Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a denture that prevents loosening. Background Art

[0002] Dentures, commonly known as "false teeth," are a general term for restorations made after the loss of individual or all teeth in the oral cavity. Dentures include dental implants, which consist of the implant, abutment, and crown. During treatment, the implant, made of artificial materials, is first inserted into the alveolar bone at the site of the missing tooth, then the abutment is installed, and finally the crown is attached. Dental implants have advantages such as not damaging adjacent teeth, strong retention and stability, ease of replacement, effective prevention of alveolar bone atrophy after tooth loss, maximizing the restoration of chewing function, and facilitating oral hygiene.

[0003] In existing denture fixation techniques, the most common method of fixing the abutment to the crown is adhesive fixation. However, this method has certain drawbacks. Adhesive fixation is susceptible to the effects of the oral environment, leading to issues such as detachment. These problems not only affect the patient's experience but may also adversely impact their oral health. Utility Model Content

[0004] The purpose of this invention is to address the common problem mentioned in the background art that the common method of fixing the base and the crown is adhesive fixation. Adhesive fixation is easily affected by the oral environment, leading to detachment and other issues. These problems not only affect the patient's user experience but may also have adverse effects on the patient's oral health.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A type of denture designed to prevent loosening includes an implant, an abutment, and a crown. The abutment is fixed to the implant, and the crown is fixedly connected to the abutment by an adhesive. The crown is provided with a locking element that stabilizes and locks the abutment to prevent it from loosening.

[0007] Preferably, the implant has a threaded groove, and the abutment has a connecting groove that engages with the locking component. The connecting groove has a countersunk hole, and a screw is installed in the countersunk hole. The screw is connected to the connecting groove, and the screw can engage with the connecting groove in a threaded connection. The abutment is stably fixed to the implant by the screw.

[0008] Preferably, a connecting end is provided below the crown, and the locking member is provided on the connecting end. Several locking members are provided and arranged around the connecting end. By having multiple locking members, the locking members can better lock and connect the crown and the abutment together.

[0009] Preferably, the locking member includes a locking plate, which has a locking end to further improve the locking effect. The locking member enables the crown to be stably and fixedly connected to the abutment, so that the crown can still be stably and fixedly connected to the abutment even if the adhesive falls off, thus preventing it from easily loosening.

[0010] Preferably, the locking plate is bent inward at both ends so that the middle part protrudes outward to form an arc-shaped plate. The locking end is located on the outward side of the locking plate. When in use, the locking plate is an elastic plate that can deform appropriately. The outwardly deformed protruding part of the locking plate can make close contact with the locking groove.

[0011] Preferably, the connecting groove is provided with a locking groove 1 that cooperates with a plurality of locking plates. The locking groove 1 can lock and position with the locking plates, so that the crown can still be stably fixedly connected to the abutment even if the adhesive falls off.

[0012] Preferably, the first locking groove is provided with a second locking groove that mates with a plurality of locking ends. The locking ends are locked and positioned by the second locking groove, which can further improve the connection stability between the crown and the abutment and prevent the crown from loosening.

[0013] Preferably, the connecting end is provided with a plurality of grooves corresponding to the locking member, the locking plate is located in the groove, the two ends of the locking plate are bent inward and located in the groove, one end of which is connected to the connecting end. The groove allows the locking plate to move into the groove when it is pressed and deformed inward, making it easy to insert the connecting end into the connecting groove.

[0014] Preferably, the abutment has a protruding support end, and the crown has a support groove below it that cooperates with the support end, so that the crown can be stably fixed on the abutment through the support end.

[0015] Preferably, the crown has a reinforcing end protruding from its lower surface, and the abutment has a reinforcing groove that mates with the reinforcing end. When the crown is bonded to the abutment with adhesive, the reinforcing groove and the matching reinforcing end enable the crown and abutment to have not only planar bonding but also interlocking of concave and convex surfaces, thereby enhancing the connection stability between the two. Furthermore, the design of the groove and the protrusion increases the contact area between the crown and the abutment, which helps to increase the adhesion and stability of the adhesive between the two.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention, through the design of a locking component, enables the crown to be stably and fixedly connected to the abutment, ensuring that the crown remains stably fixed to the abutment even if the adhesive falls off, thus preventing it from easily loosening.

[0018] The reinforced ends and grooves add occlusion between the crown and abutment in addition to planar bonding, thereby enhancing the connection stability between the two. The groove and protrusion design increases the contact area between the crown and abutment, which helps to increase the adhesion and stability of the adhesive between them.

