1. A method for placing, compacting and shaping a light activated dental restorative material in a cavity preparation, between adjacent teeth or against a pulpal wall and for polymerizing said material in said cavity preparation, between said teeth or against said wall to produce a restoration, comprising the steps:

  • a. providing a disposable, polished, rigid, fiber optic handle member having an exposed matted working end of reduced diameter and an opposite butt end for receiving light,b. heating the working end of the handle member and shaping the tip and sides of said working end to a desired configuration approximating that of a surface or surfaces of the cavity preparation, tooth or pulpal wall to be restored,c. while holding the said handle member, using said working end to place, compact, and shape a light-activated dental restorative material in a cavity preparation or between adjacent teeth,d. while the working end is held against the shaped and compacted restorative material to maintain the desired shape of the restoration, approximating a source of curing light to the butt end of the said handle member and activating the light source, whereby curing light is transmitted substantially undiffracted through the length of said polished handle member and diffuses out from the tip and all sides of said matted working end to impinge upon said restorative material until the latter is polymerized.
