Description

technical field

[0001] The present invention relates to devices, methods and systems for dispensing multi-component flowable dental materials. In particular, the present invention relates to the dispensing of multi-component dental impression materials for making dental models. Background technique

[0002] Devices for dispensing single and multiple component flowable substances are well known in the art.

[0003] For example, several hand-held dispensing devices designed for dispensing flowable construction materials such as fillers, adhesives, and the like are known in the art. For example, German Patent No. 3437306 describes a motor-driven, single-component hand-held device for dispensing build materials such as sealant, adhesive or putty. The device includes a region for receiving a cartridge containing construction material, and a drive member for pushing said material forwardly from the forward end of the cartridge. Unlike the usual use of a rigid piston as the driv...
