A method and system for receiving a dental radiographic image that includes an oral structure, and in an image processor, selecting a segmenter and an object detector, predicting masks and points of the oral structure using the segmenter and the object detector to become part of image metadata. The dental radiographic image and image metadata are further provided to a measurement processor for selecting at least one measurement method of a set of measurement methods according to the dental radiographic image and the image metadata, calculating a sensor pixel to mm (millimeter) ratio using the measurement method, and calculating a calibrated measurement of the oral structure.

The invention provides a bionic oral cavity structure for testing and application of the bionic oral cavity structure, and solves the technical problem that an existing bionic oral cavity structure needs to be improved in actual testing. The bionic oral cavity structure for testing comprises an upper jaw, a lower jaw, a driving unit, a sensor and a controller, and the structure is characterized inthat a gingiva part is made of a soft elastic material, a base body of the gingiva part is provided with a through hole and a cap part formed by extending upwards from an upper end opening of the through hole; a tooth part comprises molars and an implant all made of a hard material, the upper end of the implant penetrates the through hole of the gingiva and then extends into the cap part; the gingiva part and the implant are detachably fixed on a mounting plate, the sensor is a flexible sensor, and covers the cap part, a counter bore is formed in the bottom of each molar, the molars are mounted on the gingival part , and an integral body formed by the flexible sensor, the cap part and the upper end of the implant is embedded into the counter bore and is in close fit with the counter bore.

The present invention relates to a cleaning device for an electric toothbrush for oral insertion. The electric toothbrush for oral insertion comprises a toothbrush body part including first teeth insertion grooves into which the upper teeth of a user are inserted and second teeth insertion grooves into which the lower teeth of the user are inserted. The toothbrush body part includes a plurality of toothbrush bristles which are formed to have different lengths in the first teeth insertion grooves and the second teeth insertion grooves on the basis of a teeth model part shaped according to the teeth of the user. Therefore, the toothbrush bristles are shaped according to the shape of the teeth and the oral cavity structure of the user, thus making it possible to wash away foreign matter between the user's teeth even when the user has an uneven set of teeth. The electric toothbrush for oral insertion is kept constantly clean by being disinfected and sterilized for predetermined periods of time using a body holder for holding the electric toothbrush for oral insertion. Moreover, the electric toothbrush for oral insertion can be wirelessly recharged when held in the body holder, thus enhancing convenience.

An oral care device is described for contacting or transferring a dental composition to the hard or soft surfaces of the teeth comprising a backing layer and a discontinuous pattern of a dentally therapeutic composition. A method of using said oral care device to effectuate an aesthetic or therapeutic treatment is also described, whereby the oral care device is placed against the surface of at least one oral cavity structure, the discontinuous pattern of dentally therapeutic composition is contacted with or transferred to said structure. The backing layer may be left in place during the treatment period, or optionally removed from the oral cavity while leaving the therapeutic composition in contact with the target structure.

A device is disclosed to assist in making a customized intraoral positioning device IPD to be positioned within a mouth of a patient in accordance with a prescribed radiation therapy treatment plan for a head and / or neck of the patient, the prescribed radiation therapy treatment plan including an incisor separation and / or tongue position of the patient, the device comprising: a base unit configured to be positioned between upper and lower arches in the patient's mouth, wherein the base unit includes an arch section for incisor separation in a deployed configuration in the patient's mouth and first and second arms that extending from the arch unit; a handle extending from the base unit to enable a user to grasp the device so that the user may introduce and remove the device from the patient's mouth; and one or more bite blocks configured on the arch section of the base unit so as to increase the height of the arch section in accordance with the incisor separation of the prescribed radiation therapy treatment plan, to thereby enable a user to obtain records of the position for dental and oral structure within the patient's mouth including a relationship between the upper and lower arches at the prescribed incisor separation.

The invention relates to the field of measuring tools and discloses a multifunctional orthodontic measuring assembly. The multi-functional orthodontic measurement component can integrate measurement tools such as vernier calipers, rulers and protractors, and realize the collection of various measurement functions. At the same time, the optimized design is carried out according to the anatomical characteristics of the stomatognathic system, which can make the orthodontic measurement component more consistent with the oral cavity structure, thereby making it easy to use and operate, and greatly improving the convenience and accuracy of the orthodontic measurement work.

Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and / or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and / or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.
