摘要:
The current invention provides a photopolymerized pressure-sensitive adhesive which adheres well to all common surfaces and has an outstanding ability to bond to plasticized vinyl substrates and to remain firmly bonded thereto even after remaining in contact therewith for extended periods of time comprising an acrylic copolymer and a nitrile butadiene rubber or mixture of rubbers. Preferred pressure-sensitive adhesives of the invention comprise from about 1 to about 10 parts of the nitrile rubber or a mixture thereof.
摘要:
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.
摘要:
A method of making a multilayer all-ceramic 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 be removed to form an outer layer 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 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. At least one of the first article, the outer layer, and the second article can be fired, for example, while still being coupled to a support.
摘要:
Substituted saccharide compounds, dental compositions comprising substituted saccharide compounds, and methods of using dental compositions are described. In one embodiment, the substituted saccharide amide compound comprises a hydrophobic group and at least one free-radically polymerizable group with the proviso that the hydrophobic group is not bonded to the ethylenically unsaturated carbon atom of the free-radically polymerizable group. The hydrophobic group is typically bonded to a nitrogen atom of a saccharide amine residue or a carbonyl moiety of saccharide amide residue.
摘要:
A method of making a multi-chromatic 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 optical property than the first material. The second article can be further processed, as desired. For example, a desired inner shape of the dental appliance 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.
摘要:
Dental compositions and biphenyl di(meth)acrylate monomers are described. The dental compositions comprise at least one biphenyl di(meth)acrylate monomer comprising two aromatic rings connected with a C—C bond wherein the rings each comprise a substituent comprising a urethane moiety and a (meth)acrylate end group.
