A method of designing a patient-specific prosthesis for a current patient includes receiving scan data of a mouth of the current patient to identify conditions at a location at which the patient-specific prosthesis is to be placed on a dental implant, and determining at least two clinical factors for the current patient. The method further includes identifying a desired outcome for soft tissue for the current patient at the location, and accessing a database having soft-tissue-outcome information for each of a plurality of previous patients. The database further includes clinical-factor information for each of the plurality of previous patients. Based on the soft-tissue-outcome information and the clinical-factor information for at least one of the plurality of previous patients being related to the current patient's desired outcome and the current patient's at least two clinical factors, the method includes developing a design for the patient-specific prosthesis for the current patient.

Methods for manufacturing a dental restoration for a patient and dental ceramics production devices are disclosed. A dental restoration may be designed based on a scan of the patient's mouth, using a CAD software module. The software module may produce conveyor channels for a positive model based on the dimensions of a muffle in relation to the size and shape of the positive model. The conveyor channels may extend at an angle of between 0 and 130 away from an axis of the pressing channel, the axis being located essentially along an isotherm inside the muffle. A docking site may be selected based on a position with the greatest wall thickness of the positive model. The present disclosure allows the creation of a high-quality dental restoration in a very efficient fashion, in particular when lithium disilicate is used as the dental ceramics material.

In a method for automated positioning of a blank in a processing machine provided with a housing and a spindle unit with an electric motor, a control unit for control and electrical supply of the processing machine, a computer producing processing programs for manufacturing workpieces, a workpiece holder, and an image recording unit that optically records image data of a blank received in the workpiece holder, a blank is fixed in the processing machine and the image recording unit produces an image of the blank. A division of the blank into an already processed region and into an unprocessed region based on the image data of the image is performed. A workpiece geometry to be produced is assigned to the unprocessed region of the blank, and a milling operation is performed on the unprocessed region. In a variant of the method, the image recording unit is separate from the processing unit.

A wax model of a required coping is produced using CNC machining techniques based on a virtual model of the coping created from digital data obtained from the intraoral cavity. The dental coping is then fabricated from the wax model.

A physical model of at least a portion of a patient's dentition has model dental surfaces corresponding to real dental surfaces of the patient's dentition. The physical model includes one or more targets, each configured for facilitating placement of an orthodontic appliance on the model at a desired location. The targets lack mechanical stops that are outwardly protruding from the original model dental surfaces. Also provided are a method of manufacturing a physical model for use in indirect bonding procedures, a method for indirect bonding for use in an orthodontic procedure, a method for providing an indirect bonding transfer tray for use in an orthodontic procedure, and a system for providing a physical model for use in indirect bonding orthodontic procedures.

A dental milling machine is provided with a tool which is guided in a chuck. A workpiece arm is mounted opposite the tool to be able to be moved at least in the direction of the spindle axis. With a control device it can be moved in relation to the workpiece, especially by means of a drive motor of the workpiece arm.

The workpiece arm has an abutment element, whereby the control device moves the tool and the abutment element towards each other until they abut each other. The control device can be used to detect abutment of the abutment element with respect to the tool, in particular with respect to its tip, in particular by decelerating the (relative) movement of the tool and the abutment element towards each another, upon contact of the tool and the abutment element. This position may be signaled as a reference position and, especially may be stored.

A method of manufacturing customized ceramic labial/lingual orthodontic brackets by digital light processing, said method comprises measuring dentition data of a profile of teeth of a patient, wherein measuring dentition data is performed using a CT scanner or intra-oral scanner, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model on a computer, designing a 3D CAD bracket structure model for a single labial or lingual bracket structure, importing the 3D CAD bracket structure model into a Digital Light Processing (DLP) machine, directly producing the bracket by layer manufacturing.

The invention relates to a method for the computer-assisted manufacturing of a dental replacement part or a dental auxiliary element from a blank, which can be rotated about an axis of rotation, by means of a machining tool, wherein a blank data set comprising the axis of rotation and a model data set of the dental replacement part or dental auxiliary element are stored and the model data set has a first region having a first insertion axis and a second region having a second insertion axis askew to the first insertion axis, wherein in a first positioning step (S1) the model data set is arranged in the blank data set in such a way that the first insertion axis of the model data set is oriented perpendicular to the axis of rotation of the blank data set and in a second positioning step (S2) the second insertion axis of the model data set is oriented perpendicular to the axis of rotation of the blank data set by rotating the model data set about the first insertion axis.
