Patent number: 4666406Abstract: A light delivery device and resin curing method to facilitate access to and improved curing of composite material applied, for example, to posterior teeth cavity preparations. The light delivery or photocuring device basically comprises a fibre optic wand having a slender rod shaped or needle like fibre optic tip or end cap. Improved photocuring may be effected with the light transmitting fibre optic tip being placed and/or oscillated juxtaposition with the light curable resin deposited within a tooth cavity.Type: GrantFiled: January 13, 1984Date of Patent: May 19, 1987Inventor: John Kanca, III
