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.

In an apparatus for controlling the positioning of an object having a specified point, a first limiter establishes a movable range of the specified point of the object, and limits movement of the specified point of the object within the movable range. The movable range includes a line connecting the position of the specified point of the object and a target position for the specified point of the object. A second limiter limits change of a specified orientation of the object from increasing an angular difference between the specified orientation of the object a target orientation for the specified orientation of the object.

A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. An electronic model of a splint is generated based on the adjusted relative positions of the lower and upper arch dentitions. A splint is then generated in a physical form from the electronic model of the splint.

The intraoral vibratory multifunctional device and wireless system for interaction between device, patient, and dentist, which stands out, among other things, for being comprised by independent segments, so that the applicability of the activation protocols by isolated segments of the arch becomes very simple, and can also be activated together, all segments simultaneously. In short, the invention provides a broad and real time relationship between the dental professional and the patient, in addition to offering other entertainment which could possibly be used. The invention consists of a dental device that has vibration characteristics by means of vibration and a clamping element attached to the dental arch or braces, with the dental braces (AP) composed of microvibrators (1), vibration band (2), and sensors (S1). A remote interaction system provides interactive communication between patient (P), dentist (D1), and the system itself. In short, the invention provides a broad and real time relationship between the dental professional and the patient, in addition to offering other entertainment which could possibly be used.

A system for adjusting a cutting tool includes a cutting system having a cutting tool configured to cut material thermoformed to a dental model. The cutting system is configured to determine, based on a cut line generated for the cutting tool to cut a dental aligner from the material thermoformed onto the dental model, that the cutting tool is incapable of following the cut line. The cutting system is configured to adjust a position of the cutting tool with respect to the cut line so the cutting tool is capable of following the cut line.

A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.

The example systems, methods, and/or computer-readable media described herein help with design of highly accurate models of un-erupted or partially erupted teeth and help fabricate of aligners for un-erupted or partially erupted teeth. Automated agents that use machine learning models to parametrically represent three-dimensional (3d) virtual representations of teeth as 3D descriptors in a 3D descriptor space are provided herein. In some implementations, the automated agents described herein provide instructions to fabricate aligners for at least partially un-erupted teeth using representative 3D descriptor(s) of a tooth type.
