Patent attributes
An optic tip for use with a dental curing lamp has a convex lens extending across the bottom of the mounting cup. The curing tip is a half-obloid that creates a secondary void with a compound curve in the cured filling material. The secondary void provides greater bonding area for the secondary filling material and the secondary filling material creates a contact point with the adjacent tooth. In a particular embodiment, the optic tip extends not more than 6 mm from the end of the curing wand, facilitating operation in the patient's mouth compared to larger devices. The depth of the secondary void is also self-limiting by the desirably short curing tip, allowing the dentist to cure the primary filling material without having to watch the depth of the curing tip.
