摘要:
Hardenable and hardened dental compositions that include thermally responsive additives, and articles including such hardenable and hardened compositions, are provided. Upon heating, the hardened compositions are useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.

Hardenable and hardened dental compositions that include radiation-to-heat converters, and articles including such hardenable and hardened compositions, are provided. Upon irradiating, the hardened compositions increase in temperature, which can be useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.

摘要:
Processes for forming dental materials that include applying a first hardenable dental composition (e.g., a dental adhesive) to a surface followed by applying a second hardenable dental composition (e.g., a dental composite) to the first hardenable dental composition on the surface. The first and second hardenable dental compositions are hardened such that the second hardenable composition is substantially completely hardened prior to complete hardening of the first hardenable composition.
摘要:
The present invention features ionomer compositions containing nanofillers. The compositions can be used in a variety of dental and orthodontic applications, for example, as adhesives, cements, restoratives, coatings and sealants.

摘要:
A free-radical initiator system that includes a combination of an oxidase enzyme, a peroxidase coenzyme, an oxidase substrate, and a reductant (i.e., reducing agent). This system can be used with a resin system that includes a polymerizable component.

Thermally responsive compositions that include a thermally responsive viscosity modifier, a polymerizable component, and water are provided. The compositions, which optionally may be hardened, are useful for application to a surface of a body.
摘要:
The invention features a photopolymerizable composition that comprises a cationically polymerizable resin, and a photoinitiator system comprising an iodonium salt, a visible light sensitizer, and one or more anthracene-based compounds as electron donors. Electron donor combinations used in the invention include multiple substituted anthracene compounds or a combination of at least one substituted anthracene compound with unsubstituted anthracene.
