Description

Technical Field

[0001] This application relates to the field of denture technology, and in particular to a removable denture that is easy to clean. Background Technology

[0002] Removable dentures are commonly used prostheses in the field of dental restoration, used to help patients with missing teeth restore chewing function and improve facial morphology. They mainly consist of a denture body that adapts to oral tissues and implant-related structures for fixed installation. To ensure stability during wear, existing removable dentures often employ an integrated design or a complex fixed connection between the denture body and the implant structure. While these structures can meet basic occlusal needs, they have certain limitations in practical applications.

[0003] On the one hand, the disassembly and assembly of existing removable dentures are relatively complicated. Some structures require the use of professional tools to separate the denture body from the implant structure. Patients usually find it difficult to complete the disassembly and assembly process by themselves. This makes it difficult to thoroughly clean the connection between the denture body and the implant structure during the cleaning process, which can easily create cleaning dead spots.

[0004] On the other hand, the sealing design of the joints of most removable dentures is not perfect. During use, food debris, saliva and other substances can easily seep into the gap between the two. These impurities are difficult to remove by conventional cleaning methods and may also breed bacteria, which will have an adverse effect on oral hygiene and may also cause odor. Utility Model Content

[0005] To address the issues of relatively complex disassembly and assembly and inadequate sealing in existing removable dentures, this application provides a removable denture that is easy to clean.

[0006] This application provides a removable denture that is easy to clean, employing the following technical solution:

[0007] A removable denture that is easy to clean includes a denture body and an implant body that connects to the patient's alveolar bone;

[0008] The assembly groove is located at the bottom end of the denture body, and the inner wall of the top end of the assembly groove is provided with a plurality of annularly distributed limiting protrusions.

[0009] The support is disposed on the top of the planting body, and the outer side of the support is provided with an annular locking groove that engages with the limiting protrusion.

[0010] A sealing ring, which is fitted at the top edge of the planting body;

[0011] The denture body is adapted to the support at the top of the implant body via the mounting groove, and the top of the sealing ring abuts against the bottom edge of the denture body.

[0012] By adopting the above technical solution, during assembly, the mounting groove of the denture body is aligned with the support of the implant body, the limiting protrusion and the annular locking groove form a snap-fit, and the sealing ring and the bottom edge of the denture body form a contact seal. The limiting protrusion and the annular locking groove enable the two to be detachably connected, and the sealing structure can prevent external foreign objects from entering the connection. This allows for the separation and combination of the denture body and the implant body, making it easy to clean them separately, while reducing the possibility of food residue remaining at the connection and optimizing hygiene conditions during use.

[0013] Preferably, the top edge of the support is provided with an annular guide slope, which compresses and guides the limiting protrusion that is engaged in the annular locking groove.

[0014] By adopting the above technical solution, during installation, the limiting protrusion contacts the guide slope. Under the assembly force, the guide slope forms a guiding effect on the limiting protrusion, guiding the limiting protrusion to slide into the annular locking groove. The inclined structure of the guide slope converts the assembly force into a guiding force, assisting the limiting protrusion and the annular locking groove to be accurately aligned. This reduces the misalignment and collision between the limiting protrusion and the bracket during the assembly process, reduces the difficulty of the assembly operation, and reduces hard wear between parts.

[0015] Preferably, the annular locking groove has a chamfered edge at the groove opening.

[0016] By adopting the above technical solution, the cleaning medium can flow into the annular locking groove along the chamfered inclined surface during cleaning. The chamfer eliminates the sharp corner structure of the groove opening. The chamfer structure optimizes the flow path of the cleaning medium and reduces the space for stain adhesion at the groove opening. This improves the cleaning accessibility inside the annular locking groove, reduces the probability of stain residue, and provides a clean mating surface for subsequent assembly.

[0017] Preferably, a supporting slope is provided at the connection between the support and the planting body.

[0018] By adopting the above technical solution, the supporting slope forms support for the bracket, while dispersing the biting force transmitted from the denture body to the connection point. The slope structure increases the force-bearing area of ​​the connection point, so that the biting force is evenly distributed in the connection area between the implant body and the bracket, thereby improving the structural stability of the connection between the bracket and the implant body and reducing the risk of damage caused by local force concentration at the connection point.

[0019] Preferably, the top edge of the planting body is provided with an annular groove that matches the sealing ring, and the top of the sealing ring is flush with the top of the planting body.

[0020] By adopting the above technical solution, the annular groove forms a positioning constraint on the sealing ring, keeping the sealing ring in a fixed position, and the top of the sealing ring is flush with the top of the implant body, ensuring that the denture body and the implant body fit together after assembly. The annular groove restricts the displacement of the sealing ring, and the flush structure ensures the flatness of the assembly surface, thereby improving the sealing stability of the sealing ring, reducing sealing failure caused by the displacement of the sealing ring, and reducing the probability of foreign objects seeping into the connection.

[0021] Preferably, a groove is provided at the center of the top of the support, and a protrusion is provided in the assembly groove at the bottom of the planting body to engage with the groove.

