Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of edentulous jaw implantation, in particular to an oral implantation scanning device for a plurality of continuously missing teeth. Background Art
[0002] Oral implants are an advanced method for restoring missing teeth. They involve implanting an artificial tooth root (implant) into the alveolar bone. After a period of healing, the implant forms a secure bond with the bone. An abutment and crown are then installed on the implant, restoring the form and function of the missing tooth. Oral implants offer numerous advantages, including high stability, chewing efficiency similar to natural teeth, aesthetic comfort, and no damage to adjacent teeth.
[0003] Implant placement in multiple consecutively missing teeth or in edentulous jaws are two common scenarios for dental implant placement. In both cases, scanning is necessary during the implant process. Scanning provides an accurate 3D model of the patient's oral cavity, helping the surgeon gain a more comprehensive and precise understanding of key information such as alveolar bone morphology, structure, and bone mass. The actual scanning process requires the assistance of a scanning arm to ensure data continuity and capture full-mouth data.
[0004] In the prior art, a scanning rod mainly consists of a clamping member and a connecting rod body. The clamping member is used to clamp the patient's implant, and the connecting rod is usually linear and used to connect adjacent scanning rods. In actual application, the following problems exist:
[0005] First, as we all know, both the upper and lower jaws of patients are curved, and this curvature varies from patient to patient. A straight connecting rod would protrude from the upper or lower jaw, making it difficult to perfectly fit the patient's upper or lower jaw. This not only affects patient comfort but also increases the difficulty of oral scanning.
[0006] Second, the connecting rod has a fixed length and can only be used for two implants with a fixed distance, resulting in a narrow scope of use.

DETAILED DESCRIPTION
[0036] Example
[0037] Please refer to Figures 1-6 , an oral implant scanning device for multiple consecutively missing teeth, comprising:
[0038] The clamping member 100 is used to clamp the patient's implant; and the first telescopic deformation component includes a first telescopic section 200 and a first plastic rod 500, both of which are arranged outside the above-mentioned clamping member 100. The above-mentioned first plastic rod 500 is used for bending and deformation. The above-mentioned first telescopic section 200 connects the above-mentioned first plastic rod 500 and the above-mentioned clamping member 100. When the above-mentioned first telescopic section 200 telescopes and changes, the above-mentioned first plastic rod 500 moves closer to or away from the above-mentioned clamping member 100.
[0039] This device is primarily used for scanning implants in patients with multiple consecutively missing teeth or in edentulous jaws. In practical application, sufficient preparation is required. Specifically, multiple scanning devices must be prepared, and the number of scanning devices must match the number of implants. Each of these scanning devices is connected to a corresponding number of implants. For each scanning device, the clamping member 100 is first used to firmly grasp the patient's implants. The first telescopic section 200 is then adjusted to adjust its extension. This allows the first telescopic component to extend to the surrounding area of the adjacent scanning device, or to overlap and intersect with the first telescopic component of the adjacent scanning device. This effectively avoids gaps and data loss. This design gives the device the significant advantage of wide applicability, successfully resolving the problem of traditional scanning devices being limited to scanning implants with fixed spacing. Furthermore, the bending deformation of the first plastic rod 500 can be flexibly adjusted to perfectly conform to the curvature of the patient's maxilla or mandible. This prevents rod protrusion, significantly improving patient comfort and significantly reducing the difficulty of oral scanning, bringing significant convenience.
[0040] It's worth noting that if the rod protrudes beyond the upper or lower jaw, it will contact the upper or lower lip, causing a foreign body sensation in the patient and significantly reducing comfort. Furthermore, the protrusion of the rod can severely interfere with the scanner's scanning path, making scanning difficult and significantly reducing scanning efficiency. However, the design of this application can completely overcome these problems.
[0041] The first plastic rod 500 is made of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or rubber. When the first plastic rod 500 is bent by force, it can maintain the bent shape. If it wants to recover its deformation, it needs external force to achieve it.
[0042] In some embodiments of the present invention, the scanning device further includes a second telescopic deformation component, which includes: a second plastic rod 600 for bending and deforming; a second telescopic section 300, connecting the first plastic rod 500 and the second plastic rod 600. When the second telescopic section 300 changes, the second plastic rod 600 moves closer to or away from the first plastic rod 500.
[0043] In the above embodiment, the second deformable rod 600 is also made of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or rubber. When the first deformable rod 500 is bent under force, it maintains its bent shape. Restoring the deformed rod requires external force. The first and second telescopic deformable components comprise the rod of the scanning device. The multi-segment design offers the advantage of high flexibility.
[0044] In some embodiments of the present invention, the first plastic-changing rod 500 is axially provided with a plurality of first clamping platforms 800 , and the second plastic-changing rod 600 is axially provided with a plurality of second clamping platforms 900 .
[0045] In the above embodiment, when adjacent scanning devices are docked, the plurality of first card stages 800 of the adjacent scanning devices are arranged in a staggered manner, and the plurality of second card stages 900 are arranged in a staggered manner, so as to improve the stability of the connection between the two.
[0046] Specifically, any first clamping platform 800 and the first plastic-changing rod 500 are made of the same material, and the first clamping platform 800 is arranged around the circumference of the first plastic-changing rod 500. Any second clamping platform 900 and the second plastic-changing rod 600 are made of the same material, and the second clamping platform 900 is arranged around the circumference of the second plastic-changing rod 600.
[0047] In some embodiments of the present invention, the second telescopic deformation assembly further includes a third telescopic joint 400, one end of the third telescopic joint 400 is arranged on the second plastic rod body 600, and the second telescopic joint 300 and the third telescopic joint 400 are respectively located at both ends of the second plastic rod body 600.
