Abstract
The utility model provides an orthodontic bracket with a nano layer. A layer of nano TiO2 ceramic thin film coating is attached to the surface of a bracket body. The defect of overlarge friction force between an orthodontic arch wire and the bracket in the prior art is overcome. Compared with an ordinary metal bracket, the nano TiO2 ceramic thin film coating has the advantages of good surface smoothness and good mechanical performance, and an experiment shows that the friction force between the bracket provided by the utility model and the arch wire is reduced by above 17 percent, so that the clinical requirement of orthodontics can be satisfied, the orthodontic time is shortened, the pain of an orthodontic patient is reduced and the orthodontic efficiency is improved.
Description
Technical field
This utility model discloses a kind of orthodontic bracket that has nanometer layer, is to the improvement of existing orthodontic bracket, belongs to mouth cavity orthodontic apparatus technical field.
Background technology
In mouth cavity orthodontic clinical technology field, using and receiving incisor in the sliding mechanism is the wider means of using in the raw silk rings begg appliance technology, and bracket and arch wire relative motion produce frictional force just becomes the problem that just abnormal doctor pays special attention to.The frictional force that bracket and arch wire relative motion produce is big more, and it is just more little that tooth displacement actual rescued the force rate example, and then influence rectifying effect.
At present, bracket material commonly used has rustless steel, pottery, rigid plastics.They increase with the frictional force that different arch wire combinations are produced successively.For reducing frictional resistance, obtain the most effectively tooth displacement and the righttest biological tissue's reaction, be the task that this patent will solve.
Summary of the invention
This utility model provides a kind of orthodontic bracket that has nanometer layer, has overcome existing orthodontic bow-wire and the excessive shortcoming of bracket frictional force.
The technological solution party of this utility model presses as follows: at surface attachment one deck nano-TiO of bracket body
2The ceramic membrane coating constitutes layer structure.
The good effect of this utility model is: nano-TiO
2The ceramic membrane coating is compared with the common metal bracket; Have surface of good fineness and mechanical property; The frictional force of experiment proof this utility model bracket and arch wire is reduced to more than 17%, can satisfy the clinical needs of mouth cavity orthodontic, has shortened the just abnormal time; Reduce just abnormal patient suffering, improved just abnormal efficient.
Description of drawings
Fig. 1 is this utility model structure principle chart;
Wherein, 1 bracket body; 2 nano-TiOs
2The ceramic membrane coating.
The specific embodiment
According to shown in Figure 1, at surface attachment one deck nano-TiO of bracket body 1
2 Ceramic membrane coating 2 constitutes layer structure.
Claims (1)
