Description

Technical Field

[0001] The present invention relates to an articulator, and particularly to a denture articulator and a using method thereof. Background Art

[0002] Tooth defects are inevitable. When tooth problems occur, timely repair is required. Many people choose dentures. Currently, when making dentures, most dentists first take impressions using denture tray impression materials, and then send the denture tray impressions to the factory for denture processing. After receiving the model, the factory needs to pour fluid gypsum into the opposing denture tray impression. After the fluid gypsum cools, the opposing gypsum dental model is taken out, and then the excess gypsum on the buccal side and lingual spurs of the opposing gypsum dental model is polished. Then, holes are drilled at the bottom to install a fixing nail set. A traditional fixing nail set is as Figure 1 shown. It includes a nail post 1a, a nail sleeve 2a, and a soft pad sleeve 3a. Workers need to insert the two nail feet 4a at the bottom of the nail post 1a into the nail sleeve 2a, and the part of the nail feet 4a extending out of the nail sleeve 2a is covered with the soft pad sleeve 3a. Then, the nail head 5a of the nail post 1a is inserted into the drilled opposing gypsum dental model. Then, a layer of gypsum separating agent is applied to the bottom of the opposing gypsum dental model. Then, fluid gypsum is poured into the base mold sleeve, and the opposing gypsum dental model equipped with the fixing nail set is inserted into the fluid gypsum, and the gypsum just covers the nail sleeve. Then, wait for the fluid gypsum in the base mold sleeve to cool. The nail sleeve 2a is fixed by the fluid gypsum in the base mold sleeve. Therefore, the opposing gypsum dental model with the nail post 1a and the opposing base equipped with the nail sleeve can be taken out. Then, the opposing base is ground and repaired. Then, the opposing gypsum dental model is installed back into the opposing base; the main jaw model denture tray also needs to repeat the above steps. Different from this, after grinding and repairing the main jaw base, the denture part of the main jaw gypsum dental model needs to be sawed off from the gypsum main jaw model using a saw blade, and then the neck margin line of the denture part is modified, and then it is installed back into the main jaw base together. Then, the main jaw base and the opposing base are connected through a connecting arm, and the occlusion relationship is detected. After determining that there is no problem, it is fixed with glue.

[0003] To sum up, the current overall process of making dentures is relatively cumbersome, and the base also needs to be filled and waited for cooling, which affects the production efficiency. A separating agent needs to be applied between the gypsum dental model and the base. In addition, the base is also made of fluid gypsum, with a high cost, and the weight of the gypsum is heavy, which increases the transportation cost. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a denture articulator and a using method thereof that save labor, materials, and transportation costs and improve production efficiency.

[0005] The technical solution adopted by the present invention is as follows: The present invention includes a denture articulator, which includes an opposing base frame and a main base frame. One end of the opposing base frame is provided with a connecting frame one, and one end of the main base frame is provided with a connecting frame two. The opposing base frame and the main base frame are connected by the cooperation of the connecting frame one and the connecting frame two. The surfaces of the opposing base frame and the main base frame are both provided with inner groove surfaces, and a number of implant pin holes are arrayed on the inner groove surfaces. The implant pin holes are polygonal groove holes with at least three sides, and PIN pins are adaptively installed on the implant pin holes.

[0006] Further, the implant pin holes are quadrilateral groove holes, and the aperture diameter of the quadrilateral groove holes gradually decreases from top to bottom. A digital relief mark is provided at one end of the implant pin hole and on the inner groove surface, and a limiting bump is provided at the other end of the implant pin hole and on the inner groove surface.

[0007] Further, connecting arms are provided at both ends of the connecting frame one and both ends of the connecting frame two. An opening snap ring is provided at the end of one of the connecting arms, and a column adapted to the opening snap ring is provided at the end of the other connecting arm.

[0008] Further, the PIN pin includes an integrally formed pin foot, a pin column, and a plug pin. The pin foot is adapted to the implant pin hole. The diameter of the pin column is greater than the aperture diameter of the implant pin hole. The plug pin is a rectangular plug pin, and chamfered surfaces are provided on all four sides of the rectangular plug pin, and a number of first bumps are provided on the chamfered surfaces.

[0009] Further, a marking slot hole group is provided at the front end of the inner groove surface.

[0010] Further, the opposing base frame and the connecting frame one are integrally injection molded from a transparent plastic material, and the main base frame and the connecting frame two are also integrally injection molded from a transparent plastic material, and the bottoms of the opposing base frame and the main base frame are both hollow.

