Description

Technical Field

[0001] The utility model relates to the technical field of implants, in particular to a stabilizing device for immediate auxiliary retention of implants. Background Art

[0002] Currently, there are usually three main steps in implant restoration treatment for patients with edentulous arches in the aesthetic zone: a primary surgery to implant the implant; a secondary surgery 3-6 months after implantation to expose the implant sealing screw and replace it with a healing abutment to heal and shape the soft tissue around the implant; after the soft tissue shaping has stabilized for 3-6 months, a mold is taken and a permanent restoration abutment and crown restoration are made, which are installed and fixed on the implant in the patient's mouth to complete the implant restoration treatment process.

[0003] After clinical verification and with the deepening of clinical application and research, people have found that the implant restoration process has the following defects:

[0004] 1. After the implant surgery, clinicians usually need to place a healing abutment immediately. The stabilizing force of the conventional healing abutment comes from the implant, and it will cause external force interference to the implant to a large extent, so the implant will be displaced to a certain extent. At the same time, due to the increased displacement of the implant, the initial stability will decrease, resulting in a further increase in the time for the implant to integrate with the bone, thus prolonging the patient's consultation time.

[0005] 2. After the patient undergoes implant surgery, the soft tissue and implant bone integration need to go through a period of recovery and growth, so that the final restoration can satisfy the patient's corresponding chewing function and the aesthetic effect of the front teeth. During the healing period, the missing teeth in the mouth of some patients have greatly affected their daily social activities, especially the missing teeth in the front teeth area, which greatly increases the psychological burden of the patients, is not conducive to the physical and mental health of the patients, and brings patients a bad implant restoration experience. At this time, the immediate load-bearing implant restoration method came into being, that is, after the implant is implanted, the missing teeth are immediately repaired or the missing teeth are repaired before the postoperative bone integration to bear the load, which can achieve the effect of reducing the number of operations. However, early implant implantation is more likely to produce micro-movement, and the stress of the implant-bone integration interface increases. In this case, the success rate of immediate load-bearing implant restoration drops sharply. In severe cases, it will cause the implant to loosen and cause the implant to fail.

[0006] 3. Clinicians usually extract the diseased tooth and implant an implant. During the subsequent recovery process of the periodontal soft tissue, the soft tissue may enter the extraction socket, greatly affecting the bone regeneration around the implant, which in turn becomes the main factor in the failure of implant restoration.

[0007] 4. When using a repair abutment, the gap between the abutment and the soft tissue is more prone to infection, thus increasing the incidence of peri-implantitis. Peri-implantitis can lead to marginal bone resorption and infection of the implant, eventually causing the implant to loosen and fall off, resulting in implant failure.

[0008] In view of the above defects in the prior art, a stabilizing device for immediate auxiliary retention of an implant is provided. Utility Model Content

[0009] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a stabilizing device for immediate auxiliary retention of an implant, which solves the problems of displacement and infection in implant restoration.

[0010] The technical solution is a stabilizing device for immediate auxiliary retention of implants, including a device body, wherein the device body includes a shielding structure, an embedded structure, a repair structure and a connecting structure, wherein the repair structure is a columnar structure, the shielding structure extends outward from the top of the repair structure and is concavely formed, the edge of the shielding structure forms an embedded structure in a pointed state, and the connecting structure is arranged at the bottom of the device body.

[0011] The shielding structure mainly functions to close the opening of the extraction socket, shield the soft tissue, and facilitate bone formation around the implant. The diameter of the structure is set according to the neck of the tooth root, which is usually larger than the diameter of the extraction socket, so as to achieve the effect of closing the extraction socket; when in use, the embedded structure can contact the marginal bone around the implant to achieve the effect of mechanical connection; the device body cooperates with the structure to enable the healing base itself to generate a stabilizing force, thereby reducing the external force interference from the healing base to the implant; the embedded structure is embedded in the bone around the implant, providing mechanical retention force for the implant from the early stage of implantation to the completion of bone integration, reducing the micro-movement of the implant and providing a more stable environment for bone integration; the height size of the repair structure is selected according to the height of the bone defect around the implant when in use, to avoid excessive bone defects at the missing tooth position, which may cause the emergence of unstable factors when the implant is implanted too deeply, and is conducive to the formation of bone height; the connection structure selects an implant interface according to different application scenarios, and the structure is an integrated structure after connection.

[0012] Furthermore, the connecting structure includes a tapered structure and a threaded structure, the threaded structure is located at the lower part of the tapered structure, a through-gingival structure is arranged above the embedded structure, a wrench slot structure is arranged in the device body, the through-gingival structure is a cylindrical structure, and the wrench slot structure is located at the top center axis position of the device body, and is an inward-concave regular polygonal structure.

[0013] Furthermore, the connecting structure includes a tapered structure and a threaded structure, the threaded structure is located at the lower part of the tapered structure, the upper surface of the shielding structure forms an arc-shaped soft tissue shielding structure, and a wrench slot structure is arranged in the device body, the wrench slot structure is located at the top center axis position of the device body, and is a concave regular polygon structure.

