A system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient is disclosed. The dentition includes a restoration dental arch and an opposing dental arch. The restoration dental arch include the restoration site and the opposing dental arch is opposite the restoration dental arch. The system includes an impression apparatus, a motion capture apparatus, an interface apparatus, and a restoration design system. The impression apparatus is configured to capture an impression of the dentition of the patient. The motion capture apparatus is configured to capture a plurality of location data points that represent the locations of the opposing dental arch relative to the restoration dental arch. The interference model generation system is configured to generate an interference model for the restoration site. The restoration design system is for designing a restoration using the interference model.

Methods and apparatuses for monitoring either or both the performance of an orthodontic appliance for repositioning a patient's teeth and/or the user compliance in wearing the appliance using a biosensor. The apparatuses described herein may include one or more sensors, including biosensors, electrical sensors, or both, configured to generate sensor data related to user compliance and/or repositioning of the patient's teeth by an orthodontic appliance.

A method for obtaining an orthodontic treatment plan is provided. The method comprises obtaining a treatment plan for treatment of a tooth of a patient, the treatment plan including two or more stage force values, wherein each of the two or more stage force values is based on a target orthodontic force value that is based on one or more determinate points of periodontal ligament (PDL) behavior data. For each of the two or more stage force values, the method includes determining configuration parameters for configuring an orthodontic appliance to apply the stage force value to a tooth of the patient; and, using the configuration parameters to manufacture an orthodontic appliance configured to apply the stage force value.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system does not include an external on/off switch or any remote on/off switching mechanism. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

This invention is a device to monitor caloric intake comprising: a wearable member that is worn in a manner similar to eyeglasses; and an EEG sensor, wherein indications that a person is probably eating are based on electromagnetic waves from the person's brain. In an example, this device can further comprise one or more automatic-imaging members that automatically take pictures when the person eats based on data from the EEG sensor.

A system for developing a dental treatment plan includes a dental treatment plan generator that compares basic jaw measurements with a dataset of human jaw size and motion. The system includes a parametric model of jaw motion divided into representative segments that can be compared to a patient's jaw measurement to generate a dental treatment plan that reduces interference and need for adjustment during the course of treatment.

The present disclosure provides a device for measuring a stability of an implant system. The device includes a housing configured to be positioned adjacent the implant system. The device also includes an actuator coupled to the housing. The actuator is configured to vibrate the implant system when actuated. The device also includes a motion sensor coupled to the housing, and a controller in communication with the motion sensor and the actuator. The controller includes at least one processor, and data storage including program instructions stored thereon that when executed by the at least one processor, cause the controller to perform functions including: (i) receiving motion data from the motion sensor when the actuator is actuated, and (ii) determining an angular stiffness of the implant system based on the motion data.

Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.
