Description

Technical Field

[0001] This application relates to the medical field, and in particular to overlay denture removal and insertion devices. Background Technology

[0002] Overdentures are a special type of removable denture whose base covers and supports treated tooth roots or crowns. This type of restoration is particularly suitable for patients with missing teeth, few remaining teeth, and poor periodontal condition of the abutment teeth. Overdentures preserve natural teeth or roots, thereby reducing alveolar bone resorption, enhancing denture support, retention, and stability, and improving patients' chewing efficiency and oral health.

[0003] However, in clinical practice, the process of removing and inserting overdentures often presents some challenges. Due to the special nature of overdentures, the denture base and abutment teeth are usually connected by a precise attachment device, which makes the process relatively complicated. In particular, elderly patients or patients with poor fine motor skills may have some difficulty removing and inserting overdentures on their own. Utility Model Content

[0004] To ensure that both the denture and the oral cavity are kept clean and hygienic, this application provides a denture removal and insertion device.

[0005] The overlay denture removal and insertion device provided in this application adopts the following technical solution:

[0006] It includes a first support connected to the outside of the connector, and a second support integrally formed on the outside of the connector. The first support has a first strip for putting on and taking off, and the second support has a second strip for putting on and taking off.

[0007] By adopting the above technical solution, the connector can be removed from the oral cavity by removing the first and second removal strips after the elderly patient has eaten. This allows for timely rinsing and covering of the denture after meals, cleaning the oral cavity and ensuring that both the denture and the oral cavity are in a clean and hygienic condition. This is conducive to the long-term stable use of the denture and a clean and hygienic oral environment.

[0008] Preferably, the inner side of the connector is provided with an integrally formed first base, which is located near the first support.

[0009] By adopting the above technical solution, the adsorption force, friction force and constraint reaction force between the first base and the oral mucosa can help fix the denture in the oral cavity and prevent it from falling out or loosening. The first base can resist lateral forces and maintain the stability of the denture in the oral cavity. This stability is related to the height and fullness of the alveolar bone. The higher and fuller the alveolar bone, the better the stability.

[0010] Preferably, the outer side of the connector is provided with an integrally formed second base.

[0011] By adopting the above technical solution, the second base plate can easily support the artificial tooth, transmit and distribute the biting force generated during chewing, reduce the burden on the abutment tooth and mucosa, prevent damage from excessive pressure, and provide necessary support for the denture to ensure that the denture will not sink during use.

[0012] Preferably, a first adjacent support is provided on one side of the connector, and the first adjacent support is located near the first support.

[0013] By adopting the above technical solution, the chewing pressure borne by the denture can be transmitted to the natural teeth, preventing the denture from shifting towards the gum line due to force. The support force of the abutment teeth on the denture also plays a role through the first interproximal rest, ensuring that the denture remains stable under force. The presence of the first interproximal rest and the first rest enhances the stability of the denture and improves the patient's comfort.

[0014] Preferably, a retaining ring is provided on the other side of the connector, and the retaining ring is located between the second support and the rod-shaped retaining ring.

[0015] By adopting the above technical solutions, when there are gaps between the remaining teeth, placing clasps can effectively prevent food impaction and maintain oral hygiene. For abutment teeth that have no contact or poor contact with the opposing teeth due to tilting or low position, the occlusal contact relationship can be restored and chewing efficiency can be improved by enlarging the design of the clasps.

[0016] Preferably, a rod-shaped retaining ring is provided on the outer side of the connector.

[0017] By adopting the above technical solutions, it is possible to ensure that the dentures remain in the correct position in the oral cavity and prevent displacement.

[0018] Preferably, the second base is positioned near the rod-shaped retaining ring.

[0019] By adopting the above technical solutions, it is possible to ensure that the dentures remain in the correct position in the oral cavity and prevent them from falling out.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. With the first removal strip set on the outside of the first support and the second removal strip set on the outside of the second support, the connector can be removed from the oral cavity by the elderly patient after eating. This allows for timely rinsing of the denture after meals, cleaning the oral cavity, and ensuring that both the denture and the oral cavity are in a clean and hygienic condition. This is conducive to the long-term stable use of the denture and the cleanliness of the oral environment.

[0022] 2. The first and second removal strips make it easier for people to put the connector into their mouths after cleaning, which facilitates the removal and insertion operation. For elderly patients or patients with poor fine motor skills, it reduces the difficulty of removing and inserting the overdenture by themselves, making it more convenient to use and bringing convenience to elderly patients.

