Description

[0001] MAGNETICALLY MOUNTED IMPLANT ASSEMBLY

[0002] Technical Field

[0003] The invention relates to an implant mounting assembly which allows a magnetic screw assembly to be screwed into a dental prosthesis by the force of a magnetic field without the need for bonding, screwing or mechanical compression.

[0004] State of the Art

[0005] The materials placed in the tissue to restore a missing part of the human body and to restore aesthetics and function are called implants. Local or general chewing force losses caused by tooth loss can be eliminated with artificial teeth substituted with implant treatment. Implants used for this purpose are mounted to the jawbone by screwing. A metal part called abutment is placed on the implant. A dental prosthesis or bridge mounted on a dental implant is completed by placing the coating material on the abutment. This installation can be done with three different methods. In veneer-abutment mounting application in the most common local dental treatments, the veneer is mounted on the abutment by bonding method. In this case, the material used for bonding should not lose its properties in hot, cold, mouth pH, different chewing pressure, etc. In addition, adhesive does not offer a suitable solution for disassembly. In the second method, the screw mounting system, which is mostly used in complete palate applications, is applied. This method is used in complete jaw implant applications in cases such as bone resorption rather than local tooth loss. The third method is again a complete palate application and no screws are used in the veneer-abutment assembly. Instead of screwing, it is applied as a mechanical tight fit of the complete palate on the abutment. The quality of the assembly here consists entirely of physical compression.

[0006] In the current system, there are various articles, patents and utility model applications related to implant assemblies. Application number CN103083097A is related to the subject matter. The invention relates to a retention device for dental implantation, cheekbone implantation and repair of craniofacial defects. The invention aims to provide a novel implant holder that can better utilize the adjacent bone space with abundant bone mass, freely adjust the angle of the implant, thus avoiding the dangerous anatomical structure of the implant and increasing the safety of the implant. In the implant mounting phase, it is stated that the fastener can be a magnetic attachment. The use of a magnetic attachment is explained to have a holding tolerance against movements in the axial direction and thus provides a non-slip structure with high holding strength. In this way, it is stated that assembly / disassembly can be done quickly and easily for the user.

[0007] The application numbered US2023017829A1 in the known state of the art relates to a dental implant. Threaded surfaces are used for the integration of the implant and the implant is connected to the screw. Magnets are used for unidirectional mounting and a magnetic shock absorber is created. The magnets create a pulling force in the perpendicular direction and the part is assembled. However, in this type of assembly, magnetic disconnections may occur due to magnetic assembly.

[0008] Application CN212788745U in the known state of the art relates to a denture suitable for disassembly and assembly. A connecting groove is formed to match the base of the implant, and a plurality of fixing grooves are provided along its periphery, and springs are respectively passed through the fixing grooves. When removing the tooth, the user can easily and quickly remove it by pressing with the elastic force of the spring. The first magnetic ring and the second magnetic ring are in contact with the first magnetic block and the second magnetic block. This makes it difficult to remove the base and guarantees that the tooth does not fall out.

[0009] Application CN217118637U in the known state of the art relates to a dental implant. A rapid assembly and disassembly process is carried out between the implant and the magnetic coating. In this aspect, the special situation between the coating and the magnetic coupling appears to persist. The magnetic locking mechanism comprises a spring, a connection plate, a connection frame, a first fixing block, a second fixing block, a positive magnet and a negative magnet. Problems such as the complexity of the denture installation process and the waste of time and labor during disassembly are solved.

[0010] In the current system, the abutment used in dental implant applications is screwed onto the implant. The prosthetic tooth is glued or screwed onto the abutment. However, in this technique, the material used for bonding should not lose its properties in conditions such as heat, cold, oral pH, different chewing pressure. In addition, adhesive does not offer a suitable solution method in disassembly processes. Because the surface area on the abutment is important in the bonding method and axial or oblique forces are balanced according to the bonding quality. According to the chewing pressure, the problem of balancing the adhesive force against loads coming from all directions may arise. In the screwing method, there is a screwing hole on the prosthetic tooth. This hole is then covered with the prosthetic structure. Both of these methods are compulsory in terms of strength, ease of application and aesthetics. In addition, it is known that the current implant, abutment and prosthetic tooth combination is a rigid structure.

[0011] In conclusion, due to the above-mentioned drawbacks and the inadequacy of existing solutions, there is a need for an implant mounting assembly that can be easily assembled and disassembled without the use of gluing, screwing or mechanical compression.

[0012] Brief Description and Objects of the Invention

[0013] The invention relates to an implant coating which allows a magnetic screw assembly to be screwed into a dental prosthesis by magnetic field force without the need for bonding, screwing or mechanical compression.

