Description

Technical Field

[0001] The utility model relates to an oral orthodontic treatment device, in particular to an upper palate implant support device. Background Art

[0002] Implant anchorage devices are important devices in oral orthodontic treatment. Their function is to maximize the movement of the teeth that need to be corrected during orthodontic treatment, while preventing or controlling unwanted tooth movement through various methods, thereby achieving anchorage control.

[0003] The basic structure of the existing implant support device consists of a palatal micro-implant head connection structure and an extraoral connection rod structure, which needs to be bent and welded extraorally by a physician.

[0004] The current problem is:

[0005] Problem 1: The mushroom-shaped head of the micro-implant of the existing implant support device cannot be directly assembled with the connector, and the doctor can only bond the connector to the micro-implant with resin.

[0006] Question 2: Existing implant support devices are cumbersome to operate. During the resin bonding process, the patient needs to keep his mouth wide open. The doctor's operation takes a long time and the patient's discomfort is high.

[0007] Question 3: During the resin bonding process of existing implant support devices, resin overhangs will inevitably form, causing plaque retention, which is not conducive to maintaining oral hygiene for patients; the connector is large in size and uncomfortable for patients.

[0008] Question 4: The resin connection of existing implant support devices is unstable.

[0009] Question 5: Existing implant support devices often require the use of two or more micro-implants to increase support. The implantation position of the micro-implant in the anterior palate requires CT assistance and requires cumbersome personalized design. The complex morphology of the palatine vault makes it difficult to obtain a common positioning path when implanting multiple micro-implants, and assembly is even more difficult.

[0010] Question 6: The existing implant support devices, rubber chains, tension springs or ligatures only have traction sites at the two ends of the artificially bent connecting rod, and the traction method is single. For patients with special traction needs, cumbersome personalized designs are often required.

[0011] Question 7: With existing implant support devices, the palate mucosal tissue is relatively thick, and excessive mucosal proliferation is prone to occur after the micro-implant is implanted. At the same time, infection will further aggravate the proliferation of local mucosal tissue.

[0012] Question 8: Existing implant support devices can only be removed by grinding off the resin, which is time-consuming and labor-intensive, and there is a risk of damaging the patient's soft and hard tissues. Summary of the invention

[0013] The utility model aims to provide a palate implant support device, which is easy to install and operate and has high patient adaptability.

[0014] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0027] The utility model is further described below with specific embodiments:

[0028] This embodiment provides an upper palate implant support device, which is used for oral orthodontic treatment.

[0029] See also Figure 1 and Figure 2 The implant support device of this embodiment includes a support frame 1 and two micro-implants 2.

[0030] The support frame 1 is composed of two support wings 11. The two support wings 11 are in a "human" shape as a whole, which can also be said to be a bit like a "clothes rack" shape. This configuration is designed to match the shape of the upper palate in the oral cavity. For the convenience of description, this configuration is called "upper palate matching human shape".

[0031] Match the upper palate to the head end of the herringbone shape ( Figure 2 The area pointed by the arrow A in the middle is called the "front part of the palate".

[0032] Match the upper palate to the two sides of the herringbone shape ( Figure 2 The area indicated by the arrows B1 and B2 is called the "palatal side".

[0033] Two implant holes 13 are provided at the front end of the palate of the two wings 11 of the support. The two implant holes 13 are provided corresponding to the two micro-implants 2 mentioned above. The implant holes 13 are used for the micro-implants 2 to pass through the implant holes 13 and then be screwed into the double-layer bone cortex of the upper palate, thereby fixing the entire support frame 1 at the upper palate.

[0034] In this embodiment, Figure 2 In the orientation shown, the two implant holes 13 are symmetrically arranged at the front and rear sides of the front end of the palate of the two wings 11 of the support. For the convenience of description, this symmetrical arrangement is referred to as "front-rear symmetrical arrangement".

[0035] In particular, the planting hole 13 is arranged in a cone-shaped configuration.

