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.
Claims14
A retort system comprising:
- a generally annularly shaped retort cover (30) operable to support a model formed of a mass selected to melt at a melting temperature during a retort preparation process;
- a retort base (12) including 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, and further comprising a spacer body (46) disposed between the charging body (16) and the retort cylinder (14), the spacer body being meltable at a melting condition corresponding to that of the melting condition of the charging body (16).
A retort system comprising:
- a generally annularly shaped retort cover (30) operable to support a model formed of a mass selected to melt at a melting temperature during a retort preparation process;
- a retort base (12) including 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 and further comprising a spacer body (46) for maintaining the space between the charging body (16) and the retort base (12), and a coding indicia associated with the spacer body (46) indicating via color indicia, information concerning an aspect of the spacer body (46) differentiating the spacer body (46) from other spacer bodies (46) including at least one of the predetermined length and the predetermined outer diameter of the spacer component.
