Articles comprising first and second coextruded polymeric nettings are described. The articles comprise a plurality of pairs of first segments comprising a first material. Adjacent first segments are joined together via a second segments comprising second material, wherein the second segments extend past the first major surface of each first adjacent segments. The articles further include an adhesive on at least one of the first or second major surfaces of the first segment. The first segments, second segments, and third material each extend continuously for at least 5 mm in the machine direction, and the first and second materials of adjacent pairs are periodically bonded together in the machine direction. A portion of some of the first segments of the first coextruded polymeric netting are engaged between some of the adjacent first segments of the second coextruded polymeric netting.

A medical article and methods of using same. The medical article can include a machine direction (MD) and a cross-machine direction (CMD); a support layer; and a viscoelastic layer. The viscoelastic layer can be coupled to the support layer, and the viscoelastic layer can be discontinuous in the MD and/or the CMD. The viscoelastic layer can recover at least 70% of its deformation after 48 hours at room temperature after being strained to 50% elongation, such that the medical article has a first tensile stiffness Tat a first strain rate S, and a second tensile stiffness Tat a second strain rate S. The ratio of S/Scan be at least 100, and the ratio of T/Tcan be at least 1.5. The method can include wrapping the medical article around a body part; applying the first strain rate S; and applying the second strain rate S.

The present application is directed to a method of using a hardenable dental article. The method can include providing the hardenable dental article; applying the hardenable dental article to a dental structure; customizing the shape of the hardenable dental article; and at least partially curing the hardenable dental article.

Methods of using hardenable dental articles

A method of using hardenable dental articles. The method can include placing a film () onto a dental structure () to cover at least a portion of the dental structure (); providing a hardenable dental article (); and applying the hardenable dental article () to the dental structure () covered by the film ().

A securement device for securing a medical article is disclosed. The securement device comprises a base and a first securing portion comprising a strap that is movable between an open position and a closed position and a connector disposed on the base. The strap cooperates with the connector in the closed position to form an enclosure. The strap further comprises a curvilinear segment that projects inwardly into the enclosure in a convex orientation when the strap is in the closed position. Securement systems for securing medical articles and methods of securing at least a portion of a medical article to a patient are also provided.

A digital painting process provides computer-controlled finishing of dental articles. The process can selectively apply different materials over portions of a dental article in one or more layers to achieve a multi-chromatic finish having a variety of colors, finishes, and surface properties that closely match the appearance and function of human dentition.

Digitally-painted dental articles

By capturing a highly detailed three-dimensional digital model of dentition, a suitable replacement dental article be fabricated with a combination of digitally-controlled reductive processes such as milling and digitally-controlled additive processes such as digital painting. A dental article so-manufactured can provide an aesthetically pleasing, multi-chromatic appearance that closely matches surrounding dentition.

A hardenable dental article including a base and at least one outer surface extending from the base, wherein at least the base and the at least one outer surface of the hardenable dental article includes a hardenable dental material; and a multi-layer polymeric film conformable release liner in contact with at least a portion of the at least one outer surface.

Preformed malleable dental articles and methods

A method of making a biometric dental appliance. A first article can be formed of a first material based on a first digital surface representation having a desired outer shape of the dental appliance. A portion of the first article can then be removed to form an outer layer of the dental appliance comprising a cavity dimensioned to accommodate an inner layer. A second article can be formed by filling the cavity of the first article with a second material. The second material can have at least one different structural and/or optical property than the first material. The second article can be further processed, as desired. For example, a desired inner shape can be formed in the second article. Such a desired inner shape can be based on a second digital surface representation of a dental object configured to receive the dental appliance.
