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.

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.

An example method for detecting stability of a medical implant is provided. The method includes (a) applying a force to the medical implant with a probe, (b) based on the applied force, determining a response signal associated with a vibration of the medical implant, (c) comparing the determined response signal with a computer model of the medical implant, and (d) based on the comparison, determining an angular stiffness coefficient of the medical implant, wherein the angular stiffness coefficient indicates a stability of the medical implant.

The present invention relates to an apparatus and a method of acquiring an image for dental diagnosis. More particularly, the present invention relates to an apparatus and a method of acquiring a near-infrared image for dental diagnosis, wherein an image for dental diagnosis is acquired using near-infrared radiation and a general image camera rather than using X-rays.

It is described an arrangement (230, 330, 430, 530) and a method for tracking a movement of an upper jaw (100) relative to a lower jaw (120), the arrangement comprising: a lower mounting structure (231) mountable relative to the lower jaw (120); at least one lower motion sensor system (233) mounted at the lower mounting structure; and at least one data transmission unit (127) adapted to transmit measurement data (245) from the lower motion sensor system to an analysis unit (239).

An orthodontic system and method for moving and aligning at least one tooth of a set of teeth of at least one of an upper jaw and a lower jaw of a patient. In the system and method an orthodontic appliance can be provided which may include a force exerting member for applying a force to and moving the at least one tooth, a tooth movement sensor member for obtaining at least one of tooth movement data, tooth position data, and tooth identification data, and a tooth movement monitor for calculating at least one of an amount of tooth movement and tooth position from the at least one of the tooth movement data, the tooth position data, and the tooth identification data obtained with the tooth movement sensor arrangement. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member based on the at least one of the tooth movement data, the tooth position data, and the tooth identification data received from the tooth movement monitor.

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.

An orthodontic system and method for aligning at least one tooth of an upper jaw or a lower jaw of a patient. In the system and method at least one orthodontic appliance can be provided which may include at least one force exerting member for applying a force to move the at least one tooth, a tooth movement sensor for obtaining tooth movement data, and a tooth movement monitor for calculating at least one of the distance the at least one tooth has moved and a current position of the at least one tooth from the tooth movement data. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member using the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth.
