Description

Technical Field

[0001] This utility model relates to the field of oral occlusion positioning technology, specifically an occlusion positioning device. Background Technology

[0002] Occlusion is the process by which the upper and lower dental arches change from one occlusal position to another during mandibular functional movements. Generally, before oral surgery such as dental implant restoration or orthodontic treatment, patients need to bite to take impressions of their teeth.

[0003] However, current methods for taking occlusal records are easily affected by factors such as muscle strength, cusp inclination, interocclusal height, and occlusal plane. Furthermore, current techniques are not perfect, are difficult for beginners to master, and patients often do not cooperate well. As a result, occlusal records often fail to meet clinical requirements, necessitating multiple recordings and leading to certain limitations in their use. Therefore, we propose an occlusal locator to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a bite positioner to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an occlusal locator, comprising a maxillary locating component, the maxillary locating component comprising a maxillary locating piece, a mandibular locating component disposed on one side of the maxillary locating piece, and the mandibular locating component comprising a mandibular locating piece, an adjusting component disposed on the end face of the maxillary locating piece near the mandibular locating piece, and the adjusting component comprising a mold piece fitted to the end face of the maxillary locating piece near the mandibular locating piece, and a fixing bolt passing through the interior of the mold piece to connect the maxillary locating component and the adjusting component, a positioning component connecting the adjusting component and the mandibular locating component, and the positioning component comprising a central positioning screw.

[0006] As a preferred technical solution of this utility model, the end face of the maxillary positioning piece near the lingual side of the teeth is arc-shaped, and the maxillary positioning component also includes a connecting block integrally fixed at the end of the maxillary positioning piece away from the lingual side of the teeth.

[0007] As a preferred technical solution of this utility model, the connecting block has a first connecting hole inside, and the inner surface of the first connecting hole is provided with a concave thread structure that cooperates with the fixing bolt.

[0008] As a preferred embodiment of this utility model, the connecting block is a semi-circular shape with a radius of 4mm, and the fixing bolt is threadedly connected to the connecting block through the first connecting hole.

[0009] As a preferred technical solution of this utility model, the mandibular positioning piece has an arc-shaped end face near the lingual side of the teeth, and the mandibular positioning component further includes a second connecting hole opened inside the mandibular positioning piece, and the inner surface of the second connecting hole is provided with a concave thread structure that cooperates with the central positioning screw.

[0010] As a preferred embodiment of the present invention, the adjustment component further includes a groove formed on the end face of the mold plate away from the maxillary positioning plate, and a connecting groove that penetrates the interior of the mold plate is formed inside the groove. The adjustment component also includes a positioning hole formed inside the mold plate.

[0011] As a preferred embodiment of this utility model, the head of the fixing bolt is located inside the groove, and the shank of the fixing bolt is slidably connected to the interior of the mold plate through the connecting groove.

[0012] As a preferred embodiment of this utility model, the positioning component further includes a connecting rod integrally fixedly connected to one end of the central positioning screw, and the connecting rod is rotatably connected to the mold plate through a positioning hole.

[0013] As a preferred embodiment of this utility model, the outer surface of the central positioning screw is configured with an M5 thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the bite positioner effectively solves the problems of muscle deprogramming, poor induction of cusp inclination, induction of maxillofacial deviation, and insufficient vertical distance between jaws. Even if the patient's bite is deviated and the upper and lower jaws are deviated, the axial mid-jaw position can be found and fixed. When taking bite impressions, the bite positioner can better assist the doctor in positioning and facilitate the recording of impression data.

[0015] 1. The rod of the fixing bolt is slidably connected to the inside of the occlusal mold through the connecting groove. When assembling this occlusal positioner, the connection position of the adjustment component relative to the maxillary positioning component is adjusted according to the position of the patient's maxillary and mandibular deviation. By rotating the fixing bolt, the head of the fixing bolt is pressed into the occlusal mold inside the groove, thus fixing the adjustment component and the maxillary positioning component. By adjusting the connection position of the fixing bolt and the occlusal mold during connection, the anterior-posterior position of the mandibular positioning component relative to the maxillary positioning component can be changed, thereby better adapting to the anterior-posterior deviation of the maxillary and mandibular positions of different patients. By rotating the connection between the positioning component and the adjustment component, the angular position deviation of the maxillary and mandibular positioning components can be determined. Even if the patient's occlusion is deviated and the position of the maxilla and mandible is deviated, the axial mid-maxillary position can be found.

[0016] 2. By rotating the central positioning screw, the central positioning screw is threaded to the mandibular positioning piece through the second connecting hole, and the connecting rod is inserted into the mold piece through the positioning hole. This allows the maxillary positioning component and the mandibular positioning component to be connected. After taking the impression, the height difference between the maxillary and mandibular positioning components can be used to record the height between the patient's upper and lower jaws. This effectively solves the problems of muscle deprogramming, poor induction of cusp inclination, maxillofacial deviation induction, and insufficient vertical distance between the jaws, which lead to difficulties in taking impressions.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an occlusal locator, including a maxillary locating component 100, the maxillary locating component 100 including a maxillary locating piece 101, a mandibular locating component 200 disposed on one side of the maxillary locating piece 101, and the mandibular locating component 200 including the mandibular locating piece 201, specifically as follows... Figure 1 , Figure 2 and Figure 4As shown, the maxillary positioning piece 101 has an arc-shaped end face near the lingual side of the teeth, and the mandibular positioning piece 201 has an arc-shaped end face near the lingual side of the teeth. Since there is a difference in the shape of the upper and lower teeth, the maxillary positioning piece 101 and the mandibular positioning piece 201 can be matched with the arrangement shape of the upper and lower teeth in the oral cavity by matching the lingual side of the teeth, respectively, so as to better fit the model.

