The kit for measuring vertical dimension for dental impression provides a tool for measuring a difference between a dental patient's desired vertical dimension and the patient's vertical dimension prior to a dental restoration procedure. The kit includes a base, a plurality of measurement sheets, and dental impression wax. The base includes a planar member having first and second longitudinally opposed ends and opposed upper and lower surfaces. The upper surface has at least one longitudinally extending groove defined therein. First and second legs are secured to the first and second longitudinally opposed ends of the planar member and extend downward from the lower surface. Each measurement sheet has opposed upper and lower surfaces and at least one longitudinally extending rib formed on the lower surface and at least one longitudinally extending groove defined in the upper surface. Each of the plurality of measurement sheets has a known thickness.

Disclosed herein are aqueous dental coating compositions and methods for enhancing contrast of intraoral surfaces for 3-dimensional digital scanning. The compositions include: an aqueous solvent system; a water soluble polymer present at no greater than 5 wt. %, based on the total weight of the aqueous dental coating composition; a plurality of first particles having a first index of refraction, and a plurality of second particles having a second index of refraction different than the first index of refraction, wherein the first particles and the second particles are substantially non-absorptive in the visible range, and wherein the aqueous dental coating composition is a dispersion or a dispersion of the first particles and second particles in the aqueous solvent system can be formed by shaking the composition for 30 seconds.

Disclosed herein are aqueous dental coating compositions and methods for enhancing contrast of intraoral surfaces for 3-dimensional digital scanning. The compositions include: an aqueous solvent system; a water soluble polymer present at no greater than 5 wt. %, based on the total weight of the aqueous dental coating composition; hydrophilic particles; and hydrophobic particles, wherein the aqueous dental coating composition is a dispersion or a dispersion of the hydrophilic particles and hydrophobic particles in the aqueous solvent system can be formed by shaking the composition for 30 seconds.

A method of taking a dental impression of dentition including conditioning a surface comprising one or more of dentition and a dental appliance by the application thereto of a wetting agent to form a controlled hydrophilic wet film. The wetting agent includes water, a surfactant, and an additive. The controlled hydrophilic wet film is hydrophilic and is formed by brushing the wetting agent onto the dentition. The brushing controls the thickness and hydrophilicity of the controlled hydrophilic film to a thickness and hydrophilicity that is capable of inducing flow of an impression material that comes into contact with the controlled hydrophilic film. The flow is sufficient to flow into sub-gingival places. The film is contacted with a dental impression material selected from the group consisting of hydrophilic and hydrophobic dental impression materials.

A system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient is disclosed. The dentition includes a restoration dental arch and an opposing dental arch. The restoration dental arch include the restoration site and the opposing dental arch is opposite the restoration dental arch. The system includes an impression apparatus, a motion capture apparatus, an interface apparatus, and a restoration design system. The impression apparatus is configured to capture an impression of the dentition of the patient. The motion capture apparatus is configured to capture a plurality of location data points that represent the locations of the opposing dental arch relative to the restoration dental arch. The interference model generation system is configured to generate an interference model for the restoration site. The restoration design system is for designing a restoration using the interference model.

Disclosed herein is a dental impression material that includes a two part addition curing silicone composition. The disclosed impression material contains a surfactant system composed of a fluorosurfactant and a fatty alcohol ethoxylate. The impression material disclosed herein exhibits improved storage stability than known systems using fluorosurfactants and silicone ether compounds.
