The present invention relates to a dental blank, in particular a parallelepipedal block, having an upper surface and a lower surface, which is composed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least a portion of the surfaces of the blank.

A medical or dental treatment device comprises a tool retainer, a measuring coil and an evaluation device. The tool retainer can be connected to a plurality of different tools. The measuring coil can be supplied with a periodic electrical energy. The evaluation device can be connected to the measuring coil for detecting whether a tool is connected to the treatment device or which of a plurality of tools is connected to the treatment device. On the basis of an electromagnetic (e.g., inductive) coupling between the tool accommodated in the tool retainer and the measuring coil supplied with the periodic energy, a periodic measurement signal specific to each tool can be generated and assigned by the evaluation device to the tool. The evaluation device determines the phase shift of the electrical voltage and of the electric current of the periodic measurement signal.

The present invention provides an improved orthodontic bracket with integrated piezosensor chip determining even the slightest change in initial installation setup of orthodontic bracket system and further notifying the subscriber electronically comprising of orthodontic bracket, for holding the tooth; at least one wire, for connecting the orthodontic brackets; and at least one sensor chip placed on the bracket and/or on the wire, wherein, at least one pulse oximeter is installed at the periphery of the bracket base to ensure force applied are within biological limits; the invention provides a detachable wireless frequency transmitter to be placed on the bracket of tie-wing to permit clinical recycling of the bracket; and optionally allowing a handheld laser scanner/photospectrometer to measure the frictional coefficient between the archwire and bracket to determine exact amount of force required for tooth retraction; to determine the bonding technique for detecting voids in adhesive; and to determine the distance between forces applied and center of mass of the tooth.

The present invention relates to a method and a system for managing dental article information based on a UHF RFID, and more particularly, to a method and a system for managing dental article information based on a UHF RFID, capable of automatically monitoring a location, a stock, and an expiration date of an article used by medical staffs of a dental clinic without an additional action of the medical staff, and providing information and a notification related to a dental article to the medical staffs of the dental clinic.

A device comprising an orthodontic or dental appliance for use with a system for information management in dentistry, a system for storing and managing dentistry data such as information about an orthodontic or dental treatment of a person using a private network and a method for information management in dentistry are described.

A dental device tracking method including acquiring, using an imager of a dental device, at least a first image which includes an image of at least one user body portion outside of a user's oral cavity; identifying the at least one user body portion in the first image; and determining, using the at least the first image, a position of the dental device with respect to the at least one user body portion.

Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of orthodontic-elements, such as orthodontic-brackets, orthodontic-archwires, orthodontic-expanders, orthodontic-elastic-bands, and orthodontic-power-chains, to name a few, in a non-invasive and contactless way, with respect to monitoring; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in or attached to such orthodontic-elements. Such arrangements may permit monitoring of forces acting on teeth by various orthodontic-elements. Using backscatter imaging technology, the structural integrity and other states of the orthodontic-elements may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized backscatter-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the orthodontic-elements.

A medical treatment apparatus includes a power and control (PAC) device. The PAC device provides electrical power through a cable to a laser handpiece assembly to electrically power a laser source within the handpiece assembly. The PAC device controls operation of the handpiece assembly and detects an identification of the handpiece assembly. The PAC device also monitors data relating to operation of the handpiece assembly. The PAC device uploads, through a communication network to a user assistance center remote from the PAC device, the handpiece assembly identification and the monitored data.

A dental device tracking method including acquiring, using an imager of a dental device, at least a first image which includes an image of at least one user body portion outside of a user’s oral cavity; identifying the at least one user body portion in the first image; and determining, using the at least the first image, a position of the dental device with respect to the at least one user body portion.

A dental instrument water supply filter includes a hollow cylindrical body which bounds an interior area. The interior area houses a plurality of iodinated resin particles. A pair of water permeable discs are positioned in the interior area of the body at opposed axial ends. End caps close the interior area of the body at the respective opposed ends, and each end cap includes a respective removable fluid fitting. Water that is used in connection with the operation of a dental instrument is passed through the filter. The filter provides filtration and reduces microorganisms in the water that is passed therethrough and also releases ions into the water that are effective to reduce the growth of contaminants in the water lines to the instrument.
