The invention relates to a disposable movement tooth protecting socket and a preparation method thereof. The preparation method of the disposable movement tooth protecting socket disclosed by the invention comprises purification and modification of konjac glucomannan, preparation of compound gel, degasification, molding and drying. The konjac glucomannan is taken as a carrier and assisted by other assistants; the disposable movement tooth protecting socket has excellent film-forming property, water-tightness, antibacterial property, large tensile strength, and good toughness; the konjac glucomannan is taken as a main material of the disposable movement tooth protecting socket. Compared with the existing movement tooth protecting socket, the disposable movement tooth protecting socket is high in tensile strength, and high in acid and alkali resistance, high-temperature resistance and antibacterial effect. The product is not degraded under normal use, can be completely degraded in soil under the conditions such as water, carbon dioxide, microorganisms, temperature and the like, is short in degradation time, convenient to draw materials, low in price and simple in production technology, accords with the national environment-friendly and low-carbon policy, and accords with the processing and production requirements of the disposable product. The disposable movement tooth protecting socket also has excellent performances such as antibacterial property, water resistance, breaking resistance, softness and the like.
