The present invention relates to a method of producing a dental restoration from a partially-sintered or non-sintered blank using a three-dimensional dental restoration model, comprising the steps of: generating at least one or more first milling path for rough and/or fine milling; determining areas or zones of increased stress in the three-dimensional dental restoration model and generating at least one modified milling path; machining the blank by milling utilizing one or more first milling paths; selectively machining parts of the blank utilizing at least one modified milling path; and sintering the machined blank.

Method of producing a dental restoration

A system and method for sintering dental restorations. The system can include a monolithic sintering support comprising a surface, and at least one dental restoration positioned in direct contact with the surface of the monolithic sintering support. The method can include providing a monolithic sintering support comprising a surface, positioning a dental restoration in direct contact with the surface, and sintering the dental restoration while the dental restoration is in direct contact with the surface of the monolithic sintering support to form a sintered dental restoration.

System and method for sintering dental restorations

The present invention relates to a device and process for dimensionally stable sintering of ceramic pre-shaped dental articles, the device comprising a suspension system having a base structure with at least one suspension point at a height suitable for suspending an article to be sintered; and a suspension element moveably connected to said suspension point for supporting said article to be sintered, wherein said suspension element itself forms a swing on which said article to be sintered is arrangeable.
