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 includes features for adjusting the energy applied to an energy application tool to compensate for the physical characteristics or type of the object, and/or for orientation of the device relative to the horizontal during measurement. 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.

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 includes 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.

A processing device may execute instructions from a computer readable medium to perform operations comprising: making a comparison between first image data of at least a portion of a dental arch and second image data of at least the portion of the dental arch; determining a plurality of differences between a first representation of at least the portion of the dental arch in the first image data and a second representation of at least the portion of the dental arch in the second image data; determining that a first difference of the plurality of differences is attributable to tooth movement; determining that a second difference of the plurality of differences is attributable to tooth wear to one or more teeth on at least a portion of the dental arch; and generating a third representation of at least the portion of the dental arch that is a modified version of the second representation, wherein a visual indication of the tooth wear is provided in the third representation.

A system includes a scanner configured to generate image data of dental arches, a data store configured to store the image data, and a computing device. The computing device is to: perform an analysis of a representation of a dental arch from first image data and a second representation of the dental arch from second image data; determine that gingival recession has occurred at first regions and that tooth wear has occurred at second regions based on the analysis; generate a first color visual overlay that identifies the first regions; generate a second color visual overlay that identifies the second regions; receive user selection of at least one type of clinical issue on the dental arch; and output, to a display and in accordance with the user selection, the representation of the dental arch and at least one of the first color visual overlay or the second color visual overlay.

Systems and methods for monitoring a patient's teeth during orthodontic treatment, which may include the use of a series of appliances according to a corresponding series of treatment stages. The system may include a device in communication with one or more sensors of a first appliance implementing a particular treatment stage. The device may be configured to receive monitoring data corresponding to sensor data captured at the one or more sensors, where the sensor data is associated with at least one parameter related to a change in position or movement of the teeth. The device may further be configured to predict tooth positions or movements based on the sensor data, and compare the predicted tooth positions or movements to expected tooth positions or movements. The device may additionally be configured to determine that the first appliance should be replaced with a second appliance based on the comparison.

A motion adjustment prediction system is described. A scan of a dentition is performed to generate a digital dental model from which a position and orientation of each tooth in the upper and lower dental arches of the dentition is determined with respect to each other tooth. A dentition motion assessment is performed to capture motion data representing a movement of the dental arches relative to each other. A dental treatment plan with dentition adjustment is determined based on the scan and the dentition motion assessment. The dentition adjustment can include a restoration preparation, such as a crown or a bridge, or can include an orthodontic alignment. A motion adjustment is predicted based on the dentition adjustment, and the dental treatment plan is modified based on the predicted motion adjustment.

Systems and methods for monitoring a patient's teeth during orthodontic treatment, which may include an orthodontic appliance having one or more sensors configured to sense at least one parameter related to a change in movement and/or position of one or more teeth of the patient's teeth. One or more processors may be configured to receive sensor data captured by the one or more sensors while the orthodontic appliance is worn on the patient's teeth. The sensor data may be converted to predicted tooth position and/or movement associated with the one or more teeth. The predicted tooth position and/or movement may be compared to an expected tooth position and/or movement of the one or more teeth. Based on the comparison, a determination may be made that the orthodontic treatment should be modified or that the orthodontic appliance should be replaced.
