It was our impression from viewing the video that this technique is very dependent on the dentist's skill in performing the needed steps (more so than with conventional construction, primarily due to time constraints needed to accomplish certain steps, and accomplish them the first time, properly, before the denture materials set). So in that regard, likely the dentist who fabricated your mother's denture is due as much credit as the system itself.
Denture Materials – Your dentures can be made from acrylic, nylon polymer, or cobalt metal. Each material offers its own distinct set of benefits and factors into the price you pay for your dentures. Metal, for instance, is more costly because it’s difficult to break, while denture plates made from acrylic resin are less expensive, more flexible, and can be tinted to match your natural gum line.
