Is silicone putty economical for making impression?
I try to calculate unit cost for PVS materials with comparison.
 |
This is GC PVS putty material. It costs for 7837 yen without tax. The capacity is 278ml + 278m;=556ml.
|
 |
| This is PVS injection type and price of 5432 yen/48ml. |
The unit price of the putty type is 14.1 yen/1ml (0.13 dollar/1ml).
The injection type of unit price is 113.2 yen/1ml (1.03 dollar/1ml).
113.2/14.1=8.01. It seem to be eight times of price difference.
It was calculated as 110 Japanese Yen = 1 USA dollar.
When we make impression with PVS, it might be nice to use as much putty as possible and as little injection as possible without sacrifice of accuracy.
APPENDIX:
 |
| This is Zerosil PVS impression material used as our clinical setting. |
It costs 13570 yen/500ml+500ml=1000ml. The unit price of the material is
13.57yen/1ml (0.123 dollar/1ml). The unit price of Zerosil PVS material may be roughly pertinent to the unit price of the putty type mentioned above.
 |
| This type of PVS supplier has always much uselessness in the part of the tip. |
 |
| This type of syringe has always minimum uselessness. |
