Abstract
Description
Technical Field
[0001] This utility model belongs to the field of orthodontics, and more specifically, relates to a protective device for the mucosa around a micro-screw implant. Background Technology
[0002] Microscrew implant anchorage technology originated in the late 20th century and is a type of temporary skeletal anchorage technique. This technique involves implanting pure titanium screw-shaped implants, which have not undergone surface etching or sandblasting, into the alveolar bone. Retention is primarily achieved through the mechanical interlocking force between the implant and the bone tissue to meet the anchorage requirements of orthodontic treatment. With the continuous innovation and development of orthodontic technology and the increasing demands of patients for aesthetic and functional efficacy in orthodontic treatment, implant anchorage has been widely used in clinical orthodontic work. As an absolute anchorage device, microscrew implant anchorage provides orthodontists with excellent three-dimensional dentition control. Procedures that were previously difficult to achieve using traditional orthodontic appliances, such as distalization of the entire dentition, intrusion of elongated molars, and skeletal expansion in adults, can now be accomplished with microscrew implant anchorage, greatly expanding the boundaries of orthodontic treatment.
[0003] Microscrew implants are typically integrated screw-mounted structures consisting of an extraosseous head and an intraosseous body. The head is designed to fit the specialized screwdriver of the corresponding microscrew implant system and to hold the orthodontic force application device. The head structure of microscrew implants is often a rigid polygonal structure with a narrow neck, protruding from the oral mucosa. In clinical practice, some patients experience a foreign body sensation due to the head structure, and the head structure can scratch the contralateral mucosa or irritate the contralateral and surrounding mucosa, leading to chronic mucosal inflammation and hyperplasia. To address these issues, some microscrew implant anchorage systems optimize the head structure by increasing the curvature of the microscrew head to reduce acute mucosal trauma and chronic irritation caused by the polygonal structure. Clinicians may use flowing resin or rubber ligatures to wrap the screw head structure initially after microscrew implantation, and some patients may use orthodontic protective wax to temporarily wrap the microscrew head structure to reduce the foreign body sensation. However, the above-mentioned improvement methods all have drawbacks: First, systematically optimizing the head structure and iatrogenic protective operations cannot change the rigidity of the screw head, and cannot avoid chronic traumatic irritation caused by rigid foreign bodies protruding from the mucosa over a long period of time; second, patients find it difficult to implement iatrogenic protective measures themselves, and the long-term accumulation of food residue around the protective device is more likely to cause inflammation around the microscrews, and patients cannot replace the protective device themselves if it falls off; finally, orthodontic protective wax used by patients themselves has the disadvantage of easily falling off due to friction with mucosal movement when used to wrap the microscrews, requiring repeated replacement by the patient. In summary, there is currently a lack of an orthodontic microscrew implant mucosal protection device that combines flexible protection, is convenient for both doctors and patients to replace, has good retention, and is universally applicable to multiple systems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective device for the mucosa around microscrew implants. This protective device provides flexible protection for the mucosa around microscrew implants, can be easily replaced by both doctors and patients, and has the advantages of good retention and versatility across multiple systems, thus supporting the safe and comfortable use of implant anchorage.
[0005] To achieve the above objectives, this utility model provides a protective device for the mucosa surrounding a micro-screw implant, comprising:
[0006] A medical silicone cap has a spherical outer surface, and a medical silicone flap or orthodontic ligation rubber band is provided at the bottom of the medical silicone cap;
[0007] When the patient uses this protective device, the medical silicone cap has a cavity inside, the medical silicone flap is placed in the cavity, the medical silicone flap is used to cover the head and neck edge of the microscrew implant, and the cavity and the medical silicone cap are used to wrap around the upper edge of the head of the microscrew implant.
[0008] When the doctor uses this protective device, the bottom of the medical silicone cap is provided with the orthodontic ligation rubber band, which is used to fit around the head and neck edge of the micro-screw implant, and the medical silicone cap is used to wrap around the upper edge of the implant head.
[0009] Optionally, the medical silicone flap and the medical silicone cap are integrally molded structures.
[0010] Optionally, the medical silicone flap is disposed at the opening of the cavity, the opening of the medical silicone flap is centrally located, and a slit is provided on the outer periphery of the opening.
[0011] Optionally, the radial height of the medical silicone flap is greater than half the height of the medical silicone cap.
[0012] Optionally, the orthodontic ligation rubber band and the medical silicone cap are integrally molded.
[0013] Optionally, the radial dimension of the orthodontic ligation rubber band is smaller than the maximum radial dimension of the medical silicone cap.
[0014] This invention provides a protective device for the mucosa around a micro-screw implant, which has the following advantages:
[0015] 1. This protective device uses medical-grade flexible silicone material as the outer surface material of the medical silicone cap, avoiding mucosal irritation and trauma caused by direct contact between the rigid head structure of the orthodontic micro-screw implant and the oral mucosa.
[0016] 2. When the protective device is a combination of a medical silicone cap and an orthodontic ligation rubber band, it is only suitable for use by doctors. It uses the elasticity of the rubber ligation ring commonly used in orthodontic clinical practice to fix the neck structure of the micro-screw implant, without any additional technical operation difficulty.
