A method is of designing a virtual three-dimensional (3D) model of a mold for a dental appliance. The method includes determining an identifier to be associated with the mold. The mold includes a dental arch portion associated with teeth of a user. The dental arch portion includes a first distal portion, a second distal portion, and an incisor portion disposed between the first distal portion and the second distal portion. The method further includes determining, based on the identifier, a label to be formed in a label portion of a beam of the mold. The method further includes determining a placement of the beam. The beam extends from the first distal portion to the second distal portion in the virtual 3D model of the mold.

The application discloses a simulation oral cavity model, relates to the technical field of oral cavity models, and comprises a model base, a middle tooth area corresponding to the middle part of a jaw bone, a molar area corresponding to the two sides of the jaw bone, a middle body installed in the middle tooth area, and incisors and canines installed on the middle body; a stabilizing strip plate is fixedly arranged in the molar area of the model base and is provided with insertion grooves in the two side walls; two side edge bodies are installed with double canines and molars, the bottom of each side edge body is provided with a sliding groove, a clamping block is fixedly arranged on the inner wall of the sliding groove, the stabilizing strip plate can slide into the sliding groove, the clamping block abuts against the inner wall of the insertion groove, and the side edge body can be fixedly installed with the middle body; when the side edge body abuts against the middle body, the side edge body is connected with the side wall of the model base, and the side edge body is connected with the side wall of the middle body. The application has the effects of diversified display of oral cavity pathologies and cost saving.

This utility model discloses a protective sleeve for supporting laryngeal surgery, comprising a deformable sheet, a contact pad fixedly installed on the inner side of the deformable sheet, and a protective pad fixedly installed on one side of the deformable sheet. The protective pad includes a buffer layer, a pressure-resistant layer, and a wear-resistant layer. The buffer layer covers one side of the deformable sheet, the pressure-resistant layer covers one side of the buffer layer, and the wear-resistant layer covers one side of the pressure-resistant layer. This utility model involves placing the contact pad on the outside of the patient's upper incisors, with the protective pad facing outwards. The deformable sheet is then pinched against the outside of the upper incisors, allowing the deformable sheet and contact pad to conform to the shape of the patient's upper incisors. At this point, the contact pad is in close contact with the upper incisors, preventing separation. The protective pad blocks the front side of the deformable sheet, and when the upper incisors are used as a support point for the laryngoscope, it isolates the laryngoscope from the upper incisors and provides a cushioning effect, reducing patient discomfort.

This invention discloses a medical anti-displacement temperature measuring dental pad, comprising a dental pad body. The side wall of the dental pad body has an arc-shaped concave groove, and the inner wall of the dental pad body has two C-shaped guide rope holes, located on opposite sides of the arc-shaped concave groove. An installation groove is formed on the inner wall of the dental pad body away from the arc-shaped concave groove. Through the segmented and precise layout of the C-shaped guide rope holes, the rope loop, after passing through the guide rope holes, forms two independent and cooperative fixing points on the inner and outer sides of the incisors. The dual-point fixing structure works synergistically to restrict the dental pad's rotational freedom and displacement space, ensuring the dental pad remains stable and preventing displacement due to unconscious patient movements. Simultaneously, the dual-point fixing structure securely confines the endotracheal tube within the arc-shaped concave groove of the dental pad, ensuring a tight fit between the endotracheal tube and the dental pad. This not only prevents dental pad rotational displacement but also effectively protects the endotracheal tube from being bitten or crushed.

The utility model relates to the technical field of dentistry. The tooth socket with the expansion and front traction functions comprises a tooth socket base body, and the tooth socket base body comprises a first molar coating part, a first transition connecting part, a middle incisor coating part, a second transition connecting part and a second molar coating part which are connected in sequence; the first transition connecting part and the second transition connecting part are provided with hollow structures; the first molar coating part and the second molar coating part are connected through an expansion arch structure, and the middle part of the expansion arch structure is a bending structure which is arranged in a roundabout manner; traction connecting pieces for front traction are fixed on the lip side of the first molar coating part and the lip side of the second molar coating part, and the traction connecting pieces are limiting buckles or tubular structures. According to the utility model, the structure of the tooth socket is optimized, the arch expansion function is realized through the arch expansion structure, and the front traction function is realized through the traction connecting piece, so that the arch expansion function and the front traction function are integrated on the tooth socket.

A kind of dental appliance is provided with multiple rings for being sleeved in deciduous teeth or permanent teeth and as fixed point, connecting device, traction hook for traction permanent teeth to be corrected, tongue bar for forming with the resistance area of tongue to avoid the forward extension of tongue and fixing hook for being fixed with permanent teeth to be corrected, ring is fixedly connected with the connecting device, traction hook is fixedly connected with at least one ring, tongue bar is fixedly equipped in connecting device and is located in the lingual side of incisor, and fixing hook is buckled with traction hook by connecting piece.The dental appliance forms multiple tension fixed points, corrects permanent teeth to be corrected, improves the force stability of permanent teeth to be corrected, and reduces the stress of other teeth, reduces the risk of deciduous teeth loosening and falling off.Moreover, the dental appliance forms the resistance area of tongue with the tongue bar, avoids the inadvertent forward extension of tongue, and further avoids the bad habits such as tongue extension, licking teeth, sucking fingers and primary tongue spitting, so as to improve the correction effect.

The present application belongs to an improved orthodontic device and its treatment method for bimaxillary protrusion. The problems to be solved are: the difficulty in anchorage control, the large side effect of molar loss and the patient's discomfort and complicated operation during the treatment of bimaxillary protrusion. The technical points are: the upper and lower central incisors, lateral incisors, canines and first permanent molars are bonded with ordinary transmission appliance brackets; the upper and lower circular wire main arch wires are in circular arc shape, with two small loop curves and two backward bends, passing through the slot of the ordinary transmission appliance bracket; the upper front tooth retraction coil connects the small loop curve on the upper circular wire main arch wire and the lower anchorage molar; the lower front tooth retraction coil connects the small loop curve on the lower circular wire main arch wire and the upper anchorage molar. The orthodontic method comprises the following steps: step A, bracket bonding; step B, arch wire bending; step C, elastic coil installation; step D, treatment process. It is suitable for the orthodontic treatment of bimaxillary protrusion cases.
