  • Patent number: 9693845
    Abstract: A system and method for real-time measurement of curing energy delivered to a simulated dental restoration from a source of curing energy. The system comprises a detector and a display. The detector measures at a location within the simulated dental restoration the amount of curing energy delivered by the curing energy source. The display displays the measured amount of curing energy in real-time. The system also comprises a temperature detector to measure temperature changes in the oral tissues during curing (teeth and gums). The system also comprises a video camera to record the operator's curing technique.

  • Patent number: 9277979
    Abstract: The dental position tracking system includes a toothbrush (30) which has a system (20) for determining the orientation of the toothbrush in the mouth of a user relative to the earth, based on measured stored information. Information is stored in the toothbrush concerning target ranges of expected measured toothbrush orientations for each of a plurality of dental zones (22). A processor (24) compares the measured toothbrush orientation information with the target orientation ranges, following conversion of both the target orientation information and the measured toothbrush orientation information to the same coordinate system. The processor then determines which if any of the target ranges matches, within a selected tolerance thereof, with the toothbrush orientation information. Any difference between the target range and the measured toothbrush orientation information is then used to partially adjust the target information range, in order to compensate for a change of position of the user's head.

More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding.

    Abstract: System and method for teaching a dental practitioner an appropriate pressure to apply during a dental procedure. The system includes a dental tool for use in a dental procedure and a substrate including a coating of a removable scratch-off material. The scratch-off material is adhered to the substrate so as to have an adherence strength that is specifically configured so that the scratch-off material coating is removable from the substrate by manipulating the dental tool against the scratch-off material coating upon application of a minimum threshold pressure that is substantially equal to that to be applied during a selected actual dental procedure. In this manner, an inexperienced practitioner is able to learn the appropriate magnitude of pressure to be applied during a procedure (e.g., application and burnishing of a hemostatic composition into bleeding soft tissue) in a non-threatening environment without having to actually work on a live, bleeding patient.

  • Publication number: 20130177887
    Abstract: A simulator for simulating treatment of biological tissue comprises a real handle with three degrees of freedom of both translation and rotation, a screen for displaying a model of the treatment area and a virtual handle, a motion detection device for detecting the three-dimensional motion of the real handle, and a computer having a simulation program that displays the virtual handle on the screen in spatial relation to the biological tissue on the basis of the motion of the real handle detected by the motion detection device. The real handle simulates a laser head that emits a laser beam for treating the biological tissue. The simulation program calculates an impinging surface of the laser beam on the biological tissue based on the spatial relation and laser parameters and calculates an energy density distribution of the laser beam within the impinging surface. The removal of tissue is displayed on the screen.

  • Publication number: 20130059278
    Abstract: The invention provides a dental model with an artificial jawbone with cavities, at least two artificial teeth, and interfaces each connecting a corresponding tooth to the jawbone such that it extends upwards from a corresponding cavity. To enable movement of the teeth relative to the jawbone and relative to the other teeth, the teeth are connected to the jawbone via interfaces which are more elastically deformable than the teeth and jawbone. In this way, a realistic dental model can be made in a very simple and cost efficient manner, e.g. in an SLS process. The invention further provides a method of making the dental model.

  • Publication number: 20130052625
    Abstract: The invention relates to a method for producing a set of shell appliances for correcting tooth misalignments in a patient, wherein a target position is established from a current position of the patient's teeth, models of the patient's individual teeth or of groups of the patient's teeth are produced and can be arranged on a support to form a model of a set of teeth. In accordance with the invention, a set of supports is produced, which have a respective fitting position for each of the tooth models, the position and alignments of said fitting positions predefining a position of the tooth model, wherein the positions predefined by the supports form a sequence that leads in steps to the target position, and the tooth models are fitted in succession onto the individual supports, thus producing a respective model of a set of teeth, and a shell appliance is produced from each of these models of a set of teeth by thermoforming.

  • Patent number: 8376753
    Abstract: The invention relates to a method and device for learning and training dental treatment techniques, according to which a force is applied to a tooth (2) preferably by means of tools (4) in order to examine or treat this tooth. A mandible (1) or the tooth (2) is coupled to a force measuring device (3) in a manner that enables the forces applied to the tooth (2) to be represented in the form of electric measurement signals (5) that are fed to a data processing device (6). Said data processing device has a data memory (7) in which a multitude of reference force/time courses of different force/time-determined tooth treatment steps can be stored in a manner that enables them to be retrieved, whereby the forces applied to the tooth (2) and their temporal course are compared with a reference force/time course.

  • Patent number: 8277224
    Abstract: A dental articulator for use in dental education simulates the human mouth and has an adjustable hinge that interconnects upper and lower carrier trays for movement to and from a closed position. Modules of imitation gums and teeth are secured in the carrier trays by neodymium magnets. The hinge structure in the articulator is selectively movable to shift the jaw axis to a position to provide the desired alignment of the upper and lower teeth when the jaw is closed or demonstrate a misaligned condition. A dental training module may be installed which, upon removal from the articulator, has a pair of separable sections encasing a tooth to permit release of the tooth and removal from the module so that a completed treatment may be evaluated.

  • Patent number: 8267695
    Abstract: The present invention relates to a tooth which is used in a dental arch model with which dental students can experience dental works in the oral cavity and practice treatments. More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding.
