Abstract: The present disclosure provides engineered surfaces that exhibit reduced specular reflection and gloss while still providing a high intensity of reflected light at multiple incident angles. The structured metal surfaces include engineered topography that increases diffuse reflection, leading to a greater intensity of light perceived at multiple viewing angles. A viewer engaging such surfaces is likely to perceive a stronger ‘white’ reflection of the incident light and an improvement, particularly in orthodontic and other oral applications, of aesthetic appearance. Methods of creating the engineered surfaces and orthodontic articles incorporating the engineered surfaces are also disclosed.

Abstract: Attachments of the present disclosure combines the optimal practices of the traditional bracket-wire system and more recent resilient appliance (e.g., CTAs and polymeric bands) systems. The attachments include prescribed in/outs, torques and angulations designed utilizing the straight wire methodology for determining the bonding location on a particular tooth of the dental arch. A marriage of bracket prescription with attachment placement can help the treating professional to better visualize the treatment outcome with the tray or band on the patient.

Abstract: An orthodontic article is described comprising the reaction product of a free-radically polymerizable resin; a first free-radical photoinitiator having sufficient absorbance at a first wavelength range; and a second free-radical initiator selected from a second photoinitiator having sufficient absorbance at a second wavelength range, wherein the second wavelength range is different than the first wavelength range, or a thermal free-radical initiator. In some embodiments, the first free-radical photoinitiator exhibits a maximum absorbance at a wavelength of the range of 370-380 nm or 320-330 nm and/or comprises photoinitiator groups selected from acyl phosphine oxide or alkyl amine acetophenone. Also described are photopolymerizable compositions and methods.

Abstract: The present disclosure provides a photopolymerizable composition comprising 50-90 wt % of at least one urethane component, 5-50 wt % of at least one reactive diluent, 0.1-5 wt % of a photoinitiator, and optionally an inhibitor, wherein said composition has a viscosity at a temperature of 40 degrees Celsius of 10 Pa·s or less, as determined using a magnetic bearing rheometer using a 40 mm cone and plate measuring system at a shear rate of 0.1 l/s. The present disclosure also provides an article including the reaction product of the photopolymerizable composition, in which the article exhibits an elongation at break of 25% or greater. Further, the present disclosure provides a method of making an article including (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized urethane component and/or reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.
