A spot curing lens (10) adapted for use with a light emitting device to spot cure a portion of a light curable adhesive, comprises a wall (16) extending between two ends (20, 22) of a lens body (14) that at least partially inhibits transmission of curing light energy through it, so that curing light energy transmitted by the spot curing lens has a pattern that is smaller than a footprint of light energy that enters the first end of the lens body. A spot curing lens adapted for use with a light emitting device to spot cure a portion of a light curable adhesive, used to adhere a translucent dental appliance to a substrate, comprises a base (12) configured to attach a light emitting device that emits a footprint of light energy; a lens body having a first end proximal to the base through which footprint of light energy emitted by a light emitting device enters, and a second end distal to the base that is smaller than the first end through which light energy exits; and a wall extending between the first and second ends of the lens body that at least partially inhibits transmission of curing light energy through it, so that curing light energy transmitted by the spot curing lens has a pattern that is smaller than the footprint of light energy that enters the first end of the lens body. Independent claims are also included for: (1) a light curing system for use in adhering a translucent dental appliance to a substrate, comprising a light emitting device that emits a footprint of light energy; a spot curing lens; and a curing mechanism for light curing a remaining portion of a light curable adhesive that has been spot cured using the spot curing lens; and (2) a method of adhering a translucent dental appliance to a substrate, comprising applying a light curable adhesive to a surface of a translucent dental appliance(s) and/or a substrate to which the translucent dental appliance is to be adhered; positioning the translucent dental appliance against the substrate surface; spot curing a portion of the light curable adhesive so that a remaining portion of the adhesive surrounding the portion that is spot cured remains uncured; removing any excess light curable adhesive that may have been expressed from between the dental appliance and the substrate surface, when positioning the dental appliance against the substrate surface; and light curing the remaining portion of the adhesive to securely bond the dental appliance to the substrate surface. |
