[0018] Optionally, the anterior teeth positioning member is a positioning screw; and a threaded hole matching the positioning screw is provided on the anterior teeth alveolar socket;

[0019] In the fixed position, the positioning screw is tightened and abuts against the traumatic tooth model, and the traumatic tooth model does not loosen; in the loosened position, the positioning screw is loosened and away from the traumatic tooth model, and the traumatic tooth model loosens.

[0020] Optionally, a root apex magnet is also provided at the root position of the upper front teeth, and a corresponding alveolar socket bottom magnet is also provided inside the anterior tooth alveolar socket, and the root apex magnet and the alveolar socket bottom magnet are adsorbed to fix the tooth model.

[0021] Optionally, the complete tooth model is a complete upper right lateral incisor tooth model, and a first magnet is placed on the labial side of the middle part of the root;

[0022] A second magnet corresponding to the first magnet is arranged at the labial gingival margin of the right maxillary incisor alveolar socket of the right maxillary bone fracture model and / or the right maxillary complete model.

[0023] Optionally, the labial bone plate of the right maxillary central incisor alveolar socket of the right maxillary bone plate fracture model is in a separated state, and both ends of the gingival edge of the bone plate are connected to the alveolar bone plates on both sides by connecting axes;

[0024] Furthermore, a magnet is embedded in the root edge of the bone plate, and after the separated bone plate is reset, the corresponding alveolar process is placed in the magnet, which is adsorbed and positioned with the bone plate magnet.

[0025] Optionally, the left maxillary central incisor alveolar socket of the enlarged left maxillary alveolar socket model is 1 mm wider and 2 mm deeper than the left maxillary central incisor alveolar socket of the complete left maxillary bone model, so as to simulate the impaction state after the traumatized tooth is placed.

[0026] Optionally, the dental teaching simulation mold also includes: a mandibular mold, used in conjunction with the maxillary mold.

[0027] The usage of this model is as follows:

[0028] 1. Simulation of lateral displacement injury type: The right maxillary model uses the right maxillary bone plate fracture model 1-a, and the left maxillary model uses the left maxillary alveolar socket enlargement model or the left maxillary complete model according to the need of simulating injury. The complete tooth model of the right upper central incisor is placed in the alveolar socket, the root protrudes from the alveolar socket labially, the root apex magnet is attracted to the magnet, and the labial bone plate end is separated from the alveolar process, simulating the injury state of the lateral displacement of the tooth and the bone plate. During the resetting operation, the root is pressed back into the alveolar socket, and the root apex magnet is attracted to the magnet at the bottom of the alveolar socket; at the same time, the labial bone plate is repositioned, and the magnet at the end of the bone plate is attracted to the magnet, showing the position of the tooth and the state of the bone plate after resetting.

[0029] 2. Simulation of partial dislocation injury type: The right maxillary model uses a right maxillary bone plate fracture model or a right maxillary complete model. The right upper lateral incisor is placed in the alveolar socket, and the labial magnet of the root is attracted to the labial edge magnet of the alveolar socket. At this time, the tooth position simulates a partial dislocation injury. During the operation practice, the right upper lateral incisor in this position is reset to the alveolar socket, and the root tip magnet is attracted to the bottom magnet of the alveolar socket to simulate the normal position after reset.

[0030] 3. According to the type of simulated trauma, different half-maxillary models are matched and combined into a complete maxillary dental trauma model through the maxillary magnetic suction device. Match according to whether there is damage to the alveolar socket. For example: if there is lateral displacement injury and intrusion injury, the right maxillary bone plate fracture model + left maxillary alveolar socket enlargement model are combined; if there is lateral displacement injury but no intrusion injury, the right maxillary bone plate fracture model + left maxillary complete model are combined; if there is no lateral displacement but intrusion injury, the right maxillary complete model + left maxillary alveolar socket enlargement model are combined; if there is no lateral displacement and no intrusion injury, the right maxillary complete model and the left maxillary complete model are combined.

