Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dental implants, and in particular relates to an implant device for fixing artificial teeth. Background Art
[0002] Implant dentures are implants (artificial tooth roots) placed in the alveolar bone in the edentulous area of the mouth. After the implant is alive, a restoration is made on its upper end to complete the restoration of the implant denture. It can significantly improve the patient's chewing function and feel comfortable like real teeth. Many difficult clinical cases that are difficult to solve with conventional dentures can achieve satisfactory results through implant dentures. Fixed dentures are restorations that repair one or several missing teeth in the dentition. They are connected to the prepared abutment teeth or implants on both sides of the missing teeth by adhesives or fixing devices, thereby restoring the anatomical morphology and physiological function of the missing teeth. Since patients cannot take off and wear this restoration by themselves, it is simply called a fixed denture.
[0003] Existing fixed dentures are generally fixed by a threaded structure during installation. Since there is a large gap between the fixed denture and the gums, it is easy for food residues to enter between the denture and the gums, causing bad breath in the mouth. In addition, the denture cannot be disassembled and replaced after installation. There is no convenient means to replace the new denture. If it needs to be replaced, the original denture can only be broken to be removed. This method is likely to cause greater damage to the gums and alveolar bone, which is not conducive to the patient's health. Utility Model Content

After the clamping ring 4 returns to room temperature, the clamping ring 4 moves to the lower side of the connecting piece 2 and drives the denture 1 to move downward, thereby effectively reducing the gap between the denture 1 and the gums; after a hole is opened on the denture 1 above the connecting piece 2, the connecting piece 2 can be screwed out and the denture 1 can be conveniently disassembled. The clamping section 22 is a conical structure that is wide at the top and narrow at the bottom, and the clamping ring 4 is a tubular structure. The inner wall of the clamping ring 4 fits the outer side surface of the connecting clamping section 22. After being frozen, the clamping ring 4 is mounted on the outer side of the clamping section 22. When the clamping ring 4 returns to room temperature, the volume of the clamping ring 4 increases, and under the action of the inclined surface, it moves to the lower side of the connecting piece 2. The outer side of the clamping ring 4 is connected to the inner wall of the clamping groove 12. After the clamping ring 4 is frozen, the denture 1 is mounted on the outer side of the connecting piece 2 and the clamping ring 4. When the clamping ring 4 returns to room temperature, the volume of the clamping ring 4 increases, and under the action of the inclined surface, it moves toward the lower side of the connecting piece 2, thereby driving the outer denture 1 to move toward the direction of the gums, thereby reducing the gap between the denture 1 and the gums. The insertion groove 11 is a straight hole structure, and the insertion section 21 is a cylindrical structure. The diameter of the plug-in groove 11 is equal to the diameter of the bottom end of the clamping groove 12. The operator can open a through hole with a diameter not less than the clamping groove 12 on the denture 1 above the connecting piece 2, and then unscrew the connecting piece 2 from the implant nail 3, and remove it from the through hole to complete the disassembly of the denture 1.
