Description

Technical Field

[0001] The utility model relates to the field of fixed dentures, in particular to 3D porcelain veneer fixed dentures. Background Art

[0002] Dentures, commonly known as false teeth, are dentures that help people chew when their natural teeth are missing. Fixed dentures use the healthy teeth on both sides of the missing teeth as supports to fix the false teeth in the oral cavity, and are suitable for the situation where a small number of teeth are missing and the remaining teeth are in good health.

[0003] Currently, most of the existing fixed dentures often need to grind the teeth on both sides when reconstructing fixed dentures, add metal sleeves on the teeth on both sides, weld connecting beams between the sleeves, and then form the shape of the denture on the connecting beam. The fixing method of the metal sleeve is likely to affect the aesthetics of the teeth on both sides and cause defects and allergies to the natural teeth. However, this method has poor stability. There is also a method of using implants and bolts to reconstruct fixed dentures. Although it meets the stability in one aspect, a certain amount of composite resin needs to be filled above the main body of the denture to achieve the aesthetics of the outside of the denture and the connection with the internal bolts. However, since the composite resin fills the groove holes in the middle of the denture, this kind of pouring columnar filling makes the middle of the denture mainly rely on the composite resin for chewing and support during use. After long-term use, the columnar composite resin is prone to cracks and breakages. At this time, the internal bolts will be exposed, affecting the aesthetics and also correspondingly easily affecting the internal connection of the denture, and unable to meet the actual use requirements.

[0004] Therefore, it is necessary to provide 3D porcelain veneer fixed dentures to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the embodiment of the utility model is to provide 3D porcelain veneer fixed dentures, aiming to solve the technical problems raised in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] The 3D porcelain veneer fixed denture includes an implant and a denture body installed on the implant. The top of the denture body penetrates into the interior of the implant and is provided with an installation groove, and the installation groove is provided with:

[0008] A locking mechanism for limiting and locking the implant and the denture body, wherein the locking mechanism includes a screw cap for screwing and fixing; and

[0009] A sealing and filling mechanism installed between the screw cap and the denture body, and the sealing and filling mechanism includes:

[0010] Reinforcing rings and reinforcing ribs, with the number of reinforcing ribs being several and fixedly installed on the outer side of the reinforcing ring. The reinforcing ribs are connected to the installation groove by interference fit, and the reinforcing ring is fixedly installed above the screw cap; and

[0011] Liquid guiding holes are opened on the screw cap, which are used for draining the composite resin during filling and for connection and fixation on the outer side of the screw cap.

[0012] As a further solution of the present utility model, a cross slot for installation is opened on the screw cap, and an annular slot adjacent to the liquid guiding hole is opened on the inner side of the denture body.

[0013] As a further solution of the present utility model, the locking mechanism further includes a fixing rod and a threaded rod fixedly connected to the screw cap in sequence, and a threaded groove threadedly connected to the threaded rod is opened inside the implant.

[0014] As a further solution of the present utility model, the locking mechanism further includes a limiting insertion rod for limiting the installation of the fixing rod and the threaded rod. The limiting insertion rod is slidably connected to the inside of the fixing rod through a limiting slider, and a spring is arranged at the connection between the limiting insertion rod and the inside of the fixing rod.

[0015] As a further solution of the present utility model, an introduction bevel for fitting into the installation groove is opened at one end of the fixing rod, and a limiting groove for fitting and limiting the connection of the limiting insertion rod is opened inside the implant.

[0016] As a further solution of the present utility model, a buffer layer for buffering is arranged at the bottom of the installation groove, and the threaded rod is installed above the buffer layer.

[0017] In summary, the embodiments of the present utility model have the following beneficial effects compared with the prior art:

[0018] The present utility model can achieve the fixation of the screwed connection of the fixing rod through the provided locking mechanism, greatly improving the installation stability of the denture body, and avoiding the damage caused by the shaking and instability of the denture body during long-term use.