[0031] 4. In this model, there is a gap of about 0.2mm to 0.3mm between the right maxillary bone plate fracture model, the left maxillary alveolar socket enlargement model, the right maxillary complete model and the left maxillary complete model. Therefore, after the tooth root is completely placed in the alveolar socket and the apex magnet and the alveolar socket bottom magnet are adsorbed and fixed, the tooth model is in a loose state, simulating the looseness after periodontal tissue damage. When the tooth needs to simulate the damage without periodontal tissue damage and looseness, the anterior tooth positioning piece on the palatal side of the alveolar socket, that is, the screw device, can be tightened; if the looseness after periodontal tissue damage needs to be simulated, the anterior tooth positioning piece, that is, the screw device, can be loosened.

[0032] If it is necessary to simulate a certain tooth or pulp tissue damage, the complete tooth model in the corresponding alveolar socket can be replaced with a broken tooth model. For example, to simulate a crown fracture and pulp exposure, the original complete tooth model of the upper left central incisor in the upper left central incisor alveolar socket can be replaced with a "crown fracture and pulp exposure" model of the upper left central incisor.

[0033] The technical solution of the present invention has the following advantages:

[0034] 1. The dental teaching simulation mold provided by the present invention comprises:

[0035] A half maxillary mold comprises: a right maxillary bone plate fracture model, a left maxillary alveolar socket enlargement model, a right maxillary complete model and a left maxillary complete model; wherein adjacent models are detachably connected to form a maxillary mold, comprising: the right maxillary bone plate fracture model and the left maxillary alveolar socket enlargement model, the right maxillary bone plate fracture model and the left maxillary complete model, the right maxillary complete model and the left maxillary alveolar socket enlargement model, as well as the right maxillary complete model and the left maxillary complete model, simulating 4 situations of multiple tooth positions with different injury types and traumatic teeth in the maxillary anterior area.

[0036] In the present invention, the maxillary mold with the assembled structure can effectively simulate crown-root fracture, crown-root fracture, root fracture, enamel-dentin fracture, etc., and simulate periodontal tissue trauma, including tooth concussion, subluxation, partial dislocation, lateral displacement, intrusive dislocation, complete dislocation, etc. The training model for teaching dental trauma is designed for teaching dental trauma. At the same time, different half-pairs of maxillary molds can be detachably spliced ​​together to form a maxillary mold, thereby realizing a variety of maxillary mold combinations and simulating different dental trauma conditions.

[0037] 2. The dental teaching simulation mold provided by the present invention has a broken tooth model whose cut position is connected to a magnet through the cross section, and is magnetically fixed. The above structure can be quickly disassembled and assembled to simulate tooth fracture.

[0038] 3. In the dental teaching simulation mold provided by the present invention, the anterior teeth positioning member is a positioning screw; and a threaded hole adapted to the positioning screw is provided on the anterior teeth alveolar socket;

[0039] In the fixed position, the positioning screw is tightened and abuts against the traumatic tooth model, and the traumatic tooth model does not loosen; in the loosened position, the positioning screw is loosened and away from the traumatic tooth model, and the traumatic tooth model loosens.

[0040] In the present invention, the front teeth positioning member is a positioning screw. The positioning screw can effectively abut and fix the traumatic tooth model, thereby controlling whether the traumatic tooth model is loose. BRIEF DESCRIPTION OF THE DRAWINGS

Fig.11 The above-mentioned embodiment of the present invention is shown Fig.10 Schematic diagram of the normal position of the injured tooth model after reduction. Fig.12 The diagram shows the positions of the two ends of the gingival edge of the bone plate in the embodiment of the present invention and the position of the connecting shaft 6 connected to the alveolar bone plates on both sides. The labial bone plate 1-1-1 of the right maxillary bone plate fracture model 1-a is in a separated state, and the two ends of the gingival edge of the bone plate are connected to the alveolar bone plates on both sides by connecting shafts 6; and the square edge of the bone plate 1-1-1 is embedded with a magnet 3-3, and after the separated bone plate is reset, the corresponding alveolar process is placed in the magnet 3-4, and is adsorbed and positioned with the bone plate magnet.

