A dental machining system for manufacturing a dental restoration/appliance, including: a dental tool machine which includes: a dental blank holder for movably holding at least one dental blank relative to one or more dental tools; one or more driving units each for movably holding one or more dental tools, a control unit for controlling the dental blank holder and the driving units based on construction data of the dental restoration/appliance and a plurality of machining processes specific for the manufacturing of the dental restoration/appliance from the dental blank. The control unite executes a trained artificial intelligence algorithm that predicts the machining time for manufacturing the dental restoration/appliance based on input data including: process parameters defining the machining processes respectively; and mappings which include information on the target geometry of the dental restoration/appliance.

A method of machining a dental block (2) by using at least one dental tool (4) to finish or pre-finish a dental restoration (5) at least completely along the equator (5a) with or without a holding stub (5b). The method includes: a step of moving the axis (4a) of the dental tool (4) along a path (6) with an overlaid lateral motion having an amplitude (A), and without separating an unmachined piece (2″) from the rest of the dental block (2). The path (6) lies away from the equator (5a) at least by an amount equal to half of the diameter of the dental tool (4) plus half of the amplitude (A) of the overlaid lateral motion.

What is described is a milling blank having a continuous shade gradient for production of an indirect dental restoration, composed of resin or a resin-based composite. What is also described is a method of producing such a milling blank by mixing two differently coloured pastes with continuous variation of the mixing ratio of the two pastes during the dispensing operation.

A custom tool for forming a dental restoration in a mouth of a patient includes a mold body providing for a customized fit with at least one tooth of the patient. The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth.

Provided is a machinable abutment-integrated prosthetic block. The machinable abutment-integrated prosthetic block is structured such that an abutment is integrated with a crown block made of a material requiring no heat treatment after undergoing machining processing. The abutment and the crown block are integrated by an adhesive layer containing a cured product of a polymerizable organic compound. Therefore, the prosthetic block which is an integrated form of the abutment and the crown block can be processed by machining processing such as CAD/CAM processing. Therefore, the prosthetic block can be processed, by machining processing, into artificial teeth to be used as temporary teeth or permanent teeth and does not require no additional heat treatment after undergoing the machining processing, thereby shortening a treatment time for implant restoration, resulting in a one-day prosthesis procedure.
