To provide a dental set for open bite treatment, which can easily depress molars in a short period of time without causing extrusion of front teeth when it is necessary to depress molars in open bite treatment, thereby enabling open bite treatment. [Solution] The dental set for open bite treatment has a plurality of brackets (201) attached to the patient's maxillary or mandibular teeth, an orthodontic wire (11) attached to these brackets, and an intermaxillary elastic (400). When indenting a patient's maxillary molars, the intermaxillary elastic is stretched by attaching the orthodontic wire to the bracket attached to the crown of the maxillary canine from above and stretching it, then hooking it from below to the bracket attached to the crown of the mandibular canine, and further hooking it onto a bondable tube (202) attached to the crown of the mandibular first molar. The same applies when indenting a patient's mandibular molars.

The invention discloses an orthodontic device capable of continuously converting masticatory force into anterior tooth adduction force and a using method thereof.The orthodontic device comprises an upper jaw part used for converting masticatory force in the vertical direction into horizontal tension for adduction of anterior teeth, and the upper jaw part is installed on the buccal side of an upper jaw molar area of a patient; one end of the traction accessory is mounted on the upper jaw part, and the other end of the traction accessory is connected to the anterior tooth appliance; and the lower jaw part is fixed on the cheek side of the lower jaw molar area. The masticatory force is used as sustainable output force, the masticatory pressure in the vertical direction is converted into adduction anterior tooth force in the horizontal direction, and meanwhile, molar anchorage protection can be enhanced.

A mandible displacement adjusting device includes an upper braces and a lower braces, wherein the upper braces and the lower braces have an upper teeth accommodation space and a lower teeth accommodation space, the upper teeth accommodation space and the lower teeth accommodation space are made based on the tooth shape, and fits on the upper and lower dental arches of the human body respectively, and the side walls of the upper braces and lower braces extend out a first positioning part and a second positioning part corresponding to the upper molar area and the lower molar area. When the user wear the upper braces and the lower braces, the first positioning part and the second positioning part would be driven to fit together, and maintain a movable displacement space, so that when the mandible of the human body is moved forward and fixed, it will not cause the mandible of the human body due to tightening, neither cause the discomfort at the condyle, while avoiding the back of the tongue slumping down and blocking the breathing passage.

To provide a method for manufacturing an implant having a completely different shape from conventional methods, in which the shape of the implant is adapted to each site where it is to be embedded. [Solution] This is a method for manufacturing an implant (100) used in place of a maxillary molar, which is formed by integrating three separate root equivalent portions (121, 122, 123) with one crown prosthesis portion (150) connected to the base end of the root equivalent portions, and has an abutment (170) attached. One or two vertical grooves (135) having a predetermined depth are formed on the inner surface of each root equivalent portion, extending from the tip of the root toward the base end of the root over approximately one-third of the length of each root equivalent portion, and horizontal grooves (111, 112, 131) of a predetermined depth are formed in a row at predetermined intervals on the surface area of ​​each root equivalent portion, from the underside of the cervical equivalent area formed on the abutment attachment side of the crown prosthesis toward the root tip of each root equivalent portion.

The invention discloses a palate supporting type invisible expansion device and a manufacturing method thereof. The expansion device comprises a palate arch, and tooth sockets capable of being worn on maxillary molar teeth are integrally formed on the two sides of the palate arch; the palate arch comprises a palate part matched with the upper palate structure and a reinforcing part facing the central incisor, the two ends of the palate part are connected with the tooth socket respectively, a layer of grid structure formed by staggered distribution of a plurality of metal wires is arranged in the palate part, and the palate part is provided with at least one oval through hole distributed from front to back along the oral cavity; the upper surface of the reinforcing part is attached to the palate and abuts against the rear portion of the gingiva of the upper central incisor. According to the invention, the expansion effect, the wearing convenience and the comfort are improved.

A personalized healing abutment maker comprises a maker body, the maker body is provided with four groove groups, the shapes of the four groove groups are respectively matched with gum-penetrating contours of four tooth positions of an upper jaw molar, a lower jaw molar, a premolar and an anterior tooth, each groove group at least comprises one groove, and the bottom of each groove is provided with a through hole communicated with the bottom of the maker body. According to the utility model, a plurality of groove groups are arranged, and the proper healing abutment can be formed by pouring glue into the corresponding grooves according to the tooth position of the patient without teeth, so that the adaptation degree of the manufactured healing abutment and the tooth position of the patient without teeth is improved; the problems of unsmooth transition between the abutment and the prosthesis, easy formation of a black triangle, poor abutment stress and the like during later prosthesis making are solved, the physiological and aesthetic requirements of the dental crown are met, the operation is simple and convenient, the dental crown is in place once, a patient does not need to see a doctor for many times, and the time of the patient is saved.

This invention discloses a personalized maxillary and mandibular combined traction device for patients with skeletal Class II high-angle mandibular retrusion, belonging to the field of orthodontics. The device includes personalized maxillary / mandibular titanium plates, elastic traction components, and brackets. Two elastic traction components are included, one for intruding the maxillary molars and the other for tractioning the mandible forward. The maxillary and mandibular titanium plates are positioned at the center of jawbone resistance and are both 3D-printed integrated personalized designs. The elasticity of the traction components can be selected according to needs. This device simultaneously achieves mandibular advancement and maxillary molar intrusion, efficiently enabling early correction of skeletal Class II high-angle mandibular retrusion patients. It also avoids labial tipping of the lower anterior teeth and mesial tilting of the lower posterior teeth. The titanium plates conform to the jawbone, resulting in minimal intraoperative trauma, precise force control, and significantly improved treatment effectiveness and efficiency.

The invention discloses an orthodontic device for pushing maxillary molars backwards based on biological force conversion, which comprises two groups of orthodontic parts which are respectively arranged on two sides in an oral cavity; the orthodontic component comprises an upper jaw component used for converting a masticatory force in the vertical direction into a horizontal pull force capable of pushing an upper jaw molar to move backwards, and the upper jaw component is installed on the cheek side of an upper jaw molar area of a patient; and the lower jaw part is fixed on the cheek side of the lower jaw molar area. According to the invention, the chewing pressure in the vertical direction can be converted into the force for pushing the maxillary molars backwards in the horizontal direction.
