which describes a composition, method, and use of a UV curable, thixotropic, radiation curable, low viscosity gel comprised of a formulation containing thixotropic additive(s) and in some cases dispersants for additional dispersion stability. The thixotropic pigmented gel has prolonged shelf life and long time storage at ambient conditions. It also contains negligible amounts of unreactive solvent. The thixotropic additive also changes the rheological properties of the gel, which allows the nail gel to be easily applied to nails at a lower viscosity due to shear thinning.


A method for creating a substantially accurate dental restoration from scanning a negative dental impression of a patients teeth or a positive dental stone model of the patients teeth includes applying a compensation rate to compensate for the shrunk or enlarged scan of the patients teeth, to the scan of the patients teeth using the scanner to create a true dimension working file; the scan of the patients teeth using a computer system to create a true dimension working file; or a shrunk restoration file of the restoration using a restoration fabricator. A restoration can be designed based on the scan of the patients teeth and creating a restoration file. The restoration can be fabricated using a restoration fabricator.


A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including increasing amounts of yttria through a thickness of the green body. The green body is substantially white with a substantially consistent optical characteristic of chroma across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of decreasing chroma through a thickness of the dental prosthesis.

A dose-reducing x-ray aiming device includes an aiming ring having shield with an aperture, at least one arm, and at least one sensor holder. The dose-reducing x-ray aiming ring is generally used to aim a dental x-ray machine and at least partially shield some of the x-rays emitted from the x-ray machine while capturing radiographs. X-rays generally pass through the aperture and then interact with a sensor for capturing the radiographs after passing through the tissue of a patient. In one embodiment, the x-ray aiming device provides an all-in-one aiming ring, which allows a user to capture both periapical and bitewing radiographs with a single device. The aiming device also includes an annular ridge or lip which helps align the x-ray machine with the aiming device.

A medical imaging device mountable on a support structure having a horizontal surface and at least one substantially vertical surface. The imaging device includes a frame and a gantry having a radiation source and a radiation detector. The gantry is rotatable with respect to the frame. The imaging device includes a first vertical adjustment element and a second vertical adjustment element. The first vertical adjustment element has a first end couplable to the horizontal surface and a second end coupled to the frame, the first end is located a first distance from the second end, and adjustable over a first range. The second vertical adjustment element has a third end coupled to the frame and a fourth end coupled to the gantry. The third end is located a second distance from the fourth end, and is adjustable over a second range, and the fourth end is rotatable with respect to the third end.
