Abstract: Orthodontic adhesives are claimed which use polymeric filler particles with defined particle size characteristics. The particle size characteristics are controlled such that these adhesives provide comparable mechanical retention and cohesive strength of conventional orthodontic adhesives when used to bond orthodontic appliances to teeth.

Embodiments of the invention include both self-curing and two-part adhesives, packaged adhesive-coated orthodontic appliances, and methods for removing a cured adhesive from a tooth surface.

Abstract: Release agents with increased affinity toward nano-imprint lithography template surfaces interact strongly with the template during separation of the template from the solidified resist in a nano-imprint lithography process. The strong interaction between the surfactant and the template surface reduces the amount of surfactant pulled off the template surface during separation of a patterned layer from the template in an imprint lithography cycle. Maintaining more surfactant associated with the surface of the template after the separation of the patterned layer from the template may reduce the amount of surfactant needed in a liquid resist to achieve suitable release of the solidified resist from the template during an imprint lithography process. Strong association of the release agent with the surface of the template facilitates the formation of ultra-thin residual layers and dense fine features in nano-imprint lithography.
