A dental impression material includes: a base material paste that includes an alginate and water; and a curing material paste that includes a gelling reagent and a poorly water-soluble liquid compound. A viscosity of 10% aqueous solution of the alginate at 20? C. is 5 mPa.Math.s or more and 90 mPa.Math.s or less.

A dental article such as a dental tray aligner or a dental crown that includes a substrate including a polymeric material having a modulus of elasticity that reduces upon exposure to water and a water-resistant coating on the substrate, where the water-resistant coating comprises parylene. In some examples, the water-resistant coating may include one or more layers that include parylene.

The present disclosure provides a range of printed materials comprising discrete layers or segment with distinct compositions, and which can collectively lend to high levels of strength, toughness, and break resistance, and these printed materials may contain thin, ductile layers interspersed between thicker, harder layers, thus in printing such materials, the present disclosure further provides a range of compositions and methods, including low viscosity, air stable, and rapidly solutions amenable to thin layer inkjet printing.

The invention is an assortment of apparatuses to magnetically tether a dental hygienist's hand to the utility tubes and hoses commonly found in a dental office. In a preferred embodiment, this is a ring containing a magnet which is worn by the hygienist. This tethers him or her finger to a utility hose or tube, which has a clasp that contains a reciprocal magnet. In another embodiment, the invention is a finger hold which contains a magnet that tether to the utility hose or tube via the magnetized clasp.

Disclosed herein is a method for forming an anti-microbial layer on an apparatus. Also disclosed is a method for improving the anti-bacterial properties of a titanium device coated with titanium-nitride (TiN). Also disclosed is a medical apparatus comprising an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

An orthodontic abutment that includes a base suitable for fixing the orthodontic abutment to an implant, a cap fixed to the base and a set of retention elements arranged along a side wall of the cap. The set of retention elements is suitable for receiving orthodontic elements and includes: a bracket with wings, a hook arranged under one of the wings of the bracket, a projection arranged on the cap oppositely to the bracket, a hollow tube formed inside the projection, a curved rod hook arranged on the projection below the hollow tube, and a button with an eyelet arranged above the hollow tube.

A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mm.sup.3 and an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm.sup.3.

A surgical guide system for the placement of dental implants includes a guide base attachable to the maxillary or mandibular bone, an aligner attachable to the base and to be positioned in the space relative to the reference tooth, teeth, or other anatomical landmarks remaining in the mouth, and a drilling guide attachable to the guide base and including at least one drill guide hole for guiding a drill. wherein the guide base: is substantially rigid; is resting mostly on the mucosa; is essentially matching the shape of a maxilla or a mandible and present a central part placed on the interior surface of the jaw, intended to provide lingual or palatal support, and is widely perforated along the maxillary or mandibular ridge, in order to allow past any teeth still present at the start of the operation or implants to be installed during the operation.

Provided herein is an orthodontic aligning appliance for moving tooth or teeth of a patient and methods of making and using the same.
