Description

Technical Field

[0001] The present application relates to the technical field of dentures, and in particular to a multi-piece denture. Background Art

[0002] Complete dentures are a standard restorative treatment for edentulous patients. They consist of two components: artificial teeth and a base. The artificial teeth are attached to the base to restore the shape and occlusion of the missing teeth. The base adheres to the supporting tissue, providing retention and stability for the denture. It also transmits the bite forces generated by the artificial teeth to the supporting tissue and restores the morphology of the missing alveolar ridge tissue.

[0003] The artificial teeth and base of traditional dentures are fixed. When some of the artificial teeth are damaged, they need to be replaced as a whole, which is not only expensive but also inconvenient. For this reason, some manufacturers have improved traditional dentures, such as the "detachable denture" disclosed in the patent document "CN214434594U", in which the artificial teeth and base parts are detachable. In this way, when an artificial tooth is damaged, it only needs to be replaced individually instead of as a whole. In further research, the present application found that even for the artificial tooth part, the damaged part is generally the crown part of the end face, because it is the direct contact part during chewing, and the probability of damage to the root is relatively small. For this reason, the present application aims to further improve the solution based on this phenomenon. Utility Model Content

[0004] The purpose of this application is to provide a multi-piece denture to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a multi-piece denture, comprising a base and a denture body arranged on the base, wherein the denture body comprises a crown portion, a root portion and a mounting portion connected in sequence from top to bottom;

[0006] The mounting portion is connected to the base, the tooth root portion is detachably mounted on the mounting portion, and the tooth crown portion is detachably mounted on the tooth root portion;

[0007] A boss is formed at one end of the root portion close to the crown portion, a first groove adapted to the boss is formed at one end of the crown portion close to the root portion, a first magnetic member is provided on the outer peripheral wall of the boss, and a second magnetic member adapted to the first magnetic member is provided on the inner peripheral wall of the first groove;

[0008] A platform portion is formed on the tooth root portion around the boss, a clamping ball is formed on the platform portion, and a clamping piece adapted to the clamping ball is formed on one end of the crown portion close to the tooth root portion, and a clamping groove is formed on the clamping piece;

[0009] In the above implementation process, the denture body provided in this solution consists of three parts, wherein the mounting portion is used to realize the installation of the denture body as a whole on the base, the crown portion is the main chewing contact position during use, and the root portion connects the crown portion and the mounting portion; in actual use, the mounting portion can be assembled on the base first, and then the root portion and the crown portion can be assembled in sequence, or the entire denture body can be assembled first, and then the entire denture body can be assembled on the base; in this solution, when the crown portion is connected to the root portion, the boss of the root portion can be stuck in the first groove of the crown portion to realize The first connection is achieved, and the first magnetic part and the second magnetic part cooperate to achieve magnetic attraction, thereby achieving the second connection guarantee between the two. Furthermore, the snap-in ball located on the root part can be snap-fitted with the snap-in part on the crown part, thereby achieving the third connection guarantee between the two, so as to fully achieve a stable connection between the two. At the same time, the above-mentioned triple connections can be disassembled later, and then in the subsequent use process, if only the crown part is damaged, the user can only remove the crown part without replacing the entire denture body, which effectively extends its service life.

[0010] Preferably, a through groove is formed at the axis of the tooth root, and a step structure is formed in the through groove;

[0011] A mounting groove is formed at one end of the mounting portion close to the tooth root portion, and an internal thread is formed in the mounting groove;

[0012] The invention also includes a first fixing member, wherein the first fixing member is adapted to penetrate the through slot and cooperate with the mounting slot to lock the tooth root portion and the mounting portion;

[0013] In the above implementation process, the root pressing part is first abutted against the end face of the mounting part, the through groove is aligned with the mounting groove, and then the first fixing part is inserted through the through groove. The first fixing part can be rotated to achieve the connection between the root part and the mounting part. Similarly, when disassembling, the first fixing part can be rotated in the opposite direction to disengage the first fixing part from the mounting groove, thereby releasing the connection between the root part and the mounting part; the step structure serves to limit the first fixing part.

[0014] Preferably, a limiting block is formed at the bottom of the tooth root portion, and a limiting groove adapted to the limiting block is formed at the end of the mounting portion;

[0018] Preferably, the antibacterial layer is a silicon dioxide coating or a silver ion coating;

[0019] In the above implementation process, this solution selects silica coating or silver ion coating as the antibacterial layer, both of which have excellent antibacterial properties, thereby effectively improving the antibacterial properties of the crown part.

[0020] Preferably, the base layer is a cobalt-chromium alloy layer;

[0021] In the above implementation process, the cobalt-chromium alloy itself has strong corrosion resistance and is light in weight, which can reduce the burden of wearing. Furthermore, it has little taste interference and is suitable as the base material of the crown.

Furthermore, the snap-in ball located on the root portion can be snap-fitted with the snap-in part on the crown portion, thereby achieving a third connection guarantee between the two, so as to fully achieve a stable connection between the two. At the same time, the above-mentioned triple connections can be disassembled later, and then in the subsequent use process, if only the crown portion is damaged, the user can only remove the crown portion without replacing the entire denture body, thereby effectively extending its service life.
