The invention discloses a personalized orthodontic appliance having an orthoaxis function, which comprises No.1 to No.7 personalized orthodontic lingual brackets connected in series with each other by an arch wire. Each personalized orthodontic lingual bracket comprises a base plate and a bracket body portion connected with the base plate. Among the No.1 to No.7 personalized orthodontic lingual brackets, towing hooks with through holes are arranged on the lower sides of the bracket body portions of at least two personalized orthodontic lingual brackets, and the through holes are connected together in series through an axis correction wire. The towing hooks with the through holes are arranged on the lower sides of the bracket body portions of the personalized orthodontic appliance having the orthoaxis function, and the orthoaxis wire penetrates through the through holes, so that corresponding orthodontic force is produced on the lower sides of the bracket body portions while the dentalcrown moves in the orthodontic process, thereby gradually correcting the positions of the roots of teeth and avoiding the inclination of teeth in the distal movement process; therefore, the personalized orthodontic appliance has the orthoaxis function. Besides, the personalized orthodontic appliance is simple and smart in structure, good in axis correction effect, and thus suitable for dental extraction cases in personalized orthodontic therapy.

Provided is a novel and creative dental tissue regeneration method for regenerating dental tissue after pulpectomy or the enlargement and cleaning of an infected root canal. After pulpectomy or the enlargement and cleaning of an infected root canal, a root canal filler (200) having an extracellular matrix (210) containing the cells (220) enriched for dental pulp stem cells, is inserted into the apical side of the root canal of a target tooth (100). The cells including dental pulp stem cells include at least one of the following: dental pulp SP cells, CD31-negative and CD146-negative cells, CD24-positive cells, CD105-positive cells, and CD150-positive cells. For instance, dental pulp SP cells are CD31− and CD146− negative. Even if pulpitis due to deep caries occurs, appropriate dental pulp regeneration and recovery of dental pulp function are possible.

The invention discloses a stomatological tooth extraction auxiliary device, and relates to the technical field of stomatological equipment. The stomatological tooth extraction auxiliary device comprises a first support frame and a second support frame. The bottom of a side of the first support frame is rotationally connected with the bottom of a side of the second support frame by fixing shafts, asupport seat is fixedly connected with the top of the right side of the first support frame, a hollow plate is rotationally connected with the outside of the support seat, a sponge sleeve sleeves thesurfaces of the hollow plate and is positioned below the support seat, and a guide tube is communicated with the right side of the hollow plate and is positioned between the support seat and the sponge sleeve. The stomatological tooth extraction auxiliary device has the advantages that the tongues of patients can be compressed by the aid of the hollow plate, and accordingly influence on tooth extraction and even injury to the tongues due to movement of the tongues when the patients feel painful can be prevented; saliva can be absorbed by the sponge sleeve and can be sucked into a liquid storage tank by the aid of the guide tube, accordingly, the problems that saliva is difficult to shallow due to mouth opening and patients are chocked with the saliva can be solved, and the saliva can be prevented from interfering with tooth extraction.

The invention relates to a degradable tooth extraction wound filling composition, a preparation method and application thereof, and is characterized in that it comprises the following raw materials in parts by weight: 20-60 parts of calcium stearate, 10-40 parts of alginic acid / chitosan composite, biological 5 to 30 parts of active glass, 10 to 60 parts of tocopherol acetate, and 0 to 30 parts of poloxamer; including the following steps: mechanically mixing calcium stearate, alginic acid / chitosan composite, bioactive glass, poloxamer loxamer, then add tocopherol acetate, mix evenly to form a marl-like mixture, and obtain a degradable tooth extraction wound filling composition after shaping, packaging and sterilization; Composition for preventing tooth extraction complications. The degradable tooth extraction wound filling composition of the invention is a putty-like material that can be arbitrarily shaped and deformed, can fill tooth extraction sockets of any shape, has a long action time, stabilizes the hemostatic effect, and at the same time has the functions of repairing and bacteriostasis.

The invention relates to a stomatological tool, in particular to novel stomatological illuminable multifunctional tooth forceps which comprises a tooth forceps body, oral supporting and lighting equipment, a labor-saving fulcrum, extension equipment and a hand protection rubber mat. The tooth forceps can provide lighting in the process of tooth extraction for the convenience of a dentist to replace and observe teeth; in a circumstance that tooth roots are long and difficult in force applying, form of the tooth forceps can be changed to generate a supporting point, so that convenience is brought to a doctor to applying force; the tooth forceps can be demounted into an oral supporting device, so that closing of the mouth of a patient can be prevented for the convenience of the doctor to observe. The tooth forceps body and the oral supporting and lighting equipment are meshed through a thread, the labor-saving fulcrum is mounted on the tooth forceps body, the extension equipment is mounted inside the tooth forceps body, and the hand protection rubber mat and the tooth forceps body are in fixed contact connection.

The present invention discloses an individualized orthodontic appliance with axis correction functions, comprising No. 1-7 individualized lingual brackets connected in series by an archwire. Each individualized lingual bracket includes a base plate and a bracket body connected with the base plate. In the No. 1-7 individualized lingual brackets, the underside of the bracket body of at least two of the individualized lingual brackets is disposed with a crimpable hook with a through hole and the through holes are connected in series by an ortho-axial wire. In this invention, the underside of the bracket body is disposed with the crimpable hook with the through hole and the ortho-axial wire is used to pass through the through holes. In this way, the underside of the bracket body can produce the corresponding orthodontic force while the crown of tooth is moving during the orthodontic treatment. The positions of the teeth roots can also be gradually corrected. It prevents teeth from inclining when they move far from the center; therefore the correction function is achieved. The structure of the individualized orthodontic appliance provided by the invention is simple and ingenious, the axis correction function is excellent and it is applicable to patients with dental extraction in the individualized orthodontic treatment.

The invention belongs to the field of dentistry and particularly relates to a dental tooth extraction method. The dental tooth extraction method comprises the following steps: step one, carrying out oral disinfection on a patient and administering an anesthetic; step two, letting the patient sit on a tooth extraction chair, adjusting the chair position and aligning to a light source to make the patient be at a comfortable position; exposing surgical field to facilitate operation; step three: preparing a tooth extraction device: a gingival separator, a dental elevator, dental forceps and a curet; step four: separating gingiva, loosing tooth root, extracting offending teeth and extracting broken roots; step five: after the teeth are extracted, scraping granulation tissues and foreign mattersin a tooth socket by using the curet, and scratching the wound to enable oozed blood to fill the tooth socket; then pressing buccal and lingual gingiva to reset with fingers; finally, covering the wound with a sterile sand strip or a cotton roll.