[0014] Furthermore, the connection structure includes a tapered structure and an anti-rotation structure, the anti-rotation structure is arranged below the tapered structure, the transgingival structure is arranged above the embedded structure, a scanning structure with multiple concave and convex blocks is arranged above the transgingival structure, and a central bolt channel is arranged in the device body.

[0015] Furthermore, the connection structure includes a tapered structure, an arc-shaped soft tissue shielding structure is formed on the upper surface of the shielding structure, a retaining structure is arranged above the shielding structure, and a plurality of annular groove structures are arranged on the surface of the retaining structure.

[0016] Furthermore, a central bolt structure is arranged in the middle of the device body.

[0017] Furthermore, a central bolt structure is arranged in the middle of the device body, and a non-resistance structure is arranged below the tapered structure, and the non-resistance structure is a cylindrical design that can realize 360° rotation.

[0018] Furthermore, a threaded structure is arranged below the tapered structure, and a transgingival structure is arranged between the shielding structure and the retaining structure.

[0019] Furthermore, a central bolt structure is provided in the middle of the device body, a non-resistance structure is provided below the tapered structure, the non-resistance structure is a cylindrical design for achieving 360° rotation, and a transgingival structure is provided between the shielding structure and the retention structure.

[0020] Furthermore, a turning structure is arranged between the retaining structure and the transgingival structure to form an inclined angle between the retaining structure and the transgingival structure.

[0021] The functions of each component are as follows: when the tapered structure is connected to the inside of the implant, a sealing effect is achieved to prevent microorganisms or bacteria from entering the implant from here.

[0022] The threaded structure can realize threaded fastening connection between the device body and the implant, and the structure can be selected to form an integrated structural form according to different application scenarios.

[0023] The structure in which the transgingival structure is connected to the top edge line of the gums achieves the shaping and supporting effects of the gum soft tissue during the healing period, thereby achieving the aesthetic effect of implant restoration of the gums.

[0024] The wrench slot structure is located at the top center axis of the device body to achieve an anti-rotation effect. When used with a clinical surgical tool, namely a torque wrench, the device body can be smoothly screwed into the implant.

[0025] The soft tissue shielding structure shields the infection source from the gap between the base and the soft tissue, effectively reducing the probability of peri-implantitis and the bone damage to the neck of the implant caused by the infection source outside the joint.

[0026] The anti-rotation structure is consistent with the internal structure of the implant and achieves an anti-rotation effect; the position and direction of the device body can be determined by the anti-rotation structure.

[0027] The scanning structure is a structure with various height difference surfaces such as grooves, protrusions and planes, which corresponds to the position of the anti-rotation structure at the bottom; clinicians can use the scanning structure in conjunction with an intraoral scanner to obtain the direction, angle and position of the anti-rotation structure, thereby further obtaining data information such as the direction, angle and position of the implant, which is a key factor in the success of implant restoration.

[0028] The central bolt channel uses the central bolt corresponding to the implant system, and through this structure, the device body is fastened and connected with the internal thread of the implant.

[0029] The non-resistance structure is consistent with the inscribed circle of the internal structure of the implant and realizes a 360° rotation effect; by adjusting the direction of the device body through the non-resistance structure, the clinical application can be more extensive and the operation can be more convenient; according to different application scenarios, the structure is selected to form an integrated structural form.

[0030] The multiple annular groove structures on the surface of the retention structure are arranged in an axial array, which can increase the contact area and enhance the retention ability when bonding with the artificial denture; at the same time, the retention structure body also has parallel surfaces and is symmetrically arranged, which can achieve anti-rotation ability when bonding with the artificial denture, making the connection position more secure; according to the application of this structure, the device body is suitable for immediate load-bearing restoration of the implant, shortening the patient's chairside time, solving the patient's discomfort due to missing teeth, and can restore the patient's chewing function and the beauty of the front teeth at an early stage. It is an important component of immediate load-bearing implants.

[0031] The corner structure can solve the problem of inconsistency between the implantation angle and the curvature of the dentition; and can repair the implantation angle within the range of 10°-45°.

[0032] At the same time, this patented technology also provides the use of the repair type stabilization device:

[0033] A. First, the clinician needs to plan according to the bone condition of the patient's alveolar bone and the specific location of the missing part, and make good preparations before implantation, and then implant the implant into the patient's alveolar bone;

[0034] B. Before using the device, you need to confirm the packaging, sterilization and other conditions to ensure that they meet the surgical requirements;

[0035] C. The assistant nurse is responsible for opening the outer packaging of the device, and placing the device gently on the sterile operating table without touching or contaminating the device.

[0036] D. The clinician places the device body in the corresponding structure of the implant and adjusts the position of the device body to be consistent with the curvature of the patient's dentition;

[0037] E. Then connect the torque wrench with the implant handpiece at one end to the central bolt wrench slot and connect it to the corresponding structure of the implant through the central bolt channel 1148 of the device body;