[0017] 3. When the protective device adopts the combination of medical silicone cap and medical silicone flap, it is suitable for patient use. Patients can operate it themselves without any obstacles. While it is beneficial for patients to maintain the hygiene around the implant, the protective sleeve, combined with the mechanical fixation of the silicone flap and the cavity negative pressure fixation, can ensure that the protective device is fixed in place for a long time.
[0018] 4. This protective device is fitted onto the head of the microscrew implant after the microscrew implant is inserted. This protective device can be used in the entire orthodontic process after microscrew implant anchorage and will not affect any orthodontic-related operations using microscrew implant anchorage.

[0025] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0026] This invention provides a protective device for the mucosa surrounding a micro-screw implant, comprising:
[0027] The medical silicone cap has a spherical shape, and the bottom of the medical silicone cap is equipped with a medical silicone flap or an orthodontic ligation rubber band.
[0028] When the patient uses this protective device, the medical silicone cap has a cavity inside, and the medical silicone flap is placed in the cavity. The medical silicone flap is used to cover the head and neck edge of the microscrew implant, and the cavity and the medical silicone cap are used to wrap around the upper edge of the head of the microscrew implant.
[0029] When doctors use this protective device, the bottom of the medical silicone cap is fitted with an orthodontic ligation rubber band, which is used to fit around the head and neck edge of the micro-screw implant, while the medical silicone cap is used to wrap around the upper edge of the implant head.
[0030] Specifically, the external structure of this protective device uses a medical-grade silicone cap, which reduces the irritation and trauma to the oral mucosa caused by the rigid head structure. For patient self-use, a medical-grade silicone flap needs to be placed at the bottom of the medical-grade silicone cap, and a cavity is created within the cap. Simply press the medical-grade silicone cap onto the microscrew implant, and the silicone flap will securely hold it against the neck structure of the microscrew implant. Because the upper edge of the microscrew implant head enters the cavity, air inside the cavity is expelled, achieving a dual fixation method of negative pressure fixation and mechanical fixation. Without professional medical guidance, patients can easily and securely install the protective device on the microscrew implant. The upper silicone cap structure wraps around the upper edge of the microscrew implant head, providing mucosal protection. When removing the device, the patient needs to gently pinch the silicone cap to remove it. For the doctor-use version, an orthodontic ligation rubber band needs to be placed at the bottom of the medical silicone cap. The doctor can use a needle holder to hold the orthodontic rubber band and place it on the neck structure of the microscrew implant head. The orthodontic rubber band elastically recovers and tightens on the neck structure of the microscrew implant. The elastic medical silicone cap covers the upper edge of the microscrew implant head. When removing it, the doctor needs to use a probe or needle holder to clamp or hook the orthodontic ligation rubber band off the microscrew implant.
[0031] Optionally, the medical silicone flap and the medical silicone cap are integrally molded structures.
[0032] Optionally, the medical silicone flap is placed at the opening of the cavity, with the opening of the medical silicone flap centered and a slit provided around the periphery of the opening.
[0033] Specifically, the bottom surface of the cavity of the medical silicone cap is connected to the outside of the silicone cap. Therefore, the opening of the cavity is located on the bottom surface of the medical silicone cap. The medical silicone flap is placed on the bottom surface of the medical silicone cap to achieve partial sealing of the cavity. An opening and a slit are formed on the medical silicone flap. The opening is used to avoid the head of the micro-screw implant, and the slit allows the opening to expand and contract. The opening and slit are a mutually cooperating structure. When the patient uses this protective device to install the micro-screw implant, the patient presses the protective device towards the head of the micro-screw implant. The opening of the medical silicone flap and the head of the micro-screw implant move closer together. Then, due to the silicone material of the flap, the slit automatically opens under the pressure of the patient's pressure. This allows the opening of the medical silicone flap to be larger than the cross-section of the head of the micro-screw implant. During the downward pressure of the protective device, air inside the cavity is also expelled through the opening, thus completing the installation of the protective device. The patient does not need much force to install it. When the medical silicone flap is positioned at the neck edge of the micro-screw implant head, the opening of the medical silicone flap matches the size of the head and neck edge. This closes the opening, sealing the cavity, and the upper edge of the micro-screw implant head fills the cavity, simultaneously creating a vacuum inside the cavity. This creates a dual retention force combining the mechanical fixation of the silicone flap and the negative pressure fixation of the cavity, achieving the effect of a doctor installing a medical-grade protective device without the need for any medical instruments.
[0034] Optionally, the radial height of the medical silicone flap is greater than half the height of the medical silicone cap.
[0035] Specifically, the medical silicone flap and the medical silicone cap are connected as a single unit to form a protective device. Since the medical silicone flap is located at the bottom of the cavity of the medical silicone cap, the opening for fitting the micro-screw implant is also located on the medical silicone flap. Thus, when installing the protective device on the micro-screw implant, only the top of the medical silicone cap needs to be pressed, and the opening can be fitted onto the micro-screw implant. When the micro-screw implant enters the cavity, the internal air is expelled, creating a negative pressure inside. Furthermore, the protective device will not wobble up and down when fitted onto the micro-screw implant.