[0036] Specifically, see Figure 1 ,

[0037] A cylindrical structure is provided at the planting hole 13 , and for the convenience of description, the cylindrical structure is referred to as a “central sleeve 15 ”; two central sleeves 15 are connected together by a connecting plate structure.

[0038] The central sleeve 15 is configured to have an inverted tapered configuration, or in other words, a configuration that converges inwardly.

[0039] The central sleeve 15 of the inverted taper configuration has a smooth surface and a certain taper design, and has good biocompatibility with the mucosal tissue of the palate. At the same time, the connecting plate structure is stepped with a height of 0.5 mm, and a 1.5 mm high gap is left at the bottom to accommodate possible hyperplasia of mucosal tissue and avoid reactive hyperplasia of palate mucosal tissue covering the tip of the micro-implant after micro-implant implantation.

[0040] It should be noted that, in another embodiment, Figure 3 As shown, the two implant holes 13 can also be arranged on the left and right sides of the front end of the palate of the two wings 11 of the support. For the convenience of description, this arrangement is referred to as a "left-right symmetrical arrangement";

[0041] For patients with fully developed palatal suture, the anterior-posterior symmetrical arrangement is selected, and the micro-implant is implanted at the horizontal part behind the palatal suture;

[0042] For patients with poorly developed midpalatal suture, a bilaterally symmetrical arrangement can be chosen, with appropriate implant sites selected on both sides of the midpalatal suture.

[0043] In addition, for patients with complex palatal vaults, personalized customization can be achieved through 3D software to select the most appropriate implant site.

[0044] In addition, a head end traction hook 12 is provided at the front end of the palate of the two wings 11 of the support. The head end traction hook 12 is in the shape of a hook with an upward opening facing backwards. The head end traction hook 12 can be used as a traction site for a rubber chain, a tension spring or a ligature wire. The upward angle of the head end traction hook 12 is designed to leave a certain distance from the palatal mucosal tissue to avoid compressing the palatal soft tissue. At the same time, the design of the opening facing backwards can prevent the front traction device from loosening.

[0045] In addition, a plurality of wing traction hooks 14 are provided on each palatal edge of the two wings 11 of the support, and the two wing traction hooks 14 can be used as traction sites of rubber chains, tension springs or ligature wires. Several designs can meet the orthodontic traction needs of different tooth positions and directions.

[0046] In this embodiment, the number of the two-wing traction hooks 14 disposed on each palatal side portion is five, while in other embodiments, the number of the two-wing traction hooks 14 can be set according to actual needs.

[0047] It should be noted that the two supporting wings 11 , the head end traction hook 12 , the implantation hole 13 and the two wing traction hooks 14 are integrally formed, thereby forming a complete supporting frame 1 .

[0048] See also Figure 4The micro-implant 2 adopts the structure of the prior art.

[0049] The micro-implant 2 is provided with a head portion 21 , a gingival portion 22 and a threaded portion 23 in sequence from top to bottom.

[0050] The head end portion 21 is configured in a hexahedral configuration, so that it is convenient to rotate the micro-implant 2 using a hexagonal wrench.

[0051] The surface of the gingival portion 22 is smooth, so that it can have better compatibility with the mucous membrane tissue of the palate.

[0052] The specific size and structure of the micro-implant 2 are determined according to the requirements of orthodontic treatment. The specific structure of the micro-implant 2 is known in the prior art and will not be described in detail.

[0053] The implant support device of this embodiment is installed as a whole in the upper palate of the human mouth. Its function can be summarized as maximally moving the teeth that need to be corrected during orthodontic treatment, while preventing or controlling unwanted tooth movement through various methods, thereby achieving support control.

[0054] The specific installation method of the implant support device in the upper palate of this embodiment is as follows:

[0055] The support frame 1 is placed on the upper palate, with the front end of the support frame 1 facing the front end of the upper palate. Two micro-implants 2 are passed through the two implant holes 13 of the support frame 1 and then screwed into the double-layer bone cortex of the upper palate, thereby fixing the two support wings 11, or in other words, the entire support frame 1, on the upper palate.

