Abstract
The disclosed waxing guide is in the form of a thin flat element having a central line formed thereon. The guide is placed beneath the dental cast with the central line centered between maxillary central incisors on the dental cast. Lines spaced outwardly from the central line indicate the apparent width of the central incisor, the adjacent lateral incisor, and the adjacent canine tooth and first bicuspid, when viewed from the front. Each of the spaces has the same ratio of 1:1.618 with the adjacent spaces.
