Abstract
The present invention provides assemblies, kits, and methods including a compressible material. Optionally, a hardenable dental composition (e.g., an adhesive or primer) is in contact with the compressible material for bonding a dental article (e.g., an orthodontic appliance) to a tooth structure. Removal of excess hardenable and/or hardened dental composition, if desired, can be facilitated for embodiments in which the hardenable dental composition is an unfilled or a lightly filled composition.
Claims26
A dental assembly for indirect bonding of one or more dental article to a tooth structure, the dental assembly comprising:
- a placement shell configured to removably receive one or more dental article;
- and
- one or more dental article bonded to the placement shell, each of the one or more dental article comprising:
- an outer surface,
- a compressible material disposed on the outer surface,
- the compressible material capable of being reduced in volume upon application of pressure and at least partly configured to form a bond with the tooth structure, and
- a hardenable dental composition at least partially within the compressible material that, during use, is configured to form a bond with a tooth structure.
A method for preparing a dental assembly, the method comprising:
- providing a placement shell configured to removably receive a one or more dental article;
- providing one or more dental article for bonding to a tooth structures, each of the one or more dental article comprising:
- an outer surface,
- a compressible material disposed on the outer surface of each dental article,
- the compressible material is-capable of being reduced in volume upon application of pressure and at least partly configured to form a bond with the tooth structure, and
- a hardenable dental composition at least partially within the compressible material that, during use, is configured to form a bond with a tooth structure;
- and
- securing each of the one or more dental articles onto the placement shell.
