Description
Technical Field
The utility model belongs to the technical field of the orthodontic technique and specifically relates to a standard double round tube lingual bracket that dentition alignment stage was used is related to.
Background
In recent years, with the development of orthodontic theory and technology, orthodontic appliances are increasingly innovated and refined, so that people have more and more demand for aesthetic orthodontics. Existing aesthetic orthodontic appliances mainly have: a ceramic bracket appliance, a single crystal bracket appliance, a lingual bracket appliance and an invisible tooth socket.
The ware is rescued in ceramic bracket and single crystal bracket all is in the lip side, and the ceramic bracket is difficult for being perceived by the people and reaching stealthy effect because of its colour is close the tooth true qualities, and the single crystal bracket is nearly transparent, and it is better to glue the disguise on the tooth, makes the process of rescuring to accomplish secretly. But the defects in the art are that a thin metal arch wire can be seen, and the stealth effect has room for improvement. The literature suggests that the thickness of the labial bracket increases the convexity of the lips, which affects the judgment of doctors and also the aesthetic appearance of the side.
The lingual invisible orthodontic technology is an orthodontic technology which is newly developed in recent ten years internationally, and is used for performing orthodontic treatment by mounting all appliances on lingual sides of teeth, and no orthodontic treatment device is visible in appearance. The tongue side bracket appliance is the only appliance which can complete complex cases and has the invisible characteristic clinically at present.
Traditional tongue side holds in palm groove generally is standardized product, holds in the palm the groove bottom plate for the plane, and to every individual tongue face form of tooth generally be curved surface structure and have very big difference, can not laminate completely when traditional tongue side holds in the palm groove bottom plate and pastes on tooth tongue side, need rely on the binder to fill the gap that holds in the palm groove bottom plate and tooth surface, this can cause hold in the palm groove and paste the inaccuracy, hold in the palm the groove and easily drop, correct a series of adverse reactions such as effect is unsatisfactory.
With the development of digital design technology and 3D printing technology, a personalized tongue side bracket manufacturing method has been proposed, i.e., a bracket wax mold is printed by using the 3D printing technology, and then the bracket wax mold is processed by investment casting, but the method has complicated procedures, low efficiency and high cost. In recent years, metal 3D printing technology is becoming mature, and it is proposed to directly print and manufacture personalized lingual brackets by metal 3D printing, but the bracket grooves of 3D printing cannot meet the requirements of clinical application in terms of precision and roughness. If electrolytic polishing or electroplating is carried out after printing to improve the quality of a printing bracket, but the electrolytic machining precision and the machining stability are not high, mainly because the design, the manufacture and the correction of a cathode used in electrolytic machining are difficult, and the cathode is a main factor determining the electrolytic machining precision, so the success rate of groove polishing by using the electrolytic method is not high, and the prior experimental research is limited, and the batch production cannot be realized. Due to the reasons, the manufacturing cost of the personalized lingual bracket is high, and the willingness of common patients to select lingual correction is met to a certain extent, so that the development of lingual correction technology is slowed down.
As an important means of aesthetic orthodontics, the invisible braces are designed into a plurality of pairs of braces in different stages according to the current arrangement condition, occlusion relation and the like of teeth by using computer software, the whole design is very fine, and the requirements on materials and technology are very high, so that the comfort level is very high and the looks are more beautiful. However, contact correction is generally only suitable for mild to moderate dentition and mild bony prominence, and not all cases can achieve the best treatment effect. While most people in China are Mongolian ethnic groups and wrong
The deformity is represented by a protrusion, and the treatment scheme is generally to correct premolar tooth extraction, so for the invisible braces, the conditions belong to complex cases and are easy to derail.
Disclosure of Invention
In order to solve present stealthy effect of correcting not good, with high costs, treatment cycle length and tongue side and correct a series of problems such as the cost is higher, the manufacturing is complicated, the utility model provides a standard double round pipe tongue side support groove that dentition alignment stage used, use the different standard double round pipe tongue side support groove of length in dentition alignment stage promptly, realize the accurate control to the tooth, the doctor's operation of being convenient for of whole treatment process improves patient's comfort level, reduces treatment expense, shortens treatment cycle.
The utility model provides a technical scheme that its technical problem adopted is:
a standard double-round-tube lingual bracket used in the dentition alignment stage comprises a bottom plate, a mesh plate, a long round tube and a short round tube, wherein the bottom plate is in a chamfered isosceles trapezoid shape, the short-edge end of the bottom plate is close to a gum end, the long-edge end of the bottom plate is close to a dental crown end, the shape of the mesh plate is the same as that of the bottom plate, the bottom plate is fixed on the mesh plate, the long round tube and the short round tube are closely attached to the short-edge end of the bottom plate side by side, and the axis of the long round tube and the axis of the short round; the length of the long round pipe is twice that of the short round pipe; the bottom plate is bent into a curved surface approximately parallel to the tooth surface, when the correction is started, the thin arch wire penetrates through the short round pipe to be aligned, and at the later stage of the alignment stage, the thick arch wire penetrates through the long round pipe to accelerate the alignment.
The beneficial effects of the utility model are that:
the standard double-circular-tube lingual bracket is used in the dentition alignment stage, a short circular tube is used when the dentition alignment degree is poor, a long circular tube is used when the alignment is completed quickly, the alignment speed is high, the dentition can be bent simply and more closely, the manufacturing cost is low, the specifications of the anterior denture base grooves are the same, and the burden of a patient is relieved after replacement is omitted; the standard double-round-tube lingual bracket is simple to manufacture, the operation time of a technician is short, and the delay of orthodontic treatment of a patient due to the manufacture of an appliance can be reduced; the lingual bracket of the standard double-circular tube can be combined by different arch wires in the long and short circular tubes, so that the alignment of teeth can be realized by different force values; the design of the round tube ensures that a doctor can achieve the effect of fixing the arch wire without ligating the arch wire, thereby improving the speed of the doctor in the arch wire replacing operation.
