Abstract
The utility model relates to a gum protection shoulder prepares car needle, cylindrical car needle body have and are used for the top plane of grinding one's teeth in sleep, outside the plane of top along and car needle body side top between have a circular arc chamfering. The top plane is equipped with a plurality of sharp keen swords, and this every sharp keen sword one end crosses in top plane center, and the other end is followed outside extending to the top plane. The whole wolfram steel material that is of this car needle. The sharp keen sword in top is ground one's teeth in sleep, and it is better than the present diamond dust dull polish mode of grinding one's teeth in sleep that it grinds one's teeth in sleep the effect to, owing to set up circular arc chamfering glossy relatively, can play certain guard action to the gum, and in this embodiment, this car needle wholly can be for the wolfram steel material, it makes this product sturdy and durable, is the general life -span 5 of an ordinary diamond dust shoulder car needle 10 doubly.
Description
Technical field
The instrument that a kind of dentist of this utility model uses, particularly a kind of shoulder car pin.
Background technology
Existing shoulder car pin is generally integrated formed structure, its overall employing corundum material, owing to entirety is very rigid, easily gingiva is caused damage when grinding one's teeth in sleep.Further, the car pin of existing corundum material, although needs of grinding one's teeth in sleep can be met, but, its service life is the shortest.
Utility model content
Of the present utility model being solved the technical problem that i.e. is providing one can either protect gingiva, can meet again needs of grinding one's teeth in sleep, and have the novel gingiva protection shoulder preparation car pin in longer protection life-span.
The technological means that this utility model is used is as described below.
A kind of gingiva protection shoulder preparation car pin, cylindrical car pin body has the top planes for grinding one's teeth in sleep, has circular arc chamfering between top planes outer and car this body side surface of pin top.
Top planes is provided with some sharp keen swords, and this each sharp keen sword one end is intersected in top planes center, and the other end extends to top planes outer
Between adjacent sharp keen sword, there is inside groove；Top planes center has downwards the first groove, and adjacent sharp keen sword and junction, top planes outer have downwards the second groove and the 3rd groove, and this first groove and the second groove and the 3rd groove other end intersect at bottom land, form this groove.
This car pin generally wolfram steel material.
Have the beneficial effect that produced by this utility model: the sharp keen sword in top is ground one's teeth in sleep; its chewing qualities is better than the existing corundum frosted mode of grinding one's teeth in sleep; and; owing to being provided with the circular arc chamfering of relative smooth, gingiva can be played certain protective effect, and; in the present embodiment; this car pin entirety can be wolfram steel material, and it makes this product sturdy and durable, and General Life is 5-10 times of common corundum shoulder car pin.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model top planes structure for amplifying schematic diagram.
Detailed description of the invention
Referring to shown in Fig. 1 and Fig. 2, this utility model one gingiva protection shoulder preparation car pin, cylindrical car pin body 1 has the top planes 2 for grinding one's teeth in sleep, and it focuses on, and has circular arc chamfering 4 between top planes 2 outer 21 and car this body side surface of pin 3 top 31.Top planes 2 is provided with some sharp keen swords 5, and this each sharp keen sword 5 one end is intersected in top planes center 6, and the other end extends to top planes outer 21.Between this adjacent sharp keen sword 5, there is inside groove 7；Top planes center 6 has downwards the first groove 8, adjacent sharp keen sword 5 has downwards the second groove 9 and the 3rd groove 10 with junction, top planes outer 21, this first groove 8 and the second groove 9 and the 3rd groove 10 other end intersect at bottom land 11, formed and this groove 7(figure only depicts two grooves, between the most adjacent sharp keen sword, all there is groove, as a example by the present embodiment accompanying drawing, there are eight grooves).
Said structure; the sharp keen sword in top utilizing rule is ground one's teeth in sleep; its chewing qualities is better than the existing corundum frosted mode of grinding one's teeth in sleep, and, owing to being provided with the circular arc chamfering of relative smooth; gingiva can be played certain protective effect; further, in the present embodiment, this car pin entirety can be wolfram steel material; it makes this product sturdy and durable, and General Life is 5-10 times of common corundum shoulder car pin.
In this specific embodiment, car pin overall length 22mm, it can be divided into the afterbody B of head A and 9mm of 9mm, and centre is connecting portion.Top planes diameter most preferably 0.8mm, a diameter of 1.2mm of car pin body, circular arc chamfering height (i.e. height between top planes and car this body side surface of pin top) is 0.2mm, and sharp keen sword is 8, and it is averagely arranged at top planes, and depth of groove is 0.4mm.Above-mentioned numerical value can the most slightly change, and should not limit this case with this.
Claims (3)
