Abstract
Official abstract text for this publication.
An orthodontic article is provided for bonding to a tooth structure comprising an orthodontic appliance, a layer of partially hardened hardenable composition adjacent the appliance, and a bonding adhesive adjacent the partially hardened hardenable composition. A method of making an orthodontic article for orthodontic bonding is provided, comprising partially hardening a hardenable composition adjacent the base of an orthodontic appliance.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of bonding an orthodontic article to a tooth structure comprising: a) applying a hardenable composition to the base of an orthodontic appliance whereby the hardenable composition extends across the base; b) partially hardening the hardenable composition to provide a partially hardened hardenable composition, the partially hardened hardenable composition being less than 95 percent cured and having a contour of a negative replica of at least a portion of the tooth structure; c) applying a bonding adhesive to the partially hardened hardenable composition whereby the bonding adhesive extends across the partially hardened hardenable composition; and d) advancing the orthodontic appliance with the partially hardened hardenable composition toward the tooth structure. 2. The method of claim 1 wherein the base has a contour of a negative replica of at least a portion of the tooth structure. 3. The method of claim 1 wherein the step of partially hardening the hardenable composition comprises directing actinic radiation to the hardenable composition. 4. The method of claim 1 wherein the step of advancing comprises holding the appliance with a transfer apparatus.
