  • Patent number: 5759032
    Abstract: A dental curing accessory that fits on the light emitting tip of a curing light and is pressed against a photocurable material and its immediate underlying structure such as a tooth, appliance, or dental structure while the photocurable material is polymerizing. The present invention is a partially hollow tubular body having a receiving portion which fits onto the curing light tip, and also has a light permitting contact portion which contacts the photocurable material transferring pressure from the device to the photocuring site. Pressure delivered to the photocuring site through the present invention promotes intimate contact between a photocurable material and a structure to which the photocurable material is bonded or attached to, providing a stronger bond, reducing voids in the photocurable material, contouring the photocurable material against the structure resulting in a more even surfaced product requiring less finishing work, and substantially preventing the formation of an oxygen inhibited layer.
