Orthodontic systems for monitoring treatment. The systems can include at least one orthodontic appliance that includes one or more sensors. A processor in communication with the sensor(s) is configured to receive sensor data from the sensor(s), where the sensor data corresponds to a force acting on one or more teeth. The processor is further configured to predict tooth movement based on the sensor data. The predicted tooth movement is determined by predicting how much teeth will move based on a direction and a magnitude of the force. The processor is further configured to compare the predicted tooth movement to an expected tooth movement, where the expected tooth movement is based on a treatment stage of a treatment plan. The processor is further configured to modify the treatment plan if the predicted tooth movement does not match the expected tooth movement based on the treatment stage of the treatment plan.

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.

A manually operable apparatus for measuring tooth mobility utilizing an alveolar ridge clamped and a tooth clamp. A positioning rod of the alveolar clamp serves as an anchor. A metering rod of the tooth indicates tooth mobility to a gage when force is applied to the same.

Provided are a system, method, and computer readable storage medium for using a digital reconstruction of a tooth, wherein the digital reconstruction includes a crown and a root. An image of the crown of the tooth is acquired, subsequent to a movement of the tooth. The shape data of the crown is extracted from the image and registered to the digital reconstruction of the tooth.

Method and Apparatuses for monitoring progress of an orthodontic treatment plan and automatically or semi-automatically modifying the orthodontic treatment plan. The orthodontic treatment plan may be monitored by sensors on one or more appliance in the treatment plan, and may be monitored if the sensed data deviates from the expected treatment plan.

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.

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.