[0036] Optionally, the orthodontic ligation rubber band and the medical silicone cap are integrally molded.
[0037] Optionally, the radial dimension of the orthodontic ligation rubber band is smaller than the maximum radial dimension of the medical silicone cap.
[0038] Specifically, the orthodontic ligation rubber band and medical silicone cap are connected as a single unit to form a protective device. It can only be fixed to the neck structure of the microscrew implant by fitting the rubber band. The size of the rubber band needs to be smaller than the size of the upper structure of the microscrew implant. During installation, the size of the rubber band is enlarged by a needle holder and then fitted onto the microscrew implant. The rubber band is then secured to the outer periphery of the neck structure by its own elastic contraction. During removal, the rubber band is clamped or hooked and deformed by a needle holder or probe to separate it from the microscrew implant.
[0039] This protective device is installed after the microscrew implant is fixed in the oral cavity. A medical silicone flap or orthodontic ligation rubber band is placed over the head of the microscrew implant. Since the head of the microscrew implant consists of a large-diameter implant superstructure and a small-diameter implant neck structure, the elastic deformation characteristics of the medical silicone flap and the orthodontic ligation rubber band allow the flap or rubber band to be placed over the small-diameter neck. The large-diameter implant superstructure then holds the flap or rubber band in place, preventing the protective device from falling off the microscrew implant.
[0040] Example 1
[0041] like Figure 1 As shown, this utility model provides a protective device for the mucosa around a micro-screw implant, comprising:
[0042] The medical silicone cap 1 has a spherical outer surface. A medical silicone flap 2 is provided at the bottom of the medical silicone cap 1. A cavity 3 is opened inside the medical silicone cap 1. The cavity 3 is used to wrap the head 6 of the micro-screw implant.
[0043] In this embodiment, the medical silicone flap 2 and the medical silicone cap 1 are integrally molded structures.
[0044] In this embodiment, the medical silicone flap 2 is placed at the bottom opening of the cavity 3, the opening 5 of the medical silicone flap 2 is centrally located, and a slit is provided on the outer periphery of the opening 5 to facilitate the opening of the medical silicone flap 2 to pass through the upper edge 7 of the head of the micro-screw implant.
[0045] In this embodiment, the radial height of the medical silicone flap 2 is greater than half the height of the medical silicone cap 1.
[0046] When the protective device for the mucosa around the micro-screw implant is used together with the micro-screw implant 4, the mucosa protective device for the micro-screw implant is detachably connected to the micro-screw implant 4.
[0047] In this embodiment, the micro-screw implant head 6 includes an upper edge 7 and a neck edge 8, and the cross-sectional area of the neck edge 8 is smaller than that of the upper edge 7.
[0048] In this embodiment, the medical silicone flap 2 is attached to the outer periphery of the head and neck edge 8 of the microscrew implant.
[0049] In summary, the connection method of this microscrew implant is as follows: After the patient uses their fingertips to pick up the slightly sticky medical silicone cap 1, they align the opening 5 of the medical silicone flap 2 with the head of the implant 4, gently press it against the head 6 of the microscrew implant, and simultaneously expel air from the cavity 3, allowing the medical silicone flap 2 to be secured to the neck edge 8 of the microscrew implant head. This provides continuous protection for the mucosa around the implant head during the retention of the medical silicone cap 1. When the patient needs to remove it, they simply need to hold the silicone cap 1 with two fingers and gently pull it off the implant 4.
[0050] Example 2
[0051] like Figure 2 As shown, this utility model provides a protective device for the mucosa around a micro-screw implant, comprising:
[0052] The medical silicone cap 1 has a spherical surface. The bottom of the medical silicone cap 1 is provided with an orthodontic ligation rubber band 9, which is used to fit over the head of the implant 4.
[0053] In this embodiment, the orthodontic ligation rubber band 9 and the medical silicone cap 1 are integrally molded structures.
[0054] In this embodiment, the radial dimension of the orthodontic ligation rubber band 9 is smaller than the maximum radial dimension of the medical silicone cap 1.
[0055] When the protective device for the mucosa around the micro-screw implant is used together with the micro-screw implant 4, the mucosa protective device for the micro-screw implant is detachably connected to the micro-screw implant 4.
[0056] In this embodiment, the micro-screw implant head 6 includes an upper edge 7 and a neck edge 8, and the cross-sectional area of the neck edge 8 is smaller than that of the upper edge 7.
[0057] In this embodiment, the orthodontic ligation rubber band 9 is attached to the outer periphery of the head and neck edge 8 of the microscrew implant.
[0058] In summary, the connection method of this micro-screw implant is as follows: After the doctor holds the orthodontic ligation rubber band 9 with a needle, the orthodontic ligation rubber band 9 is fixed to the neck edge 8 of the micro-screw implant head. During the fixation period with the elastic medical silicone cap 1, it can provide continuous protection for the mucosa surrounding the implant 4. When the doctor needs to remove it, the orthodontic ligation rubber band 9 can be dislocated from the implant 4 by holding or gently hooking it with a needle or probe.
[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
