Description

A portable cleaning instrument for fixed oral orthodontics

Technical Field

The utility model relates to the field of oral cleaning, in particular to the field of oral fixed orthodontic cleaning, and specifically is a portable oral fixed orthodontic cleaning instrument.

Background Art

Orthodontics is an effective method for correcting malocclusion. During the orthodontic process, orthodontic brackets need to be attached to the tooth surface and connected with archwires to form fixed braces. However, in actual use, fixed braces need to remain in the patient's mouth for a long time. The acidic environment in the mouth corrodes the teeth, and caries-causing bacteria grow and multiply in the parts of the teeth that are difficult to clean, which leads to the accumulation of oral plaque near the orthodontic brackets and the gaps between teeth. This can lead to tooth demineralization and the formation of white spots on the tooth surface, affecting the appearance and even causing caries.

In the prior art, in order to solve the cleaning problem around the brackets and under the archwires of traditional orthodontic appliances, orthodontic toothbrushes have emerged. The portable orthodontic toothbrushes currently available on the market consist of a cleaning device body and a box body that also serves as a brush handle. The cleaning device body can be installed in the box. When not in use, the cleaning device body can be inserted into the box from one side of the box body to prevent the bristles from being contaminated. When in use, it can be taken out for brushing. There are obvious shortcomings:

Since orthodontic brackets are significantly higher than the surface of teeth, and the step bristles of orthodontic toothbrushes have a fixed length, but the brackets of different types of orthodontic appliances are of different sizes, this will cause the brackets and bristles to not match, resulting in incomplete cleaning around the brackets. The bristle clusters of the toothbrush in the middle are restricted by the position of the brackets, causing the bristles to bend. Not only can the orthodontic brackets and the area under the archwire not be thoroughly cleaned, but the bristles can easily get hooked on the orthodontic brackets, pulling the unstable orthodontic brackets off.

The existing flushing devices can effectively clean food residues and soft scale in hidden areas, and the water flow they generate can massage the gums and enhance the ability of local tissues to resist external stimuli, but they cannot clean the inside of the teeth, and the cleanliness of the gums, interdental spaces and other areas is low. In addition, the flushing devices on the market are large in size, or use external water sources, that is, the pipes are directly connected to the faucet, which puts forward new requirements for hygiene. Therefore, patients who use orthodontic brackets need to use an orthodontic toothbrush combined with a flushing device to thoroughly clean their oral hygiene, but this requires the purchase and use of two devices, which are complicated to operate and inconvenient to carry, making it very difficult to use and causing a waste of time.

Summary of the invention

The utility model provides a portable oral fixed orthodontic cleaning instrument to solve a series of problems in which the existing cleaning devices cannot provide for the thorough cleaning of the area around the orthodontic brackets, under the archwire and between the teeth during use, the cleaning process is cumbersome, the operation is complicated, the cleaning device is inconvenient to carry, and time is wasted in use.
