Description

Denture structure

This creation is related to the technique of a denture structure, especially a denture structure that effectively cushions the bite force and allows the bite force to be evenly dispersed in the alveolar bone to improve the service life of the denture.

Conventional denture structures include implants, abutments, and dentures. The implant replaces the root into the alveolar bone, inserts the abutment into the implant, and finally places the denture on the abutment.

Although such a structure can be tightly combined with the alveolar bone, when the food is chewed, its force directly acts on the alveolar bone, and the chewing force is larger and the use period is longer than that of other dentures (for example, a bridge). However, the mechanical structure is still inferior to the real tooth, and the structure of the real tooth is shown in Fig. 1.

Fig. 1 is a schematic view showing the structure of a real tooth, as shown in the figure: the teeth of the real tooth 1 contain nerves, blood vessels and tissue fluid in the cavity 11. Moisture and nutrients in the tissue fluid can enter the dentinal tubules in the dentin, moisturizing the teeth to maintain activity and toughness. The periodontal ligament 12 is located between the root of the tooth and the alveolar bone. The periodontal ligament 12 is a highly elastic connective tissue fiber that surrounds the cementum of the root and is connected to the gums and alveolar bone to stabilize the teeth. When the teeth bite into a hard object, they can pass through the periodontal ligament 12 is buffered to disperse the bite force evenly in the alveolar bone to avoid damage to the teeth and alveolar bone.

Therefore, how to create a denture structure can replace the function of the autogenous periodontal ligament, so that the denture can be more cushioned when biting into the hard object, and the prosthesis is easy to be broken, so as to prolong the service life of the denture, it will be actively exposed by the creative. Where.

The purpose of the present invention is to provide a denture structure, mainly providing a denture structure with an artificial periodontal ligament, the artificial periodontal ligament is placed on the connection surface of the denture and the abutment or the connection surface between the abutment and the implant, The cushioning force makes the dentures more cushioning and more suitable for human teeth.

In order to achieve the above purpose, the present invention provides a denture structure having an implant, a base and a denture from bottom to top, the implant is locked on the alveolar bone, and the bottom end of the abutment is placed on the implant. The denture is set at the top of the abutment and covers the abutment. The feature is that a denture is provided at the center of the bottom of the denture, and an artificial periodontal ligament is disposed on the inner wall of the recess. When the denture sleeve is set at the top of the abutment The artificial periodontal ligament is located just at the connection surface of the denture and the abutment for buffering the bite force.

In order to achieve the above purpose, the present invention further provides a denture structure, which has an implant, a base and a denture from bottom to top, the implant is locked on the alveolar bone, and the bottom end of the abutment is placed on the implant. The denture is set at the top of the abutment and covers the abutment. The feature is that an artificial periodontal ligament is arranged around the bottom of the abutment. The artificial periodontal ligament is placed when the bottom end of the abutment is placed on the implant. Just on the abutment The connection surface with the implant for cushioning the bite force.

In a preferred embodiment, the artificial periodontal ligament is constructed of a polyvinyl ethyl ketone structure.

The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and effects of the present invention from the disclosure herein.

The embodiments of the present invention are described below with reference to the drawings. It should be noted that the following drawings are simplified schematic diagrams, and only the basic concept of the creation is illustrated in a schematic manner, and only the structure related to the creation is illustrated in the drawings. Rather than drawing the number, shape, and size of components in actual implementation, the type of each component in actual implementation, The quantity and proportion are not limited to the illustrations, and can be changed according to the actual design needs.

Please refer to FIG. 2 and FIG. 3 , which are schematic exploded view of the cross-sectional structure of the first preferred embodiment of the artificial denture structure and a schematic structural view of the cross-sectional structure. As shown in the figure, the denture structure 2 of the present invention has an implant 21, a base 22 and a denture 23 from bottom to top, the implant 21 is locked on the alveolar bone, and the bottom end of the base 22 is placed at the setting position. On the body 21, the denture 23 is set at the top end of the base 22 and covers the base 22.

Wherein, the center of the bottom of the denture 23 is provided with a recess 231. The inner wall surface of the recess 231 is provided with an artificial periodontal ligament 20. When the denture sleeve 23 is set at the top end of the base 22, the artificial periodontal ligament 20 is located just at the denture 23 and the base. The connecting surface of the table 22 is for buffering the biting force.

In the first preferred embodiment, the artificial periodontal ligament 20 is preferably constructed of a polyvinyl ethyl ketone structure.

With the above structure, the artificial periodontal ligament 23 can replace the autogenous periodontal ligament function. A structure in which both the denture 23 and the base 22 are rigid has a cushioned elastic structure. In order to increase the cushioning force and avoid the breakage of the denture when it bites into a hard object, the service life of the denture is prolonged.

Referring to FIG. 4 and FIG. 5, it is a schematic exploded view of the cross-sectional structure and a schematic view of the cross-sectional structure of the second preferred embodiment of the artificial denture structure. As shown in the figure, in the second embodiment, the denture structure 2 also has an implant 21, a base 22 and a denture 23 from bottom to top. The implant 21 is locked on the alveolar bone, and the bottom end of the base 22 is worn. Assume Positioned on the implant 21, the denture 23 is set at the top end of the base 22 and covers the base 22.

The difference from the first embodiment is that the artificial periodontal ligament 20 is disposed around the bottom of the base 22, and when the bottom end of the base 22 is placed on the implant 21, the artificial periodontal ligament 20 is located just on the base 22 The connection surface with the implant 21 is used for buffering the bite force.

In the second preferred embodiment, the artificial periodontal ligament 20 is preferably constructed of a polyvinyl ethyl ketone structure. With the above structure, the artificial periodontal ligament 23 can also be substituted for the autogenous periodontal ligament function. A structure in which both the abutment 22 and the implant 21 are rigid has a cushioned elastic structure. In order to increase the cushioning force and avoid the breakage of the denture when it bites into a hard object, the service life of the denture is prolonged.

Compared with the prior art, the artificial denture structure of the present invention mainly has an artificial periodontal ligament in the denture, so that the denture and the abutment have a buffering force to disperse the bite force and prevent the denture from being excessively broken and broken. In addition, artificial periodontal ligaments can be placed around the abutment to provide a cushioning force between the abutment and the implant, which can also disperse the bite force and prevent the denture from being excessively broken and broken, so as to improve the practicality of the denture and prolong the use of the denture. life.
