Description
Technical field
The present invention relates to medical apparatus, specifically a kind of diastema retainer in implantation oral cavity.
Background technology
Children's milk teeth period, causes premature loss of deciduous tooth due to a variety of causes, and mistake is left in deciduous dentition
Diastema, and the deciduous teeth of gap both sides can be tilted because support is lost to clearance side；To jaw
Tooth can gradually extend because no normal tooth stops, can so ultimately result in denture disorder,
Follow-up CV NR is set to be obstructed.
Space retainer is based on this and is used to keep losing diastema, maintains denture form steady
It is fixed.Can solve the problem that because premature loss of deciduous tooth bring the problem of.
Although existing space retainer species is a lot, trouble, technique letter are often made
Plain, fixed unstable, concurrent odontopathy is more and causes clinical therapeutic efficacy not good enough.For example,
Fig. 5 and 6 is a kind of existing space retainer, including is enclosed on remote middle side tooth (in figure
For the tooth on the left of missing tooth) on band and wire ring in missing tooth tooth position, this
Side tooth (being the tooth on the right side of missing tooth in figure) during wire ring gentle touchdown is near.
In addition, existing space retainer needs to be carried out a pair according to patient's denture form modulus
One makes, and technique is cumbersome, and critical piece needs manually to bend, and its precision and comfort level depend on
The personal experience of Yu doctor and technology.Wherein movable space retainer, which makes, need to use self-solidifying
There is peculiar smell after resin, making, resin has aging metaboly, volume in use
Greatly, pluck and wear inconvenience, children often refuse to wear；Wire ring formula retainer needs to wear band,
Band volume is big with weight, and foreign body sensation is strong, and comfort level is not good enough, easily stimulates gum, band
Secondary caries, easy to fall off during rescuing, the wire ring pad that steel wire is bent easily occur around ring
It is easy to crack.
The content of the invention
Present invention aim to address deciduous teeth space retainer technique it is cumbersome, depend critically upon doctor
The problems such as giving birth to experience and technology, wear discomfort.
To realize that the technical scheme that the object of the invention is used is such, one kind universal half
Wire ring formula space retainer, it is characterised in that:Including support bar, base, sliding sleeve and clamp screw
Nail.
One surface of the base is bonding plane B, another surface connection sliding sleeve.
There is set hole and screwed hole on the sliding sleeve.The set hole is one and runs through sliding sleeve two ends
Through hole.One aperture of the screwed hole is covering the hole wall in hole, another aperture in set hole
Outer wall.
The support bar is divided into first paragraph, second segment and the 3rd section.
The first paragraph of the support bar through set hole in.The second segment of the support bar is the bottom of to
The bending of seat direction.
The 3rd section of the support bar is bent to base direction.The 3rd section of back of the body of the support bar
It is contact surface A to the side of base.
The holding screw is screwed in from screwed hole.
Further, the support bar, base and sliding sleeve are made up of titanium alloy.
Further, there is indentation staggeredly on the bonding plane B.
The solution have the advantages that unquestionable：
1) use titanium alloy as apparatus main body material, small volume is lightweight, overcomes foreign matter
Problem that sense is strong, comfort level is not good enough；Device free from extraneous odour；
2) device is bonded in dental surface, small with teeth contact area, and gum will not be stimulated to stick
Film and generation secondary caries；
3) device is connected using slideway with rod-type, and a word screw is fixed, can be big for gap
Small progress length adjustment and interception, save one-to-one making, without modulus type, bring and use,
Precision is good, is not required to bend；
4) slideway and base casting, in the absence of later stage problem of Cracking.

Embodiment
With reference to embodiment, the invention will be further described, but should not be construed this
Invent above-mentioned subject area and be only limitted to following embodiments.Think not departing from above-mentioned technology of the invention
In the case of thinking, according to ordinary skill knowledge and customary means, various replacements are made
And change, it all should include within the scope of the present invention.
Referring to Fig. 1 and 2, a kind of universal half wire ring formula space retainer, including by medical titanium
Support bar 1, base 2, sliding sleeve 3 and holding screw 4 that alloy material is made.
Referring to Fig. 3, the base 2 is a rectangle or the metallic plate of other shapes, one
Surface is bonding plane B, another surface connection sliding sleeve 3.In embodiment, have on bonding plane B
There is indentation staggeredly as shown in Figure 4, in use, can use the agent of gear division special bonding will
Bonding plane B is fixed at 1/3 in the corona buccal aspect of the remote middle side tooth of gap.
See also Fig. 3, the sliding sleeve 3 is the metal derby of a strip, and its lower surface is consolidated
It is scheduled on base 2.There is set hole 301 and screwed hole 302 on the sliding sleeve 3.The set hole
301 be a through hole (length direction for running through sliding sleeve 3) through the two ends of sliding sleeve 3.It is described
One aperture of screwed hole 302 is covering the hole wall in hole 301, another aperture in set hole 301
Outer wall.
The support bar 1 is divided into first paragraph 101, second segment 102 and the 3rd section 103.
The first paragraph 101 of the support bar 1 through set hole 301 in.The support bar 1
Second segment 102 bent to the direction of base 2, and be in α with the first paragraph 101 of support bar 1
°。
The 3rd section 103 of the support bar 1 to the direction of base 2 bend, and with support bar 1
Second segment 102 be in β °.
What deserves to be explained is, the 3rd section 103 of the support bar 1 is stretched into the tooth institute of missing
In the gap stayed, the side of the 3rd section 103 of the support bar 1 dorsad base 2 is contact
Face A.1/3 gentle touchdown but not in the corona distal surface of side tooth during contact surface A and gap are near
Make contacted tooth by extra-push model.
In embodiment, α ° and β ° of angle can roll over according to actual conditions hot bending.For example
In figure, α °+β °=270 °, α °=150 °, β °=120 degree.
In embodiment, after the holding screw 4 is screwed in from screwed hole 302, fastening is described
Holding screw 4, the first paragraph 101 for making it compress the support bar 1 in sliding sleeve 3.I.e. so that whole
The length of individual device is fixed, and reliably keeps the length of gap between two teeth, and can be according to tooth
Corresponding micro-adjustment is done in the change of gap length caused by row growth change, treats relevant position
It is i.e. dismountable after CV NR.
