Patent Application
20210128284
The present disclosure relates to a dental prosthesis that is worn in an oral cavity to replace a missing tooth, such as dentures, partial dentures, or a removable tooth protector.
Unless otherwise indicated in this specification, the technologies described in this section are not prior art to the claims of the present application, and the descriptions given in this section are not intended to admit that they correspond to prior art.
In general, persons have a total of 32 teeth including 16 teeth in the upper jaw and 16 teeth in the lower jaw. As the milk teeth generated during infancy enter a growth phase, they are replaced with permanent teeth, and oral activities are performed using the permanent teeth throughout their life.
In the case where one or more teeth are damaged due to oral disease, such as tooth decay, after the formation of permanent teeth, a missing tooth supplementing dental prosthesis is worn to supplement an insufficient chewing function.
A missing tooth supplementing dental prosthesis restores a function by supplementing a missing tooth with an artificial tooth (a denture) for the large parenchymal loss of the tooth, the deterioration of an oral function attributable to the mission of the tooth, or an abnormality in shape. Examples of a missing tooth supplementing dental prosthesis include dentures, partial dentures, and removable dental protectors.
As an example of a missing tooth supplementing dental prosthesis, in Korean Patent Application Publication No. 10-2015-0029117 (published on Mar. 18, 2015), there is disclosed a removable denture, including a coupling portion having a groove into which gums are inserted, a denture body having at least one artificial tooth arranged along the upper side of the coupling portion, and an elastic member embedded along the lower end of the coupling portion so that the coupling portion is elastically coupled to the gums.
Furthermore, in Korean Utility Model Registration No. 20-0183838 (published on Jun. 1, 2000), there is disclosed a partial denture fastening structure that in the construction of a partial denture including an artificial tooth and a denture base using metal or ceramic and synthetic resin for the appropriate restoration of a wide-tooth defect area,
The denture is formed at both side edges or one end so that the lower portion thereof is formed to penetrate and the upper portion thereof forms a channel-shaped recess to have a constant thickness, an adjacent tooth to which the denture is fastened has an insertion hole for mounting an inlay, including an insertion portion configured to have an approximate sideways “H” shape and to be fastened to the denture recess and a fastening portion formed by providing a plurality of protrusions fastened to the adjacent tooth with a constant angle in a downward direction, and the insertion hole fastens the denture while forming a constant downward inclination with respect to the horizontal surface of the tooth.
Furthermore, in Korean Patent No. 10-1682422 (published on Nov. 8, 2016), there is disclosed a removable tooth protector in which a cover body extends in an integrated form and is provided to cover the surfaces of the teeth from the molars to the front teeth, the cover body is configured to cover the occlusal and tongue surfaces for the molars and cover the tongue surfaces for the canine and the front teeth, when the occlusal surface of the tooth and the surface of the cover body in contact with the tongue surface is defined as the inner surface, the inner surface is formed to conform to the shapes of the occlusal and tongue surfaces, and the outer surface corresponding to the thickness from the inner surface is also formed to conform to the shapes of the occlusal and tongue surfaces, thereby enhancing wearing comfort and facilitating a chewing action, the cover body is provided with a detachable fastener configured to be attached to and detached from a tooth, and the detachable fastener is formed to extend to fit into the boundary between the tooth and the gums, and securely maintains an attached state when the removable tooth protector is worn on the tooth, thereby ultimately preventing food from clogging up when chewing the food and protecting a specific tooth.
In the case of the above-described conventional missing tooth supplementing dental prostheses, they are simply provided to a user in a state adjusted to be easily and beautifully detachable in the user's mouth, and it is configured to be detached as it is. However, during use, it cannot be adjusted according to the condition of the user's oral cavity, especially the condition of the gums. Therefore, when a user's gums are swollen, a problem arises in that wearing comfort is deteriorated.
The present invention is intended to provide a missing tooth supplementing dental prosthesis that may provide the best wearing comfort regardless of the condition of a user's gums as the height of an end of a missing tooth supplementing member is adjusted according to the condition of the user's gums.
Furthermore, technical problems of the present invention are not limited to the above-described technical problem, and it is obvious that another technical problem may be derived from the following description.
The present disclosure proposes a missing tooth supplementing dental prosthesis including: a prosthetic body configured to be detachably worn in the oral cavity of a user who has at least one missing tooth, and provided with a fastening portion that is formed in a portion corresponding to a missing tooth; and a missing tooth supplementing member configured to be height-adjustably coupled to the fastening portion of the prosthetic body, to be height-adjusted according to the condition of the user's gums, and to supplement the missing tooth as an embodiment.
According to a preferred feature of the present disclosure, the fastening portion may be formed on a supplementary member coupling element that is detachably coupled to the portion of the prosthetic body corresponding to the missing tooth.
The missing tooth supplementing dental prosthesis according to the present disclosure is advantageous in that as it is configured in a structure in which the missing tooth supplementing member is height-adjustably coupled to the fastening portion of the prosthetic body, the missing tooth supplementing dental prosthesis is worn in a user's oral cavity with the height of an end of the missing tooth supplementing member that comes into contact with the gums being adjusted according to the condition of the user's gums, thereby providing the best wearing comfort regardless of the condition of the user's gums.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.
The configuration, operation and operational effect of a missing tooth supplementing dental prosthesis according to a preferred embodiment will be described in detail below with reference to the accompanying drawings. For reference, in the following drawings, each component will be omitted or schematically illustrated for the purposes of convenience and clarity, and the size of each component does not reflect the actual size thereof. Furthermore, the same reference numerals refer to the same components throughout the specification, and reference numerals for the same components in the individual drawings will be omitted.
The missing tooth supplementing dental prosthesis 1 according to the embodiment of the present disclosure is detachably worn in the oral cavity of a user who has at least one missing tooth, and serves to restore functions by supplementing the missing tooth for the deterioration of an oral function and the abnormality of the shape of the oral cavity due to the mission of a tooth.
As shown in
In this case, the prosthetic body 10 is detachably worn in the oral cavity of a user who has at least one tooth, and functions to protect the tooth or supplement the function of the tooth.
The prosthetic body 10 has a cross-section in an inverted “U” shape as a whole to cover a teeth portion including a missing tooth and extend to the gums. Furthermore, although the prosthetic body 10 is shown in the form of a removable tooth protector, it may be formed as dentures or partial dentures.
