diffi cult for hospitals to justify the investment. As with all treatments, the
costs must be balanced against the benefi ts.
6.9.6 Conclusions
As reported by other researchers, the principal benefi ts observed in this
research are increased comfort and speed of the process compared with the
traditional impression (9, 10). The scans took no more than a few minutes
of the patient’s time and presented no discomfort or distress. The time
saving also benefi ts the prosthetist.
The vacuum-forming moulds produced by LOM TM and CNC require no
special treatment. The production of the moulds from the scan data presented
no inconvenience to the prosthetist and they could be delivered in
a matter of days in most circumstances.