[0011] Even further, the present invention further includes a method for using a denture articulator, which includes the following steps:

[0012] S1. Assemble the opposing base frame and the main base frame through the cooperation of the connecting frame one and the connecting frame two;

[0013] S2. Insert PIN pins into the corresponding implant pin holes on the opposing base frame according to the tooth positions marked by the doctor on the opposing model denture base of the patient;

[0014] S3. Fill the opposing model denture base of the patient with fluid gypsum and fix it on the opposing base frame, and let it stand for 8 - 12 minutes until the fluid gypsum on the opposing model denture base dries;

[0015] S4. Insert PIN pins into the corresponding nail planting slots of the main jaw base frame at the tooth positions on the main model denture base where the doctor needs to fabricate dentures for the patient.

[0016] S5. Fill the main jaw model denture base with fluid gypsum and fix it on the main jaw base frame, and let it stand for 8 - 12 minutes until the fluid gypsum on the main jaw model denture base dries out.

[0017] S6. Take out the gypsum main jaw model of the main jaw base frame and the gypsum opposing jaw model of the opposing jaw base frame.

[0018] S7. Remove the excess gypsum on the buccal side and lingual spurs of the gypsum main jaw model and the gypsum opposing jaw model through a grinding instrument.

[0019] S8. Saw open the denture part with PIN pins from the gypsum main jaw model through a sawing instrument.

[0020] S9. Modify the cervical margin line, fill in undercuts and air bubbles for the denture part with PIN pins in sequence, and finally apply a separating medium and a hardening agent to the denture part with PIN pins.

[0021] S10. Install the gypsum main jaw model back onto the main jaw base frame, install the gypsum opposing jaw model back onto the opposing jaw base frame, then rotate the opposing jaw base frame and the gypsum main jaw model to make the gypsum main jaw model and the gypsum opposing jaw model bite, and check the occlusion relationship.

[0022] Further, when filling the opposing jaw model denture base with fluid gypsum and fixing it on the opposing jaw base frame in step S3, the marked tooth positions need to be inserted into the PIN pins; when filling the patient's main jaw model denture base with fluid gypsum and fixing it on the main jaw base frame in step S5, the tooth positions of the denture need to be inserted into the PIN pins.

[0023] The beneficial effects of the present invention are as follows: 1. The integrally injection - molded opposing jaw base frame and main jaw base frame can save the materials for making the current gypsum base and the time for preparing the gypsum base; 2. The opposing jaw base frame and the main jaw base frame made of transparent plastic material have a much lower overall weight compared with the current gypsum base, effectively saving the transportation cost; 3. There are several nail planting slots on the opposing jaw base frame and the main jaw base frame, and each nail planting slot has a corresponding digital relief mark. When filling the denture impression with gypsum, the PIN pins can be inserted into the corresponding nail planting slots first, and then the filled denture impression gypsum can be directly inserted into the opposing jaw base frame and the main jaw base frame with PIN pins, thus reducing the process of punching holes and installing nails at the bottom of the denture impression gypsum, and the PIN pins are more convenient and faster to use compared with the current fixed nail group; 4. The opposing jaw base frame and the main jaw base frame made of transparent plastic material can separate the denture impression gypsum without the action of a gypsum release agent, effectively saving the material cost of the gypsum release agent and improving the preparation efficiency.

[0031] As Figures 2 to 7 shown, in this embodiment, the present invention includes a denture articulator, which includes an opposing jaw base frame 1 and a main jaw base frame 2. One end of the opposing jaw base frame 1 is provided with a connecting frame one 3, and one end of the main jaw base frame 2 is provided with a connecting frame two 4. The opposing jaw base frame 1 and the main jaw base frame 2 are connected by the cooperation of the connecting frame one 3 and the connecting frame two 4. The opposing jaw base frame 1 and the connecting frame one 3 are integrally injection-molded from a transparent plastic material, and the main jaw base frame 2 and the connecting frame two 4 are also integrally injection-molded from a transparent plastic material. Moreover, the bottoms of the opposing jaw base frame 1 and the main jaw base frame 2 are both hollow, and the surfaces of the opposing jaw base frame 1 and the main jaw base frame 2 are both provided with inner groove surfaces 5. The inner groove surfaces 5 can prevent subsequent plaster dental models from shifting and sliding on the opposing jaw base frame 1 and the main jaw base frame 2. A number of implant staple holes 6 are arrayed on the inner groove surfaces 5. The implant staple holes 6 are quadrilateral groove holes, and PIN nails 7 are adaptively installed on the implant staple holes 6. The opposing jaw base frame 1 and the main jaw base frame 2 can save the preparation time of the current fluid plaster for pouring the opposing plaster base frame and the main plaster base frame, and can effectively save the cost of plaster raw materials. Moreover, the opposing jaw base frame 1 and the main jaw base frame 2 made of transparent plastic material are much lighter in weight compared with the opposing plaster base frame and the main plaster base frame, which can effectively reduce the transportation cost. And the transparent plastic material will not adhere to the plaster, so the subsequent plaster dental model can be separated from the opposing jaw base frame 1 and the main jaw base frame 2 without applying a separating agent.

