An orthodontic force measurement system that enables duplication of the patient’s dentition for the application of appliances in a simulated clinical condition. Six components of the load system on individual teeth can be measured. The device can take patient-specific information, such as shapes and locations of the teeth, and duplicate them on the device. Clinicians will be able to apply different appliances to the denture and measure the load system on specific teeth. By accurately quantifying force/moments on individual teeth, individualized, predictable patient-specific orthodontic treatments can be implemented.

The invention relates to a dental model (1) for dental-technical modeling having a model base (2) and having a tooth stump (4) that can be removed from the model base (2), the model base (2) having a receiving cavity (3) for receiving the tooth stump (4), the tooth stump (4) having a preparation section (5), the preparation section (5) being designed for the prosthetic reconstruction of a tooth and the shaft (6) being designed for insertion along an insertion direction into the receiving cavity (3), the model base (2) and/or the shaft (6) having an elastic positioning element for positioning the tooth stump (4) relative to the model base (2).

Continuous adjustment appliances are provided that can store a large number of geometries that can be successively accessed throughout orthodontic treatment, with each geometry can correspond to an arrangement of the patient's teeth. An appliance according to the present disclosure can be stimulated to transition among the myriad geometries, which can include changes to the overall shape of the appliance as well as the position and geometry of the cavities corresponding to a patient's teeth. Methods of creating the continuous adjustment appliances and methods of treatment using the continuous adjustment appliances are also revealed.

Systems and methods are disclosed to prevent interference between two physical tooth models in a physical dental arch model by acquiring the coordinates of a plurality of points on the surfaces of each of the two physical tooth models and digitally representing the surfaces of each of the two physical tooth models by a mesh of points in three dimensions using the acquired coordinates. The meshes representing the surfaces of the two physical tooth models intersect at least at one point to form an overlapping portion. The method also includes calculating the depth of the overlapping portion between the two meshes to quantify the interference of the two physical tooth models.

A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.

Model teeth 20 for a dental model includes a model teeth base 10 provided with a plurality of insertion holes 13 having an inner surface provided with an insertion hole-side step portion 13b such that a deep side of the holes 13 is narrower than an opening side, and a plurality of the teeth 20 having a tooth crown portion 21 exposed from the holes 13 and a tooth root portion 22 inserted inside the holes 13, when the model teeth are detachably inserted into the holes 13, respectively. The teeth 20 include a model teeth-side step portion 26 provided on an outer surface of the portion 22 and cause the teeth 20 to move in a direction such that a distance between adjacent teeth 20 is shortened, as the teeth 20 abut the portion 13b when inserted into the holes 13 and the teeth 20 are inserted deep into the holes 13.

In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.

A method for treating a subject's teeth. A target configuration for the subject's teeth is determined. Receiving features are produced on a dental base in response to the target configuration, the receiving features being configured to receive physical tooth models. The physical tooth models are assembled on the dental base to form a physical arch model. A dental aligner is produced using the physical arch model to move the subject's teeth to the target configuration.

Creating a replacement tooth or set of teeth by using the patient's mouth as an intra-oral articulator. Also, a medical appliance can be created by using the patient's mouth as an intra-oral articulator. A mechanism is fitted within the patient's mouth which can hold one or more replaceable teeth. The dentist adjusts the size, color, location and placement of the teeth within the patient's mouth until a best fit is achieved. Then, the device, with the artificial and temporary teeth secured thereto, is further processed into a final replacement tooth (teeth). Also, the present system can be used for any dental or medical appliance in or about the mouth, i.e., using the mouth of the patient as the intra-oral articulator will result in superior results.