[0014] The aim of the invention is to ensure that the abutment can be assembled and disassembled after implant assembly without the need for any gluing, screwing or mechanical bonding in order to assemble the abutment to the coating (prosthesis). For this purpose, a mounting assembly has been developed using magnetic N-pole magnet and S-pole magnet in the present invention. The said N-pole magnet and S-pole magnet can be moved with an external magnet. In this way, there is no need for any gluing, screwing or mechanical bonding process. In addition, the possible loss of adhesive properties in hot, cold, mouth pH degrees that may occur in adhesive abutment assembly, or the assembly restriction applied only in palate applications is eliminated. With the magnetic assembly assembly developed with the invention, the assembly / disassembly process is carried out quickly.

[0015] Another object of the invention is to ensure that any force on the prosthetic tooth can be suspended. For this purpose, a spring is used in the invention. The spring placed inside the implant is capable of suspending any force coming to the prosthetic tooth.

[0016] Another object of the invention is to provide a mounting assembly that can be applied locally without the need for a complete palate or mechanical compression mounting restriction. For this purpose, a mounting process can be realized by using N-pole and S-pole magnets.

[0017] Another object of the invention is to enable rapid assembly and disassembly. In the invention in question, since the N-pole and S-pole magnets can be easily moved by means of an external magnet, assembly and disassembly can be carried out quickly.

[0031] Detailed Description of the Invention

[0032] The invention relates to an implant mounting assembly which allows a magnetic screw assembly, which is magnetically triggered, to be screwed into a dental prosthesis by the force of a magnetic field without the need for bonding, screwing or mechanical compression.

[0033] N-pole magnet (4) inserted between the mounting assembly abutment (2) and the prosthesis mounting screw (6) described in the invention, which can be separated from the S-pole magnet (5) in the process of assembling the implant by means of an external magnet (8) and which can be combined with the S-pole magnet (5) in the process of disassembling the implant by means of an external magnet (8); S-pole magnet (5) placed between the abutment (2) and the prosthesis mounting screw (6), which can be separated from the N-pole magnet (4) during the assembly of the implant by means of an external magnet (8) and combined with the N-pole magnet (4) during the disassembly of the implant by means of an external magnet (8); a prosthesis mounting screw (6) which is positioned at the bottom of the prosthetic tooth (7) in contact with the N-pole magnet (4) and the S-pole magnet (5) so that the prosthetic tooth (7) can be placed on the implant (1), and an abutment (2) on which the spring (3) is threaded for insertion into the implant (1) and on which the N-pole magnet (4), the S-pole magnet (5) and the prosthesis mounting screw (6) are positioned. In the invention in question, firstly, a hole in the shape of the diameter required for the installation of the implant (1) is drilled in the jawbone as shown in Figure-1. Then, the implant (1) is placed in this hole. The N-pole magnet (4), S-pole magnet (5), prosthesis mounting screw (6) and abutment (2) are combined to form a separate mounting assembly. This assembly of N- pole magnet (4), S-pole magnet (5), prosthesis mounting screw (6) and abutment (2) is a magnetized prosthetic screw assembly because it contains N-pole magnet (4) and S-pole magnet (5).

[0034] In the invention in question, the abutment (2), N-pole magnet (4), S-pole magnet (5), prosthesis mounting screw (6) are placed on the implant (1) respectively. In other words, this assembly consisting of N-pole magnet (4), S-pole magnet (5), prosthesis assembly screw (6) and abutment (2) is placed on the spring (3) placed in the implant (1). This assembly is realized by screwing the abutment (2) to the implant (1) inside the assembly assembly consisting of N-pole magnet (4), S-pole magnet (5), prosthesis mounting screw (6) and abutment (2).

[0035] The assembly of the prosthetic tooth (7) moves under the magnetic effect of a magnet (8) other than the N-pole magnet (4) and S-pole magnet (5) in the assembly assembly assembly consisting of N-pole magnet (4), S-pole magnet (5), prosthesis assembly screw (6) and abutment (2), and thus the screwing process to the prosthetic tooth (7) is completed.

[0036] When the physician wants to disassemble the implant (1), he / she can use an external magnet (8) to move this assembly assembly consisting of N-pole magnet (4), S-pole magnet (5), prosthesis mounting screw (6) and abutment (2). In this way, the implant (1) can be removed.

[0037] Thanks to the assembly assembly developed with the invention in question, the implant (1), abutment (2) and prosthetic tooth (7) form a rigid structure. In the invention, any force on the prosthetic tooth (7) is suspended by means of the spring (3) placed in the implant (1). The spring (3) placed in the implant (1) provides force balance and reduces the force stress on the implant (1).
