Blank with encoding and method of manufacturing a molded dental component

摘要

A blank for manufacturing molded dental components includes a blank body that includes tooth repairing material. A molded dental component is manufactured by removing portions of the tooth repairing material using a tool. The blank is encoded with at least one structure as a carrier of information regarding properties of the blank body. The at least one structure is arranged such that at least one of a position, dimensions, or a type of structure can be determined by sensing or measuring the blank. In this context, the position, the dimensions, or the type of the structure are embodied such that a value acquired during a determination of the above corresponds to information about a property of the blank body.

主权项

1. A set of blanks for producing dental shaped bodies, said set of blanks comprising:
two or more blanks, each blank including:
a corpus of tooth restoration material, from which a shaped body to be fabricated is carved by a tool adapted to remove the material;a handle protruding from said corpus, said handle providing an axis of rotation of the handle and corpus; anda coding device that includes at least one structure eccentrically mounted relative to said axis of rotation, the at least one structure comprising at least two pairs of depressions or eminences having geometric structures that are predetermined to specify specific, predefined characteristics of the corpus, at least one dimension of the geometric structures being an analog, scaled representation of at least one maximum dimension of the corpus, the at least one dimension of the geometric structures being related to the at least one maximum dimension of the corpus by a conversion factor, wherein each blank of the set of blanks uses the same conversion factor, and wherein at least some blanks of the set of blanks differ with respect to their at least one maximum dimension of the corpus.
