A method and system for designing a dental appliance for an individual. A 3D model of the individual's features including a portion of their face and arches is displayed on a 3D display. The 3D model includes an augmented reality dental appliance. The 3D model can be manipulated by inputs detected by a motion sensor, a brain-computer interface, both, or other sensors. In response to gestures neural activity, or other inputs, the augmented reality dental appliance or other aspects of the 3D model are modified. The 3D model is updated in response to the modified dental appliance or other changes, and repositioned to provide an updated 3D model. The updated 3D model is displayed on the 3D display. This system and method facilitates modification of the augmented reality dental appliance and observation of the resulting aesthetic effects.

A transoral ultrasound probe for imaging a temporomandibular joint and a method of imaging a temporomandibular joint using a transoral probe.

Systems and methods are disclosed in which a diagnostic probe is configured for performing diagnostic measurements and/or therapeutic interventions and for measuring the local surface profile of a local surface region an object. Various example embodiments are described in which the surface profile of the local surface region, when compared to the surface profile of an extended surface region, is employed to provide guidance for positioning and/or orienting the probe when performing a diagnostic measurement. The surface profile within the local surface region may be employed to generate feedback for repeating a previous diagnostic measurement, such that the repeat measurement is performed at the previous location on the object. In other embodiments, surface profile detection is employed to control the positional and/or orientational probe alignment during an iterative tissue removal method in which successive tissue layers are removed when the presence of a pathology is confirmed via a diagnostic measurement.

Certain exemplary ultrasound probe method and/or apparatus embodiments are described, which can be used for 2D and/or 3D imaging soft tissue in an intra oral cavity.

A set of rules to design an orthodontic appliance for generating an aesthetic smile is maintained in a computational device, where the set of rules is associated with an application that executes in the computational device. At least one measured value is computed from one or more features extracted by processing dental information of a patient. The application generates a parameter to design an orthodontic appliance based on the at least one measured value and the set of rules for generating the aesthetic smile.

At least one embodiment of a method for scanning material using a dental ultrasonic imaging probe comprising an ultrasonic device configured for emitting ultrasound signals within at least two emitting cones and for receiving corresponding echoed ultrasound signals, the at least two emitting cones extending in different directions, the method comprising: receiving an item of information relating to a direction for emitting an ultrasound signal; selecting one of the received corresponding echoed ultrasound signals or the ultrasound signals to be emitted as a function of the received item of information.

A surgical apparatus, system and methodology are provided that may be utilized to treat a plurality of medical conditions. A robotic apparatus may be utilized in the treatment of a medical condition or to assist a medical professional in a surgical procedure. Additionally, the robotic apparatus and system may be utilized during a surgical procedure to provide guidance and to narrow the margin of error. In an exemplary embodiment, a scan may first be performed on a patient to determine a plurality of surgically necessary characteristics, such as bone density, locations, and the like. A virtual treatment plan may be provided by the system. An active and/or passive robotic apparatus may be provided to assist in the surgical technique. The robotic apparatus may be an active robotic which includes surgical tools whereby the medical professional may perform the surgical technique with the assistance of the active robotic apparatus.

The invention relates to a dental tray assembly for intraoral imaging of an edentulous dental arch and/or palate. The dental tray assembly includes a base surface and an opposing external surface. An anterior wall is connected to the base surface and extends arcuately either side of a central axis coinciding, in use, with the labial frenulum. A posterior edge connects opposing sides of the anterior wall. The base surface and the anterior wall together define a concave trough for at least partially surrounding an edentulous arch. A spaced-apart array of ultrasound imaging elements is attached to the dental tray within the trough for emitting and receiving ultrasound signals, the received ultrasound signals being representative of the surface topography and/or sub-surface structures of an edentulous dental arch and/or palate to be imaged. Advantageously, by distributing the array of ultrasound imaging elements across the surface area of dental tray the entire edentulous arch and/or palate can be imaged instantaneously. Optionally, received ultrasound signals can be communicated to a remote device, such as a smartphone, running a software App which processes signals to form a virtual digital impression of the dental arches enabling the manufacture of prosthetic dentures having enhanced comfort and stability.
