A dental bite block device includes a front wall, a flat lateral sidewall, and a concave lateral sidewall that define a longitudinal channel that extends through the device. The lateral sidewalls are connected by a crossbar, and the channel can be filled with polyvinyl siloxane (PVS) dental impression putty. When the device is positioned in the patient's mouth, the flat lateral sidewall faces the right inner check of the patient, the patient's tongue rests against the concave lateral sidewall, and the patient's upper and lower teeth rest open on the front wall. Once the PVS putty sets, it forms a solid half cylinder-shaped member that includes impressions of a plurality of the patient's upper and lower teeth, which assist to maintain the device in place. The front wall and concave sidewall further include an opening that defines a clip for a saliva ejector.

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.

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.
