Description

Technical Field

[0001] The utility model relates to the technical field of dental treatment, in particular to a false tooth that is prevented from loosening. Background Art

[0002] Dental implant technology is currently the most respected method for restoring missing teeth in the oral medicine field. It achieves the purpose of restoring missing teeth by implanting artificial tooth roots in the alveolar bone and then installing porcelain teeth. Compared with traditional dental bridges and removable dentures, dental implants have higher stability, comfort and similarity, allowing patients to enjoy the chewing power and pronunciation effects of real teeth even when they are missing teeth.

[0003] However, in the prior art, the connection between the artificial tooth root and the porcelain tooth is usually fixed by bonding, which makes it easy for the connection between the artificial tooth root and the porcelain tooth to break during long-term use, resulting in the defect of a loose connection between the porcelain tooth.

[0004] Based on this, the utility model designs a false tooth that prevents loosening to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a false tooth that prevents loosening, so as to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising an implant and a dental crown, the implant being provided with a clearance hole, the clearance hole being provided with a clearance groove, a connecting rod being slidably arranged in the clearance hole, and a magnetic limit block being fixedly arranged at one end of the connecting rod away from the implant; a base being fixedly arranged on the dental crown, the base being provided with a clearance through hole, and the clearance through hole being provided with a limit groove; a resistance piece being fixedly arranged in the clearance groove, the other end of the resistance piece being tightly pressed against the limit groove, a connecting piece being fixedly arranged on the connecting rod, and the other end of the connecting piece being fixedly arranged on the resistance piece.

[0007] Preferably, a guide platform is fixedly provided on the implant, a guide groove is provided on the base, and the guide platform is slidably provided in the guide groove.

[0008] Preferably, two of the give-way grooves are provided, and the two give-way grooves are located on two opposite sides of the give-way hole; and two of the limit grooves are provided, and the two limit grooves are located on two opposite sides of the give-way through hole.

[0009] Preferably, a viscous sealing material is filled between the implant and the matrix.

[0010] In summary, the present application has the following beneficial technical effects: through the setting of the interference piece, when the crown is installed, after the base is installed at the predetermined position of the implant, the interference piece on the implant will be tightly pressed in the limiting groove, so that the base is fixed on the implant, which has the advantage of firm installation.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The following is combined with Figure 1 —4 Provide further details of this application.

[0020] A false tooth that prevents loosening comprises an implant 1 and a crown 2.

[0021] The implant 1 is provided with a clearance hole 3 , in which a clearance groove 4 is provided. There are two clearance grooves 4 , and the two clearance grooves 4 are located on two opposite sides of the clearance hole 3 .

[0022] A connecting rod 5 is slidably arranged in the clearance hole 3 , and a magnetic limiting block 6 is fixedly arranged at one end of the connecting rod 5 away from the implant 1 .

[0023] A base 7 is fixedly provided on the crown 2 , a through hole 8 is provided on the base 7 , a limiting groove 9 is provided in the through hole 8 , and two limiting grooves 9 are provided, and the two limiting grooves 9 are located on two opposite sides of the through hole 8 .

[0024] A resisting piece 10 is fixedly arranged in the yielding groove 4 , and the other end of the resisting piece 10 is tightly pressed against the limiting groove 9 . A connecting piece 11 is fixedly arranged on the connecting rod 5 , and the other end of the connecting piece 11 is fixedly arranged on the resisting piece 10 .

[0025] A guide platform 12 is fixedly arranged on the implant 1 , a guide groove 13 is provided on the base 7 , and the guide platform 12 is slidably arranged in the guide groove 13 ; a viscous sealing material 14 is filled between the implant 1 and the base 7 .

[0026] The implementation principle of this embodiment is as follows: when the denture needs to be installed, the implant 1 is first implanted into the alveolar bone, and then the clearance hole 8 is set on the implant 1, and the base 7 is moved closer to the implant 1; when the base 7 is moved closer to the implant 1, the guide groove 13 squeezes the contact piece 10, so that the two contact pieces 10 are close to each other, and the two connecting pieces 11 pull the connecting rod 5 downward until the contact piece 10 is separated from the contact of the guide groove 13, and the contact piece 10 rebounds and contacts in the limiting groove 9, and the two connecting pieces 11 drive the connecting rod 5 to rise; finally, the guide of the guide platform 12 and the guide groove 13 The base 7 is installed on the implant 1, and the viscous sealing material 14 is filled between the base 7 and the implant 1 to complete the installation of the denture; when the denture needs to be disassembled, the external magnetic device is placed above the crown 2, so that the magnetic poles generated by the external magnetic device and the magnetic limit block 6 repel each other. At this time, the connecting rod 5 is acted upon by the magnetic limit block 6 and moves toward the implant 1. The contact piece 10 is acted upon by the connecting piece 11 connected to the connecting rod 5, and the two contact pieces 10 approach each other and break away from the contact with the limit groove 9, so that the base 7 can be removed from the implant 1, completing the disassembly of the denture.

[0027] By setting the abutment piece 10, when installing the crown 2, after the base 7 is installed at the predetermined position of the implant 1, the abutment piece 10 on the implant 1 will be tightly pressed against the limiting groove 9, so that the base 7 is fixed on the implant 1, which has the advantage of firm installation.
