Abstract
A method for producing dental restoration components includes filling a retort cylinder of a retort system with a forming mass, the retort cylinder being at least partially encircled by a charging body, and hardening the forming mass. After the hardening of the forming mass, the retort cylinder and the charging body are removed from the forming mass, thereby leaving behind a retort. Thereafter, with the assistance of a press blank apparatus, a press blank having an outer contour substantially corresponding to the outer contour of the charging body is pressed into the retort.
Claims20
A method for producing dental restoration components, comprising:
- filling a retort cylinder 14 of a retort system with a forming mass 28, the retort cylinder being at least partially encircled by a charging body 16;
- hardening the forming mass 28;
- after the hardening of the forming mass, removing the retort cylinder 14 and the charging body 16 from the forming mass, thereby leaving behind a retort;
- and
- with the assistance of a press blank apparatus, pressing a press blank having an outer contour substantially corresponding to the outer contour of the charging body 16 into the retort.
A retort system for a meltable model component comprising:
- a generally annularly shaped retort base 12 operable to support a model formed of a mass selected to melt at a melting temperature during a retort preparation process;
- a retort cylinder 14;
- and
- a charging body 16 at least partially encircling the retort cylinder 14, the charging body being formed of a mass selected to melt during the retort preparation process.
A press blank for a retort process comprising:
- a body portion;
- and
- a non-annular outer contour formed on the body portion.
