Description

Technical Field

[0001] This utility model relates to the technical field of positioning and installation accessories for zirconia blocks in all-ceramic dentures, specifically to an elastic positioning hoop for zirconia blocks in all-ceramic dentures. Background Technology

[0002] Zirconia blocks for all-ceramic dentures are widely accepted by dentists as a primary material for dental restorations. However, due to differences in raw material sources, pre-firing processes, and equipment performance among manufacturers of zirconia blocks for all-ceramic dentures, their density, light transmittance, and other properties vary. This necessitates that dental technicians accurately understand the various performance indicators of zirconia blocks for all-ceramic dentures before fabricating dental restorations.

[0003] Application number CN202020938581.4 discloses a clamp for positioning and installing zirconia blocks in all-ceramic dentures. The clamp has a tubular structure, with both its outer and inner surfaces being smooth or rough. It is made of a heat-shrinkable or elastic polymer material, and its outer surface displays product information for the zirconia blocks. This invention significantly improves the convenience and reliability of clamp installation and the safety of using zirconia blocks in all-ceramic dentures. It further increases the friction between the clamp and the zirconia blocks, creating a high holding force that meets the requirements for stable installation, positioning, and clamping during CAD / CAM processing of dental restorations, exhibiting high processing stability.

[0004] However, the elastic modulus of this clamp is different from that of the zirconia block. When subjected to high-frequency vibration or axial cutting force during long-term CAD / CAM processing, the elastic fatigue of the material will lead to the attenuation of the preload. For smooth zirconia blocks, if the inner surface of the clamp relies only on the rough texture to provide friction, the engagement between the texture and the micro-protrusions on the surface of the zirconia block is insufficient, which can easily cause it to fall off. Therefore, an elastic positioning clamp for zirconia blocks in all-ceramic dentures is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an elastic positioning ring for zirconia blocks in all-ceramic dentures.

[0006] The technical solution adopted by this utility model to solve its technical problem is an elastic positioning ring for a zirconia block in an all-ceramic denture, including a wear-resistant outer ring and an anti-slip inner ring. The inner side of the wear-resistant outer ring is provided with an installation groove for the anti-slip inner ring to be installed and embedded. The inner side of the anti-slip inner ring is provided with a second anti-slip surface. The opposite inner sides of the installation groove are provided with a first anti-slip surface. The outer side of the wear-resistant outer ring is provided with a third anti-slip surface.

[0007] By adopting the above technical solution and employing a three-sided anti-slip design, the second anti-slip surface on the inner side of the anti-slip inner ring fits into the arc-shaped edge of the porcelain block, the first anti-slip surfaces on both sides of the mounting groove fit into the two sides of the porcelain block, and the third anti-slip surface on the outer side of the wear-resistant outer ring increases external friction, making it easier for users to pick up the zirconia porcelain block of the all-ceramic denture, preventing the collar and porcelain block from falling off in all directions, and ensuring stability during use.

[0008] Specifically, a positioning groove is provided on the inner side of the mounting groove, and there are multiple positioning grooves.

[0009] By adopting the above technical solution, before installing the anti-slip inner ring, it is necessary to confirm the position of the positioning groove. These positioning grooves are evenly distributed along the inner wall of the installation groove, providing clear positional guidance for the accurate installation of the anti-slip inner ring.

[0010] Specifically, the positioning grooves are provided for the installation and insertion of positioning blocks. Multiple positioning blocks are provided, and the multiple positioning blocks are fixedly connected to the outer side of the anti-slip inner ring.

[0011] By adopting the above technical solution, when installing the anti-slip inner ring, multiple positioning blocks on its outer side are inserted one by one into the positioning grooves in the installation groove to ensure the accurate installation position of the anti-slip inner ring and prevent displacement during the installation process.

[0012] Specifically, an adhesive layer is pasted on the outer side of the anti-slip inner ring, and the anti-slip inner ring is bonded to the inside of the mounting groove through the adhesive layer.

[0013] By adopting the above technical solution, after the positioning block is fully inserted into the positioning groove, the anti-slip inner ring is pressed to make its outer adhesive layer fully contact and bond with the inner wall of the mounting groove, which further enhances the connection stability between the anti-slip inner ring and the wear-resistant outer ring and prevents the anti-slip inner ring from loosening during use.

[0014] Specifically, the inner side of the anti-slip inner ring is provided with a finger groove, and the inner side of the finger groove is provided with a disassembly groove.

[0015] By adopting the above technical solution, when the anti-slip inner ring needs to be replaced due to wear and tear from prolonged use, simply insert your finger into the finger groove, then horizontally hook your fingertip into the disassembly groove, and pull forcefully along the inner wall of the mounting groove to easily remove the anti-slip inner ring from the mounting groove. The operation is simple and convenient.

[0016] The beneficial effects of this utility model are:

[0017] The present invention discloses an elastic positioning collar for zirconia blocks in all-ceramic dentures, which adopts a three-sided anti-slip design. The second anti-slip surface on the inner side of the anti-slip inner ring fits into the arc-shaped edge of the porcelain block, the first anti-slip surfaces on both sides of the mounting groove fit into the two sides of the porcelain block, and the third anti-slip surface on the outer side of the wear-resistant outer ring increases external friction, making it easier for users to pick up the zirconia blocks in all-ceramic dentures. This comprehensively prevents the collar from falling off the porcelain block and ensures stability during use.

