Abstract

The invention relates to a daily necessity for tooth health care, and in particular relates to a nickel/titanium alloy bridge-type dental brace which is designed to protect the teeth from food residue, bacterial infection and acid corrosion. A frame of the dental brace is formed by a release spring and a ring-shaped arch wire which are made of a biomedical-grade nickel/titanium alloy. The release spring is made according to the shape of the third molar and placed in parallel with the third molar, and the alloy is activated by the temperature of the oral cavity so that the release spring is fixed on the third molar. The ring-shaped arch wire integrated with the release spring, is made according to the shapes of the gum and the jaw bone and placed around the gum, and the alloy is activated by the temperature of the oral cavity so that a film coated on the ring-shaped arch wire is tightened and fitted on the surfaces of the teeth, the gum and the periodontal area in a double-layer mode, so as to keep the teeth clean. A drug can be loaded on the inner surface of the film to treat tooth diseases and bad breath. The mechanism of the bridge-type dental brace is as follows: the release spring is fixed based on the feature of high elasticity of a shape memory alloy that becomes soft at a low temperature below 25 DEG C and becomes active at a temperature above 32 DEG C, so as to achieve the purpose of fixing the ring-shaped arch wire and the film.

Description

Nitinol bridge-type facing

Technical field:

The present invention is a kind of articles for daily use of dental care.At tooth and the Protean characteristics of dental bed structure, design a kind of widely applicable, easy to use, cheap bridge-type facing, protect the tooth personage for vast love tooth and bring glad tidings.

Technical background:

The puzzlement that the whole world has tens people suffered from by tooth varies at teeth patterning, and the characteristics that vary with each individual break through difference, and innovation could promote a revolution of dental care to some extent.

Summary of the invention:

Material behavior: Nitinol is a widely used material in China's stomatology, wherein memory-type arch wire performance is particularly outstanding, the memory-type arch wire is easy to deliquescing at room temperature (about 25 degree) and following temperature, and return to original preforming shape more than reaching uniform temperature (about 32 degree), show shape memory and add super elastic characteristics, just because of this specific character, it is maintained room temperature and following state of temperature, can the easy manipulation molding, and to be placed to assigned address be oral cavity dental bed and third molar position, and after receptor warm amount in oral cavity activates, can produce the shape restoring force, provide required strength by fixing teeth and dental bed again. because of the memory-type arch wire is had the cold deliquescing of chance, be subjected to hot activation and the big characteristics of the elasticity that becomes, utilization is sucked cold, and the hot water mode changes bed knife, the convenient use reduced sense of discomfort.

The present invention utilizes the Nitinol excellent properties to make bridge-type facing framework, and framework is made up of with the memory-type cut spring memory-type annular arch wire, both one (with welding or crimping method), below for ease of each self-applying is described, it is separated spy's explanation.

The present invention is a kind of bridge-type facing; during use cut spring placed third molar position, dental bed both sides, oral cavity; its shape designs according to the third molar outline; parallel insertion third molar; body temperature activates spring down; it is fixed on the third molar; memory-type annular arch wire places around the dental bed; its shape is according to whole dental bed jawbone shaped design; body temperature activates annular arch wire down; make the tubular film bilayer that is enclosed within on the annular arch wire be closely buckled in tooth, gingiva, periodontal surface, tooth and region of interest are implemented protection.

The present invention is directed to that food is got stuck between the teeth, tooth is subjected to bacterial infection and acid corrosion has buffer action, gingiva, periodontal are all had good protective effect.

The present invention can insert medicine at facing film inner surface, treatment odontopathy, halitosis.

Bridge-type facing advantage and effect

(1) the present invention is not limited by teeth patterning, adopts ambiguous morphology (thin film) to replace concrete thread form cover;

(2) the present invention not only takes care of one's teeth, and gingiva, periodontal are also had health-care effect;

(3) the present invention adopts the memory-type Nitinol, utilizes variations in temperature to activate alloy, is fixed on the tooth dental bed, and is simple, easy to operate, not only support film but also dental bed do not had injury;

(4) coat medicine at the thin film inner surface, be buckled in tooth, gingiva, periodontal surface, odontotherapy, elimination halitosis are had very good effect.

Description of drawings:

Figure one is upper tooth three-dimensional effect diagram of the present invention, uses during because of the transparent drawing of thin film

Expression

Figure two is lower tooth three-dimensional effect diagram of the present invention

Figure three is frame structure of the present invention, promptly remembers cut spring and the annular arch wire one of memory

1. annular arch wire is remembered in expression; 2. expression thin film; 3. expression cut spring.

The specific embodiment:

(1) the tubular thin film is enclosed within on the annular arch wire;

(2) suck cold water, with the parallel third molar position that is placed on of cut spring, the cold water that spues utilizes body temperature with cut spring, and the thin film end is fixed on the third molar position;

(3) the annular arch wire with the cut spring one places the dental bed bottom, and arch wire is activated by body temperature, tightens thin film and makes its even bilayer be buckled in tooth, gingiva, periodontal surface;

When (4) unloading facing, suck cold water, cut spring is broken in the cut spring deliquescing into two with one's hands, and facing spues;

Thin film: adopt good permeability, the transparency is good, nontoxic, pliability is good, the anti-material of chewing.

Product of the present invention continues to use, and uses the forward and backward disinfection of answering, and guarantees safety, health.

Claims

1. Nitinol bridge-type facing adopts bridge architecture: by the facing framework is the Nitinol cut spring, and Nitinol annular arch wire fuses and the tubular thin film is formed, and the tubular thin film is enclosed within on the annular arch wire.

2. according to claim 1, cut spring is pressed the design of third molar outline, parallel being placed on the third molar utilizes oral cavity body temperature to activate memorial alloy, makes it not only encircle third molar but also push down thin film, the annular arch wire that prevents thin film play and cut spring one is pressed dental bed, the jawbone shaped design is placed on around the dental bed, utilizes oral cavity body temperature to activate memorial alloy, make it tighten thin film, bilayer is buckled in tooth gingiva periodontal surface.

3. according to claim 1, it is the memory-type arch wire that cut spring and annular arch wire all adopt martensite to activate Nitinol, utilize the memory-type arch wire to meet cold deliquescing (25 degree are following) and be subjected to hot activation (more than 32 degree) and the big characteristics of the elasticity that becomes, fixedly separated spring on third molar, thus reach stationary annular arch wire and membrane action.