[0056] The implant support device of this embodiment has the advantages that:

[0057] The implant support device of this embodiment is integrally formed, and therefore does not require extraoral bending and welding, thereby solving Problem 1 mentioned in the background technology: "In existing implant support devices, the mushroom-shaped head of the micro-implant cannot be directly assembled with a connector, and the doctor can only bond the connecting device to the micro-implant with resin."

[0058] The implant support device of this embodiment has a central sleeve 15 structure fixed to the head end of the micro-implant through a mechanical structure, does not require resin bonding, and only needs to install one device, thereby solving the problem 2 mentioned in the background technology: "Existing implant support devices are cumbersome to operate. During the resin bonding process, the patient needs to keep his mouth wide open. The doctor's operation time is long, and the patient's discomfort is high."

[0059] The implant support device of this embodiment, due to its small integrated device size and precise structure, does not require resin bonding, thus solving the problem 3 mentioned in the background technology: "In the resin bonding process of existing implant support devices, resin overhangs will inevitably form, causing plaque retention, which is not conducive to maintaining the patient's oral hygiene. The connector is large in size and uncomfortable for the patient."

[0060] The implant support device of this embodiment has the central sleeve 15 The square diameter is smaller than the outer diameter of the hexagonal platform at the end of the micro-implant head, and the micro-implant is implanted in the double-layer cortical bone of the palate to achieve mechanical retention, thereby solving problem 4 mentioned in the background technology: the existing implant support device has an unstable resin connection.

[0061] The implant support device of this embodiment is implanted in the midpalatal suture (adults) and beside the midpalatal suture (adolescents). It has small individual differences and does not rely on CT positioning. The midpalatal suture and the area beside the midpalatal suture have sufficient bone tissue thickness support, and two micro-implants in the anterior-posterior or left-right directions can provide sufficient and stable support. The wings can be bent and adjusted according to the patient's palate morphology, which is suitable for most individuals and avoids cumbersome personalized design. Thereby solving the problem 5 mentioned in the background technology: the existing implant support devices often need to use more than two micro-implants to increase support. The implantation position of the micro-implant in the front of the palate requires CT assistance and cumbersome personalized design. The complex morphology of the palatal vault makes it difficult to obtain a common positioning path when implanting multiple micro-implants, and assembly is more difficult.

[0062] The implant support device of this embodiment realizes multi-directional traction, including a median traction hook, which realizes vertical and sagittal force application on the anterior and posterior teeth. The two wings of the support can be bent and adjusted according to the patient's palate morphology, which is suitable for most individuals and avoids cumbersome personalized design, thereby solving the problem 6 mentioned in the background technology: the traction sites of the existing implant support devices, rubber chains, tension springs or ligatures are only the two ends of the artificially bent connecting rods, and the traction method is single. For patients with special traction needs, cumbersome personalized design is often required.

[0063] In the implant support device of this embodiment, the micro-implant implantation site is designed as an inverted cone sleeve, which has little stimulation to the mucosa, good compatibility with the mucosa, and reduces the occurrence of hyperplasia and infection, thereby solving problem 7 mentioned in the background technology: in the existing implant support devices, the palatal mucosal tissue is thicker, and excessive mucosal hyperplasia is prone to occur after the micro-implant is implanted. At the same time, infection will further aggravate the hyperplasia of local mucosal tissue.

[0064] The implant support device of this embodiment can be removed by simply taking out the micro-implant through the implant handle and then simultaneously removing the support frame. The operation is safe and easy, thus solving Problem 8 mentioned in the background technology: the existing implant support devices can only be removed by grinding off the resin, which is time-consuming and labor-intensive, and there is a risk of damaging the patient's soft and hard tissues.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