[0019] Through the provided sealing and filling mechanism, the composite resin can be filled after the locking mechanism is installed and fixed. The filled colloid can enter the annular groove on the inner side of the denture body from the cross slot on the screw cap and the connected liquid guiding holes. When the annular groove is filled with the composite resin, at this time, the composite resin fills the outer periphery of the reinforcing ring and the reinforcing ribs. Moreover, the annular sealing composite resin formed at the annular groove forms the fixation between the screw cap and the inner side of the denture body under the action of light curing, with good stability. And the provided reinforcing ring and reinforcing ribs form a support framework for the internal filling of the composite resin, thereby further ensuring the installation stability of the composite resin, enhancing the support force and compressive resistance of the overall denture body during chewing, and improving the service life of the denture body.

[0035] A reinforcing ring 8 and reinforcing ribs 9, and the number of the reinforcing ribs 9 is several and fixedly installed on the outer side of the reinforcing ring 8. The reinforcing ribs 9 are in interference fit connection with the installation groove 3, and the reinforcing ring 8 is fixedly installed above the cap 5; and

[0036] A liquid guiding hole 11 is opened on the cap 5 for draining the composite resin 4 to be filled and for connection and fixation on the outer side of the cap 5.

[0037] Furthermore, a cross slot 10 for installation is opened on the cap 5, and an annular groove 12 adjacent to the liquid guiding hole 11 is opened on the inner side of the denture body 1.

[0038] Preferably, during the actual installation operation, the locking mechanism is mainly installed inside the installation groove 3 through the cross slot 10 on the cap 5. A certain amount of composite resin 4 is filled above the installation groove 3 and the cap 5. At this time, the composite resin 4 fills the outer periphery of the reinforcing ring 8 and the reinforcing ribs 9, so as to facilitate the connection between the cap 5 and the denture body 1;

[0039] Among them, it should be particularly noted that the filled colloid can enter the annular groove 12 on the inner side of the denture body 1 from the cross slot 10 on the cap 5 and the connected liquid guiding hole 11. When the annular groove 12 is filled with the composite resin 4, at this time, the composite resin 4 fills the outer periphery of the reinforcing ring 8 and the reinforcing ribs 9. And the annular sealing composite resin 4 formed at the annular groove 12 is fixed on the inner side of the cap 5 and the denture body 1 under the action of light curing, with good stability. And the support framework filled inside the composite resin 4 is formed by the arranged reinforcing ring 8 and reinforcing ribs 9, thereby further ensuring the stability of the installation of the composite resin 4, improving the support force and compression resistance of the whole denture body 1 during chewing, and extending the service life of the denture body 1.

[0040] Embodiment 2

[0041] As Figures 1 to 7 shown, on the basis of Embodiment 1, the locking mechanism further includes a fixing rod 6 and a threaded rod 7 fixedly connected to the cap 5 in sequence, and a threaded groove 18 threadedly connected to the threaded rod 7 is opened inside the implant 2.

[0042] Furthermore, the locking mechanism further includes a limiting insertion rod 13 for limiting the installation of the fixing rod 6 and the threaded rod 7.

[0043] Furthermore, an introduction bevel 19 for fitting into the installation groove 3 is provided at one end of the fixing rod 6, and a limiting groove 16 for fitting and limiting the connection of the limiting insertion rod 13 is provided inside the implant 2.

[0044] Furthermore, a buffer layer 17 for buffering is provided at the bottom of the installation groove 3, and the threaded rod 7 is installed above the buffer layer 17.

[0045] It should be particularly noted that the material used for the buffer layer 17 includes but is not limited to rubber materials. The buffer layer 17 made of rubber material has elasticity and softness, and can effectively reduce the installation damage caused during the installation process.

[0046] Preferably, in this embodiment, during the actual installation operation, the threaded rod 7 is screwed into the internal thread groove 18 through the rotary cap 5 and the fixing rod 6. At this time, the limiting insertion rod 13 on the fixing rod 6 is under the action of extrusion inside the introduction bevel 19 and the installation groove 3, so that the limiting insertion rod 13 on the fixing rod 6 compresses the spring 15 and is in a compressed state. When the bottom of the threaded rod 7 comes into extrusion contact with the buffer layer 17 below, at this time, the limiting insertion rod 13 just reaches the inside of the limiting groove 16. At this time, under the elastic force of the spring 15, the limiting insertion rod 13 is driven to insert into the inside of the limiting groove 16 for limiting, thus well realizing the fixation of the screwed connection of the fixing rod 6, greatly improving the installation stability of the denture body 1, and avoiding the phenomenon of shaking and instability of the denture body 1 during long-term use and damage.
