About disposable trays
Disposable plastic trays save the time that cleaning and sterilising a tray takes. There are concerns about accuracy with them because they are less rigid in torsion, and the literature also contains findings of comparable accuracy between metal and stock plastic trays. Some disposable trays carry retention fleeces on the inner surface instead of relying on adhesive alone.
Thrown away after one patient, so there is nothing to clean or sterilise. Plastic flexes more, and that flexure risks the material pulling away from the adhesive and distorting the impression.
