Description

Technical Field

[0001] The utility model relates to the field of oral medical treatment, in particular to a movable denture. Background Art

[0002] "Denture" means teeth that fulfill their "duty" for humans, commonly known as "false teeth". In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower jaws. Dentures are divided into removable and fixed. Fixed dentures cannot be removed and put on by the patient himself, while removable dentures can be easily removed and put on by the patient.

[0003] When most of the patient's natural teeth are damaged or missing, it is impossible to use removable dentures with brackets due to the small number of remaining natural teeth. The current conventional treatment method is to grind the remaining natural teeth so that full dentures can be worn later. However, the full dentures currently on the market are purely adsorption removable dentures, which only rely on the negative pressure formed between the base of the denture and the oral mucosa for adsorption and fixation. When the patient has problems such as gum atrophy, dry mouth, and excessive oral overflow, or when the full denture is used for a long time, resulting in insufficient or uneven adsorption area, the adsorption is greatly reduced, and the only fixing force of the removable denture is reduced, causing the full denture to fall off easily when the patient chews food in daily life, and even the removable denture will fall off by itself when it is static and there is no chewing action, which is inconvenient for patients to use in daily life.

[0004] Therefore, in order to solve the above-mentioned background technical problems, the utility model provides a removable denture. Utility Model Content

[0005] The utility model aims to provide a removable denture to solve the problems of poor installation stability and easy falling off of pure adsorption removable dentures in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a removable denture, including a base and a tooth body installed on the base, the base including a false tooth part and an original tooth mounting part, the lower part of the false tooth part is a concave wearing groove for fitting with the gums, the upper part of the false tooth part includes a plurality of tooth bodies fixedly installed on the base, and the original tooth mounting part is a single-layer structure for avoiding natural teeth; it also includes a fixing structure, the fixing structure includes a mounting bracket, the mounting bracket includes a main bracket and a limiting bracket, the main bracket is embedded in the base as a whole, one end of the limiting bracket is embedded in the base, and the other end is detachably connected and fixed to the natural teeth.

[0007] The beneficial effects are:

[0008] 1. In actual application, the utility model combines the bracket installation and adsorption installation, embeds the installation bracket into the base, utilizes the adsorption between the base and the oral cavity and the detachable fixation of the clamping ring of the limiting bracket and the natural tooth, realizes the double-layer stable installation of the removable denture, improves the stability of the installation, and effectively prevents the removable denture from falling off due to insufficient adsorption force during daily chewing.

[0009] 2. At the same time, unlike the existing full dentures on the market, which require the patient's remaining natural teeth to be polished during installation, the removable dentures in the utility model completely retain the patient's remaining natural teeth. Compared with full dentures, the patient's own natural teeth have stronger chewing ability. At the same time, the natural teeth also serve as fixed fulcrums to cooperate with the installation bracket to improve installation stability.

[0010] Preferably, as an improvement, the shape of the base is arc-shaped, and the shape of the base fits the gums.

[0011] The shape of the base is designed to be an arc that fits the gums, which can increase the adsorption area between the base and the oral cavity, improve the adsorption stability, and also ensure the comfort of the patient in wearing it.

[0012] Preferably, as an improvement, the embedding depth h of the main body support into the base is not less than 1 / 2 of the longitudinal depth H of the base.

[0013] The above arrangement is to ensure that the mounting bracket can effectively enhance the stability of the installation of the removable denture.

[0014] Preferably, as an improvement, the end of the limiting bracket close to the natural tooth is provided with a clamping ring for detachably connecting and fixing with the natural tooth.

[0015] The clasp is fixed on the natural tooth to achieve the coordination of the denture fixation through the bracket and adsorption fixation, further enhancing the stability of the denture installation.

[0016] Preferably, as an improvement, the clasp surrounds the middle of the natural tooth, and the surrounding size is not less than 1 / 2 of the circumference of the natural tooth.

[0017] The circumferential size of the clasp around the natural tooth is not less than 1 / 2 of the circumference of the natural tooth, which can effectively ensure the fixing effect of the clasp.

[0018] Preferably, as an improvement, the limiting bracket also includes a vertical clamping ring for buckling the molar.

[0019] In addition to the clasp to fix the molar in a circumferential manner, the vertical clasp is bent along the cusp of the molar and buckled into the pit and fissure of the molar according to the outer shape characteristics of the molar to increase the installation stability.

