Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically an automatic mixing machine for impression materials. Background Technology

[0002] Impression material is the material used to take oral impressions. This material should be elastic, with good flowability and plasticity; its physical properties should be stable after solidification, with no change in shape or volume; the solidification time should be appropriate; it should be easy to remove from the mouth after solidification; it should not chemically react with the model material and should be easily separated; it should be easy to handle, clean, and disinfect; and it should have no irritating effect on oral tissues. The traditional method for mixing impression material is by manual stirring.
