Abstract

The utility model discloses a seam welding no-skid magnetic attachment. The technical design is that two permanent magnets of same size with mutual attraction are sealed by two stainless sleeves through seam welding. One pole of the magnet is covered by concentrating flux steel sleeve, and the other pole attracts armature iron. The armature iron has two sides, one side is smooth and the other side is arranged with bulge anti-slip bar. The utility model prevents dislocation by the protruded anti-slip line on the armature iron, and expands the clinical application of magnetic attachment from magnetic overdenture to precision attachment uses. This design will make patients who are reluctant to cut teeth accept treatment more easily. The support board for armature iron can be either cast at the distal occlusal of ceramic crown or the distal occlusal of the teeth. The utility model has the advantages of simple structure, easy welding and operation, strong anti-erosion capability and stable retention force, Easy handling, inexpensive, extensive applications, all of which pave the way for this magnetic attachment to be popularized at grassroots levels.

Description

Seam welding anti-slop serrations section magnetic retention attachment

Technical field

This utility model relates to a kind of dentistry fixing device, and especially a kind of being specially adapted to protects the residue abutment and manufacture removable denture, the ideal simple fixing device of employing at the serious dental caries of tooth bad, when disappearance.

Background technology

Nineteen eighty-three, China studied successful Nd-Fe-B permanent magnet first, had promoted the development of dentistry magnetic attachment greatly; Become the commodity listing to Denture attachment in 1993.Day by day extensively pay attention in the world over past ten years using the magnetic retention attachment to do removable denture, it is simple to operate, and maintenance power is strong, and get and wear conveniently, favourable health of base tooth, it is old and feeble to delay face, welcome by old odontopathy patient.

Though China is the invention state and the big producing country of Nd-Fe-B permanent magnet, the neodymium iron boron of producing is very cheap, but the magnetic attachment of dental applications is mostly from Japanese import, very expensive with the laser weld price, a lot of patients are not with rising, and magnetic fixed body range of application is also very narrow, can only do the topped tooth of magnetic, for vast odontopathy patient's health, so essential production is a kind of cheap, broad-spectrum magnetic attachment.

Summary of the invention

It is strong, simple to operate that the purpose of this utility model provides a kind of maintenance power, gets and wear conveniently, cheap, broad-spectrum magnetic retention attachment.

This utility model principle:

Armature is a kind of can attraction by magnet steel, as the rustless steel of ferrum.Armature is fixed on the root post of root of the tooth or implantation body, or be fixed on the abutment distal surface or the casting at the porcelain facies distalis dentis, held by the magnetic retention attachment on the artificial tooth, just can play the maintenance effect, itself does not have magnetic armature, but can be held by magnetic attachment.

Technical solution adopted in the utility model is: two lobe stainless steel sleeves seal up two onesize permanent magnets of attracting each other by seam welding, and a utmost point of permanent magnet covers with the magnetic conduction steel bushing, and another utmost point attracts armature; Armature divides the two sides, and one-sided smooth, one side are established a tread plate that protrudes.

This utility model is owing to established the non-skid thread of a projection on armature, can prevent to dislocate with sliding type, thereby enlarged the clinical application range of magnetic retention attachment, the topped artificial tooth of magnetic is done in decapacitation, can also do other precision attachment, the patient who makes some be reluctant to cut off tooth is acceptant, and the armature gripper shoe can be cast at the distal surface of ceramic crown or is bonded at the distal surface of tooth.

This utility model is simple in structure, easily welding, and easy to operate, anti-corrosion capability is strong, and maintenance power is stable, and get and wear conveniently, low cost, applied range is a kind of accurate tooth section magnetic retention attachment that can popularize in basic unit.

The specific embodiment

This novel magnet such as Fig. 1 are made up of two blocks of neodymium iron boron permanent-magnet steels of attracting each other 1,4, by the stainless steel sleeve 3,5 of two lobes as straw hat this magnet steel are sealed, and seam welding welding is convenient at roomy edge, plays sealing function.Fig. 2 cuts away unnecessary big limit for after seam welding, only stays a bit little limit 6.Fig. 3 is after 6 bendings of little limit, covers a rustless steel magnetism-guiding hood 2 again in the upper end of magnet, plays the effect of the shielding magnetic line of force.Fig. 4 promptly is the suction surface of armature 7 gripper shoes for the lower end of Magnet.Magnet is placed on the removable denture, can influence electromagnetic information because of wearing artificial tooth, taking off removable denture can not influence the head magnetic resonance inspection.

This novel armature 7 is made by 1 chromium, 17 rustless steels, divides the two sides, and Fig. 6 shows that one side is a shiny surface, uses as the topped artificial tooth of common magnetic; Another meets personally Fig. 5, is provided with an edge tread plate 8, and tread plate 8 protrudes 0.2 millimeter than the plane, and is wide 0.3 millimeter, long 3 millimeters.Armature 7 is at roasting magnetic facies distalis dentis, and the edge tread plate 8 of protrusion prevents the mode slippage of magnetic attachment 9 to slide, thereby improves maintenance power.

Fig. 8 be armature casting or the distal surface that is bonded at tooth cooperate the clinical practice sketch map with magnetic attachment 9.

Fig. 9 is that armature and gripper shoe casting cooperate the clinical practice sketch map with magnetic attachment 9 on the root medicated cap.

Claims
