A current digital dental model is received that includes a representation of the set of physical teeth for the patient with the current dental appliance attached to the physical teeth or oral cavity. The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.

Dental preparation uses a tooth preparation guide custom-made liar fitting with teeth of a patient. The preparation guide includes one or more guide channels for guiding a cutting tool. The preparation guide enables modification of the teeth as planned with high level of precision. A dental prosthesis for installing onto prepared teeth of the patient is provided before preparation of the teeth. The prosthesis includes features that are complementary to the prepared teeth. The prosthesis can be installed immediately after preparing the teeth using the preparation guide. With the high level of accuracy and precision in the preparation of teeth, no modification of the prosthesis would be needed for installation.

Disclosed are an apparatus and method for setting a margin line and a recording medium, wherein the apparatus and method set a margin line corresponding to the outline of the boundary between a tooth and a prosthesis on the basis of three-dimensional virtual model data of the tooth obtained by using a three-dimensional scanner such as an oral scanner or the like. The method for setting a margin line according to an embodiment of the present disclosure, comprises the steps of: generating curve information about the peripheral area of the margin line candidate points selected in a three-dimensional virtual model obtained for a tooth; and setting a margin line indicating the outline of the boundary between the tooth and a prosthesis on the basis of the curve information.

A dental articulator includes a first arm hingedly joined to a second arm about a pivot axis, where each one of the first arm and the second arm are configured to mount a dental model comprising at least one measurement element, and an inspection tool capable of checking the at least one measurable element against allowable tolerances. Each arm includes a mounting bracket having a distal portion adapted to mount the respective dental model and having a proximal portion. Each arm further has a base member having a distal portion adapted to hingedly join the first arm and the second arm about the pivot axis. The inspection tool comprises a first measurement device and a second measurement device. The first measurement device is coupled to the first arm or second arm and the second measurement device is coupled to the first arm or second arm.

The present disclosure relates to a method and device for matching oral model data that can provide matching points to a user to match oral model data and computerized tomography (CT) data even for edentulous patients. In this way, convenience is increased and matched data can be effectively generated even for edentulous patients for whom matching has been difficult conventionally.

Disclosed herein is a preliminary guide including an impression resin and a guide tray. The guide tray includes an impression resin accommodation part, a jig fastening part, a protective cover part, and a grip part.

According to the present disclosure, partial precision shape data is added to overall data by combining scan data obtained by a first scanner and a second scanner, respectively, and thus, missing data in a scan of the first scanner is supplemented by a scan of the second scanner. There is an advantage of being able to derive highly reliable data through such a supplementary process, and a user can provide a more suitable treatment to the patient.

A method of visualizing a treatment of teeth includes maintaining a final position model trained to output movement of teeth from initial to final positions, receiving from a user device a first representation comprising teeth of a user in an initial position where the first representation is based on a 2D image transmitted from the user device, determining tooth movements of the teeth from the initial position to a final position using to the final position model, receiving by the user device a graphical visualization of a treatment plan for moving the teeth of the user where the graphical visualization is generated based on the final position and the treatment plan is suitable for correcting the user's malocclusion, and displaying by the user device the graphical visualization where the graphical visualization comprises a three-dimensional (3D) representation corresponding to the teeth of the user.

A scan body with healing abutment for coupling to an implanted dental component includes: a scannable portion; a healing abutment portion; and a skirt positioned between the scannable portion and the healing abutment portion, the skirt having an upper surface containing scannable indicia. The scannable portion is positioned at an apical end of the healing abutment portion and comprises a tapered body; and the healing abutment portion comprises a lower surface of the skirt and a tapered hollow cuff extending from the lower surface of the skirt toward a distal end.

Systems and methods of simulating dental treatments are disclosed. A method may include capturing a first 2D image of a patient's face, including the patient's teeth, building a parametric 3D model of the patient's teeth and gingiva based on the first 2D image, developing a simulated outcome of a dental treatment of the patient's teeth by rendering the parametric 3D model with the patient's teeth in one or more positions and/or orientations corresponding to the treatment goals of the dental treatment plan, and rendering a second 2D image of the patient's face with gingiva and teeth according to a simulated outcome of the dental treatment plan. As noted herein, the dental treatment plan may include orthodontic and/or restorative elements. The simulated outcome may correspond to estimated outcomes and/or intended outcomes of the dental treatment plan.
