The present disclosure discusses techniques for fabricating bite interference elements within polymeric dental appliances. The techniques disclose at least one polymeric shell that includes a number of cavities shaped to fit over a patient's teeth. The polymeric shell includes an occlusal appliance surface shaped to fit over an occlusal tooth surface of the patient. One or more bite interference elements are formed within the occlusal appliance surface, and each bite interference element includes a partially disc-shaped feature extending radially away from the occlusal tooth surface when worn by the patient.

The invention discloses a wearable mouth breathing intelligent appliance and a breathing frequency monitoring system thereof, and relates to the field of snore-ceasing devices, the wearable mouth breathing intelligent appliance comprises a U-shaped occluder, an upper jaw abutting block and a supporting piece, and further comprises an air flow channel with one end communicated with the U-shaped occluder and the other end communicated with the upper jaw abutting block, and a flow control part arranged on the supporting piece and arranged outside the air flow channel in a sleeving mode; the vibration component is arranged on the supporting piece; the monitoring device comprises a lip pressure monitoring part arranged on the outer wall of the U-shaped occluder, a tongue pressure monitoring part arranged at the bottom of the upper jaw abutting block and a first airflow monitoring part arranged at an inlet of the airflow channel; the device further comprises a second airflow monitoring component attached to the lower portion of the nose. According to the scheme, through highly-integrated hardware design and intelligent closed-loop control, accurate recognition and self-adaptive intervention of the breathing mode are achieved, and the technical defects that a traditional appliance is passive and single and lacks safety monitoring are effectively overcome.

The invention discloses a simulation device and method for an occluder mold, which are suitable for simulating the occluder mold in a three-dimensional virtual space, and the simulation device comprises a transceiver circuit, a memory and a processor. The processor executes the following steps: obtaining a plurality of reference positions respectively corresponding to a plurality of tooth occlusion states from a plurality of dentition three-dimensional model diagrams; generating a target position according to the plurality of reference positions and the plurality of two-dimensional occlusion images; and generating a new dentition three-dimensional model diagram corresponding to the target occlusion state according to the target position, and establishing an occluder target model of the new dentition three-dimensional model diagram. Therefore, the medical risk caused by the operation of the patient and the reduction of the curative effect after the operation can be avoided.

The utility model relates to liquid injection device technical field discloses an integral elbow nozzle, including nozzle part and elbow part, the nozzle part includes nozzle body, and the step shaft is shaped on nozzle body, and the annular clamping groove that cross section is right trapezoidal shape is shaped to the step of step shaft, the elbow part includes the vertical joint part and horizontal joint part of integral forming, and vertical joint part and horizontal joint part inside hollow and both communicate to set up, and vertical joint part inserts the small end shaft on step shaft and both clearance fit connection, the lower end inner edge of vertical joint part is shaped with the convex ring, and the lower end of convex ring is shaped with the inside fold ring, and inside fold ring inserts in annular clamping groove, the elastic occlusion ware is equipped in horizontal joint part inside. To solve the problem of high procurement cost, inconvenient installation, poor sealing performance in the prior art, realize the effect of reducing procurement cost, improving installation efficiency and enhancing sealing performance.

The invention provides a head positioning device for neurosurgery detection, and belongs to the technical field of neurosurgery medical equipment. Comprising a shell, a first electric sliding rail is installed at the front end of the shell in a nested mode, a head fixing mechanism is installed at the output end of the first electric sliding rail, a second electric sliding rail is transversely installed at the front end of the shell, and the head fixing mechanism is used for positioning and fixing the head of a patient; the front end of the shell is provided with a noise reduction mechanism, the noise reduction mechanism is arranged below the head fixing mechanism, and the noise reduction mechanism is used for fixing ears on the two sides of the head of the patient and reducing noise to relieve the nervous mood of the patient. The two sides of the ears of the patient are fixed through the noise reduction mechanism, the problems of physical sound insulation and psychological stress are solved, the oral cavity of the patient bites the occluder through the occlusion fixing mechanism, the lower jaw of the patient is supported, the head of the patient is prevented from moving slightly, and the stability of detection data is effectively improved.

Provided are a dental model and an articulator having a model tooth having a root portion identical to an actual tooth and capable of being attached and detached from a gum portion. The dental model (1) of the present invention comprises: a gum portion (12) provided with an insertion hole (20) for inserting a model tooth (50); and a cover portion (18) provided inside the insertion hole (20) in the gum portion (12). In a closed state, the cover portion constitutes a portion of the gum portion (12). In an open state, the cover portion forms a recess (18b) that is continuous with the insertion hole (20) and exposes at least a portion of the root portion of the model tooth (50). The cover portion opens and closes relative to the other portions of the gum portion (12).

The utility model provides an occluder which comprises a body and an occlusion portion arranged at the near end of the body, a plurality of protruding blocks are arranged on the outer surface of the occlusion portion, the protruding blocks are arranged in at least two rows, and each row of protruding blocks are arranged in an arc shape. According to the utility model, the at least two rows of bumps are arranged on the outer surface of the occlusion part, and each row of bumps are arranged in an arc shape, so that the occlusion device adapts to the shape of the upper row or the lower row of teeth of a patient, the friction force with the teeth is effectively increased, the occlusion device is prevented from falling off from the mouth of the patient, and the use stability is still kept even during movement.