[0020] Preferably, as an improvement, the original tooth mounting portion is only adsorbed on the inner gum surface of the natural tooth.

[0021] The above arrangement reduces the covering of the base on the natural teeth, making it easier to wear, and at the same time effectively reduces the food residues remaining in the gap between the base 1 and the natural teeth, causing oral hygiene problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1-4 As shown, the utility model discloses a removable denture, including a base 1 and a tooth body 2. The base 1 is translucent and has an arc shape. The shape of the base 1 fits the gums. The base 1 includes a false tooth part 11 and an original tooth mounting part 12. The lower part of the false tooth part 11 is a concave wearing groove 13 for fitting with the gums. The upper part of the false tooth part 11 includes a plurality of tooth bodies 2 fixedly mounted on the base 1. The original tooth mounting part 12 is a single-layer structure for avoiding natural teeth. The single-layer structure is only adsorbed on the inner gum surface of the natural teeth, reducing the covering of the natural teeth by the base 1, making it convenient to wear, and effectively reducing the food residues remaining in the gap between the base 1 and the natural teeth, causing oral hygiene problems; as shown Figure 1 As shown, the thickness of the ends of the left and right sides of the base 1 is thinner than the middle part, so as to ensure the comfort of the patient when wearing it.

[0030] Among them, it also includes a fixing structure, which is a mounting bracket 3. The mounting bracket 3 includes a main bracket 31 that is completely embedded in the base 1 and a limiting bracket 32 ​​that is partially embedded in the base 1. The embedding depth h of the main bracket 31 embedded in the base 1 is not less than 1 / 2 of the longitudinal depth H of the base 1, so as to ensure that the mounting bracket 3 can effectively play a role in strengthening the stability of the installation of the removable denture. The main bracket 31 is distributed in the base 1 along the shape of the base 1, and one end of the limiting bracket 32 ​​is fixed to the main bracket 31 by winding to form a whole, so that the overall strength of the mounting bracket 3 is higher and the supporting effect is Better yet, the limiting bracket 32 ​​is fixed on the main bracket 31 to achieve position fixing, and the subsequent production process of the base 1 can effectively avoid the limiting bracket 21 not being fixed and causing unqualified base 1; the number of limiting brackets 32 is determined according to the patient's condition, and there is at least one, and if there are multiple limiting brackets 32, it is ensured that there are distributions on both sides of the base 1; the other end of the limiting bracket 32 ​​is provided with a clamping ring 321 for clamping the natural tooth, and the clamping ring 321 acts on the natural teeth other than the incisors, and the clamping ring 321 surrounds the middle of the natural tooth, and the surrounding size is not less than 1 / 2 of the circumference of the natural tooth; Figure 4 As shown, for the molars among the natural teeth, in order to ensure stable surrounding, the clasp 321 is bent, and the clasp 321 as a whole is parallel to the surface of the natural tooth. At the same time, according to the appearance characteristics of the molars, in addition to the clasp 321, a vertical clasp 322 is also provided. One end of the vertical clasp 322 is fixed on the adjacent limiting bracket 32, and the vertical clasp 322 is bent along the ridge of the molar and buckles the pit and groove of the molar to increase the installation stability and realize the connection and fixation between the installation bracket 3 and the natural tooth.

[0031] The specific implementation process is as follows:

[0032] When in use, the shape of the base 1 and the tooth body 2 are selected according to the patient's condition, and the number and position of the required limiting brackets 32 and the shape of the clasps on the limiting brackets that match the natural teeth are determined. When installing the removable denture, the base 1 is placed just above the lower gum or just below the upper gum, and then the original tooth mounting part 12 is aligned with the natural teeth to complete the adjustment of the installation position of the removable denture. The base 1 is pressed with a little force to make it adsorbed on the gums and the jawbone to achieve adsorption and fixation of the removable denture. At the same time, the clasps 321 and the vertical clasps 322 are used to clamp the natural teeth to achieve dual fixation of the bracket and adsorption of the removable denture, thereby improving the installation stability and effectively reducing the situation in which patients wear full dentures in daily life due to the single fixing method, resulting in oral problems or the removable denture is easy to fall off when the removable denture material ages.