[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0028] This application discloses a denture removal and insertion device, including a first support 5 connected to the outside of a connector 1, a second support 7 integrally formed on the outside of the connector 1, a first removal and insertion strip 9 for removal and insertion provided on the outside of the first support 5, and a second removal and insertion strip 10 for removal and insertion provided on the outside of the second support 7.

[0029] By setting up a first removal strip 9 and a second removal strip 10, the connector 1 can be removed from the oral cavity by removing the first removal strip 9 and the second removal strip 10 after the elderly patient has eaten. This allows for timely rinsing and covering of the denture after meals, cleaning the oral cavity, and ensuring that both the denture and the oral cavity are in a clean and hygienic condition. This is conducive to the long-term stable use of the denture and a clean and hygienic oral environment.

[0030] Reference Figure 2 The inner side of the connector 1 is provided with an integrally formed first base 2, which is located near the first support 5.

[0031] By setting the first base 2, the adsorption force, friction force and constraint reaction force between the first base 2 and the oral mucosa help to fix the denture in the oral cavity and prevent it from falling out or loosening. The first base 2 can resist lateral forces and maintain the stability of the denture in the oral cavity. This stability is related to the height and fullness of the alveolar bone. The higher and fuller the alveolar bone, the better the stability.

[0032] Reference Figure 1 , Figure 2 An integrally formed second base 3 is provided on the outer side of the connector 1.

[0033] By setting a second base 3, the artificial tooth can be supported, and the biting force generated during chewing can be transmitted and distributed, reducing the burden on the abutment tooth and mucosa, preventing damage from excessive pressure. The second base 3 provides the necessary support for the denture, ensuring that the denture will not sink during use.

[0034] Reference Figure 1 , Figure 2 A first adjacent support 4 is provided on one side of the connector 1, and the first adjacent support 4 is located near the first support 5.

[0035] By setting the first interproximal rest 4 and the first interproximal rest 5, the chewing pressure borne by the denture can be transmitted to the natural teeth, preventing the denture from shifting towards the gum line due to force. The support force of the abutment teeth on the denture also plays a role through the first interproximal rest 4, ensuring that the denture remains stable under force. The presence of the first interproximal rest 4 and the first interproximal rest 5 enhances the stability of the denture and improves the patient's comfort.

[0036] Reference Figure 1 , Figure 2 On the other side of the connecting body 1, there is a retaining ring 6, which is located between the second support 7 and the rod-shaped retaining ring 8.

[0037] By setting up the clasp body 6, the second abutment 7, and the bar-shaped clasp 8, when there is a gap between the remaining teeth, placing the clasp body 6 can effectively prevent food impaction and maintain oral hygiene. For abutment teeth that have no contact or poor contact with the opposing teeth due to tilting or low position, the design of the enlarged clasp body 6 can restore the occlusal contact relationship and improve chewing efficiency.

[0038] Reference Figure 1 , Figure 2 A rod-shaped retaining ring 8 is provided on the outer side of the connecting body 1; the second base 3 is located near the rod-shaped retaining ring 8.

[0039] By setting a second base 3 and bar-shaped clasps 8, it is possible to ensure that the denture remains in the correct position in the oral cavity and prevent it from shifting or falling out.

[0040] The implementation principle of the denture removal and insertion device in this application embodiment is as follows: By setting the supports, the chewing pressure borne by the denture can be transmitted to the natural teeth, preventing the denture from shifting towards the gum line due to force. The support force of the abutment teeth on the denture also plays a role through the supports, ensuring that the denture remains stable under force. The first base 2 and the second base 3 support the artificial teeth, which can transmit and disperse the biting force generated during chewing, reduce the burden on the abutment teeth and mucosa, and prevent damage due to excessive pressure. The first base 2 and the second base 3 can provide necessary support for the denture, ensuring that the denture will not sink during use. The first removal strip 9 set on the outside of the first support 5 and the second removal strip 10 set on the outside of the second support 7 can be used to remove the connector 1 from the oral cavity after the elderly patient eats by removing the first removal strip 9 and the second removal strip 10. The denture can be rinsed in time after meals, cleaning the oral cavity and ensuring that both the denture and the oral cavity are in a clean and hygienic condition, which is conducive to the long-term stable use of the denture and a clean and hygienic oral environment.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