[0048] In the above embodiment, after the first telescopic deformation component and the second telescopic deformation component are installed on the upper jaw or lower jaw, the tail of the rod body can be fine-tuned through the third telescopic joint 400 to avoid discontinuity and the need for reinstallation.
[0049] In some embodiments of the present invention, the first telescopic section 200, the second telescopic section 300 and the third telescopic section 400 all include a fixed seat 220 and an adjusting rod 210. The fixed seat 220 is arranged on the clamping member 100, the first plastic-changing rod body 500 or the second plastic-changing rod body 600. The fixed seat 220 is provided with a first slot, and the adjusting rod 210 can be telescopically arranged in the first slot.
[0050] In the above embodiment, the telescopic cooperation of the adjusting rod 210 and the fixing seat 220 can achieve the length change of the first telescopic section 200, the second telescopic section 300 or the third telescopic section 400 to adapt to the length change of the rod body, which has a wider range of applications and is more practical.
[0051] Specifically, the fixing seat 220 and the adjusting rod 210 are both made of plastic. The first telescopic section 200 , the second telescopic section 300 or the third telescopic section 400 made of plastic has the advantages of light weight and low cost.
[0052] In some embodiments of the present invention, a guide slider 230 is provided on the ring side of the adjusting rod 210, and the fixing seat 220 is provided with a guide slot 240 adapted to the sliding of the guide slider 230, and the guide slot 240 is in an internally closed state.
[0053] In the above embodiment, the cooperation between the guide slider 230 and the guide slot 240 stabilizes the relative sliding of the adjustment rod 210 and the fixing seat 220, thereby preventing the adjustment rod 210 from rotating when sliding relative to the fixing seat 220. The guide slot 240 is internally closed, that is, the end of the guide slot 240 does not pass through the outside of the first notch, thereby preventing the adjustment rod 210 from slipping out of the first notch.
[0054] Optionally, the guide slider 230 and the guide slot 240 constitute a sliding guide structure, and the number of the above-mentioned sliding guide structures is multiple groups. The multiple groups of sliding guide structures further improve the stability of the relative sliding between the adjustment rod 210 and the fixing seat 220.
[0055] In some embodiments of the present invention, the first notch is provided with a first friction layer 250 , and the first friction layer 250 does not cover the guide groove 240 . The first friction layer 250 is used to abut against the ring side of the adjustment rod 210 .
[0056] In the above embodiment, the first friction layer 250 and the adjusting rod 210 are connected, so that after the adjusting rod 210 slides relative to the fixed seat 220, the adjusting rod 210 can remain stable under the friction resistance of the first friction layer 250, thereby ensuring the structural stability of the first telescopic section 200, the second telescopic section 300 and the third telescopic section 400 after the telescopic changes, and also making the use of the present device more stable.
[0057] The first friction layer 250 is made of friction material.
[0058] In some embodiments of the present invention, the clamping member 100 includes a base 103, a first arc-shaped elastic member 101 and a second arc-shaped elastic member 102. The first arc-shaped elastic member 101 and the second arc-shaped elastic member 102 are both arranged on the base 103. The opening of the first arc-shaped elastic member 101 and the opening of the second arc-shaped elastic member 102 are docked to form a clamping opening.
[0059] In the above embodiment, the first curved elastic member 101 and the second curved elastic member 102 are joined to form a circular clamping opening, which can securely clamp the patient's implant. Furthermore, because both the first curved elastic member 101 and the second curved elastic member 102 are elastic, the size of the clamping opening can be adjusted to accommodate implants of varying diameters, thus expanding its applicability.
[0060] In some embodiments of the present invention, the base 103 is movably provided with a positioning shell 700 that is clamped and matched therewith. A spherical body 710 is rotatably provided in the clamping area between the base 103 and the positioning shell 700. When the positioning shell 700 is adjusted, the rotational resistance of the spherical body 710 increases or decreases.
[0061] The spherical body 710 is provided with a connecting rod, which passes through the outside of the positioning shell 700 and is connected to the first telescopic joint 200. The positioning shell 700 is provided with a through opening adapted to the rotation of the connecting rod.
[0062] In the above embodiment, the first telescopic joint 200, through the rotational adjustment of the spherical body 710, can achieve the angle adjustment of the first telescopic deformation component relative to the clamping member 100, thereby accommodating the bending changes of the first telescopic deformation component, allowing the device to more easily fit the patient's upper or lower jaw. In addition, because the positioning shell 700 restricts the spherical body 710, the first telescopic joint 200 will not wobble after rotation due to the presence of resistance, thereby improving its stability.
[0063] In some embodiments of the present invention, the base 103 is provided with a positioning cylinder 720 , the spherical body 710 is disposed in the positioning cylinder 720 , and a portion of the spherical body 710 protrudes from the positioning cylinder 720 ;
[0064] The positioning tube 720 is provided with an external thread, and the positioning shell 700 is provided with an internal thread adapted to the external thread.
[0065] In the above embodiment, the threaded cooperation between the positioning shell 700 and the positioning cylinder 720 can adjust the force exerted by the positioning shell 700 on the spherical body 710, thereby adjusting the rotational resistance of the spherical body 710 to suit different medical staff.
[0066] Specifically, the base 103 in the positioning cylinder 720 is provided with a notch, a part of the spherical body 710 is located in the notch, and a second friction layer 730 is provided in the notch to abut against the spherical body 710. Through the joint action of the second friction layer 730 and the positioning shell 700, the resistance adjustment of the spherical body 710 will be easier.
[0067] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
