Plastic sticks and hollow plastic sticks are used as a casting reservoir in the sprue technique for casting
They stabilise the wax-up when using the lift-off technique for crowns and bridges, can be easily shaped over a flame, and burn out leaving no residue
Hollow sticks are used in metal-ceramic work for non-precious alloys and alloys with a reduced precious metal content, especially in larger multi-unit constructions
Please view pictures for different types available.
