Telescope crown magnetic retainer connection device

Abstract

The invention belongs to a mouth medical technology, and in particular relates to a telescope crown magnetic retainer connection device. A center post core and an inner crown of a magnetic retainer movable denture and a telescopic crown easily drop in the mouth rehabilitation, a patient needs to repeatedly repair the center post core and the inner crown to cause that the inconvenience is brought for life and the paint of the patient is increased and the treatment cost is increased. The telescope crown magnetic retainer connection device comprises a movable denture (1), a magnet (2), an armature (6) and a center post core (7), wherein a residual root and crown which has no remarkable loosening is selected, and subjected to root canal therapy, the center post core (7) is made, and is placed in the residual root and crown (8), the top end of the center post core (7) is connected with a connecting rod (3), the other end of the connecting rod (3) is connected with an inner crown (4) of the telescopic crown, an outer crown (5) is arranged on the outer part of the inner crown (4), and an abutment tooth (9) is arranged in the inner crown (4). The telescope crown magnetic retainer connection device has the advantages that the service life of the magnetic retainer movable denture and the telescopic crown are prolonged, and the pain and the treatment cost of the patient are reduced.

Description

technical field [0001] The invention belongs to the oral medical technology, in particular to a telescopic crown magnetic retainer connected device. Background technique [0002] Oral removable denture magnetic retainer technology is to use the magnetic principle to set a central post core and a magnetic armature on the residual root and crown of the abutment tooth, and to set a magnet on the base plate of the removable denture. The armature and the magnet attract each other, thereby realizing the removable denture Fixation in the oral cavity. The magnetic retainer technology for removable dentures does not require the use of metal clasps. It has the advantages of avoiding damage to the abutment teeth by the clasps, simple removal and wearing, easy cleaning, and beautiful oral cavity. It has been applied in oral restoration. However, the disadvantage of the removable denture magnetic retention technology is that the center post and core glued in the gingiva is easy to fall ...

AI Technical Summary

Problems solved by technology

However, the disadvantage of the removable denture magnetic retention technology is that the central post core bonded in the gums is easy to fall off. When the central post core falls off, the removable denture has poor retention or cannot be fixed.

However, the disadvantages of telescopic crowns are: after a long time of use, the inner crown is easy to be bonded and fall off; The nucleus is easy to fall off and needs to be glued and fixed repeatedly, which seriously affects the repair effect

The application of removable denture magnetic retainer and telescopic crown at the same time in oral restoration of single-jaw teeth, the above-mentioned shortcomings will also appear, making patients repeatedly repair and stabilize removable dentures

Bring inconvenience to the life of the patient, increase the pain of the patient, and increase the cost of treatment