Example

[0032] Please see Figures 1-7 A type of anti-loosening denture includes an implant 1, an abutment 2, and a crown 4. The abutment 2 is fixed to the implant 1, and the crown 4 is fixedly connected to the abutment 2 by adhesive. The crown 4 is provided with a locking member 5 that stabilizes and locks the abutment 2 to prevent loosening. The implant 1 is provided with a threaded groove 11, and the abutment 2 is provided with a connecting groove 22 that engages with the locking member 5. The connecting groove 22 is provided with a countersunk hole 23, and a screw 3 is provided in the countersunk hole 23. The screw 3 is connected to the connecting groove 22 and can be threadedly engaged with the connecting groove 22. The abutment 2 is stably fixed to the implant 1 by the screw 3. A connecting end 41 is provided below the crown 4, and the locking member 5 is provided on the connecting end 41. Several locking members 5 are provided and arranged around the connecting end 41. By having multiple locking members 5, the locking members 5 can better lock the crown 4 and the abutment 2 together.

[0033] Furthermore, the locking component 5 includes a locking plate 51, on which a locking end 52 is provided to further improve the locking effect. The locking component 5 enables the crown 4 to be stably and fixedly connected to the abutment 2, so that the crown 4 can still be stably and fixedly connected to the abutment 2 even if the adhesive falls off, thus preventing it from easily loosening. The two ends of the locking plate 51 are bent inward so that the middle part protrudes outward as an arc-shaped plate. The locking end 52 is provided on the outward side of the locking plate 51. When in use, the locking plate 51 is an elastic plate that can be appropriately deformed. The outwardly deformed protruding part of the locking plate 51 can make close contact with the locking groove 24.

[0034] Furthermore, the connecting groove 22 is provided with a locking groove 1 24 that cooperates with several locking plates 51. The locking groove 1 24 can lock and position with the locking plates 51, so that the crown 4 can still be stably fixedly connected to the abutment 2 even if the adhesive falls off. The locking groove 1 24 is provided with a locking groove 25 that cooperates with several locking ends 52. The locking groove 25 locks and positions the locking ends 52, which can further improve the connection stability between the crown 4 and the abutment 2 and prevent the crown 4 from loosening.

[0035] It should be noted that the connecting end 41 is surrounded by several grooves 42 corresponding to the locking member 5. The locking plate 51 is located in the groove 42. The two ends of the locking plate 51 are bent inward and located in the groove 42. One end is connected to the connecting end 41. The groove 42 allows the locking plate 51 to move into the groove 42 when it is pressed and deformed inward, making it easy to insert the connecting end 41 into the connecting groove 22.

[0036] It should be added that the abutment 2 has a protruding support end 21, and the crown 4 has a support groove 43 below it that cooperates with the support end 21. The support end 21 enables the crown 4 to be stably fixed on the abutment 2. The inner side of the support end 21 has a chamfered surface, which allows the locking plate 51 to be pressed and deformed inward.

[0037] The crown 4 has a reinforcing end 44 protruding from its lower part, and the abutment 2 has a reinforcing groove 26 that mates with the reinforcing end 44. When the crown 4 is bonded to the abutment 2 with adhesive, the reinforcing groove 26 and the matching reinforcing end 44 enable the crown 4 and the abutment 2 to have not only planar bonding but also interlocking of concave and convex surfaces, thereby enhancing the connection stability between the two. Furthermore, the design of the groove and the protrusion increases the contact area between the crown 4 and the abutment 2, which helps to increase the adhesion and stability of the adhesive between the two.

[0038] In use, the implant 1 and abutment 2 are fixedly connected together by screws 3. When connecting the crown 4 to the abutment 2, a bonding agent is first applied to the abutment 2, then the crown 4 is placed on the abutment 2. The support end 21 is inserted into the support groove 43, and the connecting end 41 is inserted into the connecting groove 22. When the connecting end 41 is inserted into the connecting groove 22, the locking plate 51 is pressed inward by the beveled surface, causing the locking plate 51 to retract into the groove 42. Then, the crown 4 is pressed down until it is tightly attached to the abutment 2. The locking plate 51 is in the locking groove 24 and rebounds to engage and lock with the locking groove 24. The locking end 52 is in the locking groove 25, which can further lock and connect. Then, the adhesive between the abutment 2 and the crown 4 is cured to fix them together. Through the connection and cooperation between the locking plate 51 and the locking groove 24 and the locking end 52 and the locking groove 25, the crown 4 can still be stably fixed to the abutment 2 even if the adhesive falls off, preventing it from loosening easily.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