[0022] By adopting the above technical solution, the protrusion is inserted into the groove during assembly to form an auxiliary positioning structure. This structure, together with the limiting protrusion and the annular locking groove, forms a dual positioning. The insertion of the protrusion into the groove restricts the radial displacement of the denture body. The auxiliary locking structure enables precise assembly, thereby reducing the relative offset between the denture body and the implant body after assembly and improving the occlusal alignment accuracy when wearing the denture.

[0023] Preferably, a positioning block in the shape of a flat-topped pyramid is fixed to the inner wall of the bottom of the groove, and a positioning groove adapted to the positioning block is opened at the bottom of the protruding post.

[0024] By adopting the above technical solution, when the protruding post is inserted into the groove, the flat-topped pyramidal positioning block is embedded in the positioning groove to form an anti-rotation constraint. The irregular structure of the positioning block and the positioning groove cooperates to restrict the relative rotation between the denture body and the implant body, thereby further improving the structural stability after assembly, reducing the rotational displacement of the denture body when chewing force is applied, and ensuring the stability of the occlusal function.

[0025] Preferably, the implant body has a threaded groove on the inner side of its bottom end, and the implant body is fixedly connected to the patient's alveolar bone by bolts through the threaded groove.

[0026] By adopting the above technical solution, the bolt forms a fixed connection with the patient's alveolar bone through the threaded groove, and the threaded structure achieves a detachable fastening fit.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Utilizing the snap-fit ​​and detachable structure between the denture body and the implant body, combined with the chamfered guide design of the annular locking groove, the two can be quickly separated for separate cleaning. The cleaning medium can fully enter the mating gap, reducing the probability of stain residue and simplifying the cleaning operation process.

[0029] 2. By utilizing the dual positioning cooperation of protrusions and grooves, positioning blocks and positioning slots, combined with the snap-fit ​​fixation of limiting protrusions and annular locking grooves, the radial displacement and circumferential rotation of the denture body are restricted. At the same time, the sealing ring ensures the sealing effect, improving the bite accuracy and stability during wear. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0038] This application discloses a removable denture that is easy to clean.

[0039] Reference Figure 1 and Figure 2 A removable denture that is easy to clean includes a denture body 2 and an implant body 1 connected to the patient's alveolar bone. A bolt for assembling the implant body 1 is installed on the patient's alveolar bone. A threaded groove 13 is opened on the inner side of the bottom end of the implant body 1. The specification of the threaded groove 13 matches the external thread of the bolt. The bolt is made of medical titanium alloy and is adapted to the implant abutment in the patient's alveolar bone. The denture body 2 is made of medical resin material and the surface is polished, which has both biocompatibility and wear resistance.

[0040] The implant body 1 is connected to the connecting bolts via the threaded groove 13 to achieve fixed installation with the alveolar bone. The threaded connection structure has good self-locking properties, which can ensure the long-term stable fixation of the implant body 1. At the same time, the detachable connection method facilitates subsequent maintenance or replacement. The shape of the denture body 2 is adapted to the shape of natural teeth, ensuring occlusal function and aesthetics. The implant body 1 is made of medical-grade titanium alloy, which is high in strength and not easy to corrode, and can stably fit the alveolar bone environment for a long time.

[0041] Reference Figure 2 The denture body 2 has an assembly groove 3 at its bottom end, and the implant body 1 has an integrally formed support 9 at its top. The assembly groove 3 has a cylindrical groove structure, and the inner diameter of the assembly groove 3 matches the outer diameter of the support 9 at the top of the implant body 1 to ensure a tight fit after assembly. The inner wall of the top of the assembly groove 3 has multiple annularly distributed limiting protrusions 4, preferably 4 to 6, which are evenly distributed along the inner wall of the assembly groove 3. Each limiting protrusion 4 has an arc-shaped block structure with a smooth surface to reduce frictional resistance when engaging with the annular locking groove 14. The support 9 has a cylindrical boss structure and is coaxially set with the implant body 1 to ensure balanced force. The outer side of the support 9 has an annular locking groove 14, the width of which matches the thickness of the limiting protrusion 4, and the depth which is greater than the height of the limiting protrusion 4, so that the limiting protrusion 4 can be completely locked into the groove to form a stable fit.

[0042] The denture body 2 is assembled with the support 9 by insertion and removal through the assembly groove 3. During assembly, the limiting protrusion 4 is engaged and fixed with the annular locking groove 14. At the same time, the sealing ring 8 is in close contact with the bottom edge of the denture body 2 to form a sealing structure, preventing food residue and saliva from entering the connection.

[0043] Reference Figure 5 The top edge of the support 9 is provided with an annular guide slope 15, the angle between the guide slope 15 and the top surface of the support 9 is 30° to 45°, and the surface of the slope is polished.

[0044] When the denture body 2 is assembled downwards, the limiting protrusion 4 first contacts the guide slope 15. Under the action of the pressing axial force, the guide slope 15 converts the axial force into radial extrusion force, guiding the limiting protrusion 4 to slide along the slope and accurately engage with the annular locking groove 14, thus avoiding misalignment and jamming during assembly.