[0018] The present invention relates to an elastic positioning ring for zirconia blocks in all-ceramic dentures. The anti-slip inner ring is connected to the wear-resistant outer ring through a positioning block and an adhesive layer. When replacing, it can be easily removed using only the finger groove and the disassembly groove, without the need for complicated tools. When installing a new anti-slip inner ring, the positioning block is quickly aligned with the positioning groove, and the adhesive layer is used to achieve a tight fit. This greatly shortens the replacement time, reduces the cost of use, and improves the product's service life and economy. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As one embodiment of this utility model, such as Figures 1-3 As shown, the zirconia block elastic positioning ring of the all-ceramic denture of this utility model includes a wear-resistant outer ring 1 and an anti-slip inner ring 3. The inner side of the wear-resistant outer ring 1 is provided with an installation groove 4 for the anti-slip inner ring 3 to be installed and embedded. The inner side of the anti-slip inner ring 3 is provided with a second anti-slip surface 9. The opposite inner sides of the installation groove 4 are provided with a first anti-slip surface 2. The outer side of the wear-resistant outer ring 1 is provided with a third anti-slip surface 11.

[0026] When in use, the wear-resistant outer ring 1 is placed on the outside of the zirconia ceramic block of the all-ceramic denture, so that the edge of the ceramic block is inserted into the mounting groove 4. At this time, the second anti-slip surface 9 on the inner side of the anti-slip inner ring 3 is in close contact with the arc-shaped edge of the ceramic block, and the first anti-slip surfaces 2 on both sides of the mounting groove 4 are in contact with the two sides of the ceramic block, forming a three-sided anti-slip structure, which effectively prevents the ring from falling off the ceramic block. The third anti-slip surface 11 on the outer side of the wear-resistant outer ring increases the external friction, making it easier for the user to pick up the zirconia ceramic block of the all-ceramic denture.

[0027] This utility model also includes a positioning groove 10 provided on the inner side of the mounting groove 4, and the positioning groove 10 is provided in multiple places.

[0028] Before installing the anti-slip inner ring 3, the position of the positioning groove 10 must be confirmed. These positioning grooves 10 are evenly distributed along the inner wall of the mounting groove 4, providing clear positional guidance for the accurate installation of the anti-slip inner ring 3.

[0029] This utility model also includes multiple positioning grooves 10 for the installation and insertion of positioning blocks 5, and multiple positioning blocks 5 are provided, with multiple positioning blocks 5 fixedly connected to the outside of the anti-slip inner ring 3.

[0030] When using the anti-slip inner ring 3, insert the multiple positioning blocks 5 on its outer side into the positioning slots 10 in the mounting slot 4 one by one to ensure that the anti-slip inner ring 3 is installed in a precise position and to prevent displacement during the installation process.

[0031] This utility model also includes an adhesive layer 6 pasted on the outer side of the anti-slip inner ring 3, and the anti-slip inner ring 3 is bonded to the inside of the mounting groove 4 through the adhesive layer 6.

[0032] When in use, after the positioning block 5 is fully inserted into the positioning groove 10, press the anti-slip inner ring 3 so that the adhesive layer 6 on its outer side can fully contact and bond with the inner wall of the mounting groove 4, further enhancing the connection stability between the anti-slip inner ring 3 and the wear-resistant outer ring 1, and preventing the anti-slip inner ring 3 from loosening during use.

[0033] The present invention also includes a finger groove 7 on the inner side of the anti-slip inner ring 3, and a disassembly groove 8 on the inner side of the finger groove 7.

[0034] When the anti-slip inner ring 3 needs to be replaced due to wear and tear after prolonged use, simply insert your finger into the finger groove 7, then horizontally insert your fingertip into the disassembly groove 8, and pull it forcefully along the inner wall of the mounting groove 4 to easily remove the anti-slip inner ring 3 from the mounting groove 4.

[0035] In use, the wear-resistant outer ring 1 is fitted onto the outside of the zirconia ceramic block of the all-ceramic denture, so that the edge of the zirconia ceramic block can fit perfectly into the mounting groove 4. The second anti-slip surface 9 on the inner side of the anti-slip inner ring 3 is attached to the arc-shaped edge of the zirconia ceramic block. The first anti-slip surfaces 2 on both sides of the mounting groove 4 can be attached to the two sides of the zirconia ceramic block. This fitting method can prevent the ring from falling off the zirconia ceramic block. When the anti-slip inner ring 3 wears down due to long-term use, you can insert your finger into the finger groove 7 and horizontally hook it into the disassembly groove 8, and forcefully pull the anti-slip inner ring 3 out of the mounting groove 4, so that you can replace it with a new one. To replace the new anti-slip inner ring 3, simply align the positioning block 5 with the positioning groove 10 on the inner side of the mounting groove 4 and insert it. The adhesive layer 6 of the anti-slip inner ring 3 can fit tightly against the inner side of the mounting groove 4.
