Abstract:
1. A system for forming and coupling an attachment device onto one or more teeth, comprising: a template comprising a shell having a cavity defining a shape for receiving one or more teeth, the template including a template inner surface and a template outer surface opposite the template inner surface, the template further comprising an aperture at one or more predetermined locations that extends from the template inner surface to the template outer surface therethrough, the aperture defining an aperture perimeter; one or more attachment molds, each attachment mold comprising a mold first surface and a mold second surface opposite the mold first surface, the attachment mold includes a mold bore having a bore surface extending from the mold first surface to the mold second surface therethrough, the attachment mold further includes a mold perimeter surface that defines a predetermined shape, wherein each of the aperture perimeters being operable to receive and cooperate with the mold perimeter surface of one of the attachment molds; an adhesive layer disposed on the mold first surface for removably coupling the attachment mold to a tooth surface with the mold bore defining a portion of the tooth surface as target tooth surface; curable material disposed within and filling the mold bore from the mold first surface and the target tooth surface to the mold second surface that will be the attachment device, wherein each mold bore provides a mold for forming an attachment device of a desired shape and orientation from the curable material, the adhesive layer being enabled to provide a sealing engagement with the tooth surface that substantially prevents the curable material from migrating away from the target tooth surface between the mold first surface and the tooth surface; and a cover plate including a plate inner surface and a plate outer surface opposite the plate inner surface, the cover plate being operable to be placed upon the mold second surface and cover the mold bore, the cover plate being operable for the compression of curable material that may be within the mold bore to affect intimate contact between the curable material and the target tooth surface and minimize voids within the curable material, the cover plate comprising a material that is translucent to those light frequencies associated with curable material which is curable by exposure to light-curing radiation.