[0024] The maxillary positioning component 100 also includes a connecting block 102 integrally fixed at the end of the maxillary positioning piece 101 away from the lingual side of the teeth. The connecting block 102 is a semi-circular shape with a radius of 4mm, and a first connecting hole 103 is provided inside the connecting block 102. An adjustment component 300 is provided on the end face of the maxillary positioning piece 101 near the mandibular positioning piece 201. The adjustment component 300 includes a mold piece 301 that fits against the end face of the maxillary positioning piece 101 near the mandibular positioning piece 201. A fixing bolt 4 is provided through the mold piece 301 to connect the maxillary positioning component 100 and the adjustment component 300. The fixing bolt 4 connects the maxillary positioning component 100 and the adjustment component 300.

[0025] Furthermore, the inner surface of the first connecting hole 103 is provided with a concave thread structure that mates with the fixing bolt 4. The adjusting assembly 300 also includes a groove 302 formed on the end face of the mold-forming piece 301 away from the maxillary positioning piece 101. The groove 302 has a connecting groove 303 that penetrates the interior of the mold-forming piece 301. Figure 1 and Figure 3 As shown, since the head of the fixing bolt 4 is located inside the groove 302, by rotating the fixing bolt 4, the rod of the fixing bolt 4 is threadedly connected to the connecting block 102 through the first connecting hole 103. At the same time, the head of the fixing bolt 4 presses the mold plate 301 inside the groove 302, thus fixing the adjustment component 300 and the maxillary positioning component 100. Meanwhile, since the rod of the fixing bolt 4 is slidably connected to the inside of the mold plate 301 through the connecting groove 303, the connection position of the adjustment component 300 relative to the maxillary positioning component 100 can be adjusted according to the deviation position of the patient's upper and lower jaws, thereby adjusting the connection position of the mandibular positioning component 200 relative to the maxillary positioning component 100. By changing the front and back position of the mandibular positioning component 200 relative to the maxillary positioning component 100, it can better adapt to the front and back deviation of the patient's upper and lower jaws.

[0026] Specific examples Figure 1 and Figure 4As shown, a positioning component 500 is connected between the adjustment component 300 and the mandibular positioning component 200. The positioning component 500 includes a central positioning screw 501. The outer surface of the central positioning screw 501 is set with an M5 thread. The mandibular positioning component 200 also includes a second connecting hole 202 opened inside the mandibular positioning piece 201. The inner surface of the second connecting hole 202 is provided with a concave thread structure that cooperates with the central positioning screw 501. The central positioning screw 501 is threadedly connected to the mandibular positioning piece 201 through the second connecting hole 202, so that the mandibular positioning component 200 can be connected, so that the mandibular positioning piece 201 is located below the maxillary positioning piece 101, and the maxillary positioning piece 101 and the mandibular positioning piece 201 are set parallel to each other.

[0027] Furthermore, the adjusting assembly 300 also includes a positioning hole 304 formed inside the mold plate 301, and the positioning assembly 500 also includes a connecting rod 502 integrally fixedly connected to one end of the central positioning screw 501, combined with... Figure 1 , Figure 3 and Figure 4 As shown, since the connecting rod 502 is rotatably connected to the mold plate 301 through the positioning hole 304, the positioning component 500 can rotate relative to the maxillary positioning component 100 and the adjustment component 300, thereby causing the mandibular positioning plate 201 to rotate relative to the maxillary positioning plate 101. This allows the mandibular positioning plate 201 and the maxillary positioning plate 101 to deviate at an angle, thus better aligning the bite deviation of the patient's upper and lower jaws.

[0028] The working principle of this utility model is as follows: When using this occlusal positioner, firstly, a plaster model is poured into the patient's oral cavity, and a standard impression of the teeth is taken. A separating agent is then applied to the lingual and occlusal surfaces of the plaster model, specifically as follows... Figure 1 As shown, since the rod of the fixing bolt 4 is slidably connected to the inside of the occlusal mold plate 301 through the connecting groove 303, the connection position of the adjusting component 300 relative to the maxillary positioning component 100 can be adjusted according to the deviation position of the patient's upper and lower jaws. By rotating the fixing bolt 4, the head of the fixing bolt 4 is pressed into the occlusal mold plate 301 inside the groove 302, and the adjusting component 300 and the maxillary positioning component 100 can be fixedly connected. By adjusting the connection position of the fixing bolt 4 and the occlusal mold plate 301 during connection, the front and back position of the mandibular positioning component 200 relative to the maxillary positioning component 100 can be changed, so as to better adapt to the front and back position deviation of the upper and lower jaws of different patients. The occlusal locator is fixed by wax pillars to keep the maxillary positioning component 100 and the mandibular positioning component 200 parallel.

[0029] Furthermore, the occlusal locator is placed in the patient's oral cavity with the curved surfaces of the maxillary locator 101 and mandibular locator 201 facing the lingual surfaces of the teeth. The occlusal locator is then connected to a plaster model using self-curing resin to fix the connection between the occlusal locator and the plaster model. After the self-curing resin solidifies, the plaster model and the occlusal locator are removed from the oral cavity. The distance between the maxillary locator 100 and the mandibular locator 200 can be determined by the connection height between the locating component 500 and the mandibular locating component 200, thereby determining the height difference between the maxilla and mandible. The front-to-back position of the connection between the fixing bolt 4 and the adjusting component 300, as well as the rotation angle of the connection between the locating component 500 and the adjusting component 300, can be determined by the front-to-back position and angular position deviation of the maxillary locating component 100 and the mandibular locating component 200. An intraoral occlusal record is taken of the occlusal locator, and the occlusal record is fixed in place by silicone rubber and transferred to the articulator.
