Embodiment approach 1

[0063] Embodiment 1 is a method of using a hardenable dental article comprising:

[0064] The hardenable dental article is provided, comprising a base, at least one inner surface extending from the base, and an inner membrane in contact with at least a portion of the at least one inner surface, wherein at least said base and said at least one inner surface comprise a hardenable dental composition, and wherein said hardenable dental composition is in the form of a self-supporting malleable structure;

[0065] applying the hardenable dental article to a dental structure;

[0066] customizing the shape of the hardenable dental article;

[0067] at least partially curing the hardenable dental article, wherein the inner membrane is in contact with at least a portion of the at least one inner surface during the curing step; and

[0068] The inner membrane is removed from the hardenable dental article.

Embodiment approach 2

[0069] Embodiment 2 is a method of using a hardenable dental article comprising:

[0070] The hardenable dental article is provided, comprising a base, at least one inner surface extending from the base, and an inner membrane in contact with at least a portion of the at least one inner surface, wherein at least said base and said at least one inner surface comprise a hardenable dental composition, and wherein said hardenable dental composition is in the form of a self-supporting malleable structure;

[0071] applying the hardenable dental article to a tooth surface in the oral cavity of a subject; customizing the shape of the hardenable dental article; and

[0072] The hardenable dental article is at least partially cured, wherein the inner membrane is in contact with at least a portion of the at least one inner surface during the curing step.

[0073] Embodiment 3 is the method of embodiment 2, further comprising removing the inner membrane after the curing step.

Abstract

This application relates to methods of using hardenable dental articles. The method can include providing a 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.

Description

technical field [0001] The present disclosure generally relates to methods of using or curing hardenable dental articles. Background technique [0002] Hardenable dental articles, including those comprising hardenable dental compositions, are widely used in restorative dentistry, which are malleable and thus customizable. For example, restoration of teeth utilizing temporary and permanent dental articles such as preformed crowns or bridges is a common procedure in which the restoration process is accelerated by using a preformed dental article in the approximate shape of the tooth or teeth being restored. When a custom-made dental product is desired, it is often required to use conventional techniques such as adhesives, pastes, two-part powder / liquid systems, preformed metal or polymer temporary crowns, and preformed ceramic or porcelain / metal permanent crowns. Multiple visits to the dentist. [0003] When the hardenable dental article cures, shrinkage can occur ranging fr...
