Description

Technical Field

[0001] The utility model relates to medical dental restoration products, in particular to a removable denture which is convenient for disassembly and assembly. Background Art

[0002] The professional name of a removable denture is a removable partial denture, including a removable partial denture and a complete denture. It uses artificial teeth to restore the shape and function of missing teeth. It is a prosthesis that patients can remove and wear by themselves. It is a false tooth inlaid to restore functions such as chewing, aesthetics, and pronunciation after teeth fall out or are extracted. Existing removable dentures generally include: a dental base and false teeth fixed on the dental base. Hooks and a base plate are fixed on the dental base. During the installation process of the removable denture, the staff first places the base plate on the gum, and then uses the hooks to hang the removable denture on the adjacent natural teeth to achieve the installation of the removable denture in the oral cavity.

[0003] During the use of existing removable dentures by customized users, during the collision and occlusion process, the removable denture squeezes the gums at the corresponding positions. After long-term use, the area fitting the gums is prone to inflammation. And when chewing hard foods, the denture itself is also prone to damage, and the actual use effect is poor; the teeth and the bottom base plate are often integrally fixed together by gluing. The false teeth and the base plate are not detachable. If multiple dentures are adjacent, when an individual denture is damaged, it is necessary to remove multiple dentures together with the base plate, and it is impossible to independently remove only the denture for targeted repair or replacement, and the practicability is poor.

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] See Figure 1 , the present invention provides a removable denture that is easy to disassemble and assemble, including a base 1 and a denture body 2. A groove 101 for receiving the insertion of the denture body 2 is provided on the base 1. A cylindrical tube 201 is provided at the bottom of the denture body 2. The cylindrical tube 201 is located in the groove 101. An opening 202 is provided in the lower part of the wall of the cylindrical tube 201. A ball 203 is accommodated in the opening 202. An inner column 3 is provided inside the denture body 2. The inner column 3 has a highest position and a lowest position. The inner column 3 cooperates with the ball 203.

[0027] See Figure 2 , the groove 101 on the base 1 is composed of two cylinders up and down. The diameter of the upper cylinder is smaller than that of the lower cylinder. A tooth groove 102 for receiving the denture body 2 is provided on the upper surface of the base 1. The tooth groove 102 is circumferentially arranged around the groove 101.

[0028] See Figure 1 , the length of the cylindrical tube 201 is equal to the depth of the groove 101. The diameter of the cylindrical tube 201 is slightly smaller than the diameter of the upper part of the groove 101. The distance from the upper end of the cylindrical tube 201 to the opening 202 is equal to the length of the upper part of the groove 101. The distance from the opening 202 of the cylindrical tube 201 to the lower end is equal to the length of the lower part of the groove 101.

[0029] The ball 203 is loosely sleeved in the opening 202. The diameter of the opening 202 is larger than that of the ball 203. A boss 204 is provided at the inner wall edge of the opening 202. The diameter of the circle formed by the boss 204 is smaller than that of the ball 203. The wall thickness of the cylindrical barrel 201 is smaller than that of the ball 203. The ball 203 can move within the opening 202 and can partially protrude from the opening 202 without falling off.

[0030] The interior of the denture body 2 is hollow to form a cavity 205. The cylindrical barrel 201 communicates with the interior of the denture body 2. The cavity 205 and the interior of the cylindrical barrel 201 form a receiving cavity. An inner column 3 is provided in the receiving cavity. The inner column 3 includes an upper rod 301, a convex disk 302 connected to the bottom of the upper rod 301, and a lower rod 303 connected to the bottom of the convex disk 302. A spherical groove 304 is recessed in the peripheral surface of the lower rod 303 below the lower rod 303.

[0031] A limiting block 206 protruding from the side wall is provided on the side wall of the cavity 205. The limiting block 206 limits the lowest position of the inner column 3. When the inner column 3 abuts against the limiting block 206, the spherical groove 304 is located below the opening 202. At this time, the distance between the upper rod 301 and the upper surface of the interior of the denture body 2 is equal to the vertical height difference between the center of the spherical groove 304 and the center of the opening 202.

[0032] See Figure 3 and Figure 4 , the inner column 3 has a highest position and a lowest position. When the inner column 3 is at the lowest position, the convex disk 302 abuts against the limiting block 206, the spherical groove 304 is located below the opening 202, and the peripheral wall of the inner column 3 abuts against the ball 203, and the ball 203 partially protrudes outside the cylindrical barrel 201; when the inner column 3 is at the highest position, the spherical groove 304 is flush with the opening 202, the upper end of the inner column 3 abuts against the denture body 2, and the ball 203 partially protrudes inside the cylindrical barrel 201 and is located in the spherical groove 304.

[0033] A spring 4 is provided on the lower surface of the convex disk 302. The other end of the spring 4 is fixedly connected to the upper surface of the bottom of the denture body 2. When the inner column 3 is at the lowest position, the spring 4 is in a natural elongation state; when the inner column 3 is at the highest position, the spring 4 is in a stretched state.

[0034] The convex disk 302 of the inner column 3 is made of one of the materials of gold alloy, titanium alloy, pure titanium, nickel-chromium alloy, and cobalt-chromium alloy. The convex disk 302 is driven by a magnet 5. The magnet 5 is a permanent magnet neodymium iron boron. The magnetic force of the magnet 5 on the convex disk 302 is greater than the elastic force of the spring 4. When the magnet 5 acts on the convex disk 302, the inner column 3 can overcome the elastic force of the spring 4 and displace to the highest position.

[0035] When installing the removable denture, place the magnet 5 directly above the removable denture. The magnet 5 attracts the convex disk 302, moving the inner column 3 from the lowest position to the highest position. When the inner column 3 is at the highest position, the ball 203 does not protrude from the inner column 3. Move the denture body 2 downward, and the lower part of the denture body 2 contacts the alveolus 102 on the base 1. The opening 202 of the cylindrical barrel 201 is located inside the lower part of the groove 101. At this time, remove the magnet 5. Under the action of the spring 4, the spring 4 pulls the inner column 3 downward, and the convex disk 302 abuts against the limit block 206. The inner column 3 is at the lowest position, and the ball 203 partially protrudes outside the cylindrical barrel 201. The ball 203 is located at the junction of the upper and lower parts of the groove 101 and abuts against the inner wall of the groove 101, thereby clamping the denture body 2 inside the base 1. When removing the removable denture, place the magnet 5 directly above the removable denture. The magnet 5 attracts the convex disk 302, moving the inner column 3 from the lowest position to the highest position. The ball 203 does not protrude from the inner column 3. Move the denture body 2 upward and pull out the denture body 2.
