唾液含微生物数可能通过印模和模型对技工的健康造成危害。印模的消毒较为困难，因为容易引起模型变形而导致修复失败。因此，我们取模后在模型室灌注石膏模型，然后对脱模后的托盘、石膏模型分别消毒，以消除病原微生物的危害。其中石膏模型的消毒，我们采用了紫外线光照... Salivary microbe counts may harm mechanics through impressions and models. Stamping disinfection is more difficult, because easily lead to deformation of the model and lead to failure to repair. Therefore, we mold in the model room perfusion gypsum model, and then after demolishing the tray, plaster model were disinfected to eliminate the hazards of pathogenic microorganisms. Which plaster model of disinfection, we use the UV light ...
