Abstract

The invention discloses a repeated-plastic oral cavity impression tray and manufacturing and using methods. The oral cavity impression tray is prepared from 85-99 parts (by weight) of memory high-polymer material, 0.05-1 part (by weight) of antibacterial agent and 0.05-1 part (by weight) of pigment. The oral cavity impression tray is prepared from the memory high-polymer material through injectionmolding, and the size of the impression tray can be adjusted according to an oral cavity tissue size of a patient, so that the degree of comfort of the patient during impression is increased; the tray is high in deformation, remarkable in memory effect and low in induction temperature and is suitable for being used repeatedly; and the oral cavity impression tray is doped with the antibacterial agent and can be disinfected automatically, so that a disinfection process is avoided, and resources of hospitals are saved.

Description

technical field [0001] The invention relates to the field of oral cavity impression trays, in particular to a replastic oral cavity impression tray and methods for its manufacture and use. Background technique [0002] Oral impression trays are mainly used to place impression materials and are an important tool for making oral tissue morphology models. The existing impression trays on the market mainly include stainless steel trays and plastic trays. These two trays are non-shapeable, and cannot be accurately adapted to the oral cavity for patients with different sizes of oral tissues. At the same time, since the tray is not a disposable consumable, it needs to be used in the mouth of different patients. In order to avoid cross-infection, it needs to be disinfected before each use. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a replastic oral cavity impression tray and its manufacturing and using method...
