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.

A dental procedure simulator includes a support structure and a linkage suspended from the support structure. The linkage is controlled by a computer that is configured to simulate a dental procedure or treatment. A handpiece is coupled to the linkage and configured to be held in a hand of a user and to be manipulated by the user in a workspace (W) in real space. The phenom head is provided with a phantom upper jaw and a phantom lower jaw (14) and is supported by the support structure and arranged in the workspace (W.) The phantom lower jaw is arranged movably relative to the phantom upper jaw.

A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

Personal dental scanning systems for treatment of teeth are provided. These dental scanning systems may be configured for use by a user (e.g., patient) without requiring a dental professional and may include a scanner, a user input a user output, and one or more local or remote processors.

A portable tooth-sensitivity demonstration apparatus and a process. The apparatus includes a main unit with a top cover having at least one tooth station thereon; an electrical circuit, a sensitivity indicator, and an on/off switch. A sensor in the tooth station is part of the electrical circuit to activate a response by the sensitivity indicator. A water-permeable tooth piece, treated with an oral-care product, is placed into the tooth station, and a few drops of water are deposited on top of the tooth piece. Lack of response from the sensitivity indicator shows an absence of sensitivity and hence effectiveness of the oral-care product, while a response from the sensitivity indicator shows existing sensitivity and thus failure of the oral-care product to seal the tooth piece. In an apparatus having multiple tooth stations, different oral-care products can be assessed simultaneously and side-by-side.

An orthodontic practice appliance (1) in the present invention includes an orthodontic tooth row (23) for orthodontic practice, an orthodontic gingival part (22) that holds the orthodontic tooth row (23) and is softened by the application of heat, and a metal member (24) that is placed inside the orthodontic gingival part (22) and has an exposure portion exposed to the outside. According to the present invention, when the orthodontic practice appliance (1) is immersed in hot water, the exposed metal member (24) is heated. The metal member (24) extends inside the orthodontic gingival part (22). Therefore, the orthodontic gingival part (22) is heated not only from the surface thereof in direct contact with the hot water but also from inside thereof by heat transmitted through the heated metal plate (24). Accordingly, heat is transmitted to the orthodontic gingival part (22) uniformly.

Simulators for practicing trans-oral surgery and methods of use thereof, are described. The simulator may include a simulated soft palate musculature adjacent to the simulated hard palate, and a simulated mucosal layer covering at least a portion of the simulated hard palate and at least a portion of the simulated soft palate musculature, wherein the simulated mucosal layer is configured to conform to and follow the contours of surface features of the covered portions of the simulated hard palate and simulated soft palate musculature.

Existing haptic-based simulation systems struggle to replicate a realistic experience for dental and dental hygiene students and clinicians. A realistic haptic-based simulator to train periodontal procedures. Realism is accomplished through three distinguished features: (1) a custom grip to attach dental instruments to the haptic device, which enhances the grip experience since learners feel the tactile properties of the instruments (rather than the haptic device stylus), (2) two haptic devices are utilized to simulate haptic feedback with both the dental instrument (dominant hand) and the mirror instrument (non-dominant hand), and (3) a finger support mechanism using parallel manipulation is used for the intraoral fulcrum during probing. The Haptic dental simulator system comprises software and hardware subsystems. The software subsystem comprises of two Graphical User Interface (GUI) windows: the configuration window where an instructor defines periodontal exercises for learners to practice with and a simulation window where periodontal exercises are displayed for learners to interact with. The hardware subsystem includes two haptic devices with grips having the real instruments, and the finger support device.

A method of demonstrating the impact of a treatment on a surface comprising the steps of: i optionally imaging at least one untreated surface ii applying at least one treatment to the surface(s)such that if step i) is not performed at least two different surfaces are treated with differing treatments, iii imaging the treated surface(s) to create an image; iv converting the imaging data into a format suitable to create a magnified image on a 3D printer; v producing a 3D model of each of the imaged surface(s).

Methods for simulating orthodontic treatment are provided. In some embodiments, a method includes capturing a first representation, the first representation including a depiction of a patient's teeth. The method can include building a parametric model of the patient's teeth based on the first representation, using one or more case-specific parameters for one or more shapes associated with at least one of the patient's teeth. The method can also include simulating an outcome of a dental treatment plan for the patient's teeth to produce a simulated outcome of the dental treatment plan. The method can further include modifying the parametric model to provide a modified model representing the simulated outcome of the dental treatment plan.
