发明名称 Bondable dental assemblies and methods including a compressible material
摘要 Dental assemblies and related methods of making are provided. The dental assemblies include a dental article with a bonding surface an adhesive having both a compressible material and at least one hardenable dental composition extending across the bonding surface. The compressible material is coupled to the dental article by a first quantity of hardened dental composition extending at least partially through the compressible material and contacting the bonding surface. The hardened dental composition extends over less than the entire bonding surface. Adjacent portions of the compressible material contain a second quantity of unhardened dental composition, preserving flexibility of the compressible material. Advantageously, this configuration was found to enhance bond reliability and facilitate manufacturing.

主权项 1. A method of making a dental assembly comprising: placing a compressible material in contact with an outer base surface of a dental article; applying a first quantity of an unhardened dental composition to at least one of the compressible material and the outer base surface in such a manner that at least some of the unhardened dental composition is located between the outer base surface and the compressible material; compressing at least a portion of the compressible material to urge the compressible material toward a configuration complemental to the outer base surface; hardening at least a portion of the first quantity of dental composition in order to secure the compressible material to the outer base surface while the compressible material is at least partially compressed, wherein at least part of the outer base surface is not in contact with the hardened dental composition; and applying a second quantity of unhardened dental composition to the compressible material, wherein the second quantity at least partially surrounds the hardened portion of the first quantity as viewed from a direction perpendicular to the outer base surface and is in contact with a portion of the outer base surface not in contact with the hardened dental composition.
