The invention relates to oral care equipment which comprises a handle extending along a first axis and a flushing head movably arranged at the end of the handle. The handle comprises a shell and a movement device arranged in the shell; the movement device comprises a driving assembly, a transmission assembly and a movement shaft. The driving assembly comprises a driving motor installed in the shell. The transmission assembly is driven by the driving motor to move in the axial direction of the driving motor. A hollow runner extending along a first axis is arranged in the moving shaft; the moving shaft is installed on the transmission assembly and extends along the first axis to be connected with the flushing head. The moving shaft drives the flushing head to move along the first axis under the action of the transmission assembly; and liquid is pumped to the flushing head through the hollow flow channel. According to the flushing head, the limitation that the spraying direction of a traditional fixed flushing head is single is broken through, the reciprocating motion of the flushing head can simulate the scraping action of a floss pick between tooth seams, and the cleaning effect on areas such as tooth adjacent surfaces and gingival sulcus is improved.

The invention discloses an invisible tooth socket assembly which comprises a first invisible tooth socket matched with a first tooth jaw, a second invisible tooth socket matched with a second tooth jaw and a guide plate, and the first invisible tooth socket comprises a first buccal labial surface, a first lingual surface and a first contact surface connected with the first buccal labial surface and the first lingual surface; the second invisible tooth socket comprises a mounting surface corresponding to an adjacent tooth gap of the second tooth jaw, the guide plate is connected with the mounting surface, and when the first invisible tooth socket and the second invisible tooth socket are in an occlusion state, the guide plate abuts against the first contact surface so as to realize lowering, leading or retracting of the first tooth jaw. The guide plate is arranged corresponding to the adjacent tooth gap of the second tooth jaw, so that when the first invisible tooth socket and the second invisible tooth socket are in an occlusion state, no matter which area of the first contact surface is propped by the guide plate, the guide plate can apply acting force to the first contact surface; the first contact surface can transfer the acting force to the first tooth jaw so as to realize lowering, leading or retracting of the first tooth jaw.

The utility model discloses a kind of transparent mouthguard type push missing tooth side molar distal upright device, which is convenient and comfortable, comprising a transparent mouthguard and a double-curved tongue spring that covers all teeth in the interproximal space. One end of the double-curved tongue spring is fixed to one end of the transparent mouthguard near the interproximal space, and the other end of the double-curved tongue spring is a pressure application end. The transparent mouthguard covers the clinical crown, and while ensuring aesthetics and comfort, the force transmission is more direct, the fixation force is more stable, and the anchorage control is more controllable. The double-curved tongue spring achieves precise and efficient molar movement through a local force application mechanism, significantly shortening the time required for interproximal space expansion before implantation. The device uses digital oral scanning combined with 3D printing technology to quickly produce the orthodontic device. Doctors do not need to perform complex operations to customize the device. It is suitable for patients who do not need orthodontic treatment or cannot accept full orthodontic treatment. The transparent mouthguard in the device uses domestic hot plastic film and domestic orthodontic materials, which is cost-effective and has a short preparation period.

The application discloses a kind of occlusion process tooth abutment area gap detection method and system, belong to stomatology field, specifically include: collection detector mouth inlay area target tooth crown three-dimensional surface data and three-dimensional cheek side occlusion data;The three-dimensional scanning data described above is handled to obtain inlay area crown three-dimensional surface data after occlusion;Fusion the inlay area crown three-dimensional surface data before occlusion and the inlay area crown three-dimensional surface data after occlusion, obtain inlay area before and after occlusion tooth abutment area gap change feature;Obtain the abutment area gap of inlay area before and after occlusion tooth or non-inlay area before and after occlusion tooth before and after occlusion.The application carries out early data collection using mouth three-dimensional scanning technology, then combines area-line-point-line-area data processing process, accurately extracts the abutment area gap of adjacent tooth in mouth before and after occlusion Change feature, with quantifiable, repeatability, objectivity and the like features.

The application discloses a kind of interdental space maintaining material and its processing method, belong to oral prosthetic material technical field.The material includes successively from inside to outside: metal base layer, functional response layer and bioceramic protective layer.The metal base layer uses low sensitization cobalt-chromium base alloy;The functional response layer is distributed on the surface of metal base layer, and it contains microscale energy storage cavity array, and cavity is filled with the pH response type drug-loaded gel consisting of pH sensitive polymer matrix and inorganic mineralization precursor particles;The bioceramic protective layer is coated outside the functional response layer, and has through microporous structure.The application also provides the processing method of the material.The application can intelligently release mineralizing substances under oral acid environment by constructing pH-ion pump bidirectional regulation mechanism, in-situ plugs metal ion leakage and neutralizes acid environment, significantly improves the biological safety, mechanical stability and caries prevention ability of the material, especially suitable for children in mixed dentition period.