[0045] Reference Figure 5 The annular locking groove 14 has a chamfer 16 at the edge of the groove opening. The radius of the chamfer 16 is 0.5 to 1 mm, and it adopts a rounded transition structure.

[0046] During cleaning, water or cleaning fluid can flow smoothly into the annular locking groove 14 along the curved surface of the chamfer 16, while eliminating dead corners where dirt adheres to the groove opening, allowing the cleaning medium to fully contact all areas inside the groove.

[0047] Figure 3 and Figure 4 A supporting slope 7 is provided at the connection between the support 9 and the planting body 1. The supporting slope 7 extends from the bottom of the support 9 downward to the surface of the planting body 1, forming a transition structure.

[0048] The support slope 7 increases the connection area between the support 9 and the implant body 1, so that the biting force transmitted by the denture body 2 is distributed to the entire implant body 1 through the support 9, avoiding structural damage caused by localized force concentration at the connection.

[0049] Reference Figure 3 and Figure 4 The top edge of the planting body 1 is provided with an annular groove 12. The annular groove 12 has an annular groove structure. The sealing ring 8 is inserted into the annular groove 12. The groove width and groove depth of the annular groove 12 are adapted to the size of the sealing ring 8. The top of the sealing ring 8 is flush with the top of the planting body 1. The sealing ring 8 is made of food-grade silicone material, which has good elasticity and sealing performance. Its outer diameter is flush with the top edge of the planting body 1.

[0050] The annular groove 12 provides circumferential positioning for the sealing ring 8, preventing the sealing ring 8 from shifting or falling off during the assembly and disassembly of the denture body 2. At the same time, it ensures that the bottom of the denture body 2 and the implant body 1 are flat after assembly, avoiding gaps.

[0051] Reference Figure 3 and Figure 4 The top center of the support 9 has a groove 10, which is cylindrical in shape. The mounting groove 3 at the bottom of the denture body 2 has an integrally formed protrusion 5, which is cylindrical in shape. Its outer diameter matches the inner diameter of the groove 10. After assembly, the gap between the two is less than 0.1mm, forming an auxiliary positioning. The bottom inner wall of the groove 10 has an integrally formed positioning block 11 with a flat-topped pyramid shape. The positioning block 11 has 4 to 6 pyramidal faces and a flat top. The bottom of the protrusion 5 has a positioning groove 6 that matches the positioning block 11. The inner wall shape of the positioning groove 6 is completely fitted with the outer shape of the positioning block 11.

[0052] By interlocking the protrusion 5 with the groove 10, the radial displacement of the denture body 2 is further restricted, making the fit between the limiting protrusion 4 and the annular locking groove 14 more precise. When the protrusion 5 is inserted into the groove 10, the positioning block 11 is simultaneously embedded in the positioning groove 6. The pyramidal irregular structure restricts the relative rotation between the denture body 2 and the implant body 1, ensuring that the denture body 2 will not shift circumferentially during occlusion.

[0053] The implementation principle of a removable denture that is easy to clean according to an embodiment of this application is as follows:

[0054] During installation, first install the bolts on the implant abutment in the patient's alveolar bone, then fix the implant body 1 to the bolts on the patient's alveolar bone through the threaded groove 13, so that the implant body 1 is stably installed on the alveolar bone. Then pick up the denture body 2, align the mounting groove 3 at the bottom of the denture body 2 with the support 9 of the implant body 1, align the protrusion 5 with the groove 10 and the positioning groove 6 with the positioning block 11, and press down on the denture body 2.

[0055] During the pressing process, the limiting protrusion 4 contacts the guide slope 15 of the support 9 and slides along the slope under the guidance of the guide slope 15, and finally snaps into the annular locking groove 14 to form a snap-fit ​​fixation, realizing the purpose of quick snap-fit ​​between the denture body 2 and the support 9; at the same time, the protrusion 5 is inserted into the groove 10 and the positioning block 11 is embedded in the positioning groove 6 to complete the double positioning. At this time, under the positioning action of the annular groove 12, the sealing ring 8 is in close contact with the bottom edge of the denture body 2 to form a sealing structure, and the assembly is completed.

[0056] During use, the supporting inclined surface 7 disperses the biting force and avoids force concentration at the connection between the support 9 and the implant body 1; the cooperation between the positioning block 11 and the positioning groove 6 prevents the denture body 2 from rotating, and the protrusion 5 and the groove 10 limit radial displacement to ensure biting stability; the sealing ring 8 prevents foreign objects from entering the connection and reduces stain residue.

[0057] When cleaning is required, simply pull the denture body 2 upwards to disengage the limiting protrusion 4 from the annular locking groove 14, thus separating the denture body 2 from the implant body 1 and achieving quick disassembly of the denture body 2. When cleaning both, the chamfer 16 of the annular locking groove 14 guides the cleaning medium into the groove to thoroughly remove residual stains. After cleaning, reinstall according to the assembly steps described above to achieve convenient and efficient cleaning operation.

[0058] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
