The document introduces an optional tool guide dental labs can use to fabricate multiple shades of esthetic shade guides using acrylic resins and self-curing acrylic. The guide includes pre-fabricated molds to make individual guides incorporating three teeth from the left side, as well as tips for using metal molds, colorants, and micro-wave curing acrylic to fabricate customizable guides quickly and eliminate much of the time it would take to fabricate one at a time. The customizable guides allow dental labs to convey natural base contour and the effects of coloring them based on tooth position.
