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.

A dental model and related systems and methods, including a first component representing a portion of a patient's jaw and a second component that is demountably attachable to the first component, and a second component representing a dental structure of interest, such as the remaining portion of a tooth or a dental implant.

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 includes a model teeth-side step portion 26 provided on an outer surface of the portion 22 and causes the teeth 20 to move in a direction distance between adjacent teeth 20 is shortened, as the teeth 20 abuts the portion 13b when inserted into the holes 13 and the teeth 20 is inserted deep into the holes 13.

The present invention of a digital dental implant replica for a dental model manufactured with 3D additive technology and a system relates to a digital dental implant replica to simulate the position of the dental implant in a dental model which has been produced by means of 3D printing processes or CAD/CAM systems, providing greater precision and maneuverability with respect to analog systems in the orientation of the implant in the dental model due to a simple retention system which is easy to use and detachable.

The invention relates to a tooth stump for a dental model, said dental model comprises at least one tooth and at least one tooth stump receptacle for at least partially receiving the tooth stump, said tooth stump comprises a tooth portion in the form of a human or animal tooth and a coupling portion defining a coupling portion longitudinal axis for force-locking and/or positive-locking engagement with the at least one tooth stump receptacle of the dental model in a coupling position, the tooth stump comprising a positioning device for defined spatial positioning of the tooth stump in the tooth stump receptacle in the coupling position, wherein the positioning device comprises at least one positioning element formed on the coupling portion. Further, the invention relates to a dental model.

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.

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.