[0071] The usage of this model is as follows:

[0072] 1. Simulation of lateral displacement injury type: The right maxillary model uses the right maxillary bone plate fracture model 1-a, and the left maxillary model uses the left maxillary alveolar socket enlargement model 1-b or the left maxillary complete model 1-d according to the need of simulating injury. The complete tooth model 2-1-1 of the right upper central incisor is placed in the alveolar socket 1-1, and the tooth root is labially dislocated from the alveolar socket, and the root apex magnet 3-2 is attracted to the magnet 3-4, and at the same time, the end of the labial bone plate 1-1-1 is separated from the alveolar process, simulating the injury state of the lateral displacement of the tooth and the bone plate. During the resetting operation, the tooth root is pressed back to the alveolar socket, and the root apex magnet 3-2 is attracted to the magnet 3-1 at the bottom of the alveolar socket; at the same time, the labial bone plate 1-1-1 is relocated, and the magnet 3-3 at the end of the bone plate is attracted to the magnet 3-4, showing the position of the tooth and the state of the bone plate after resetting.

[0073] 2. Simulation of partial dislocation injury type: The right maxillary model uses the right maxillary bone plate fracture model 1-a or the right maxillary complete model 1-c, and the right upper lateral incisor 2-3-1 is placed in the alveolar socket, and the root labial magnet 3-6 is attracted to the alveolar socket labial edge magnet 3-7. At this time, the tooth position simulates a partial dislocation injury. During the operation practice, the right upper lateral incisor in this position is reset to the alveolar socket, and the root tip magnet 3-2 is attracted to the alveolar socket 2-3 bottom magnet 3-1 to simulate the normal position after reset.

[0074] 3. According to the type of simulated trauma, different half-maxillary models are matched and combined into a complete maxillary dental trauma model through the maxillary magnetic suction device 5. Match according to whether there is damage to the alveolar socket, such as lateral displacement and intrusion. For example: if there is lateral displacement injury and intrusion injury, the right maxillary bone plate fracture model 1-a + left maxillary alveolar socket enlargement model 1-b are combined; if there is lateral displacement injury but no intrusion injury, the right maxillary bone plate fracture model 1-a + left maxillary complete model 1-d are combined; if there is no lateral displacement but intrusion injury, the right maxillary complete model 1-c + left maxillary alveolar socket enlargement model 1-b are combined; if there is no lateral displacement and no intrusion injury, the right maxillary complete model 1-c and left maxillary complete model 1-d are combined.

[0075] 4. In this model, there is a gap of about 0.2mm to 0.3mm between the right maxillary bone plate fracture model 1-a, the left maxillary alveolar socket enlargement model 1-b, the right maxillary complete model 1-c and the left maxillary complete model 1-d. Therefore, after the tooth root is completely placed in the alveolar socket, the apex magnet 3-2 and the alveolar socket bottom magnet 3-1 are adsorbed and fixed, and the tooth model is in a loose state, simulating the looseness after periodontal tissue damage. When the tooth needs to simulate the damage without periodontal tissue damage and looseness, for example, simple tooth body or pulp tissue damage, the anterior tooth positioning piece 4 on the palatal side of the alveolar socket, that is, the screw device, can be tightened; if the looseness after periodontal tissue damage needs to be simulated, the anterior tooth positioning piece 4, that is, the screw device, can be loosened.

[0076] If it is necessary to simulate a certain tooth or pulp tissue damage, the complete tooth model in the corresponding alveolar socket can be replaced with a broken tooth model. For example, to simulate crown fracture and pulp exposure, the original upper left central incisor complete tooth model 2-2-1 in the upper left central incisor alveolar socket 1-2 is replaced with the upper left central incisor "crown fracture and pulp exposure" model 2-2-2.

[0077] Of course, this embodiment does not specifically limit the specific connection method of the adjacent left and right half maxillary models. In other embodiments, the adjacent left and right half maxillary models are spliced ​​into a complete maxillary dental trauma model through a snap-on structure.

[0078] Of course, the present embodiment does not specifically limit the specific structure of the anterior teeth positioning member 4. In other embodiments, the anterior teeth positioning member 4 may also be a telescopic push rod; the anterior teeth alveolar socket is provided with a through hole adapted to the positioning screw, and the through hole and the telescopic push rod are interference fit. In the fixed position, the telescopic push rod abuts against the traumatic tooth model, and the traumatic tooth model does not loosen; in the loosened position, the telescopic push rod is away from the traumatic tooth model, and the traumatic tooth model loosens.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
