Abstract
The invention belongs to the magnetic retaining technology of an oral false tooth, and in particular relates to a magnetic retaining device for a false tooth connecting rod. In the prior art, a magnetic armature is fixedly arranged on a tooth or a single root of a residual root and a residual crown, so that the central post cores are not connected with each other. The defects are that for the abutment, the root of the tooth needs to be long and thick and the central post core needs to be long, and the false tooth is easy to fall. According to the magnetic retaining device for the false tooth connecting rod provided by the invention, metal central posts (1) are bonded on the residual root of the abutment and connected together through a metal connecting rod (2); 2-4 magnetic armatures (3) are arranged on the metal connecting rod (2); the false tooth (6) is arranged on a basic layer board (4); and 2-4 magnets (5) are arranged in positions of the lower part of the basic layer board (4) corresponding to the magnetic armatures (3) on the metal connecting rod (2). The magnetic retaining device for the false tooth connecting rod provided by the invention has the advantages that the requirement on the abutment is low, and the false tooth can be firmly fixed even if the root is short and loose; the false tooth is stable to retain, and the central post core is not easy to fall, so that the service life is prolonged; and the magnetic retaining device for the false tooth connecting rod is simple to pick and wear, easy to clean, and convenient and comfortable for patients to use.
Description
Technical field
The invention belongs to oral artificial tooth magnetic retention technology, specifically a kind of artificial tooth connecting rod magnetic retention device.
Background technology
Oral artificial tooth magnetic retention technology is to utilize magnetic principles at the abutment residual root armature keeper to be set, and at the base plate of artificial tooth Magnetitum is set, and armature and Magnetitum are attracted each other, thereby realizes fixing in the oral cavity of artificial tooth.Denture magnetic maintenance technology need not used metal clasp, have avoid snap ring to damage, the artificial tooth fixation of abutment, pluck and wear advantage simple to operate, easy to clean, that the oral cavity is attractive in appearance, be current stomatologic state-of-the-art technology.Inventor's oral artificial tooth technique for fixing that studies for a long period of time once had ZL00216437X; ZL002166992; ZL002170523; The Patent projects such as ZL2010202191706.Existing magnetic retention technology is that armature keeper is fixed on single the root of the tooth of tooth or residual root both at home and abroad, and each Center stake nuclear in the oral cavity does not connect mutually.The shortcoming of prior art is: abutment required root of the tooth is long, thick, Center stake nuclear is long, if root of the remnant tooth is short, root of the tooth is thin, loosening, then can't fixedly secure, come off easily, need to repeatedly be adhesively fixed, cause the patient suffering, and the expense increase, extremely inconvenient.Therefore invent a kind of short for the oral cavity root of the remnant tooth, undesirable root is thin, root of the remnant tooth is loosening, denture retention is stable, Center stake nuclear difficult drop-off, long service life, pluck and wear simple to operately, easy to clean, easy to use, the comfortable artificial tooth connecting rod magnetic retention device of patient is very necessary.
Summary of the invention
The objective of the invention is: provide a kind of short for the oral cavity root of the remnant tooth, undesirable root is thin, root of the remnant tooth is loosening, denture retention is stable, Center stake nuclear difficult drop-off, long service life, pluck wear simple to operate, easy to clean, the artificial tooth connecting rod magnetic retention device that the patient is easy to use, comfortable.
The object of the present invention is achieved like this:
A kind of artificial tooth connecting rod magnetic retention device is comprised of abutment, artificial tooth, in the stake of abutment undesirable root casting metal center; With metal link rod the metal center stake is connected together; At metal link rod 2-4 armature keeper is set; Artificial tooth is arranged on the base plate; In the bottom of base plate and the armature keeper opposite position on the metal link rod 2-4 Magnetitum is set.
The quantity of metal center stake is 2-4.
Main points of the present invention are: with metal link rod the 2-4 on the abutment undesirable root metal center stake connected together.Bottom at the base plate arranges Magnetitum, and Magnetitum and the armature keeper that is located on the metal link rod are attracted each other; With the denture retention that is located on the base plate.
The present invention arranges 2,3 or 4 metal center stakes according to abutments different in the different patients oral cavity or residual residual root of teeth quantity.
Creativeness of the present invention is: the metal center stake that will be located at first in the world in the oral cavity on several abutments or the residual root links together with the magnetic connecting rod, having changed prior art Center stake nuclear is located on single the root of the tooth, Center stake nuclear is examined unconnected situation with Center stake, has increased retention, the stability of artificial tooth; Can reduce upper and lower jaw basal seat area area, the patient has the minimizing foreign body sensation, and more comfortable sensation is a kind of respond well long-term repair mode.
Center stake of the present invention nuclear refers to imbed after will the metal material casting stake in the root of the tooth; Described armature keeper refers to be arranged on stake nuclear top, is used for the device of attracting each other with the Magnetitum that is arranged on the base plate.Metal link rod of the present invention is cast with a kind of material wherein such as nichrome, titanium alloy, blunt titanium, cochrome, billon; Described Magnetitum is a kind of magnetic material; Magnetitum is welded on the bottom of base plate, and is corresponding with the armature keeper position, attracts each other.Described base plate is with a kind of the making in the materials such as nichrome, titanium alloy, pure titanium, cochrome, billon; Be arranged on the artificial tooth behaviour industry and traffic tooth on the base plate.
The raw material selection of each parts among the present invention, manufacture method, connected mode are existing disclosed prior art.A kind of in the materials such as raw material selection nichrome, titanium alloy, pure titanium, cochrome, billon.
Specific practice of the invention process is:
Requirement to abutment: as long as single jaw tooth has 2 or 2 with upper teeth or residual root, light moderate agomphiasis, root of the tooth long thick be better, tip of a root periodontal is without obvious pathological changes, through improving root canal and observation is unchanged.
Clinical tooth preparation main points: root is grown up in 5 millimeters; Root canal preparation is greater than 4 millimeters; The root face is concordant with the gum edge, and parallel and and biteplane; The neck edge is positioned under the gum about 0.5 millimeter, uses the silicone rubber delivery, fills with into the anhydrite model.Select the magnetic retainers such as fx400, fx600, fx800, made by artificial tooth making center, through examination connecting rod magnetic Center stake nuclear, the secondary delivery is filled with mould and is become the anhydrite model, surveys the center and closes, be made into disjunctor magnetic retention device artificial tooth, repair, try just to wear suitable getting final product behind the tooth.
Advantage of the present invention is:
1. low to the abutment requirement, root of the tooth is short, loosening all can be fixedly secured;
2. denture retention is stable, and Center stake nuclear difficult drop-off increases the service life;
3. pluck and wear simple to operately, easy to clean, the patient is easy to use, comfortable.
