Disinfection of prints - Aftercare and maintenance
Disinfection of prints
For disinfecting prints and all other engineering work that has been in contact with patient material, a large, lockable container with 0.1% (1000 ppm) hypochlorite is sufficient.
For disinfection of prints and workpieces that are not contaminated with blood, 0.0250% (250 ppm) hypochlorite can be used or a disinfectant that has been specially developed for disinfecting prints. Such a special disinfectant must have a CE number or must be approved as a disinfectant at the Board for authorization of plant protection products and biocides (CTGB).
The prints and other workpieces must be submerged for five minutes. They are then rinsed and packaged for shipment to the dental laboratory.
The hypochlorite is freshly prepared every morning in the right concentration. Carefully follow the manufacturer's instructions. The use of ordinary household bleach water is undesirable because the precise concentration of the chlorine is not clearly defined.
In case of intensive use, the hypochlorite solution must be changed several times per working day.
Various manufacturers put ready-to-use (costly) disinfectants on the market for the disinfection of prints.
A Disinfection liquid for printing. B Chlorine tablets for preparing a solution for disinfection of prints
A Extra strong detergent in tablet form for the DAC. B Sonicflex with insert 'pick' for placement in the Kavo Lifetime
All workpieces that come out of the dental laboratory to be fitted or placed must always be rinsed first under running water and then disinfected with 70% alcohol.
