Description

Technical Field

[0001] This utility model relates to the field of denture base technology, specifically an absorbent denture and its base. Background Technology

[0002] Prosthodontics, as a branch of dentistry, has always held a very important position in the field of oral medicine. Currently, the most common methods of complete denture restoration are implant-supported complete dentures and traditional complete dentures. The former has limitations in clinical application due to its high cost and difficulty in maintenance. Traditional complete dentures, on the other hand, suffer from insufficient adhesion, intraoral movement, and dislodgement, leading to the development of absorbent dentures. Absorbent dentures offer advantages such as relative affordability and good retention.

[0003] Traditional suction cup-type dentures achieve adhesion by deforming a suction cup protruding from the denture base surface, as shown in CN207837665U (a suction-functional denture) and CN217448066U (a novel removable denture base matching structure). Traditional suction cup-type dentures have the following drawbacks: 1. Existing suction cup structures easily affect the tightness of the fit between the denture base edge and the surrounding mucosal tissue; 2. The suction force during denture use is not ideal. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an absorbent denture and its base that facilitates close contact between the edge of the absorbent denture base and the surrounding mucosal tissue, and has better absorbency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an absorbent denture base, including a denture base body, a gingival groove on one side of the denture base body, an oral contact surface on the side surface of the denture base body where the gingival groove is located, and a pit on the side surface of the denture base body where the gingival groove is located to form an absorbent cavity.

[0006] Furthermore, the bottom of the adsorption cavity is provided with a protrusion.

[0007] Furthermore, the protrusion is spherical.

[0008] Furthermore, the height of the protrusion is greater than its spherical radius, thereby forming an indentation between the protrusion and the bottom of the adsorption cavity.

[0009] Furthermore, the adsorption cavity is a regular hexagon.

[0010] Furthermore, the diameter of the inscribed circle of the adsorption cavity is 1.6–3 mm.

[0011] Furthermore, the inner surface of the adsorption cavity is provided with a groove.

[0012] Furthermore, the groove is a hemispherical groove with a radius of 0.1 to 0.15 mm, and the grooves are spaced 0.15 mm apart along the direction of the adsorption cavity.

[0013] An absorbent denture, employing the aforementioned absorbent denture base.

[0014] The beneficial effects of this utility model are as follows: The adsorption denture and its base of this utility model have an adsorption cavity formed by a pit on the side surface (oral lining surface) of the denture base body where the gingival clasp is set. After the denture base is adsorbed onto the oral surface, the gap between the back of the denture base body and the oral surface is not easily changed, and the edge sealing effect is better. In the process of destroying the adsorption effect of the denture base, it is necessary to overcome the water molecule tension between the back of the denture base body and the oral surface and the negative pressure formed in the adsorption cavity due to the movement of oral soft tissue. Air is more difficult to enter the adsorption cavity. Therefore, its adsorption force is greater, the adsorption effect is better, the edge sealing effect is better, and the wearing experience is improved. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2As shown, the adsorbent denture 1 of this invention includes an adsorbent denture base and teeth 12. The adsorbent denture base includes a denture base body 11, with a gingival clasp 111 on one side. The surface of the denture base body 11 with the gingival clasp 111 forms an oral contact surface that fits snugly against the patient's oral cavity. The teeth 12 are mounted on the denture base body 11. The denture base body 11 is generally made of high-strength resin or metal. To ensure a tight fit between the edge of the adsorbent denture base and the surrounding mucosa, and to improve its adsorption properties, this invention provides recesses on the surface of the denture base body 11 with the gingival clasp 111 to form adsorption cavities 112. There are usually multiple recesses spaced apart. The specific number and spacing of the recesses can be determined through actual experiments. It is understood that the adsorption cavities 112 are generally positioned along the normal direction of the surface of the denture base body 11 with the gingival clasp 111.

[0022] When dentures are worn, the side surface of the denture base 11 with the gingival clasp 111 facing the upper or lower surface of the oral cavity. For example, for upper dentures, the side surface of the denture base 11 with the gingival clasp 111 facing the upper surface of the oral cavity; for lower dentures, the side surface of the denture base 11 with the gingival clasp 111 facing the lower surface of the oral cavity. Figure 1 This is an upper dental prosthesis. Typically, the side of the denture base body 11 where the gingival clasp 111 is located is called the back side, and the other side is called the front side. The specific shape of the back side of the denture base body 11 is set according to the corresponding surface shape of each patient's oral cavity.

