Cleaning method of intraoral wearing device and cleaning agent composition for intraoral wearing device

The present invention relates to a method for cleaning an intraoral wearing device and a cleaning agent composition for an intraoral wearing device.

With the progress of super-aging in recent years, the number of people who are obliged to wear removable oral devices such as dentures is acceleratingly increasing. Such intraoral wearing devices, such as dentures and orthodontic devices, tend to retain solid stains such as oil stains and dental plaque that adhere during wearing. Especially at the end of the intraoral wearing device having a complicated shape, it is difficult to remove the dirt and it remains firmly adhered. In addition, if the oral cavity wearing device is worn with these stains remaining, bad breath, caries, periodontal disease and the like may be caused.
Therefore, in order to maintain the health of the body, it is necessary to keep the intraoral wearing device clean, and daily delicate cleaning is indispensable.

Various compositions and cleaning methods have been developed in order to effectively clean such an intraoral wearing device. For example, Patent Document 1 discloses a cleaning agent containing lysozyme chloride filled in a container that can be ejected in the form of bubbles, and Patent Document 2 disperses it in the form of air-permeable bubbles. Cleaning prescriptions have been disclosed, and attempts have been made to improve the cleaning effect and shorten the cleaning time.
Further, Patent Documents 3 to 4 disclose liquid compositions containing a surfactant, which are contained in a container for ejecting the composition in the form of foam, and are applied in the form of foam at the time of use. It is also described that a rapid stain removing effect can be exhibited.

It means a so-called dental attachment that needs to be attached and detached in the oral cavity. Specifically, for example, a full denture (total denture) is a denture to be attached to a toothless jaw, and is composed of an artificial tooth and a denture base. On the other hand, removable partial dentures (partial dentures) are dentures to be attached to jaws with partially lost teeth, and are composed of artificial teeth, denture bases, and abutment devices such as clasps, rests, and attachments.
