摘要： A method and system for applying colored dental adhesive and a high-resolution decal to the surface of a person's tooth. The colored dental adhesive is formed by combining dental adhesive with a food grade colorant. The high-resolution decal is formed by printing a design on a paper substrate. Before application of the colored dental adhesive, the tooth is cleaned and etched with a phosphoric acid compound. The colored dental adhesive is applied to the surface of a tooth. The decal is then placed on colored dental adhesive, and the colored dental adhesive is cured. Additional layers of dental adhesive may be applied on top of the decal.

摘要： A holder for a dental crown. The dental crown holder may comprise a handle and a working end, where the working end has at least one extension arm extending therefrom. The dental crown holder may be used by covering the working end of the dental crown holder, including the extension arms, in a curable material; placing the dental crown into the curable material such that at least a portion of the extension arms and at least a portion of the curable material are located inside an interior surface of the dental crown; and curing the curable material. The dental crown holder with cured curable material may thus securely hold the dental crown without any slipping, rotating, or wobbling, allowing the user to make adjustments to the dental crown while holding the handle of the dental crown holder rather than the dental crown itself.