[0023] Because oral soft tissue is deformable, when wearing the denture of this invention, after it is installed in the oral cavity, pressing the front of the denture base 11 against the front of the denture base body 11 will cause the back of the denture base body 11 to fit against the oral cavity surface, allowing the oral soft tissue to enter the suction cavity 112, sealing the suction cavity 112 and creating a certain negative pressure. In addition, since there are inevitably saliva water molecules between the back of the denture base body 11 and the oral cavity surface, the surface tension of the water molecules can adhere and fix the denture base to the oral cavity.

[0024] Traditional dentures using suction cup structures rely primarily on the deformation of the protruding suction cups to generate negative pressure. After the denture base is installed, a large gap easily forms between the back of the denture base 11 and the oral cavity surface. This causes the tension of water molecules between the back of the denture base 11 and the oral cavity surface to be broken during the adsorption process, allowing air to easily enter the adsorption cavity 112, resulting in a less than ideal adsorption effect. In contrast, the adsorption cavity 112 of this invention is formed by a recess on the back surface of the denture base. After the denture base is adsorbed onto the oral cavity surface, the gap between the back of the denture base 11 and the oral cavity surface does not easily change. During the process of breaking the adsorption of the denture base, it is necessary to simultaneously overcome the tension of water molecules between the back of the denture base and the oral cavity surface, as well as the negative pressure formed in the adsorption cavity 112 due to the movement of oral soft tissue. Air is even less likely to enter the adsorption cavity 112, resulting in a stronger adsorption force and a better adsorption effect. In addition, because this invention makes it less likely for the gap between the back of the denture base 11 and the oral cavity surface to change, it also allows the back and edges of the absorbent denture base to fit more closely with the surrounding mucosal tissue, resulting in a better edge sealing effect.

[0025] like Figure 2 As shown, the bottom of the adsorption cavity 112 is further provided with a protrusion 113. The protrusion increases the contact area between the adsorption cavity 112 and the oral soft tissue, which can increase the water molecule tension between the inner wall of the adsorption cavity 112 and the oral soft tissue, and also helps to improve the adsorption effect of the denture.

[0026] The protrusion 113 can be of various shapes, such as triangle, column, square, sphere, etc. Relatively speaking, when the protrusion 113 is spherical, it makes better use of its surface to contact the soft tissues of the oral cavity.

[0027] The height of protrusion 113 can be less than or equal to or greater than the radius of its sphere. In this utility model, as in 2 and Figure 3 As shown, preferably, the height of the protrusion 113 is greater than its spherical radius, thereby forming an inverted recess 114 between the protrusion 113 and the bottom of the adsorption cavity 112. The inverted recess 114 facilitates saliva retention and the generation of negative pressure, both of which contribute to enhanced adsorption force.

[0028] The adsorption cavity 112 can be circular, triangular, square, or a regular polygon, etc. For example... Figure 4 As shown in the embodiment of this utility model, the adsorption cavity 112 is a regular hexagon. The regular hexagonal shape of the adsorption cavity 112 makes its structure more stable.

[0029] When the adsorption cavity 112 is a regular hexagon, the diameter of the inscribed circle of the adsorption cavity 112 is preferably 1.6 to 3 mm. When the diameter of the inscribed circle of the adsorption cavity 112 is 1.6 to 3 mm, it is convenient for molding during manufacturing and also helps to ensure the strength of the base.

[0030] like Figure 2 As shown, the inner side of the adsorption cavity 112 is provided with a groove 115. The groove 115 can increase the contact area between the adsorption cavity 112 and the oral soft tissue, facilitate the retention of saliva, facilitate the formation of water molecule tension between the side wall of the adsorption cavity 112 and the oral soft tissue, and also help improve the adsorption force of the denture.

[0031] The groove 115 can be of various shapes, such as square or circular. In this embodiment of the invention, the groove 115 is a hemispherical groove. The hemispherical shape of the groove 115 also facilitates saliva retention. When the groove 115 is hemispherical, in this embodiment of the invention, when the spacing of the grooves 115 along the direction of the adsorption cavity 112 is 0.15 mm, the radius of the groove 115 is 0.1–0.15 mm.

[0032] For patients with less oral mucus, structures such as protrusion 113 and groove 115 are more effective in improving the adhesion of dentures.
