Description

Removable denture device

This creation relates to a denture device, and more particularly to a detachable denture device that prevents loosening of chewing food.

In general, the detachable denture device can be roughly divided into an inner crown and an outer crown, and a combination thereof becomes a denture, and the denture is fixed to the patient's gum bed. In addition, the outer crown can be removed to remove food residue if necessary. For the device for fixing the denture, please refer to the following instructions.

Referring to Figure 1, it is a schematic view of a conventional denture device. The denture device comprises an inner crown A and an outer crown B. The inner crown A is fixed on the gum bed of the patient, and a surface of the inner crown A is provided with a bump 11. The outer crown B is used to set the inner crown A, and the inner top of the outer crown B is provided with a fastening component 13. When the outer crown B is sleeved with the inner crown A, the fastening component 13 can buckle the bump 11.

Referring to Fig. 2, it is a cross-sectional view of the fastening member 13 of the conventional denture device holding the projection 11. In this way, the relative position between the inner crown A and the outer crown B can be fixed. However, the fastening element 13 is made of an elastic material, and after a period of time, the elastic force will be weakened, so that the outer crown B may be shaken or loosened, so that the patient may feel inconvenience or discomfort when chewing food. .

Therefore, how to improve the stability of the relative position between the inner crown A and the outer crown B, and let the patient obtain a better quality denture device to maintain the comfort of daily life diet is the most important thing for the creative to solve the inconvenience. purpose.

The present invention relates to a detachable denture device that prevents loosening of the outer crown due to chewing of food or when the elastic gripping force of the fastening component is weakened.

To achieve the above object, the present invention provides a detachable denture device comprising an inner crown, a bump, an outer crown and a resilient cap buckle. The inner crown is fixed to a gum bed, and the outer surface of the inner crown is provided with a first groove and a second groove, and the first groove and the second groove respectively have a first end fastening And a second end fastening portion. The bump is disposed on the upper surface of the inner crown. The inner crown is configured to sleeve the inner crown, and the inner side wall of the outer crown is provided with a first engaging component and a second engaging component. When the outer crown is sleeved with the inner crown, the first engaging component is The second engaging component is slid down along the first groove and the second groove to be guided to the first end fastening portion and the second end fastening portion, so that the first end buckle The joint portion and the second end engaging portion fasten the first engaging element and the second engaging element. The elastic cap is disposed on the inner side of one of the outer crowns, so that when the outer crown is sleeved on the inner crown, the protrusion is elastically wrapped to fix the relative position between the inner crown and the outer crown. .

After referring to the drawings and the embodiments described later, those skilled in the art can understand the other purposes of the present invention, as well as the technical means and implementations of the present invention.

The cross-section of the crown after the inner crown is set.

The present invention will be explained below by way of examples, however, the embodiments of the present invention are not intended to limit the creation of the present invention in any environment, application or manner as described in the embodiments. Therefore, the description of the embodiments is merely illustrative of the purpose of the present invention and is not intended to limit the present invention. It should be noted that in the following embodiments and drawings, elements that are not directly related to the present creation have been omitted and are not shown.

Please refer to Figure 3, which is an exploded view of the detachable denture device. The detachable denture device 3 includes an inner crown A, an outer crown B, a bump 31 and a resilient cap 33. The inner crown A is fixed on a real tooth T, and a surface of the inner crown A is provided with a first groove 3a and a second groove 3b. The first groove 3a and the second groove 3b are respectively connected to a first end engaging portion 4a and a second end engaging portion 4b, see Fig. 4. The fourth picture is a schematic diagram of the creation of the inner crown A after the creation of the outer crown B. The bump 31 is disposed on the upper surface of the inner crown A. The outer crown B is in the form of a inverted type for arranging the inner crown A, and the inner side wall of the inverted type is provided with a first engaging element 35a and a second engaging element 35b for the outer crown B to be sleeved. In the case of the crown A, the first engaging element 35a and the second engaging element 35b are slid down along the first groove 3a and the second groove 3b, respectively, and are guided to the first end engaging portion 4a and the second end buckle. The joint portion 4b is such that the first end engaging portion 4a and the second end engaging portion 4b are respectively fastened to the first engaging member 35a and the second engaging member 35b. It should be specially noted that, since the elastic cap 33 is disposed on the inner top of one of the outer crowns B, when the outer crown B is sleeved with the inner crown A, the bump 31 can be elastically covered to stabilize the inner crown A and the outer crown B. The relative position between.

In order to make those skilled in the art more aware of the implementation of the present invention, please refer to FIG. 5, which is a cross-sectional view of the outer crown B of the creation of the inner crown A. Here, only the following points need to be specifically stated.

The first, first engaging element 35a and the second engaging element 35b respectively have a first elastic engaging portion 35c and a second elastic engaging portion 35d. The first engaging element 35a and the second engaging element 35b are slid down along the first groove 3a and the second groove 3b to be guided to the first end engaging portion 4a and the second end engaging portion 4b until The first elastic engaging portion 35c and the second elastic engaging portion 35d respectively engage the first end engaging portion 4a and the second end engaging portion 4b to make the inner crown A of the entire denture device 3 and the outer crown B The location is more stable. The first engaging element 35a, the second engaging element 35b, the first elastic engaging portion 35c and the second elastic engaging portion 35d described above may be a material of a nickel-titanium storage alloy (NiTi memory metal) having elasticity. system.

The second elastic cap 33 has an accommodating space 37 for covering the bump 31, and the accommodating space 37 is substantially the same shape as the bump 31, so that the outer crown B can be better than the inner crown A. The effect of closeness and stability of its relative position.

Figure 6 is a cross-sectional view of the outer crown B after the creation of the inner crown A. In this way, the first engaging element 35a and the second engaging element 35b of the present invention are used to assist the elastic cap 33 to more stably maintain the relative position between the inner crown A and the outer crown B without causing the outer crown B to be elastic. Hat buckle 33 loses its elastic force and is loose, with a double fixing effect. Compared with the prior art, this creation has greatly improved the stability of the relative position between the inner crown A and the outer crown B, allowing the patient to obtain a better quality denture device to maintain the comfort of daily life diet, and the patient also It can be removed by yourself and cleaned to protect the real tooth T and avoid the problem of tooth decay again.
