ABSTRACT:
A method for producing a dental bite registration involves the utilization of an alginate dental impression powder composition. The composition is mixed with water in an amount considerably less than the amount of water that would be used for dental impression purposes, and the temperature of the water employed is higher than the temperature of water that would be employed for dental impression purposes. The mixture of the powder composition with water is rapidly blended to form a homogenous lump of dough-like consistency which will not sag but which undergoes plastic deformation. Upon insertion into the oral cavity to record bite registration, the lump hardens in 3-4 minutes.