[0032] In this embodiment, the aperture of the quadrilateral slot gradually decreases from top to bottom. At one end of the pin-implanting slot 6 and on the inner groove surface 5, there is a digital relief mark 8. At the other end of the pin-implanting slot 6 and on the inner groove surface 5, there is a limiting bump 9 for limiting. The digital relief mark 8 facilitates the insertion of the PIN pin 7 into the corresponding quadrilateral slot.

[0033] In this embodiment, connecting arms 10 are provided at both ends of the first connecting frame 3 and both ends of the second connecting frame 4. At the end of one of the connecting arms 10, there is an open snap ring 11, and at the end of the other connecting arm 10, there is a stud 12 adapted to the open snap ring 11. This design can conveniently assemble the opposing jaw base frame 1 and the main jaw base frame 2.

[0034] In this embodiment, the PIN pin 7 includes an integrally formed pin foot 71, a pin post 72, and a plug pin 73. The pin foot 71 is adapted to the pin-implanting slot 6. The diameter of the pin post 72 is larger than the aperture of the pin-implanting slot 6. The plug pin 73 is a rectangular plug, and chamfered surfaces 74 are provided around the rectangular plug. A number of first bumps 75 are provided on the chamfered surfaces 74. This design can effectively fix the PIN pin 7 on the plaster dental model. The PIN pin 7 is more convenient and faster to use compared to the current fixed pin set and will not rotate in the pin-implanting slot 6.

[0035] In this embodiment, a marking slot hole group 13 is provided at the front end of the inner groove surface 5. The marking slot hole group 13 includes double-row and double-layer slot holes. This design facilitates the subsequent alignment of the front and rear ends of the plaster dental model.

[0036] In this embodiment, the present invention further includes a method for using a denture articulator, which includes the following steps:

[0037] S1. Assemble the opposing jaw base frame 1 and the main jaw base frame 2 through the cooperation of the first connecting frame 3 and the second connecting frame 4;

[0038] S2. Implant the PIN pin 7 into the corresponding pin-implanting slot 6 of the opposing jaw base frame 1 according to the tooth positions marked by the doctor on the opposing model denture base of the patient;

[0039] S3. Fill the opposing model denture base with fluid plaster and fix it on the opposing jaw base frame 1, and let it stand for 8 - 12 minutes until the fluid plaster on the opposing model denture base dries;

[0040] S4. According to the positions of the teeth where dentures need to be made on the master denture base of the patient, the doctor implants PIN pins 7 into the corresponding implant pin slots 6 of the master jaw framework 2. When the tooth positions of the dentures are not the frontmost or rearmost tooth positions, PIN pins 7 need to be implanted into the implant pin slots 6 at both the left and right ends of the tooth positions of the dentures. When the tooth positions of the dentures are the frontmost or rearmost tooth positions, 1 - 2 additional PIN pins 7 can be implanted in the master jaw framework 2 for fixation;

[0041] S5. Fill the master jaw denture base of the patient with fluid plaster and fix it on the master jaw framework 2, and let it stand for 8 - 12 minutes until the fluid plaster on the master jaw denture base dries;

[0042] S6. Remove the plaster master jaw model of the master jaw framework 2 and the plaster opposing jaw model of the opposing jaw framework 1;

[0043] S7. Use a grinding instrument to remove the excess plaster on the buccal side and lingual spurs of the plaster master jaw model and the plaster opposing jaw model;

[0044] S8. Use a sawing instrument to saw open the denture part with PIN pins 7 from the plaster master jaw model;

[0045] S9. Modify the cervical margin line, fill in undercuts and air bubbles for the denture part with PIN pins 7 in sequence, and finally apply a gap agent and a hardening agent to the denture part with PIN pins 7;

[0046] S10. Install the plaster master jaw model back onto the master jaw framework 2, install the plaster opposing jaw model back onto the opposing jaw framework 1, then rotate the opposing jaw framework 1 and the plaster master jaw model to make the plaster master jaw model and the plaster opposing jaw model bite, and check the occlusion relationship. If there is a deviation in the occlusion position, the connecting frame 1 - 3 can be burned off at high temperature. Since the connecting frame 1 - 3 is made of transparent plastic material and can deform at high temperature, after high - temperature treatment, the arc of the connecting frame 1 - 3 can be manually adjusted to make the occlusion relationship fit.

[0047] In this embodiment, when filling the opposing jaw denture base with fluid plaster and fixing it on the opposing jaw framework 1 in step S3, the marked tooth positions need to be inserted into the PIN pins 7; when filling the master jaw denture base of the patient with fluid plaster and fixing it on the master jaw framework 2 in step S5, the tooth positions of the dentures need to be inserted into the PIN pins 7.

[0048] The present invention is applied to the technical field of denture preparation.

[0049] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation to the meaning of the present invention. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
