Dental systems and methods related to impressionless dental modeling. A dental modeling system includes a dental model base and a mounting plate. The dental model base includes a plate support surface and a plurality of pin receiving apertures formed in the support surface. The mounting plate includes a plate portion positioned on the plate support surface and a plurality of pins extending into the pin receiving apertures to provide removable attachment of the mounting plate to the dental model base. The plate portion includes a model support surface configured to support a model of a person's teeth. The model may be formed directly on the model support surface using an impressionless technique. The model may be formed separately using an impressionless technique and then bonded to the model support surface.

A low profile winged impression post having snap-in features eliminates the need for individual impressions of the mandibular and maxillary arches as well as a separate bite registration when registering a dental implant. The low profile impression post is retained by a press fit which eliminates the cumbersome task of screwing in the implant post. The time and steps needed to produce a stone model for construction are shortened. The same low profile impression post can be scanned optically for accurate placement in a virtual three dimensional space model of the jaw. A physical model can be generated in rigid polymer from the virtual scan data.

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 tool for forming a dental restoration includes a mold body configured to combine with a tooth of a patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth. In some examples, the portion of desired tooth structure defines an interproximal surface of the tooth. The mold body may include, in some examples, a base member configured to provide a customized fit with at least one tooth of the patient to attach the mold body to the at least one tooth, and an interproximal member extending from the base member and configured to be disposed between adjacent teeth of the patient when the base member is fit over the at least one tooth. The interproximal member defines a surface of the mold cavity.

An articulator for dental use includes a first base, a second base coupled to the first base, and an occlusion pin configured to couple the first base and the second base in a closed position. The first base includes a first base body including a first groove configured to receive plaster, a first hinge portion configured to extend outwardly from one end of the first base body, and a plurality of pin holes. The second base includes a second base body including a second groove configured to receive the plaster, a second hinge portion configured to extend outwardly from one end of the second base body, and a plurality of guide pin holes. The second hinge portion is configured to couple to the first hinge portion via the occlusion pin in the closed position.

The invention relates to a method for producing a dental model for removable insertion in a recess of a holder, which dental model has a referencing, comprising at least one tooth part having a base to be inserted into the recess, wherein the at least one tooth part is produced using digitized data of a jaw in that the digitized data are saved in a computer beforehand and supplied to a processing machine to produce the at least one tooth part. In order to ensure simple handling of the dental model and in particular to prevent faulty insertion of the dental model or segment, according to the invention the referencing is saved in the computer and, in consideration of the referencing, the at least one tooth part is produced as having the base as a unit.

There is described an oral device for augmenting a user's lip. The oral device includes an arcuate body formed such that a shape of the arcuate body is a cast of a shape of at least a portion of a gum of a user. The body has a height such that, when the body is positioned against the at least a portion of the gum, the body does not overlap with at least part of a visible portion of at least one of the user's teeth. The oral device may include retaining members for retaining the oral device in the user's mouth. The oral device may be printed using a 3D printer.

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.

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.
